A Cova das Choias

A Pobra do Brollón

A Cova das Choias is a karst cave in the municipality of A Pobra do Brollón, in the province of Lugo, on the edge of the Ribeira Sacra area bordering the Sierra do Courel. It sits in the parish of Óutara, close to the hamlet of Biduedo, and stands out as one of the most unusual natural sites in this part of Galicia, combining raw geology with centuries of mining history. How do you get there? The approach runs through Biduedo: drive the paved road to where it ends, then continue on foot along a dirt track toward the cave entrance. The terrain is mountainous, so sturdy footwear and extra time are worth planning for. Independent exploration of the interior isn't allowed — access is managed by the local town council (concello), which runs seasonal guided visits to protect the site. What will you see inside? The cave unfolds across three levels, with passages and chambers totaling over 100 metres, roughly 20 metres wide, and a vault that tops 30 metres in height in places. The middle level is generally considered the most rewarding, showing off rock shapes carved by water alongside clear traces of past human digging. Several galleries are dead ends, adding to the sense of a natural labyrinth. The cave's standout feature is Schistostega pennata, better known as goblin gold moss — in low light its cells reflect a faint golden-green glow, a rare optical trick found in only a handful of places worldwide. The cave also shelters bat colonies, another reason behind the strict limits on casual entry. Where does the name come from, and what's the history? The name comes from "choias," the Galician word for red-billed choughs — crow relatives with a curved, bright-red beak that have long nested near the cave mouth. While the cave itself formed naturally through water and wind erosion of limestone, much of its interior was shaped by mining. Iron ore was extracted here first during Roman times, between the 1st and 3rd centuries AD, and then far more intensively in the 16th and 17th centuries, when the ore fed forges and ironworks across the Lemos region. That mix of natural formation and industrial archaeology is what makes Cova das Choias distinctive, beyond its scenery alone. When should you visit, and how does it work? Because the ecosystem inside is fragile — the glowing moss and the bat colonies in particular — access has been restricted for several years. Visits are only possible through the seasonal guided-tour programme run by the A Pobra do Brollón town council, typically scheduled during the summer months. Exact dates shift from year to year, so it's worth checking the current schedule directly with the council or on its website and booking ahead, since each tour takes a limited number of visitors. Frequently asked questions Can you visit the cave on your own? No. For several years now, entry has only been possible on a guided tour organised by the local council, mainly during summer. Why is the cave called "Choias"? It's named after red-billed choughs, crow relatives with curved red beaks that traditionally nested at the cave's entrance. What's the main highlight inside? The glow-in-the-dark moss Schistostega pennata, along with remnants of iron mining dating back to Roman times and continuing into the early modern period. How do you reach the cave? Through the hamlet of Biduedo — follow the paved road to its end, then continue on foot toward the entrance.

Sima de los Simancos

Cabrejas del Pinar

Sima de los Simancos is a cave located in the municipality of Cabrejas del Pinar, in the province of Soria, in the Castile and León region of Spain. It's one of the more notable caving sites in the area, known to local speleologists and visited by caving enthusiasts, though it does call for some basic preparation and gear before heading in. What will you find inside? The interior consists mainly of a single long gallery running roughly east to west, sloping gently downward. The tunnel keeps fairly consistent proportions throughout — about 4 metres wide and 6 to 8 metres high — giving the sense of moving through a natural stone channel. Deeper in, you'll come across gravel deposits and accumulated branches, carried in by water whose flow noticeably picks up during the rainy season. The cave also serves as an important shelter for bats. Large patches of guano in several sections point to it being used as an overwintering site for a bat colony. Bones of livestock — sheep, goats, and even mules — have also been found on the cave floor, suggesting the space was historically used as a natural pen or shelter for herds. How do you get there? Three entrance shafts lead into the cave. The main one, and the best equipped for descent, is known as P18 — roughly 18 metres deep, dropping vertically onto a large debris cone at the base, mixed with branches and organic sediment. Descending through this shaft requires proper caving equipment (harness, ropes, helmet with a headlamp) and is best done with someone who knows the terrain, or with an organised caving group — this isn't a site suited to unguided, inexperienced visits. Cabrejas del Pinar itself sits in Soria province, surrounded by the extensive pine forests typical of this part of Castile. It makes a good base for anyone curious about the geology hidden beneath the interior of the Iberian Peninsula, where numerous caves and sinkholes — a "sima" in Spanish literally means a deep pit or chasm — form a network of underground attractions. When should you visit? The dry season — late spring through summer and into early autumn — is the best time to explore, when water levels inside are lower and moving through the gallery is safer. During heavy rains, the water flow through the tunnel increases considerably, making entry harder or sometimes impossible. Winter is also worth factoring in: that's when the bat colony overwinters inside, so it's worth keeping noise down and limiting time in the deeper sections out of respect for the animals. Frequently asked questions Is Sima de los Simancos suitable for beginners? Not entirely. Descending through the P18 shaft requires basic caving gear and some prior experience. Anyone without preparation should join a guided group or a local caving club instead of going alone. How long does it take to explore the cave? It depends on the route and how much you want to see — a short look at the main gallery can take one to two hours, while a fuller exploration of the system, including access and return, takes longer. Do animals live in the cave? Yes, it functions as an overwintering site for a bat colony, visible from the large guano deposits in parts of the tunnel. Visitors should stay quiet and respectful of this natural habitat. What does the name "Sima de los Simancos" mean? "Sima" is the Spanish word for a deep cave or chasm, typical of limestone terrain. The name "Simancos" most likely refers to a local place name tied to the surrounding land within the municipality of Cabrejas del Pinar.

Cova de l'Escaleta

Camarasa

Cova de l'Escaleta is a small cave set into a rock wall near Camarasa, a village in Lleida province, in the Catalan comarca of Noguera. The cave sits within a well-known climbing area that has grown steadily over the years on the limestone walls above the Segre valley. The cavity itself is modest and isn't set up for guided tours in the usual sense — what draws visitors here is the surrounding rock: compact, high-quality limestone carrying dozens of climbing routes on either side of the cave mouth. What will you see there? Cova de l'Escaleta marks the left-hand edge of one of Camarasa's newer climbing sectors. The cave is a shallow hollow in the wall, with routes equipped on both sides of it, so climbers pass right by its entrance on their way up. The sector holds around 35 routes ranging from V+ to 7c, making it approachable for climbers just starting on limestone as well as more experienced ones. The wall faces south, and most lines run over 20 metres, with a real variety of holds — small technical footholds, water-carved pockets, and large, comfortable jugs. The sector forms part of a larger climbing area around Camarasa that has kept expanding in recent years, including the neighbouring El Solarium sector roughly 200 metres away. Routes at Cova de l'Escaleta were bolted by local and visiting climbers, with equipment — including a dozen anchor sets — donated by supporters of the climbing scene. The area is set to be included in the next edition of the Lleida climbing guidebook. How do you get there? Camarasa lies in Lleida province on the banks of the Segre river, close to the Camarasa reservoir (Embassament de Camarasa), one of the area's best-known landmarks. The village is reached via local roads connecting it to Balaguer and the rest of the Noguera comarca. The climbing walls themselves, including Cova de l'Escaleta, sit a short distance from the village centre, among the rocky hills that flank the valley. When should you visit? Because the wall faces south, the best climbing conditions come in autumn, winter and early spring, when the sun warms the rock without overheating it. In summer the sector can get too hot at midday, so it's worth timing a visit for the morning or late afternoon. Non-climbers can still combine a stop here with a visit to the Camarasa reservoir or a longer walk through the Segre valley. Frequently asked questions Do you need to climb to see Cova de l'Escaleta? The hollow itself can be viewed from below, but climbers using the surrounding routes get the closest look at it. Who are the routes in this sector suited for? With grades from V+ to 7c, the sector welcomes a wide range of abilities, from newcomers to sport climbing to more seasoned climbers. Is there anything else to see nearby? Yes — the El Solarium sector sits close by, and the Camarasa reservoir, popular with visitors to the Segre valley, is a short distance away. Do you need your own climbing gear? Yes. The routes are bolted with fixed protection (quickdraws' anchors and lower-off points), but climbers need to bring their own personal gear and ropes.

Coves de Serinyà

Serinyà

Coves de Serinyà is an archaeological park in the town of Serinyà, in the Pla de l'Estany region of Catalonia, about 5 kilometers north of Banyoles, right beside the C-66 road toward Besalú and Olot. It ranks among the most significant Paleolithic sites in Catalonia, with evidence of human presence stretching back more than 200,000 years, and the caves have long been a focus of archaeological research. What is there to see in the park? The park occupies a slope built up from travertine (calcareous tufa), a soft limestone-like rock in which nature carved out several rock shelters and caves. These natural hollows once gave Stone Age humans shelter from the weather and from predators. A visit takes you into three of the caves open to the public, and past the reception building, which houses a conference room and an audiovisual area. Inside the reception building is a permanent exhibition on the daily life of Upper Paleolithic hunter-gatherers. Reconstructions and replicas of the archaeological finds help visualize how the groups that once lived in this landscape actually spent their days. The park opened to the public on 26 July 1997. How do you get to Coves de Serinyà? The park sits directly on the C-66, the road linking Banyoles with Besalú and Olot, which makes it an easy stop by car from anywhere in the Girona area. The drive from Banyoles takes only a few minutes, passing through the rural landscape typical of Pla de l'Estany. It works well combined with a visit to Lake Banyoles or the medieval town of Besalú, both nearby. When should you go, and how does a visit work? The caves can only be visited as part of a guided tour — there is no self-guided access. During the summer months the park is often open daily, roughly from 10:00 to 19:00, while outside the high season it usually runs on a reduced schedule, mainly weekends and shorter hours. In spring (April–May), guided tours run on Sundays at set times, and in July and August departures become more frequent, with guides leading groups several times a day. Because the schedule shifts with the season, it is worth checking current hours before setting off. Plan for at least an hour on-site — the guided walk through the caves and the exhibition takes roughly that long, and in summer, when the park draws more visitors, it helps to arrive a little ahead of your tour time. Who is this park suited for? Coves de Serinyà appeals both to families with children and to anyone with an interest in archaeology and prehistory. The guided tours are accessible without any prior specialist knowledge, and the audiovisual exhibition gives a useful introduction to the Stone Age before visitors step into the caves themselves. Because the ground inside the caves is natural and uneven, comfortable, sturdy footwear is a good idea. Frequently asked questions Can you visit the caves on your own, without a guide? No — entry to the caves is only possible as part of a guided tour. How many caves can you see during a visit? Three caves within the park are open to visitors. How far is the park from Banyoles? It's about 5 kilometers north of Banyoles, on the C-66 road toward Besalú and Olot. Is the park suitable for children? Yes, the exhibition and guided tours are family-friendly, and the Stone Age life reconstructions tend to hold younger visitors' attention well.

Cova de la Petxina

Bellús

Cova de la Petxina is a cave in Bellús, in the Vall d'Albaida valley of the Valencia region, known for its prehistoric rock art and traces of human occupation stretching back to the Paleolithic. Together with the nearby Cova Negra in Xàtiva, it forms part of the UNESCO World Heritage listing for the Rock Art of the Mediterranean Basin on the Iberian Peninsula, inscribed in 1998. The site sits beside the Estret de les Aigües gorge, where the waters of the Micena, Clariano and Albaida rivers converge, cutting through the Serra Grossa mountains. What will you see? The main cave, Cova Gran de la Petxina, is a shallow, hemispherical rock shelter roughly 20 metres wide, 26 metres deep and up to 7.5 metres in height. Inside, two distinct styles of prehistoric art survive: schematic art, featuring simple human figures and bar-like motifs, and Levantine art, created during the Neolithic period around 4000 BCE. Excavations have uncovered roughly 1,300 stone tools, mostly scrapers used for working wood and meat, showing that people were present here as far back as 40,000 years ago, during the Mousterian phase of the Middle Paleolithic. This makes it the oldest known archaeological site in the entire Vall d'Albaida region. Beyond the cave itself, the surrounding Estret de les Aigües gorge is worth exploring on its own — steep rock walls hemming in the converging rivers create a landscape valued for its natural, geomorphological and ecological significance, popular with climbers and landscape photographers alike. How do you get there? Access to the cave and gorge starts from a marked path near kilometre 172.5 of the N-340 road, close to Bellús. The trail follows the riverbed and doesn't require technical equipment, though sturdy hiking shoes are recommended, as the ground can be rocky and occasionally damp. What can you do nearby? The rock faces around Estret de les Aigües are a well-known sport climbing spot, with a local climbing area offering routes of varying difficulty. The wider region also draws hikers and cyclists — a network of trails links Bellús with nearby Xàtiva and other towns in the Vall d'Albaida, making it easy to combine a visit to the cave with outdoor activity. When should you visit? Spring and autumn are the best seasons, when temperatures across the Valencia region are mild and river levels make crossing the gorge comfortable. In summer, the exposed rock faces heat up quickly, which can make midday climbing uncomfortable, while winter can bring higher water flow after rainfall. Frequently asked questions Is entry to the cave free? Yes — the cave and surrounding area are reached via a public hiking trail with no admission fee, since it's a natural landscape site rather than a ticketed attraction. Do you need climbing experience to reach the cave? No. The cave itself is accessible on foot along a marked path. Climbing experience is only needed if you plan to tackle the sport climbing routes on the surrounding rock faces. What's the difference between the schematic and Levantine art in the cave? Schematic art consists of simpler, more abstract depictions, such as basic human figures and bar motifs, while the Levantine art from the Neolithic period shows more developed, though still stylised, figures. Can Cova de la Petxina be combined with other nearby attractions? Yes — the UNESCO-listed Cova Negra in Xàtiva is close by, making it possible to plan a day trip that combines both sites along with the Estret de les Aigües landscape.

Cova del Gat

Figuerola del Camp

Cova del Gat is a small archaeological cave located in the municipality of Figuerola del Camp, in the Alt Camp region of Catalonia. It sits on the grounds of the Mas d'en Llop farmstead, roughly four kilometres from the village centre, and is listed in Catalonia's Inventory of Archaeological and Palaeontological Heritage. What is this place? The cave's entrance is only about a metre wide and partly shielded by large limestone blocks, making it easy to miss unless you already know where to look. People used the cave as far back as the Eneolithic period (Copper Age): excavations show it served as a collective burial site around 2000 BC, at the transition between the Copper Age and the early Bronze Age. The site was first studied scientifically in 1934 by Catalan archaeologist Salvador Vilaseca, who classified it as an Eneolithic-period burial cave. Later rescue excavations, carried out in 2006 and 2009, confirmed and expanded on this picture, producing new data on the cave's continued use as a burial place into the early Bronze Age. What has been found inside? Archaeological work at Cova del Gat has uncovered a substantial set of grave goods: pottery fragments decorated with cord impressions and button motifs, flint tools including knives and awls, bone implements, arrowheads, and pieces of necklaces. This kind of funerary equipment is typical of prehistoric communities that inhabited inland Catalonia during this period, and it lets archaeologists reconstruct burial customs and craft skills from the Copper Age and early Bronze Age in the Alt Camp region. How do you get there? Cova del Gat lies in the rural countryside surrounding Figuerola del Camp, a few kilometres from the village centre, amid the fields and low limestone hills typical of inland Catalonia. Because of its archaeological importance, the cave is not open for casual visits. Anyone wanting to see it can request the key from the Figuerola del Camp town hall (Ajuntament) — this is the standard procedure for accessing the site. When should you visit? Given the setting — a small cave in open farmland with no visitor infrastructure — spring or autumn is the best time, when temperatures around Tarragona are mild and walking across the fields isn't hampered by summer heat or winter rain. It's worth contacting the town hall in advance to confirm key availability and arrange a suitable time. Why visit Cova del Gat? This isn't a polished tourist attraction with marked trails and signage — it's a genuine, still-studied archaeological site that offers a direct window into the lives and burial customs of communities who lived in this landscape roughly four thousand years ago. For anyone interested in Catalonia's prehistory and field archaeology, it's a rare chance to see a Copper Age burial site in its natural, largely undisturbed setting. Frequently asked questions Is the cave open to visitors? Not on a walk-in basis — the cave is kept closed, but the key can be borrowed from the Figuerola del Camp town hall. What was found inside Cova del Gat? Pottery fragments with cord decoration, flint and bone tools, arrowheads, and necklace pieces, all linked to burials from the Eneolithic and early Bronze Age. Who first studied the cave? Catalan archaeologist Salvador Vilaseca in 1934, followed by rescue excavations in 2006 and 2009. How far is the cave from the centre of Figuerola del Camp? About four kilometres, on the grounds of the Mas d'en Llop farmstead.

Cueva del Maragato

Cepeda la Mora

Cueva del Maragato is a small rock shelter right on the N-502 road, next to the village of Cepeda la Mora in the province of Ávila, on the northern foothills of the Sierra de Gredos. It combines two things travellers rarely find together: a notable geological feature and the legend of one of Spain's most famous 19th-century bandits. What exactly is this place? The cave itself is modest — roughly 10 metres deep, more of a natural rock shelter than a cave system you can explore at length. Its real value lies in its position: from the opening you can watch the road connecting Ávila with Arenas de San Pedro, which in the past made it an ideal lookout for anyone wanting to spot travellers without being seen. The site is registered in Spain's Inventory of Places of Geological Interest (IELIG) under code Cls065, described as an episyenite outcrop — a rare type of igneous rock — which makes it a worthwhile stop for geology enthusiasts as well as history buffs. Where does the name Maragato come from? The cave is named after Pedro Piñero, known as "El Maragato," a bandit from the Maragatería region in the province of León who was active in the early 1800s. According to the story, he preyed on travellers along this route until he tried to rob a Franciscan friar from the monastery in Arenas de San Pedro. The friar overpowered him instead, and the capture became famous well beyond the region — Francisco de Goya painted the episode in a well-known series of works. Pedro Piñero was tried and executed in the Plaza de la Cebada in Madrid in 1807. How do you get there? Cueva del Maragato sits directly on the N-502, between Ávila and Arenas de San Pedro, close to Cepeda la Mora, a village perched above 1,500 metres at the edge of the Sierra de Gredos. It's an easy stop if you're already driving this road — no long hike or special preparation needed to reach the shelter itself. What else is there to see nearby? The local council has developed the area for visitors, adding a viewpoint at Belverde, an information point, and marked routes leading to and around the cave. It's a convenient base for further exploration of the Sierra de Gredos, a range known for its granite peaks, glacial valleys, and hiking trails ranging from easy walks to demanding mountain routes. When is the best time to visit? Given the altitude and mountain terrain, spring and autumn offer the most comfortable conditions and the clearest views over the surrounding landscape. In summer, the elevation keeps temperatures milder than in the lower parts of Ávila province, while winter can bring difficult driving conditions on the approach roads due to mountain weather. Frequently asked questions Can you actually go inside the cave? Yes. It's a shallow, accessible rock shelter rather than a deep cave system, so no special equipment or caving experience is needed to see it. Is the legend of El Maragato based on a real person? Yes. Pedro Piñero "El Maragato" was a real bandit, tried and executed in Madrid in 1807. His capture was later immortalised in paintings by Francisco de Goya, which helped cement the story in Spanish popular culture. What does "episyenite" mean in the context of this site? It's a geological term for a rare type of altered igneous rock found at this location. Because of its scientific interest, the site is listed in Spain's inventory of geologically significant places. Are there other attractions nearby? Yes. Cepeda la Mora sits on the edge of the Sierra de Gredos, with further hiking routes and viewpoints in the area, including the one developed at Belverde.

Cau de les Goges

Sant Julià de Ramis

Cau de les Goges is an archaeological site in Sant Julià de Ramis, in the province of Girona, sitting on the left bank of the Ter river. It's a modest rock shelter, but one with outsized scientific weight — this is where the Upper Solutrean period of the Paleolithic was first identified and documented in Catalonia. What exactly is this place? Cau de les Goges is listed as a cultural asset of national interest and protected as an archaeological zone. It was discovered in 1899 by Viñas and Carles de Palol, who found flint tools attributed to the Upper Paleolithic. Systematic excavations followed in 1920, carried out by Maties Pallarés and Paul Wernert, who dated the occupation layer to the Solutrean period, roughly 19,000–16,000 BC. The deposit itself is estimated at around 18,000 years BP. The finds suggest the shelter was used as a temporary hunting station — people stopped here briefly during hunting expeditions, leaving behind small tools and traces of activity in and around the site. Cau de les Goges vs. Cova de les Goges — don't mix them up Two similarly named sites exist nearby, and it's worth telling them apart. Cau de les Goges is the archaeological shelter described here. Close by once stood Cova de les Goges, a separate site that was destroyed during the widening of the N-II highway. The names get confused, but only the Cau survived — the Cova is gone. The legend of the goges The site's name comes from a local legend about the goges — mythical female beings, comparable in folk belief to water spirits or water-women found in other cultures. According to local tradition, the cave was their dwelling, giving this modest archaeological spot an extra layer of folklore. How to get there? Cau de les Goges lies within Sant Julià de Ramis, a town just north of Girona in the Ter river valley. The site forms part of a broader walking route through the congost (gorge) and the hill of Sant Julià de Ramis, which links several natural and historical points of interest in the area, including this shelter. The easiest approach is from Girona, only a few kilometres away. What will you actually see? This isn't a developed show-cave with lighting or a marked visitor circuit — Cau de les Goges is a small rock shelter valued for its scientific significance rather than dramatic rock formations. Come here to connect with the story of the region's earliest human occupants and to enjoy the scenery of the Ter valley, not expecting a spectacular cave experience. When to visit? Since visiting means walking a trail through rocky, hilly terrain, spring and autumn are the best times, when temperatures stay moderate and the path isn't baking under the summer sun. Catalonia can get very hot in summer, which makes longer walks less comfortable. Frequently asked questions Is Cau de les Goges a show-cave with a visitor route? No. It's an archaeological site of scientific importance without tourist infrastructure like lighting or guided tours — you visit it as part of a walking trail through the landscape. What's the difference between Cau de les Goges and Cova de les Goges? They are two different, similarly named sites. Cova de les Goges disappeared during the widening of the N-II highway, while Cau de les Goges survived and is protected as a cultural asset. Why does this place matter for archaeology? It's where the Upper Solutrean period of the Paleolithic was first identified and documented in Catalonia, based on excavations from 1899 and 1920. Where does the name "Goges" come from? It comes from a local legend about the goges, mythical female water-spirits said to have inhabited the cave.

Forat del Gel

Llimiana

Forat del Gel is a cave in Llimiana, a small municipality in the Pallars Jussà region of Catalonia. It sits on the northern slope of the Montsec de Rúbies massif, between the peaks of Tossal de la Torreta and Tossal de Mirapallars. The Catalan name translates to "Hole of Ice," a fitting label for the phenomenon that draws cave enthusiasts here throughout the year. What will you see inside? The entrance to Forat del Gel is marked by a striking portal roughly 10-12 meters high, visible from a good distance away. Behind it stretches a single wide, elongated gallery that descends steeply into the hillside — the whole system runs about 200 meters in length and reaches nearly 60 meters in depth. The main draw is the ice formations that give the cave its name. Water seeping through the rock walls freezes wherever cold air stays trapped at a consistently low temperature, building up ice stalactites and flowstone-like formations. They are most visible in winter, on the right side of the main gallery, where dripping water hardens into distinctive icicles and columns. The cave also carries a layered history. Archaeological work has uncovered remains from the Neolithic, Bronze Age, Roman, and Medieval periods, evidence of human presence here across many millennia. During wartime, the cave served as a natural hideout, adding a lesser-known chapter to its story. Near the entrance grows Timmia megapolitana, a critically endangered moss species. This is the only confirmed location of the species on the entire Iberian Peninsula, making Forat del Gel a site of real interest for botanists and conservationists as well as hikers. How do you get to Forat del Gel? The cave lies within the Montsec massif, in the municipality of Llimiana in Lleida province. Access is usually on foot, via a trail crossing the slopes of Montsec de Rúbies — the route forms part of loops popular with local hikers that link nearby summits such as Tossal de la Torreta and Tossal de Mirapallars. Given the steep approach and rocky terrain, sturdy trekking boots and enough time in your schedule are worth planning for. When should you visit? Winter and early spring are the best times to visit, when the ice formations deep inside the cave are at their most developed and dramatic. In summer, the interior stays cool regardless of the season outside, making it a pleasant stop during hikes across the sun-exposed slopes of Montsec. Keep in mind that exploring the deeper sections requires proper caving preparation and equipment, so for most visitors the entrance area — with its distinctive rock portal — is the highlight worth seeing. Frequently asked questions What is Forat del Gel? It's a cave in Llimiana within the Montsec massif, known for the ice formations that build up inside it and for archaeological finds dating back to the Neolithic period. How big is the cave? The system measures about 200 meters in length and reaches almost 60 meters in depth, forming a single wide, descending gallery. Is there always ice inside? The ice formations are most visible in winter and early spring, when dripping water freezes in the consistently cold air trapped deep inside the cave. Is the cave ecologically important? Yes — near the entrance grows the only confirmed Iberian Peninsula population of Timmia megapolitana, a critically endangered moss species.

Cueva de la Araña

Bicorp

Cueva de la Araña is a group of three rock shelters with prehistoric paintings in the municipality of Bicorp, in the Escalona river valley, in the province of Valencia. The site owes its fame to two scenes painted by the early inhabitants of the area: a goat hunt using bow and arrow, and a figure gathering honey from a wild bee colony — the oldest known depiction of bees and the earliest evidence of honey consumption by Homo sapiens. The paintings span a wide time range, from the Mesolithic to the early Bronze Age, and together with other Levantine rock art sites in eastern Spain were inscribed on the UNESCO World Heritage List in 1998. What will you see at Cueva de la Araña? The star attraction is the scene of a human figure climbing (or descending) along ropes down a rock face toward a beehive, with insects painted around the opening. It is one of the most recognizable images in all of Levantine rock art — reproductions of this scene have made their way into history textbooks and publications on the origins of beekeeping worldwide. The second key motif is the ibex hunt, showing archers drawing their bows in dynamic poses. The paintings are small and require a careful eye — the ochre pigments on the pale limestone background have survived remarkably well, despite being exposed to the elements for thousands of years. Beyond the art itself, the setting adds to the experience: the shelters sit in a gorge above the Escalona river, in a landscape typical of inland Valencia — dry hills, Mediterranean scrub, and a quiet that is hard to find closer to the coast. How do you get there and what does a visit involve? Bicorp lies inland, roughly 80 km from Valencia city, in an area without heavy tourist infrastructure — getting there means driving. The rock shelters themselves are protected and access is restricted: visits run as guided tours organized by the Ecomuseo de Bicorp, typically lasting around three hours. The route combines the walk up to the shelters with a short explanation of the archaeological context and a walk through the surrounding terrain above the Escalona. Booking ahead is worthwhile, since tour spots are limited and independent entry into the shelters is not permitted, in order to protect the paintings. When should you visit? Spring and autumn are the best times to go, when temperatures in this part of Valencia are moderate and the approach trail isn't exposed to the full summer sun. In summer, the rocky, largely treeless terrain can make the three-hour tour tiring. Sturdy walking shoes, water, and sun protection are worth packing regardless of the season. Frequently asked questions Can you visit Cueva de la Araña without a guide? No — access to the rock shelters is restricted and only possible through guided tours run by the Ecomuseo de Bicorp, which protects the paintings from damage. What exactly do the paintings show? Two main scenes: an ibex hunt with bow and arrow, and a person gathering honey from a wild bee colony — the oldest known depiction of this activity anywhere in the world. How long is the tour and how demanding is it? The standard guided tour lasts about three hours and includes walking across rocky terrain above the Escalona river — it calls for a basic level of fitness and proper footwear. Why is this site on the UNESCO World Heritage List? Cueva de la Araña forms part of a broader UNESCO inscription covering Mediterranean Basin rock art on the Iberian Peninsula, recognized in 1998 as an exceptional record of prehistoric artistic expression.

Cova des Fum

Formentera

Cova des Fum is a karst cave carved into the cliffs of La Mola on Formentera, tucked into one of the island's most remote corners. It sits on the northwestern slope of the cliffs, between Punta de sa Palmera and Punta del Torrent des Gat, roughly 75 meters above sea level. Archaeologically, it is considered the most significant cave on the entire island, though its difficult access means few visitors ever reach it. How was the cave formed? Cova des Fum is a karst cavity hollowed out of the limestone mass that forms the La Mola plateau. Inside, a system of galleries shows clear signs of erosion and sediment deposits built up over long periods. The entrance is partly obstructed by blocks that collapsed from the roof, and traces of three ancient defensive walls survive between them. The main chamber has a floor covered by a layer of sand of marine and dune origin, its thickness varying from spot to spot. What has been found inside? Excavations at Cova des Fum have produced some of Formentera's most significant archaeological finds. Fragments of bell-beaker pottery from the Eneolithic period turned up here — a rare find in the Balearics outside Mallorca. Bronze Age material includes a barbed arrowhead, bone points, and a fragment of an archer's wrist guard, alongside plain ceramic bowls from several prehistoric periods. Human remains were also recovered from the inner chambers, pointing to the cave's use as a burial site during the Bronze Age. Medieval Andalusian ceramics dating from the 10th to 13th centuries — jugs, glazed vessels, and oil lamps — show that the cave continued to be used by the island's Muslim inhabitants, likely as a fortified refuge, a use supported by the remains of defensive walls near the entrance. Where does the name and the smoke legend come from? "Cova des Fum" translates literally as "Cave of Smoke." A local legend attached to the name tells of a clash in the year 1108, when the Norwegian prince Sigurd, on his way to the Holy Land, is said to have fought Muslim defenders holed up in the cave and defeated them by smoking them out of their hiding place. The episode belongs to legend rather than documented history, but it captures the cave's real role as a defensive stronghold during the period of Andalusian rule over the Pitiusic Islands. Can you actually get there? Reaching Cova des Fum is genuinely difficult, which is the main reason it remains obscure even among visitors who know Formentera well. From land, a steep, winding path drops down the cliff face to the entrance, demanding good physical condition and careful footing the whole way. Approaching from the sea is considered just as demanding. Given the terrain, this is a destination better suited to visitors prepared for rugged cliffside hiking than to casual sightseers. Frequently Asked Questions Is Cova des Fum easy to reach? No. There is no marked trail, and reaching it means descending a steep, winding path down the La Mola cliffs, or making an equally difficult approach from the sea. What makes this cave archaeologically important? Its finds span Eneolithic bell-beaker pottery, Bronze Age tools and weapons, and medieval Andalusian ceramics, making it the most significant archaeological cave site on Formentera. Where does the cave's name come from? From the Catalan word "fum" (smoke), tied to a local legend about a 1108 clash in which smoke is said to have decided the outcome. Were burials found inside the cave? Yes, human remains recovered from the inner chambers indicate the cave was used as a burial site during the Bronze Age.

Cova des Càrritx

Ciutadella

Cova des Càrritx is an archaeological cave set on the western slope of the Algendar ravine, within the municipality of Ciutadella de Menorca on the island of Menorca. Discovered in 1995 by local cavers Pedro Arnau and Josep Marquez, it has become one of the most significant prehistoric sites in the Balearic Islands, prized for its well-preserved traces of ritual and funerary use spanning thousands of years. What does the cave look like inside? The cave extends for roughly 170 metres and is made up of seven interconnected chambers linked by narrow passages. Its interior is decorated with numerous stalactites and stalagmites, and the entrance was once sealed by a cyclopean wall — a construction of large, roughly hewn stone blocks typical of the island's prehistoric architecture. What traces of the past have been found here? Research has shown that the cave saw human activity across several distinct periods: the late Chalcolithic (end of the 3rd millennium BC), the Bronze Age (2nd millennium BC), and again during the Almohad period in the 13th century AD. The Bronze Age phase carries the greatest significance, when the cave served as a site for rituals and burials. In one of its more hidden chambers, numbered 5, archaeologists uncovered an unusual deposit: wooden containers and horns filled with locks of human hair. That very deposit later became the basis for a landmark scientific study. Why is Cova des Càrritx internationally known? Chemical analysis of the preserved hair allowed researchers to detect psychoactive substances consumed by Menorca's inhabitants roughly 3,000 years ago. The findings are considered the first direct evidence of drug consumption in prehistoric Europe, turning Cova des Càrritx into a reference point in archaeology and in the study of prehistoric ritual practices. Who should visit this site? Cova des Càrritx appeals mainly to visitors interested in archaeology, prehistory, and Menorca's natural heritage. Given the scientific importance of the site and the sensitivity of its finds — including human remains — access can be restricted or may require prior arrangement; this is not a typical open-access tourist cave but a site of considerable research value. The surrounding Algendar ravine itself makes for a worthwhile stop when exploring the island's western countryside. Frequently Asked Questions Where is Cova des Càrritx located? The cave lies on the western slope of the Algendar ravine, within the municipality of Ciutadella de Menorca, in the western part of the island. When was the cave discovered? Cova des Càrritx was discovered in 1995, when cavers Pedro Arnau and Josep Marquez located a small entrance opening on the ravine's slope. What makes Cova des Càrritx different from other caves on Menorca? It stands out for its multiple phases of use dating back to the Chalcolithic and Bronze Age, and for the hair deposit that provided some of the earliest evidence of drug consumption in prehistoric Europe. Can visitors explore the cave on their own? Because it is a sensitive archaeological site containing delicate finds, access can be limited — it's worth checking current visiting conditions locally or through a guide before planning a visit.

Cueva de Chaves

Casbas de Huesca/Casbas de Uesca

Cueva de Chaves is an archaeological cave near Casbas de Huesca (Casbas de Uesca), in the province of Huesca, Aragón, at the foot of the Sierra de Guara, close to the small village of Bastarás. It ranks among the most significant Neolithic sites on the Iberian Peninsula, second in importance only to the Cova de l'Or in Alicante, according to specialists in Iberian prehistory. Why does this cave matter to archaeologists? Excavations that began in 1975 uncovered nearly 15,000 years of intermittent human presence, spanning the Upper Solutrean, the Upper and Final Magdalenian, and later the Neolithic. It's the Neolithic layer that draws the most attention: material dated to roughly 7,500 years ago documents some of the earliest farming and herding communities on the Iberian Peninsula, capturing the shift from hunting and gathering toward settled agricultural life. The site also forms part of the Mediterranean Basin rock art ensemble on the Iberian Peninsula, inscribed on the UNESCO World Heritage List in 1998. What happened to the cave in 2007? The site's history took a dark turn in 2007, when the landowner allowed heavy machinery onto the property, causing damage that turned part of the cave into a watering trough for livestock. At that point archaeologists had studied only around 10 percent of the deposit; much of the Neolithic material was destroyed or dumped into a nearby ravine, leaving mainly Palaeolithic remains intact. The case ended up in the courts, and Aragón's heritage authorities spent years pursuing legal action to restore access to a site that had been largely off-limits due to private ownership disputes. Can visitors go inside today? Yes. After roughly two decades of restricted access, Cueva de Chaves has reopened to the public through organized guided visits led by archaeologists on a recurring basis. Several dozen visitors have already toured the cave since access resumed, making it a rare chance to see a site that was closed to the wider public for so long, and that now plays a role in explaining the prehistory of the Huesca region to visitors. Where can I see finds from the cave? Some of the objects recovered from Cueva de Chaves, including a ceramic vessel, are held at the Museo de Huesca in the provincial capital. The cave itself sits within the limestone landscape of the Sierra de Guara, an area known for its gorges and canyons, which makes Casbas de Huesca a good base for combining prehistoric heritage with the natural scenery of the Pre-Pyrenees. Frequently Asked Questions Where exactly is Cueva de Chaves located? In the municipality of Casbas de Huesca, in the province of Huesca, Aragón, near the village of Bastarás, at the foot of the Sierra de Guara. Why is the site considered so important? It preserves nearly 15,000 years of occupation, and its Neolithic layer, dated to about 7,500 years ago, is among the earliest evidence of farming and herding communities on the Iberian Peninsula, ranking second only to Cova de l'Or in overall significance. What happened to the cave in 2007? The landowner allowed excavation works that partially destroyed the deposit, turning it into a livestock watering point; only about 10 percent of the site had been studied by then. Is it possible to visit Cueva de Chaves now? Yes, guided visits accompanied by archaeologists have resumed after years of restricted access, though visiting arrangements remain regulated and worth checking in advance.

Cueva de Montesinos

Ossa de Montiel

Cueva de Montesinos is a limestone cave near Ossa de Montiel, in the province of Albacete, in the region of Castile-La Mancha, Spain. Its fame reaches well beyond speleology circles — this cave is the setting for one of the most debated episodes in Spanish literature, making it a required stop for anyone tracing the footsteps of Cervantes' most famous character. What is the cave's connection to Don Quixote? In Part Two of Cervantes' "Don Quixote," the knight has himself lowered by rope into the depths of this cave, where he falls asleep and experiences a vivid, fantastical vision of an enchanted underground world. The episode is famous precisely because Cervantes never resolves whether Don Quixote truly dreamed the vision or actually lived it — a deliberate ambiguity that has kept scholars and readers debating for centuries. For fans of the novel, standing at the mouth of the real cave that inspired this passage adds a tangible layer to one of literature's most imaginative scenes. What can be found inside the cave? At the lowest point of the cave lies a small lake, fed by rainwater that filters down through the rock. Hydrological studies have traced an underground connection between this lake and the Lagunas de Ruidera, the well-known chain of natural lakes nearby. That link explains why water levels inside the cave respond to broader hydrological changes across the area, and it makes the site a notable example of the karst formations characteristic of this part of Spain. Where is the cave located, and what's the surrounding landscape like? Cueva de Montesinos sits close to the Lagunas de Ruidera Natural Park, a protected area famous for its cascading turquoise lakes separated by natural travertine barriers. The surrounding countryside is rugged and rural, with dry, stony hills giving way to green pockets around the water. That contrast between the harsh plains of La Mancha and the vivid color of the lakes is a large part of what draws visitors here — some chasing literary history, others simply the scenery. What should travelers know before visiting? Because the cave sits within an ecologically sensitive karst area connected to the Lagunas de Ruidera water system, access inside is often managed to protect the site and the water quality it shares with the surrounding lakes. It's worth building a visit around the wider Ruidera area, pairing the Cervantes connection with walks along the lake trails nearby. The cave rewards both literature enthusiasts retracing Don Quixote's steps and travelers with an interest in karst geology and the quieter landscapes of central Spain. Frequently Asked Questions Is Cueva de Montesinos a real place or just a fictional setting? It's a real cave in the municipality of Ossa de Montiel — Cervantes used an existing geographical location as the backdrop for Don Quixote's fictional adventure. How is the cave connected to the Lagunas de Ruidera? Studies have shown an underground water link between the small lake inside the cave and the Lagunas de Ruidera lake system, tying the cave into the same hydrological network. Is it worth combining a visit to the cave with the rest of the area? Yes — its proximity to the Lagunas de Ruidera Natural Park makes it easy to pair with a longer visit that combines the literary history with the natural lake trails nearby. Who is this destination best suited for? Primarily readers and fans of Cervantes' work, though anyone interested in karst landscapes and the rural scenery of La Mancha will find it worthwhile too.

Ursalto-ko koba II

Arruazu

Ursalto-ko koba II is a cave in the municipality of Arruazu, in Navarre, in the Basque Country of Spain. It sits in the Aralar mountain range, near the Uztoki farm buildings, along the road that runs from Lakuntza toward the Aralar forest house. It is one of two neighboring caves sharing the Ursalto name — its counterpart, Ursalto-ko koba I, lies in the same spot nearby. What does Ursalto-ko koba II look like? The cave has a small entrance, and inside visitors find numerous broken stalactites, evidence of the natural karst processes that have shaped the site over thousands of years. Navarre, and the Aralar range in particular, is rich in karst terrain: the limestone bedrock has produced countless caves, sinkholes and underground passages across the area, and Ursalto-ko koba II is one of the smaller but recognizable examples of this kind of formation in the region. How do you get to the cave? Ursalto-ko koba II lies close to the Uztoki farm buildings, along the route connecting the village of Lakuntza with the forest house higher up in the Aralar range. This stretch is a popular hiking corridor — trails heading from Lakuntza toward Aralar pass near the cave, and the surrounding area also holds other landmarks of scenic and archaeological interest, including a nearby dolmen. For anyone walking the broader route through the area, the cave makes for a natural stop between Lakuntza and the higher ground of Aralar. What should you know before visiting? The cave is a natural, undeveloped site with no lighting or marked visitor paths, so anyone planning to go inside should bring their own light source and suitable footwear. The surrounding terrain is mountainous and damp, typical of the Aralar landscape, so visitors should be prepared for the changeable weather conditions common to this part of the Basque mountains. Why visit the area around Arruazu? Arruazu is a small village at the foot of the Aralar range, one of Navarre's most recognizable mountain areas. The region combines striking natural features — extensive karst landscapes, beech forests and upland pastures — with cultural heritage that includes traces of shepherding and megalithic settlement. Small caves like Ursalto-ko koba II are part of this broader landscape mosaic, one that draws hikers, cavers and nature enthusiasts alike. Frequently Asked Questions Is Ursalto-ko koba II set up for visitors? No, it is a natural site with no tourist infrastructure — there is no lighting, handrails or marked routes, so entering requires your own equipment and caution. How do you reach the cave from Lakuntza? The cave lies along the route from Lakuntza toward the forest house in the Aralar range, near the Uztoki farm buildings — the most practical way there is on foot, following the trail in that direction. What is the difference between Ursalto-ko koba II and Ursalto-ko koba I? They are two separate caves located close together in the same spot near Uztoki — Ursalto-ko koba II is one half of that pair. What can you see inside the cave? Inside are numerous broken stalactites, a sign of the natural karst processes that have shaped this small cave over the centuries.

Cueva de la Cocina

Dos Aguas

Cueva de la Cocina is an archaeological cave in the municipality of Dos Aguas, in the province of Valencia. It sits on the right bank of the Cinto Ventanas ravine, at roughly 400 meters of altitude, and ranks among the most important Epipaleolithic and Mesolithic sites on the Iberian Peninsula. Where is Cueva de la Cocina located? The cave lies within the Barranco de Cinto Ventanas gorge, close to another rock-art site, the Cinto Ventana shelter. The interior covers about 300 square meters, reaching a maximum width of 15 meters and a depth of 20 meters, while the entrance mouth is nearly 15 meters wide and 3 meters high. These generous proportions made the cave genuinely livable, which is likely why groups kept returning to it across thousands of years. Why does this site matter archaeologically? The site was identified in 1940, with the first excavations carried out between 1941 and 1943 and again in 1945; more recent fieldwork, including a campaign in 2016, continues to add new data. Cueva de la Cocina is best known for its rich assemblage of geometric microliths — small stone tools with distinctive geometric shapes. The stratigraphic sequence recovered here became a reference model for dating the Recent Mesolithic along the entire Mediterranean coast of Iberia; archaeologists now refer directly to the "Cocina facies" when comparing other sites to this one. Occupation layers stretch back to the 9th millennium BC and span the Epipaleolithic through the Mesolithic and into the advanced Neolithic, possibly reaching the early Chalcolithic. That represents an almost uninterrupted, multi-millennial use of the same shelter by successive groups of hunter-gatherers and, later, early farming communities. What will you see in and around the cave? The south wall of the cave preserves rock paintings attributed to Levantine Art, dated to approximately 10,000–6,500 years ago. The scientifically crucial detail is that the painted panel is covered by archaeological layers containing no pottery — one of the few direct pieces of evidence proving that Levantine paintings were made by Epipaleolithic hunter-gatherer groups rather than in a later period. The paintings were studied in the late 1980s by researchers Anna Alonso and Alexandre Grimal Navarro. Levantine Rock Art from the Valencia region, including the frieze at Cueva de la Cocina, was inscribed on the UNESCO World Heritage List in 1998. Nearby, the Cinto Ventana shelter holds additional paintings, and a walking route through the gorge links both sites for visitors interested in the full rock-art itinerary. How do you get to Cueva de la Cocina? Access is on foot, following the Barranco de Cinto Ventanas gorge near Dos Aguas; the marked trail connecting the cave, its paintings, and the Cinto Ventana shelter is popular with hikers and archaeology-focused travelers. Because the gorge has rocky, occasionally steep sections, sturdy footwear and enough daylight for the return leg are worth planning for. When is the best time to visit? Spring and autumn offer the most comfortable conditions, with moderate temperatures in the gorge and rock surfaces that aren't overheated by direct sun. Summer heat in this inland part of Valencia province can be intense, particularly around midday. Frequently asked questions Can visitors enter the cave interior? Access to the interior is sometimes restricted to protect the archaeological site — check current visiting rules with the Dos Aguas local authorities before planning a trip. What makes Cueva de la Cocina different from other rock-art caves in the region? Its defining feature is the pottery-free archaeological layers sealing the painted panel, which offer rare, direct proof of the Epipaleolithic origin of the Levantine art found here. Do you need a guide to visit the area? It isn't mandatory, but given the scientific value and sensitivity of the site, joining a guided visit with a local expert makes it much easier to understand the archaeological context. How long does the route to Cinto Ventana take? The trail linking the cave with the Cinto Ventana shelter is a multi-hour hike, depending on pace and how many stops you make at the painted panels along the way.

Cueva Grande o de los Corrales

Castro-Urdiales

Cueva Grande o de los Corrales is a cave holding Paleolithic art in Otañes, a parish of the municipality of Castro-Urdiales in Cantabria, northern Spain. Unremarkable from the outside, its interior preserves traces of human presence going back tens of thousands of years, placing it among the notable rock-art sites of the region. Where is it and how to get there? The cave lies in Los Corrales, a small settlement within Otañes — one of the parishes of Castro-Urdiales, in eastern Cantabria near the border with the Basque Country. Castro-Urdiales itself, best known for its Gothic church of Santa María and its harbour old town, sits several kilometres from the cave, and the most practical way to reach Otañes is by car, through a rural landscape of rolling hills typical of inland Cantabria. Before setting out, it is worth checking with the local tourist office, since access to the cave's interior is restricted and controlled to protect the images inside. What does the cave contain? Cueva Grande was discovered in 1970. Even the vestibule, the most accessible part of the cave, yielded a rich set of finds — animal bones, flint tools and pottery fragments — pointing to repeated use of the site by different groups over time. The vestibule splits into two galleries: the left one leads to a small, circular chamber, while the right one connects to a further section of the cave holding its most valuable images. It is there that two carefully executed engravings appear, depicting a deer and a goat, dated to the Magdalenian period, roughly between 16,500 and 14,000 years ago. Deeper inside, black paintings belonging to the so-called Schematic-Abstract cycle are also visible, along with fine engravings showing animals facing one another. This mix of techniques and motifs — from realistic engravings to abstract compositions — makes Cueva Grande a notable example of the long, layered use of caves by prehistoric communities along this stretch of the Cantabrian coast. Given its scientific value and the fragility of the images it preserves, the cave was listed as a Bien de Interés Cultural (Site of Cultural Interest) in 1998. This designation underlines the importance of the site for the study of Paleolithic art on the Cantabrian coast, alongside the region's more widely known cave-art locations. When to visit? Since Cueva Grande is primarily a restricted-access archaeological site, a visit is best planned in advance by contacting the local tourism office or the institutions responsible for protecting Cantabria's cultural heritage. For those interested in the surrounding area without entering the cave itself, spring and summer are the best times to explore Otañes and the nearby coastline, when the weather favours walking along the region's rural roads. Autumn and winter bring fewer visitors, though Cantabria's damp climate is worth keeping in mind year-round. Frequently asked questions What is Cueva Grande o de los Corrales? It is a cave in Otañes (Castro-Urdiales) containing Magdalenian-period engravings and paintings, including depictions of a deer and a goat dated to 16,500–14,000 years ago. When was the cave discovered? It was discovered in 1970, and excavation of its vestibule uncovered paleontological materials, flint tools and pottery fragments. Can visitors freely enter the cave? Access is restricted to protect the rock art inside — it is advisable to check visiting conditions with the local tourist information office beforehand. What protected status does the cave have? Since 1998, Cueva Grande has been listed as a Bien de Interés Cultural, confirming its importance to Cantabria's archaeological heritage.

Mendukilo cave

Larraun

Mendukilo Cave sits in the municipality of Larraun, in Spain's Navarre region, right next to the village of Astitz and just a few minutes from the town of Lekunberri, at the foot of the Aralar mountain range. It's one of the few caves in the area open to guided visits, known for the floating walkway that carries visitors through its underground chambers. How do you get to Mendukilo Cave? The cave lies in the Larraun valley, within the Sierra de Aralar, on land belonging to the council of Astitz. The nearest well-known reference point is Lekunberri, a few minutes away by car. The cave entrance serves as the meeting point for organized tours, and booking ahead is required since visits run only in guided groups. What will you see underground? The route covers roughly 540 metres and passes through three connected chambers, reaching more than 40 metres below the surface. Inside, visitors find rich mineral formations — stalactites, stalagmites, and flat, curtain-like draperies hanging from the ceiling. Dynamic lighting highlights the rock shapes and creates atmosphere without disturbing the cave's natural setting. The whole route runs along a raised floating walkway suspended above the cave floor, which keeps foot traffic from affecting the underground environment. What is the visit like? A visit lasts about 60 minutes and only happens in groups — a minimum of 5 and a maximum of 30 people — led by a local guide. Arrive at the entrance five minutes before your scheduled time. Bookings can be made by phone or through the cave's website. Footwear matters here: the walkway rules out high heels, so wear something flat and sturdy. For centuries the cave served local shepherds as a natural winter shelter for mountain livestock before it opened to the public on 22 July 2005. When should you visit, and what should you bring? Inside, the temperature holds steady at 8–9°C year-round regardless of the weather outside, so warm clothing is essential even in summer. Thanks to that constant temperature, the cave can be visited in any season, though it's worth checking the tour schedule in advance — group sizes are capped, and slots can fill up quickly on weekends and during holidays. Frequently asked questions Can I visit Mendukilo Cave on my own, without a guide? No. Visits run only in guided groups with a local guide, and you need to book in advance. How long is the visit and how long is the route? The visit takes about 60 minutes, covering a roughly 540-metre route through three chambers more than 40 metres underground. What's the temperature inside, and what should I wear? It stays cool year-round at 8–9°C, so bring warm clothing regardless of the season outside, along with flat, comfortable shoes. Since when has the cave been open to visitors? Mendukilo opened to the public on 22 July 2005, after centuries of use by locals as a natural shelter for mountain livestock.

Cueva del Cuco

Castro-Urdiales

Cueva del Cuco is a small cave in Castro-Urdiales, in the Urdiales district of Cantabria, holding a rare set of Palaeolithic rock engravings. Its entrance opens in a limestone cliff clearly visible from the town's bullring, making it an easy landmark to spot even for visitors who won't be going inside. Where is the cave located? Cueva del Cuco sits within the town of Castro-Urdiales, in its eastern Urdiales district. The mouth of the cave is set into a rock face right at street level, directly across from the local bullring — the simplest reference point for finding it. The surroundings are part of the town's built-up coastal stretch, so reaching the site doesn't involve any hiking. What is inside the cave? Past a small vestibule, a narrow, largely straight passage runs for around 100 metres. Roughly halfway along it opens a small chamber, which holds most of the discovered engravings. Two techniques were used: fine incised lines depicting animal heads and hindquarters, and wide, deeply cut grooves, including one large, complete deer figure. In total, the engravings identified include three deer, two ibex, two horses, and two animals that remain unidentified. Why does the cave matter historically? The engravings have been attributed to the Upper Solutrean period, giving them an estimated age of around 17,500 years. The cave was discovered in 1966, and its rock art was studied and published in 1968 by archaeologist Miguel Ángel García Guinea. Given its scientific value, the site was granted Bien de Interés Cultural status — Spain's cultural heritage protection category — in 1996. Can visitors go inside? The cave is currently closed to general public access. Visiting requires prior authorisation from Cantabria's regional culture and tourism authorities. In practice, this means there's no walk-in access — anyone wanting to see the interior needs to arrange the visit in advance through the relevant regional office. When is the best time to visit? Since entry depends on advance authorisation rather than opening hours, timing a visit is more about lead time with the regional administration than about weather or season. The cliff face and cave entrance itself, however, can be viewed from outside year-round — an easy stop while exploring the Urdiales district, for instance alongside a look at the nearby bullring. Frequently asked questions Can you enter Cueva del Cuco without booking ahead? No. The cave is closed to casual visits, and access has to be arranged in advance with Cantabria's regional culture and tourism authorities. What can be seen inside the cave? A narrow passage roughly 100 metres long leading to a small chamber with engravings of deer, ibex, horses, and a few unidentified animals, made using both fine incised lines and deeper carved grooves. How old are the cave's engravings? They date to the Upper Solutrean period, around 17,500 years old. Where exactly is the cave entrance? It opens in a limestone cliff in the Urdiales district of Castro-Urdiales, clearly visible from near the town's bullring.

Axlor cave

Dima

Axlor is a rock shelter and cave site in Dima, a small municipality in the Basque Country of northern Spain, recognized as one of the most important Middle Paleolithic sites on the entire Iberian Peninsula. The site sits on the slope of Mount Urrestei, in an area known as Kobalde-Indusi, right beside the natural rock arch called Jentilzubi, roughly fifteen meters above the ravine that drops toward the Indusi gorge. How was Axlor discovered? The shelter was found in 1932 by Basque ethnographer and prehistorian José Miguel de Barandiarán, while he was carrying out work at the nearby Baltzola cave. Systematic excavations at Axlor itself did not begin until 1967 and continued through 1974, spanning eight field seasons under his direction. Later research campaigns led by university teams have returned to the site in subsequent decades, uncovering further human and animal remains and refining the site's chronology. What has been found inside the cave? Axlor belongs to the Mousterian culture and is tied to Neanderthal occupation spanning roughly 100,000 to 50,000 years ago. The oldest deposits, labeled levels N through F, formed around 100,000 to 80,000 years ago, level D dates to about 70,000 years, and level B to roughly 50,000 years. Excavators recovered an extensive stone tool assemblage, including characteristic Mousterian sidescrapers made from flint transported from distant sources — evidence that Neanderthal groups moved across the landscape and maintained networks for exchanging raw materials. Researchers identified different knapping techniques through the sequence: a microLevallois approach in the lower levels and a distinctive Quina-type technique in level D. The site has also yielded more than a thousand bone tools, mostly retouchers made from long-bone shaft fragments, among the richest such collections in the region. One particularly striking find is a stone bearing an engraved X-shaped mark, dated to at least 45,000 years old — cited as evidence that Neanderthals were capable of symbolic, graphic behavior independent of the later arrival of modern humans in Europe. The cave has also produced human remains, including teeth and a skull parietal fragment, showing morphological features consistent with Neanderthals, while analysis of bird and carnivore bones from the Mousterian layers revealed cut marks left by human processing — documenting a diet that extended beyond typical large-game hunting. Why does Axlor matter to researchers? The site preserves one of the most complete Middle Paleolithic sequences in the North Atlantic region of the Iberian Peninsula. Studying its successive occupation layers has let scientists trace how Neanderthal groups organized their lives seasonally and adapted to a shifting Atlantic forest environment across tens of thousands of years, moving between warmer interglacial phases and colder glacial ones. How do you get to Axlor? Dima lies inland in Biscay, about 30 kilometers from Bilbao, tucked among the hills and valleys typical of the Basque interior. A car is the most practical way to reach the area — local roads lead toward Mount Urrestei, from where the shelter itself is reached on foot along a mountain trail. It's worth knowing that Axlor remains an active research site rather than a cave adapted for visitors, so access to the interior can be restricted; the main draw for travelers is the surrounding landscape and its deep historical context. What else is worth seeing nearby? The same municipality holds the Baltzola cave, where Barandiarán was excavating at the very moment he discovered Axlor, and which is known for its own Paleolithic cave art. Dima and its surrounding hills also make a good base for hiking through Biscay's green valleys, past pastures and beech woodland typical of the Basque countryside. When is the best time to visit? Spring and early autumn bring the most comfortable conditions, with moderate temperatures and dry, passable mountain trails. Summer can turn hot in direct sun, though the green valleys of Biscay temper the heat, while winter brings frequent rain and fog that can make the approach to the site more difficult. Frequently asked questions Can you tour Axlor cave like a typical show cave? No — it remains an active archaeological research site rather than a commercially developed cave, so access can be limited depending on ongoing or periodic fieldwork. Who lived in Axlor cave? Neanderthal groups associated with the Mousterian culture, occupying the site at different points between roughly 100,000 and 50,000 years ago. What is the most significant discovery from Axlor? Alongside its rich stone and bone tool collections, the stone engraved with an X-shaped mark stands out, seen as evidence of symbolic behavior among Neanderthals. How do you get to Dima? The easiest way is by car from Bilbao, about 30 kilometers away — the drive typically takes under an hour depending on traffic and time of day.

Cueva de los Ángeles

Villamalea

Cueva de los Ángeles is a small cave located in the municipality of Villamalea, in the province of Albacete, in the region of Castile-La Mancha. It sits roughly 7 km northeast of the town center, amid the typical Manchuela landscape of limestone hills and dry valleys. What will you find here? The cave itself is modest in size, with a depth of around 7 meters. Its name comes from the rock formations inside, which locals have long described as resembling angelic faces — a detail passed down through generations that gave the spot both its poetic name and its place in local folklore. Cueva de los Ángeles isn't a cave in the grand, cavernous sense — it's better described as a small rock shelter tied to a seasonal watercourse. Water appears here mainly after rainfall, trickling through small streams that eventually feed into the wider drainage system flowing toward the Cabriel River, one of the region's key rivers and a natural boundary between Castile-La Mancha and Valencia. What's the history behind it? The presence of water at this spot had real practical value for the local community. In the past, gardeners and small farmers built homes nearby specifically to make use of this scarce resource — valuable in the dry Mediterranean climate typical of the area — for irrigating their plots. Traces of this activity, including small plots and remnants of old agricultural structures, can still be spotted around the cave today, even though intensive farming here is now largely a thing of the past. How do you get there, and when's the best time to visit? The easiest way to reach Cueva de los Ángeles is by car from Villamalea, heading northeast from the town center — the drive takes only a few minutes. The site also lies along the PR-AB 40 hiking trail, part of the marked Senderos de Castilla-La Mancha network, making it a convenient stop for anyone planning a day combining nature and light hiking. Spring and autumn are the best seasons to visit, when temperatures in the Manchuela region are mild and the trails are most comfortable to walk. Summers here can get very hot, which makes longer hikes during midday less appealing. Bring sturdy walking shoes, water, and a camera — the surrounding hills offer nice viewpoints over the valley. Who is this destination for? Cueva de los Ángeles suits travelers looking for quiet, uncrowded natural spots rather than large, dramatic show caves. It appeals especially to hikers, landscape photographers, and anyone curious about the region's agricultural history and traditions. Given its small scale, a visit typically takes anywhere from a few dozen minutes to an hour, unless you plan to extend your trip with a longer walk along the nearby trails. Frequently asked questions How far is Cueva de los Ángeles from Villamalea's town center? The cave lies about 7 km northeast of town, roughly a ten-minute drive. Is there an entrance fee? No, it's a natural, open-air site that can be visited free of charge at any time. Do you need any special equipment to see it? No — comfortable walking shoes for uneven terrain are enough. The cave is small and easily accessible from ground level, with no caving gear required. Are there other attractions nearby? Yes, the site sits along the PR-AB 40 hiking trail, so a visit here can easily be combined with a longer walk through the surrounding Manchuela countryside.

Cueva de las Güixas

Villanúa

Cueva de las Güixas is a karst cave in Villanúa, sitting at the foot of the Collarada massif (2,886 m) in the Aragonese Pyrenees. Its name comes from the Aragonese word "güixa," meaning witch — local oral tradition from the 15th to the 19th century told of witches gathering deep inside the cave for sabbaths. The cave itself was carved out through the dissolution of limestone during the Quaternary period, in the Würm glaciation, roughly 25,000 to 30,000 years ago. How do you get there? Villanúa sits in the Aragón valley, right on the N-330 road heading toward the Somport pass and the French border, close to Jaca. The cave entrance is in the village itself, and every visit starts at the Centro de Interpretación Subterránea (Underground Interpretation Centre) in Villanúa. What will you see inside? The visit opens with a multimedia display at the interpretation centre, explaining how the cave formed and outlining the geology of the Collarada massif. After that introduction, the group heads out on a roughly 400-metre circular route through the cave itself — always with a guide, since independent access is strictly forbidden. The cave is protected as a Site of Community Interest within the Natura 2000 network, which is why entry rules are so strict. The full visit, interpretation centre included, runs about one hour and fifteen minutes. Inside, the temperature stays cool and constant year-round, so bring warm clothing and comfortable, non-slip shoes. The site is equipped for visitors with reduced mobility. When to visit and how to book? The cave can be visited all year, but only in guided groups and with a prior reservation. Standard visiting slots run at 10:30, 12:00, 16:00 and 17:30, Tuesday through Sunday — the site is closed Mondays, except on public holidays. During high season, meaning summer and Easter week, more time slots are added. It's best to book ahead through the Villanúa tourist office (email: cuevas@villanua.net, phone +34 974 37 84 65) or the town's official tourism website. How much does it cost? A standard adult ticket costs €8, children aged 5 to 12 pay €6, and kids under 5 get in free. Prices can change, so it's worth confirming the current rate when you book. Background and legend Beyond the witch legend, the cave's history runs much deeper — the earliest traces of human presence in the area date back to the Eneolithic period, around 3,000 BC. According to legend, in a section known as the "Dolina" or "Chimenea" (chimney), witches would hold their sabbaths, using a natural opening in the rock that let them see the sky, the moon and the stars — elements considered essential to their rituals. Frequently asked questions Can you visit the cave on your own, without a guide? No. Because it's a protected site within the Natura 2000 network, entry is only allowed in guided groups with a prior reservation. How long does the visit take? The full visit, including the interpretation centre, lasts about one hour and fifteen minutes, and the route inside the cave itself covers around 400 metres. Is the cave accessible for visitors with disabilities? Yes, the site has facilities in place to accommodate visitors with reduced mobility. Where does the name "Güixas" come from? It comes from the Aragonese word for witch, tied to a centuries-old local legend about witches holding sabbaths deep inside the cave — though some researchers also link the name to "guixa," a type of legume once grown in the surrounding fields.

Armintxe Cave

Lekeitio

Armintxe Cave lies beneath the old town of Lekeitio, a fishing port on the Basque coast, tucked into the southern slope of Arbiatx hill. It holds one of the most important collections of Paleolithic rock art found anywhere in Europe this century — yet it's a site no visitor can actually step inside. How was the cave found? On 1 May 2016, eight cavers from the Basque speleology club ADES Espeleologia Elkartea squeezed through a narrow, hard-to-reach passage and broke into a chamber nobody had entered before. What they found on its walls — dozens of engraved animal figures — was quickly described by specialists as one of the most spectacular rock art discoveries ever made on the Iberian Peninsula. What do the engravings show? Around 50 figures cover the rock surface. Bison, ibex and horses dominate the panel — one horse engraving stretches nearly a metre and a half. The biggest surprise for archaeologists was a pair of engraved lions, a motif never before recorded in Basque rock art. Semicircles and linear marks accompany the animals, carved with a technique closely matching engravings from the French Pyrenees, hinting at contact between communities on both sides of what is now the border. The images date to between 12,000 and 14,500 years ago, placing them in the late Magdalenian period. Can you actually visit the cave? No — Armintxe stays closed to visitors to protect the fragile engravings from the humidity, carbon dioxide and light that foot traffic would bring in. Instead, Lekeitio's tourist office runs a free continuous video showing the cave's interior, and the Bizkaia regional government has produced a 3D digital reconstruction of the engraved chamber, one of nine Basque Paleolithic sites scanned this way. When's the best time to see more of it? Plan around early August, when Lekeitio holds Arkeologia Eguna (Archaeology Day): guided talks, children's workshops and virtual projections that let you "enter" the cave without putting the artwork at risk. Outside that event, the tourist office keeps Armintxe material on display year-round, and Lekeitio itself — with its harbour, old quarter and beaches — makes an easy base for exploring this stretch of the Bay of Biscay coastline. Frequently asked questions Can I go inside Armintxe Cave? No. The cave is closed to the public to protect the engravings; only researchers working on the site are allowed inside. How can I see the engravings if I can't enter? Lekeitio's tourist information office shows a video of the cave's interior year-round, and once a year, during Arkeologia Eguna, it adds 3D projections and themed workshops. Who discovered the cave, and when? Eight cavers from the ADES Espeleologia Elkartea club found it on 1 May 2016 while exploring a difficult passage beneath the town centre. What exactly is engraved on the walls? About 50 animal figures — mostly bison, ibex and horses — plus a pair of rare lion engravings, all dated to roughly 12,000–14,500 years ago.

Legarrea

Bertizarana

Legarrea is a natural sinkhole cave (locally called a "sima") in the municipality of Bertizarana, in northern Navarre, about 2 km southwest of the town hall, near the village of Legasa. It sits at the meeting point of the rugged Malerreka countryside and a difficult chapter of 20th-century history, making it both a hiking destination and a site of remembrance. How do you get to Legarrea? The usual starting point is the village of Legasa, roughly an hour's drive from Pamplona, or easily reached from Elizondo in the nearby Baztán valley. Parking is available near the village sports court, where the marked trail begins. The path first climbs along a dirt track past wooden firewood sheds, then rises steadily toward the Mokorro pass at 474 metres. From there it branches off toward the cave, sitting at around 488 metres above sea level. The full loop covers about 8.6 km and takes roughly 3.5 hours at an unhurried pace with stops, with a total elevation gain of around 378 metres from the trailhead at 125 metres. The route is well signposted and straightforward to follow — a single path leads up to the top, and the same path brings you back down. What will you see there? Sima de Legarrea is a natural limestone sinkhole, open to the sky, typical of this part of Navarre's karst landscape. For decades, locals used it informally as a dumping ground, and layers of discarded waste are still visible inside. Beyond its geology, though, the site carries heavy historical weight: according to archaeological research carried out by the Sociedad de Ciencias Aranzadi, the sinkhole was used during the Spanish Civil War as a burial site for victims of wartime violence, reportedly including a pregnant woman and several of her children. In 2016, the Government of Navarre's Historical Memory office funded a project to clear the site and search for human remains. Because of this, visitors are encouraged to approach the cave with respect, treating it as a memorial rather than just another stop on the trail. Past the cave, the trail continues up to Mokorro peak (506 m), where hikers are rewarded with wide views over the hills of Malerreka and toward the nearby town of Santesteban. In the wider Bertizarana area you'll also find the Bertiz Aventura adventure park, and the region hosts an annual local festival, Malerrekako Eguna, celebrating traditions of this corner of Navarre. When is the best time to visit? Given the moderate elevation and mountain terrain, spring and autumn are the most comfortable seasons, offering mild temperatures and clear visibility. In winter, the upper stretches near the Mokorro pass can turn icy or slippery after rain or snow, so sturdy footwear is essential. In summer, an early morning start is recommended to avoid the midday heat on the more exposed sections near the summit. Frequently asked questions Can you reach the Legarrea cave on foot without a guide? Yes. The marked trail from Legasa is open to the public and does not require a guide, though carrying a map or GPS app is useful, especially in poor visibility. How long does the full route take? The complete loop from Legasa, via the Mokorro pass, the Legarrea cave, and Mokorro peak, takes about 3.5 hours at a relaxed pace with rest and photo stops. Is it safe to explore the cave itself? Sima de Legarrea is a natural sinkhole, not a developed tourist attraction — there is no lighting or safety infrastructure inside. Most visitors view it from the trail's edge rather than descending into it. Why is this site historically significant? Due to events from the Spanish Civil War, the cave is recognised as a memorial site linked to wartime repression. Archaeological studies and a Government of Navarre project have worked to document and honour this history.
