Complexo Ons-O Grove

Sanxenxo

Complexo Ons-O Grove is one of the most ecologically valuable stretches of the Galician coastline — a Special Conservation Zone (ZEC) that spans the inner waters and coast of the southwestern Ría de Arousa, the Ons archipelago and its surrounding waters, and a section of the northern shore of the Ría de Pontevedra. The protected area stretches across seven municipalities — Bueu, Cambados, A Illa de Arousa, Meaño, O Grove, Ribadumia, and Sanxenxo — covering a combined 7,607 hectares. It's in Sanxenxo, one of the most popular resort towns on the Rías Baixas, that part of this complex lies, making it an easy destination for travelers already based there. How did this protected area come to be? The site's protection history goes back to 2004, when the Atlantic Biogeographic Commission of the Natura 2000 network designated Complexo Ons-O Grove a Site of Community Importance (LIC — Lugar de Importancia Comunitaria). That status was a stepping stone: in March 2014 the area was upgraded to full Special Conservation Zone (ZEC) status, bringing stricter legal protection and more rigorous management rules for the habitats and species found here. What wildlife lives here? The waters and shores of the complex serve as a refuge for two endangered sea turtle species: the loggerhead turtle (Caretta caretta) and the green turtle (Chelonia mydas), both of which appear here as migratory visitors rather than year-round residents. The area also protects the rare vascular plant Rumex rupestris, typically found clinging to the rocky cliffs of the Atlantic coastline. Bird colonies are just as significant a draw. The complex hosts spoonbills, easily recognized by their flat, spatula-shaped bills, along with spotted redshanks, curlews, and numerous other wading and water birds that rely on the shallow bays and islands for feeding and rest during migration. Marine mammals are regular visitors too — porpoises, dolphins, and bottlenose dolphins are commonly seen, especially in the calmer inlets of the Ría de Arousa and around the Ons archipelago. Why is this area worth visiting? The combination of islands, shallow bays, cliffs, and river mouths packed into a relatively compact area makes Complexo Ons-O Grove remarkably diverse for its size. For anyone interested in birdwatching, marine wildlife, or simply a quieter encounter with the nature of the Rías Baixas, its proximity is a strong reason to use Sanxenxo as a base. Keep in mind that, as a ZEC, the zone is subject to specific conservation rules — some activities, such as boating or access to particular zones, may be regulated or seasonally restricted. Frequently asked questions What's the difference between a ZEC and an ordinary nature park? A Zona Especial de Conservación is a formal designation under the EU's Natura 2000 network, granted to areas of particular importance for preserving habitats and species listed in the Habitats Directive. It carries specific monitoring and protection obligations that go beyond the earlier, provisional LIC status. Which municipalities does the protected area cover? Complexo Ons-O Grove spans seven municipalities: Bueu, Cambados, A Illa de Arousa, Meaño, O Grove, Ribadumia, and Sanxenxo. Can you see sea turtles in this area? Yes, though as migratory species their presence isn't guaranteed year-round — both loggerhead and green turtles appear seasonally in the complex's waters. How large is the protected area? The complex covers a total of 7,607 hectares, including marine waters, sections of coastline, and the Ons archipelago itself.

Betanzos-Mandeo

Paderne

Betanzos-Mandeo is a protected natural area in Galicia, Spain, covering the valleys of the Mandeo and Mendo rivers across several municipalities in the province of A Coruña, including Paderne. Designated as a Special Zone of Conservation (ZEC) under the Natura 2000 network, it safeguards one of the best-preserved stretches of riparian forest and wetland in the Rías Altas region. What defines the Betanzos-Mandeo area? At its core are the Mandeo and Mendo rivers, which cut through narrow valleys before opening into wetlands near the mouth of the Ría de Betanzos. Along their banks, native riparian forests of alder, willow and ash have survived largely intact, typical of the Atlantic and Cantabrian coast of the Iberian Peninsula. These gallery forests, together with the marsh vegetation found downstream, are what give the area its ecological significance. Why is this river system so ecologically important? The Mandeo is known for its clean waters and rich biodiversity. Species living in the river include Atlantic salmon, brown trout, and lamprey — a species considered endangered and highly sensitive to water quality and free-flowing river conditions. Their presence makes the Mandeo valley one of the more important ecological corridors in northwestern Spain, linking inland mountain areas with the Atlantic coast. How does Betanzos-Mandeo fit into the wider conservation landscape? The area is not an isolated reserve. In May 2013, UNESCO incorporated it into a much larger territory recognized as the "As Mariñas Coruñesas e Terras do Mandeo" Biosphere Reserve, spanning over 116,000 hectares across numerous municipalities in the A Coruña province. The Special Zone of Conservation itself covers around 1,020 hectares, stretching across the municipalities of Aranga, Bergondo, Betanzos, Coirós, Irixoa, Miño, Paderne and Oza-Cesuras. What should visitors know before exploring it? The area is popular with hikers and nature enthusiasts, with trails running alongside the rivers that allow close-up views of the riparian forest without disturbing the most sensitive habitats. Its proximity to the historic town of Betanzos, with its medieval old town and the well-known Ría de Betanzos, makes it easy to combine a visit here with cultural sightseeing in the region. Frequently asked questions Where exactly is Betanzos-Mandeo located? In the province of A Coruña, Galicia, along the valleys of the Mandeo and Mendo rivers, spanning the municipalities of Aranga, Bergondo, Betanzos, Coirós, Irixoa, Miño, Paderne and Oza-Cesuras. What protection status does the area have? It is a Special Zone of Conservation (ZEC) under Natura 2000, and since 2013 it has also been part of the UNESCO "As Mariñas Coruñesas e Terras do Mandeo" Biosphere Reserve. What wildlife can be found here? Atlantic salmon, brown trout and the endangered lamprey, along with the typical fauna and flora of Atlantic riparian forests. Can you go hiking in this area? Yes, there are trails running along the rivers that are popular with visitors interested in nature observation and the river valley landscape.

Ortigueira-Mera

Ortigueira

Ortigueira-Mera is an extensive protected natural area on the coast of Galicia, covering the mouth of the Mera river together with the waters of the Ría de Ortigueira and the neighbouring Ría de Ladrido. Spanning close to 3,900 hectares across the municipalities of Cariño, Cerdido, Ortigueira, Pontes de García Rodríguez and As Somozas in the province of A Coruña, in the far northwest of Spain, the site was granted Special Area of Conservation (ZEC) status within the Natura 2000 network in 2004, after having been listed as a Site of Community Importance (LIC) since 2001. What defines this landscape? At the heart of the area lies an estuary of nearly 3,000 hectares, where the Mera river and smaller watercourses weave a dense network of tidal channels. The constant rhythm of the tides has shaped one of the largest expanses of intertidal mudflats in all of Galicia. The scenery is completed by broad salt marshes, sandy-muddy tidal flats, and a well-developed dune system along the coast. Toward the open sea, the estuary is partly sheltered by the Island of San Vicente, while nearby mountains rising almost to the shoreline give the area its distinctive, contrasting character between water and highland. Why is this site so important for birds? Ortigueira-Mera ranks among the most important wintering and stopover sites for waterbirds and waders in Galicia. During the colder months, large numbers of ducks gather on the mudflats and shallow waters of the southern part of the ría, including wigeon, teal and pochard. Wintering waders recorded here include bar-tailed godwits, oystercatchers, curlews, redshanks and grey plovers. Estimates suggest that several thousand waterbirds can winter in the area in a single season, which is why the site also carries Special Protection Area (ZEPA) status for birds, under the name Ría de Ortigueira y Ladrido. What forms of protection cover the area? Given its outstanding ecological richness, Ortigueira-Mera is covered by several overlapping layers of legal protection: it is designated as a Natural Space (Espacio Natural), a Special Protection Area for birds (ZEPA), and a Site of Community Importance (LIC) within the EU's Natura 2000 network, ultimately consolidated into its current Special Area of Conservation (ZEC) status. This layered protection is intended to safeguard the estuary's ecosystems — wetlands, marshes and dunes alike — from the tourism, agricultural and urban pressures that have significantly altered other stretches of the Galician coastline. What can visitors expect to see here? For visitors, Ortigueira-Mera is above all a place for quiet nature observation: wide views over flat, tide-flooded plains, flocks of waterbirds moving at dawn and dusk, and a largely unspoiled, sparsely built-up coastline. The closeness of the mountains and the dominant presence of water mean the landscape shifts noticeably with the time of day and the state of the tide — at low tide, broad muddy flats are exposed, while at high tide the water reaches almost to the foot of the surrounding hills. Frequently asked questions Where exactly is Ortigueira-Mera located? In the province of A Coruña, in northwestern Spain (Galicia), encompassing the mouth of the Mera river and the adjoining Ría de Ortigueira and Ría de Ladrido. How is this site different from a typical beach or seaside resort? It is primarily a protected area — an estuary with marshes, mudflats and dunes — valued chiefly for its biodiversity, especially waterbirds, rather than for tourist infrastructure. What is the best time of year for birdwatching? The winter months, when thousands of wintering ducks and wading birds gather on the mudflats and shallow waters. What protection status does the area hold? Ortigueira-Mera is both a Special Area of Conservation (ZEC) within the Natura 2000 network and a Special Protection Area for birds (ZEPA), having previously been listed as an LIC.

Río Landro

Viveiro

Río Landro is a river in northwestern Spain, in the province of Lugo, flowing through the Galicia region toward the Bay of Biscay. It rises on the western and southwestern slopes of the Sierra del Gistral, in the parish of Viveiro (municipality of Muras), at an elevation of roughly 800 metres above sea level, and runs for approximately 37 kilometres in total. After its mountain stretch, the river gradually slows and forms a series of meanders — those near Landrove, about five kilometres from the mouth, are already influenced by the tides. The Landro eventually reaches the sea just past the bridges of Viveiro, opening into the Ría de Viveiro. Why is Río Landro ecologically important? The middle and lower course of the river, running through the municipalities of Ourol and Viveiro, is subject to constant tidal influence, which creates a mosaic of distinctive habitats — estuaries, salt marshes, alder riparian forests, oak groves, chestnut groves, and dry heathland. This habitat diversity is why the Río Landro area has been designated a Special Conservation Zone (ZEC) under the European Natura 2000 network. The Site of Community Importance (LIC) covers land around several municipalities, including Mañón, Ortigueira, Alfoz, Burela, Cervo, Muras, Ourol, O Valadouro, O Vicedo, Viveiro, and Xove. What species live along the river? Río Landro is considered one of the best salmon rivers in northern Galicia, still hosting a small but reproducing population of Atlantic salmon. The clean water quality also supports freshwater mussels, including a notably significant population of the freshwater pearl mussel — a species highly sensitive to water quality, whose presence signals a healthy river ecosystem. Together with its tributary, the Río Bravos, the Landro preserves good examples of riparian gallery forest, forming an important ecological corridor for numerous plant and animal species. What can visitors see along Río Landro in Viveiro? In the town of Viveiro itself, a riverside walking path (paseo fluvial) runs along the banks of the Landro and the adjacent Ría de Viveiro, starting near the Valdeflores convent. The walk offers views over the river and its estuary and gives easy access to areas of significant ecological value without leaving the town. It is a popular spot with both locals and visitors exploring this stretch of the Galician coast, known for its mild climate and scenic river-mouth views. Frequently asked questions How long is Río Landro? The river runs for about 37 kilometres, from its source in the Sierra del Gistral to its mouth at the Ría de Viveiro. Is Río Landro a protected area? Yes, the river valley is protected under the Natura 2000 network as a Special Conservation Zone (ZEC) due to its distinctive riverine and estuarine habitats. What wildlife lives in the river? The Landro is home to a small population of Atlantic salmon and to the freshwater pearl mussel, an indicator species of clean water. Where does the riverside walk in Viveiro start? The walking path along the river and its estuary begins near the Valdeflores convent in Viveiro.

ZEC Río Ouro

Foz

ZEC Río Ouro is a Natura 2000 protected area covering the middle and lower course of the Ouro River, which flows through the municipalities of Alfoz, O Valadouro, and Foz in the province of Lugo, Galicia. The river rises in the Serra do Xistral mountains and carves out a valley known locally as Val de Ouro before reaching the coast within Foz, where tidal influence shapes its final stretch into an estuary called Ría de Fazouro. Why is this stretch of river protected? The Ouro earned its status as a Zona de Especial Conservación (ZEC) thanks to its well-preserved riverside forest and the presence of rare and threatened species. Its waters and banks support conservation-priority populations, including Atlantic salmon and river mussels. Other species recorded here include lampreys, the Douro chub, Curtis's emerald dragonfly, and the Iberian desman — a small, elusive semi-aquatic mammal found only in parts of the Iberian Peninsula. What shapes the landscape of the Ouro valley? The river's middle and lower course runs through a well-preserved gallery forest dominated by alder, willow, buckthorn, ash, and hazel. This vegetation forms a natural ecological corridor, stabilizing the riverbanks against erosion and providing shelter for numerous animal species. Further downstream, where tides begin to influence the current, the landscape changes character: salt marshes covered in glasswort and rushes appear, leading into the Ría de Fazouro estuary. Where does the river meet the sea? The Ouro's mouth, known as Ría de Fazouro, is a small estuary almost entirely covered by salt marsh — a habitat type that is uncommon along the Galician coast. It opens onto the sandy beaches of Pampillosa and O Sarrido. Here, the river's fresh water mixes with seawater, creating conditions favorable to waterbirds and other species adapted to this transitional zone. Can you fish in the Río Ouro? The river also holds value as a fishing ground: its waters are managed as a coto salmonero, a designated area for salmon angling. The continued presence of Atlantic salmon in the Ouro is one of the reasons the area was included in the Natura 2000 network. How can you explore the Río Ouro valley? Marked walking routes follow the river, allowing visitors to experience both the forested valley section and the point where the river meets the sea. Walking along the riverbank offers a close view of the gallery forest, while the lower stretch reveals the transition from freshwater to marine environment within a relatively short distance. Frequently asked questions Where is ZEC Río Ouro located? In the province of Lugo, Galicia, spanning the municipalities of Alfoz, O Valadouro, and Foz. What does ZEC stand for? Zona de Especial Conservación, the Spanish term for a Special Area of Conservation under the Natura 2000 network. What species does this area protect? Among others, Atlantic salmon, river mussels, lampreys, the Douro chub, Curtis's emerald dragonfly, and the Iberian desman. Where does the river reach the sea? Within the municipality of Foz, forming the Ría de Fazouro estuary, which opens onto Pampillosa and O Sarrido beaches. Can you fish in the river? Yes, the lower stretch operates as a coto salmonero, a managed salmon fishing ground.

Cruzul-Agüeira

As Nogais

Cruzul-Agüeira is a protected natural area in the Os Ancares mountains, in the province of Lugo, Galicia, spread across the municipalities of As Nogais and Becerreá. Covering more than 618 hectares, it forms part of the European Natura 2000 network as a Special Conservation Area (ZEC). The site is notable for bringing together two plant worlds that rarely coexist, making it one of the more distinctive natural spots in this corner of Galicia. What makes this place special? The main draw of Cruzul-Agüeira is the coexistence of Mediterranean vegetation with species typical of the humid Atlantic climate. The area is home to a singular holm-oak forest, a tree usually associated with the drier, warmer south of Spain, growing alongside chestnut groves characteristic of green, rainy Galicia. Higher up, the two environments blend even further into a mixed forest that also includes native oaks. This mosaic of habitats packed into a relatively small area is the result of unusual geological and microclimatic conditions found in this part of Os Ancares. As Nogais and its natural surroundings As Nogais is a small municipality on a historic route linking Galicia with the rest of Spain, set among the mountainous, forested landscape typical of the Ancares region. Its proximity to Cruzul-Agüeira draws travelers looking for genuine contact with nature, away from crowded tourist routes — this remains a relatively little-known destination despite the ecological value confirmed by its Natura 2000 status. What to see on the ground In the lower part of the protected area, in a section known as Soto de Agüeira, visitors find a striking feature: limestone rock formations shaped by humidity and erosion over centuries. Locals call them "grobos," and the surrounding forest has earned a reputation as an almost magical woodland — dense, damp, covered in moss and lichen, with sunlight filtering through the canopy in a distinctive way. The spot is popular among nature photographers and hikers seeking a quieter alternative to the region's better-known trails. Frequently asked questions Where exactly is Cruzul-Agüeira located? The protected area lies in the Os Ancares mountains, in the province of Lugo, spanning the municipalities of As Nogais and Becerreá in northwestern Spain, within the region of Galicia. What protection status does the site hold? Cruzul-Agüeira is designated a Special Conservation Area (ZEC) under the European Natura 2000 network, meaning its ecosystems receive specific legal protection due to their unique ecological value. What can visitors expect to see? Highlights include the holm-oak forest (encinar), the chestnut-covered Soto de Agüeira, and the "grobos" rock formations in the lower valley, surrounded by a dense, damp, almost fairy-tale-like forest. Why do holm oaks and chestnut trees grow together here? This unusual pairing results from the area's particular geological and climatic conditions, where Mediterranean and Atlantic influences overlap, allowing species that rarely share the same ground in Galicia to grow side by side. Is the area suitable for hiking? Yes, the site is known locally as a hiking destination, particularly around Soto de Agüeira, where trails wind through the forest and past its distinctive rock formations.

Esteiro do Tambre

Noia

Esteiro do Tambre is the estuary where the Tambre River meets the Ría de Muros e Noia, one of the most valuable natural sites on the Galician coast. The protected area covers the final stretch of the river and the eastern half of the estuary, spread across the municipalities of Brión, Negreira, Outes, Noia and Porto do Son — the point where fresh river water mixes with the sea, forming broad muddy and sandy flats that are exposed and flooded by the tides. Why is this estuary protected? Esteiro do Tambre holds Special Conservation Zone (ZEC) status within the European Natura 2000 network, and it has been listed as a Site of Community Importance under the Habitats Directive since 2004. The protected area spans more than 15 km², over 1,500 hectares of which are intertidal muddy-sandy flats — a habitat that is essential for birds and invertebrates living in the tidal zone. What does the landscape look like? The estuary is shaped by reedbeds of common reed (Phragmites australis) and underwater meadows of dwarf eelgrass (Zostera noltii), while oak, ash and alder woodlands line the surrounding land. This mosaic of habitats, from salt marsh to riverside forest, lets the area work as a natural buffer between river and sea, as well as an ecological corridor for many species. Why bring binoculars here? Esteiro do Tambre is one of the more important birdwatching sites on the Galician coast. Several dozen pairs of the threatened western Iberian reed bunting nest in the reedbeds, and the sandy banks host breeding pairs of the rare Kentish plover. In winter, the southern bank of the estuary fills with migrating and wintering birds — great northern loons, black-throated loons, sanderlings and sandwich terns stop here to feed on the invertebrate-rich flats. For birdwatchers, the autumn and winter season tends to be the most rewarding, when species counts and numbers of individuals rise noticeably. How to visit the estuary? The area sits along the coastal route of the Camino de Santiago, making it an easily accessible stop for pilgrims and travelers making their way along the Ría de Muros e Noia. It's worth planning a visit around the tides — low tide exposes the wide flats where wading birds feed, while high tide covers most of the muddy bottom. A walk along the estuary shore, ideally early in the morning, offers the best chance to observe waterbirds in a quiet setting framed by deciduous woodland. Frequently asked questions Where exactly is Esteiro do Tambre located? It is the estuary of the Tambre River into the Ría de Muros e Noia, in the province of A Coruña, spanning the municipalities of Brión, Negreira, Outes, Noia and Porto do Son. What conservation status does the area have? It is a Special Conservation Zone (ZEC) within the Natura 2000 network, listed as a Site of Community Importance since 2004, covering more than 15 km². Which birds can be seen here? Threatened western Iberian reed buntings and rare Kentish plovers nest here, while great northern loons, black-throated loons, sanderlings and sandwich terns arrive in winter. Can it be reached on foot, for example from the Camino de Santiago? Yes, the area lies close to the coastal Camino de Santiago route, so it can be visited as part of a walk along the Ría de Muros e Noia. When is the best time to visit for birdwatching? The richest sightings come in autumn and winter, when migrating and wintering birds gather on the tidal flats.

Sil Canyon

Sober

Sil Canyon is a deep gorge carved by the Sil river in Galicia, in northwestern Spain. It spans the final 50 kilometers of the river's course before the Sil flows into the Minho — and it is precisely this stretch that is regarded as one of the most spectacular landscapes in all of Galicia. The canyon sits at approximately 42.40139° N, 7.41611° W. What is Sil Canyon? It is a gorge holding the status of a special area of conservation, meaning its natural value has been formally recognized and placed under legal protection within the European framework for nature conservation. Over a long span of time, the Sil river has cut into the region's bedrock, producing steep, deep slopes that give this section of Galicia a notably dramatic character compared with the gentler, rolling terrain typical of much of the rest of the region. Where exactly is it located? The canyon lies in Galicia, along the route the Sil river follows through its final 50 kilometers before joining the Minho. The Minho is one of the major rivers of the Iberian Peninsula, and the point where the Sil meets it serves as the natural reference point against which the canyon's course is described. Why is this stretch of the valley considered exceptional? Sources describe the landscape of Sil Canyon as the most spectacular in all of Galicia. That is a notable distinction, given that the wider region is itself known for varied, green terrain and numerous river valleys. What sets the Sil canyon apart is above all the scale and steepness of the slopes shaped by the river along this particular stretch of its course. Conservation status Formal recognition as a special area of conservation means the site's natural values — both geological (the canyon itself and the erosional processes that shaped it) and ecological (habitats tied to the river valley) — are subject to specific regulations intended to protect them from degradation. This kind of designation is granted to places with a natural character considered unique at a regional or national scale. Frequently asked questions Where is Sil Canyon located? In Galicia, in northwestern Spain, along the final 50 km of the Sil river's course before it joins the Minho river. Is it a natural site or a protected one? Both — the canyon holds the status of a special area of conservation, confirming its recognized natural value. What makes this canyon stand out within Galicia? It is regarded as one of the most spectacular landscapes in the entire region, distinguished by the scale and character of the terrain shaped by the Sil river. Which river formed the canyon? The Sil, a tributary of the Minho — one of the major rivers of the Iberian Peninsula. What are the canyon's coordinates? Approximately 42.40139° N, 7.41611° W.

Cíes Islands

Vigo

Illas Cíes is an archipelago in the Atlantic Ocean off the coast of Galicia, in northwestern Spain. The islands sit at the mouth of the Ría de Vigo, around 2.75 km from the mainland, and fall administratively under the city of Vigo, in the province of Pontevedra. Formerly known as Illas de Baiona, they are now regarded as one of the emblematic natural sites of the Galician coast. Where exactly are the Cíes Islands located? The archipelago stretches for 7.1 km, with a maximum width of 2 km. The islands close off the western entrance to the Ría de Vigo, separating it from the open Atlantic. Their coordinates place them at roughly 42.23°N, 8.9°W, within the Rías Baixas — the string of estuaries characteristic of southern Galicia's coastline. What protected status do the islands hold? The Cíes Islands were declared a Nature Reserve in 1980, a recognition of the archipelago's exceptional ecological value and a step toward shielding it from uncontrolled human activity. That protection was later expanded: in 2002 the islands were incorporated into the Atlantic Islands of Galicia National Park (Illas Atlánticas de Galicia), which brings together several archipelagos along the region's coast under a single conservation framework. As a result, the Cíes Islands are today managed as part of a broader network of protected areas intended to preserve their distinctive natural environment for future generations. Which province and region do the islands belong to? Administratively, the Cíes Islands form part of the city of Vigo, Galicia's largest urban center, even though the islands themselves lie some distance from its built-up area. They are formally located in the province of Pontevedra, within the autonomous community of Galicia in northwestern Spain. This position — straddling the open Atlantic and the sheltered waters of the Ría de Vigo — accounts for the archipelago's distinctive character, combining exposed oceanic coastline with the calmer conditions of the ria. How does the archipelago's former name differ from its current one? The islands were previously known as Illas de Baiona, a name referencing the nearby town of Baiona. Today, the name Illas Cíes has firmly replaced that older designation, both in official records and in everyday use among locals and visitors alike. Frequently asked questions How large is the Cíes Islands archipelago? The islands extend for 7.1 km, with a maximum width of 2 km. How far offshore are the islands located? The archipelago lies about 2.75 km from the coast of the Rías Baixas region. Which city administers the Cíes Islands? The islands fall under the city of Vigo, in the province of Pontevedra, Galicia. Since when have the islands been protected? They were declared a Nature Reserve in 1980 and became part of the Atlantic Islands of Galicia National Park in 2002. What was the archipelago previously called? It was formerly known as Illas de Baiona.

Complexo Intermareal Umia-O Grove

O Grove

Complexo Intermareal Umia-O Grove is one of the most significant protected natural areas on the Galician coast, stretching along the Ría de Arousa across several municipalities, including Cambados, O Grove, Sanxenxo, Meaño, Ribadumia and A Illa de Arousa. Covering more than 2,800 hectares in total, this wetland complex combines river mouths, dune systems, a coastal lagoon and tidal flats into a mosaic of habitats of exceptional value for waterbirds. Why is this area so ecologically important? The site carries an unusually dense stack of protection categories: it is a Fauna Refuge, a Special Protection Zone for Birds (ZEPA), a wetland of international importance under the Ramsar Convention, and part of both the Natura 2000 network and the Complexo Ons-O Grove Special Conservation Zone (ZEC). Few natural sites accumulate this many overlapping designations, which reflects how highly regional and international authorities rate its ecological value. What are the three parts of the complex made of? Complexo Intermareal Umia-O Grove is not a single continuous area but three spatially separate wetlands. The first is a wide inlet formed at the mouth of the Río Umia, closed off by the isthmus that carries the beach and dune system of A Lanzada. The second is the Bodeira lagoon, a freshwater coastal lagoon located on the western side of the O Grove peninsula. The third is Punta Carreirón, a headland at the southern tip of the Island of Arousa. Each of these three areas has a distinct habitat character, which increases the overall diversity of species found across the complex. What birds can be seen here? Waterbirds are the main reason this site holds such a high conservation status. In winter, more than 20,000 individual birds from around 200 different species have been recorded here. The extensive shallow waters, mudflats and lagoon provide excellent feeding grounds for migratory and wintering birds, while the rich salt-marsh and coastal vegetation supports nesting for many species throughout the year. What else stands out about the flora and fauna? Beyond its bird populations, the area is notable for its marsh and salt-tolerant plant communities, typical of estuaries along Galicia's Atlantic coast. The dune systems, such as the one at A Lanzada, create their own microclimate and habitat for species adapted to salty soil and strong coastal winds. The Bodeira lagoon, being a freshwater body sitting right next to the coastline, adds yet another distinct ecosystem type to an already varied complex. Frequently asked questions Where exactly is Complexo Intermareal Umia-O Grove located? It lies on the coast of the Ría de Arousa in Galicia, spanning the municipalities of Cambados, O Grove, Sanxenxo, Meaño, Ribadumia and A Illa de Arousa. How large is this protected area? The whole complex covers approximately 2,813 hectares, including both terrestrial and marine areas. Why does the site hold so many protection designations at once? Because of its outstanding importance for waterbirds and the diversity of its wetland habitats, it has been granted national protection (Fauna Refuge, ZEPA), European protection (Natura 2000, ZEC) and international protection (Ramsar Convention). What are the three main parts of the complex? They are the inlet at the mouth of the Río Umia with the A Lanzada dune system, the Bodeira lagoon, and the Punta Carreirón headland on the Island of Arousa. Is this a good place for birdwatching? Yes — in winter more than 20,000 birds from about 200 species can be observed here, making it one of the most important birdwatching sites on the Galician coast.

Costa da Mariña Occidental

Xove

ZEPA Costa da Mariña Occidental is a Special Protection Area for birds stretching along the Cantabrian coast of Lugo province in Galicia, covering territory within the municipalities of Cervo, Xove, Viveiro and O Vicedo. Spanning more than 2,100 hectares of coastline, it is regarded as one of the internationally significant reference points for seabird watching along the northern Spanish coast. What makes this coastline distinctive? The landscape is defined by steep cliffs carved by the Atlantic swell, granite outcrops riddled with caves and natural caverns, and small rocky islets rising just offshore. Vegetation clinging to the exposed slopes has adapted to constant wind and salt spray, and the area supports several plant species found only along this particular stretch of coast — a hallmark of maritime cliff ecosystems. Why was the area protected? The designation centers on the seabird colonies nesting along these cliffs and islets. Species recorded here include the yellow-legged gull and the crested cormorant, alongside more recent arrivals such as the sooty shearwater. A particularly notable milestone was the first recorded breeding of the northern gannet on the Iberian Peninsula within this reserve — a species previously associated mainly with the coasts of Britain and Ireland. Other species listed under EU bird directives that justified the site's protection include the peregrine falcon, the curlew sandpiper and the common tern. The area's protected status developed in stages: it was first listed as a Site of Community Importance in December 2004, later confirmed as a Special Area of Conservation in March 2014, in addition to its earlier designation as a Special Protection Area for Birds. What can visitors see on-site? Among the most recognizable landmarks are Cabo de Morás and the surroundings of Punta de A Roncadoira, in the municipality of Xove, both offering sweeping views over the cliff-lined shore and the open Atlantic. These spots are popular with nature photographers and birdwatchers alike, especially during migration seasons, when thousands of waterbirds and seabirds pass along this section of coast. Coastal footpaths allow visitors to reach viewpoints without entering the more sensitive cliff areas directly, helping keep breeding colonies undisturbed while still offering close access to the scenery. Frequently asked questions Where exactly is ZEPA Costa da Mariña Occidental located? It lies on the Cantabrian coast of Lugo province, Galicia, covering coastal land within the municipalities of Cervo, Xove, Viveiro and O Vicedo. Which birds can be seen here? Key species include the yellow-legged gull, crested cormorant, sooty shearwater, peregrine falcon, and — as a recent addition — a breeding colony of northern gannets. Is the area open to visitors? Yes, coastal paths and viewpoints run along the cliffs, though the nesting colonies themselves are protected and should not be disturbed. What protection status does the area hold? It is designated as a Special Protection Area for Birds (ZEPA) under the Natura 2000 network, and since 2014 also holds Special Area of Conservation (ZEC) status.

Costa Ártabra

Valdoviño

Costa Ártabra, also known as Golfo Ártabro, is a stretch of coastline in Galicia, in northwestern Spain. It lies between the Costa da Morte and the Rías Altas, forming a wide gulf typical of the deeply indented Galician shoreline. The area holds the status of a Special Area of Conservation, meaning its ecological value has been formally recognized and protected under the European system of protected natural sites. Where exactly is Costa Ártabra located? The gulf sits within the autonomous community of Galicia, in the northwestern corner of the Iberian Peninsula, at approximately 43.72°N, 7.95°W. To the west it borders the Costa da Morte, one of the most recognizable sections of the Galician coast, while to the east it transitions into the Rías Altas, a coastal stretch known for its deep, characteristic inlets called rías. How large is the gulf? Costa Ártabra reaches a maximum width of 5,800 metres. Its depth extends to 5,600 metres, measured at the point corresponding to the mouth of the River Mero at Santa Cristina beach. This river mouth serves as a key reference point for the whole area, effectively marking one of the boundaries used to define the gulf's extent. Which rivers flow into the gulf? Several rivers reach the sea within Golfo Ártabro. Besides the Mero, which ends its course at Santa Cristina beach, the rivers Mendo and Mandeo also have their mouths in the gulf. The presence of multiple river mouths within a relatively small area helps explain the richness of the coastal ecosystems here: where fresh water meets seawater, habitats favorable to biodiversity tend to form, which aligns with the protected status granted to this section of coastline. Why does this stretch of coast hold protected status? The designation of the gulf as a Special Area of Conservation indicates that the authorities responsible for nature protection in Spain and the European Union have recognized this area as valuable for the preservation of natural habitats. Such a designation is not given arbitrarily; it is typically backed by documentation confirming the presence of significant coastal and marine ecosystems whose conservation matters beyond the region itself. How does Costa Ártabra fit into the Galician coastline? The Galician coast is famous for its rías, long, narrow inlets formed when the sea flooded river valleys. Costa Ártabra, positioned between two other well-known coastal sections, the Costa da Morte and the Rías Altas, acts as a geographic link between these areas. Its location makes it a natural reference point when describing the transition from one type of coastal landscape to another along this part of Spain. Frequently asked questions What is Costa Ártabra? It is a gulf on the Galician coast, also called Golfo Ártabro, located between the Costa da Morte and the Rías Altas, and protected as a Special Area of Conservation. Which rivers empty into the gulf? The rivers Mero, Mendo and Mandeo flow into Golfo Ártabro, with the mouth of the Mero at Santa Cristina beach used as the reference point for measuring the gulf's depth. How big is the gulf? Its maximum width is 5,800 metres, and its depth measured at the Mero river mouth is 5,600 metres. Where exactly is it located? In northwestern Spain, in Galicia, at approximately 43.72°N, 7.95°W, between the Costa da Morte and the Rías Altas.

La Fuentona natural monument

Cabrejas del Pinar

La Fuentona is one of six natural monuments recognized in the region of Castile and León, straddling the border between the municipalities of Cabrejas del Pinar and Muriel de la Fuente in the province of Soria. The protected area covers 232 hectares of landscape shaped over millennia by karstic processes and the steady emergence of underground water. What is the "Ojo de La Fuentona"? At the heart of the monument lies a spring known as Ojo de La Fuentona, the "Eye of La Fuentona" — the point where water rises from one of the deepest and most remarkable aquifers on the Iberian Peninsula, the Sierra de Cabrejas aquifer. This spring is the birthplace of the Abión River, which carves a narrow, scenic canyon right from its very first stretch. How did this landscape form? The terrain is built from Cretaceous and Neocretaceous materials with a carbonate composition, formed in a clearly marine sedimentary environment. As a result, fossil shells are abundant throughout the rock surrounding the spring. The entire formation rests on karstic relief, and it is precisely these karstic processes that gave rise to the underground reservoir feeding the Ojo de La Fuentona. What plant and animal life can be found here? The dominant species in the landscape is the sabina albar, a juniper of considerable rarity and botanical importance, typical of the highlands around Soria. Along the canyon carved by the Abión River, a distinct riverside vegetation develops, creating a microclimate noticeably different from the drier surrounding terrain. This variety of habitats also supports a rich fauna tied to both the aquatic and rocky environments of the gorge. When and why was the area protected? The site's exceptional geological, hydrological and botanical values led to its designation as a Natural Monument in November 1998. Since then, La Fuentona has stood as one of six natural monuments officially recognized across the autonomous community of Castile and León, underlining its significance among the region's protected sites. Frequently Asked Questions Where exactly is La Fuentona located? The Monumento Natural La Fuentona lies across the municipalities of Cabrejas del Pinar and Muriel de la Fuente, in the province of Soria, Castile and León. Which river originates here? The Abión River rises from the Ojo de La Fuentona spring and immediately forms a deep, narrow canyon. Why is the water here so distinctive? The spring is fed by one of the deepest and most notable aquifers on the Iberian Peninsula, the Sierra de Cabrejas aquifer, shaped within karstic rock. What vegetation stands out in this area? The sabina albar, a rare and botanically significant juniper, is the defining species, growing alongside lush riverside vegetation along the canyon. Since when has the area been protected? It was declared a Natural Monument in November 1998 and is now one of six such sites in Castile and León.

Acebal de Garagüeta

Arévalo de la Sierra

Acebal de Garagüeta is a nature reserve in the municipality of Arévalo de la Sierra, in the northern part of Soria province, Castile and León. Covering 406 hectares on the southern slope of the Montes Claros range, it protects one of the most unusual natural features on the Iberian Peninsula — an extensive forest made up almost entirely of holly trees (Ilex aquifolium). What makes this forest so unusual? Holly typically grows as scattered individual trees or small clusters within the understory of other woodlands. In Garagüeta the pattern is reversed: holly dominates the landscape almost exclusively, forming a dense, dark-green canopy across the hillside. This kind of formation is exceptional on a European scale — Acebal de Garagüeta is considered the largest continuous holly forest on the Iberian Peninsula and in southern Europe as a whole. In certain sections, other shrubs and trees appear alongside the holly, adding to the area's overall biodiversity. What protected status does the reserve have? The Dehesa de Garagüeta forms part of the Natura 2000 network, and in 2008 the site was formally declared a Natural Reserve, becoming one of the protected natural spaces of Castile and León. This designation safeguards a rare forest ecosystem from development and excessive tourist pressure while still allowing for controlled, educational visits. What can visitors see on site? The starting point for exploring the reserve is the Casa del Acebal, an information center housed in a building that once served as the residence of local schoolteachers from Arévalo de la Sierra. The Casa del Parque functions as an educational hub, explaining to visitors the ecological importance of the holly forests found in these mountains — not only Acebal de Garagüeta itself, but also comparable formations nearby, such as the Dehesa de Oncala. It's a worthwhile stop before setting out on the trails, offering context on the history, flora, and fauna of the area. The forest itself is best experienced on foot: marked walking trails wind through its most representative sections. In spring and summer the holly trees form a dense, cool canopy overhead, while in winter their evergreen leaves stand out sharply against the often snow-covered surrounding peaks. Where is Acebal de Garagüeta and how do you get there? The reserve lies within the municipality of Arévalo de la Sierra, in the northern part of Soria province, on the southern flank of the Montes Claros range. This is a typically mountainous, sparsely populated area of inland Castile and León, dotted with small villages set among forests and pastureland. For travelers exploring Soria, it makes a natural stop combining nature-focused tourism with a look at the traditional architecture and rural life of the surrounding mountain villages. Frequently asked questions What is an "acebal"? It's the Spanish term for a forest dominated by holly — a species that rarely forms large, self-sufficient forest stands anywhere else. Can visitors explore the reserve on their own? Yes, the area is open to hikers, and the Casa del Parque provides information and materials to support independent visits. How large is the reserve? 406 hectares. Since when has the area been protected? It was formally declared a Natural Reserve in 2008, having already been included in the Natura 2000 network beforehand. Are there similar forests nearby? Yes, the nearby Dehesa de Oncala features a similar type of vegetation.

Sierra Norte de Guadarrama Natural Park

Alameda del Valle

Sierra Norte de Guadarrama Natural Park stretches along the northern slopes of the Sierra de Guadarrama mountain range, straddling the provinces of Segovia and Ávila in Castile and León. Its southern edge meets the neighboring Sierra de Guadarrama National Park on the Madrid side, and one of the municipalities included within this protected complex is Alameda del Valle — a village whose highest ground falls inside the national park, while the rest of the municipality sits within its peripheral protection zone. This location makes the area around Alameda del Valle a natural base for exploring both adjoining protected spaces. What defines the natural park's landscape? The park covers a range of mountain environments shaped by considerable differences in altitude and by slopes facing in every direction, which together produce a wide variety of habitats. The scenery is dominated by a rugged mountain range with rocky outcrops and extensive forests, chief among them stands of Scots pine covering much of the terrain. Lower down, the landscape gives way to oak woodland, holm-oak groves, and stretches of juniper scrub, adding further texture to the park's plant cover. What kind of wildlife and vegetation can be found here? The combination of altitude, exposure, and moisture across the park creates highly varied conditions, and this is reflected in a rich and often distinctive range of flora and fauna. Species adapted to a harsher mountain climate thrive in the upper reaches, while the mixed conifer and broadleaf forests lower down act as ecological corridors linking different sections of the range. This mosaic of habitats is one of the park's defining natural features. What can visitors do in the Sierra de Guadarrama? The mountainous terrain of the wider Sierra de Guadarrama draws visitors interested in almost any outdoor mountain pursuit. Hiking trails wind through the pine and oak forests, while the terrain also lends itself to climbing and, thanks to the thermal air currents rising along the ridgelines, to more specialized disciplines such as paragliding and hang gliding. The range's varied relief means both casual walkers and more experienced mountain sports enthusiasts find suitable routes and conditions. Why is Alameda del Valle a good base for visiting? Because it sits right where the national park and the Sierra Norte de Guadarrama natural park meet, Alameda del Valle offers a convenient starting point for travelers planning a longer stay in the mountains. A large part of the municipality lies within the protection zone surrounding the national park's core, putting visitors close to unspoiled nature while still having access to the small-scale tourist infrastructure typical of mountain villages in the region. Frequently asked questions Is Sierra Norte de Guadarrama the same as Sierra de Guadarrama National Park? No — they are two separate but adjoining protected areas. The Sierra Norte de Guadarrama natural park lies on the Castile and León side (Segovia and Ávila), while the Sierra de Guadarrama National Park covers mainly the Community of Madrid. Alameda del Valle borders both. What kind of landscape dominates the park? A mountainous terrain with extensive Scots pine forests on its slopes, complemented by oak woodland and juniper groves at lower elevations. Can visitors practice mountain sports in the area? Yes, the wider Sierra de Guadarrama offers a broad range of activities, from hiking to disciplines like paragliding that make use of the thermal air currents over the ridges. Is Alameda del Valle located inside the national park? The highest parts of the municipality fall within the national park, while the remainder lies in its surrounding protection zone.

Baza National Park

Baza

Sierra de Baza Natural Park is one of the larger protected areas in Granada province, stretching to the northeast of the town of Baza, right on the border with Almería province. It covers more than 53,000 hectares and forms part of the Cordillera Penibética, the mountain backbone running through southern Spain. The park has belonged to the Network of Protected Natural Areas of Andalusia (RENPA) since 1989, when it was designated as a natural park to safeguard its mountain environment. What does the landscape of Sierra de Baza look like? The park's terrain unfolds in distinct layers. The lower slopes are covered by extensive pine forests, which gradually give way to rockier, more barren ground as elevation increases. Above roughly 2,000 metres the scenery shifts to a high-mountain character, dominated by jagged limestone peaks that can carry snow through part of the winter. The range's highest point is Santa Bárbara, rising to 2,271 metres, offering sweeping views over the surrounding plateaus. The massif itself sits in an unusual setting: on one side it borders the arid Llanos del Marquesado plain, which separates it from the Sierra Nevada range, and on the other it meets the equally dry Hoya de Guadix basin. Sandwiched between these two parched landscapes, Sierra de Baza stands out as a surprisingly green, well-watered island of vegetation. What plants and animals live here? Around a hundred plant species have been recorded within the park. Holm oaks and gall oaks dominate alongside junipers, accompanied by classic Mediterranean scrubland vegetation, including berry-bearing shrubs and aromatic herbs. The park also preserves one of the region's last remaining stands of native Mediterranean pine forest. Wildlife is concentrated mainly in the rugged, hard-to-reach central section, home to birds of prey including the golden eagle and nine other raptor species, making Sierra de Baza one of Andalusia's more significant sites for observing birds of prey. Among mammals, visitors may encounter the badger, the wildcat, and the genet — a slender, cat-like carnivore typical of Mediterranean ecosystems. What traces of past human settlement remain in the park? Human presence in these mountains stretches back a very long way: rock paintings from the Palaeolithic period have been found on Monte Jabalcón, evidence that people have inhabited this area for thousands of years. In more recent history, the region went through periods of settlement followed by gradual depopulation. Scattered across the park today are abandoned villages and farmsteads such as Casas de Santa Olalla, Tablas, and Tesorero — now deserted, but still visible in the landscape as remnants of the mountain communities that once lived there. Frequently asked questions Where exactly is Sierra de Baza located? The park lies in the northeastern part of Granada province, adjacent to Almería province, in southern Spain. How large is the park? The protected area covers more than 53,000 hectares. What is the highest peak? Santa Bárbara, reaching 2,271 metres above sea level. Since when has the area been protected? It was designated a natural park in 1989 to protect the mountain environment. Are there traces of ancient civilizations in the park? Yes — Palaeolithic-era rock paintings survive on Monte Jabalcón, and abandoned villages and farmsteads can be found in various parts of the park.

Aztaparreta

Isaba / Izaba

Aztaparreta is one of the most valuable nature reserves in the Navarrese Pyrenees, tucked away in the Belagua valley within the municipality of Isaba, in the far northeastern corner of Navarre. It forms part of the larger Larra-Aztaparreta complex, protected as a Special Conservation Area (ZEC) under Decree 244/2011 of 14 December, and additionally covered by Special Protection Area for Birds status (ZEPA B-123). Aztaparreta itself, covering roughly 100 hectares, holds the status of an integral reserve — the strictest level of nature protection applied in Navarre, ruling out any form of economic exploitation. What makes this place special On the northern slope of Mount Txamantxoia, above the Rincón de Belagua, stretches a beech and fir forest of around 175 hectares, growing between 1,200 and 1,730 metres above sea level. In its lower section lies Aztaparreta — one of the last virgin beech-fir forests remaining anywhere in the Pyrenees, where the tree cover has never been commercially exploited. As a result, visitors can observe trees at every stage of their natural life cycle, from germination through maturity to the slow decomposition of fallen trunks, which in turn become habitat for insects, fungi and mosses. The forest's value has been recognised internationally: in 2017 the area was inscribed on the UNESCO World Heritage List as part of the transnational serial site "Ancient and Primeval Beech Forests of the Carpathians and Other Regions of Europe." This distinction places Aztaparreta among the continent's most precious, untouched forest ecosystems. The valley's history Although Aztaparreta is best known today for its untouched nature, the Belagua valley also has an economic history of its own. Archival photographs from the 1950s document a wooden dam built across the Aztaparreta stream — the remains of an old water reservoir that once served industrial or hydropower purposes in this remote corner of the Pyrenees. Little of that infrastructure survives today, and the valley has largely returned to a near-natural state. Wildlife and vegetation The ZEPA designation underlines the importance of Larra-Aztaparreta for mountain and forest birdlife, with species linked both to the open limestone terrain of the Larra massif and to the dense old-growth beech-fir woodland. The forest itself, thanks to the age of its trees and the abundance of deadwood, provides a habitat that is rare at European scale for organisms dependent on old, unaltered forest ecosystems. Getting there and what to expect Aztaparreta lies within the Belagua valley, reached from the town of Isaba — one of the gateways to the Roncal region in northeastern Navarre. Because of its status as an integral reserve, the area is not designed for intensive tourist use; the best way to experience it is to respect marked routes and conservation rules, treating a visit as an opportunity to observe a mountain landscape and a forest with an almost primeval structure. Frequently asked questions What is Aztaparreta? It is an integral nature reserve protecting a stretch of virgin beech-fir forest in the Belagua valley, municipality of Isaba, part of the larger Larra-Aztaparreta protected area. Why is Aztaparreta important? Because it preserves one of the last primeval beech-fir forests of the Pyrenees, inscribed on the UNESCO World Heritage List in 2017. What protection status does the area hold? It has been a Special Conservation Area (ZEC) since 2011 and is also a Special Protection Area for Birds (ZEPA B-123). Are there any traces of past human activity in the valley? Yes — including the remains of a wooden dam on the Aztaparreta stream, documented in photographs from the 1950s.

Hoces del Río Riaza Natural Park

Maderuelo

Hoces del Río Riaza Natural Park protects 5,145 hectares of river gorge in the northeastern corner of Segovia province, right up against the border with Burgos. Three villages sit within its boundaries — Maderuelo, Valdevacas de Montejo, and Montejo de la Vega de la Serrezuela — and it's from Maderuelo, perched above the reservoir, that most visitors set out to explore the canyon. What does the landscape of the park look like? The Riaza River runs from southeast to northwest, carving out three distinct stretches along the way. The first, between Maderuelo and the Linares del Arroyo dam, has gentler relief — the river has been dammed here since 1951, forming a long reservoir. Further on, over roughly 5.5 kilometers between the dam and the El Casuar stream, the river has cut deep into the limestone, creating a canyon up to 150 meters deep and 200 to 300 meters wide. These steep limestone cliffs are the heart of the park and its most striking feature. Why is this park important for birds? The park's greatest natural asset is its bird life, and above all its enormous griffon vulture colony — more than 150 breeding pairs nest on the ledges of the gorge, making it one of the largest colonies of the species in all of Europe. That alone makes the canyon a prime destination for raptor watching. Alongside the griffon vultures, the cracks and hollows of the cliffs shelter other species tied to this rocky habitat: the Egyptian vulture, the common kestrel, the crag martin, the red-billed chough, and the eagle owl, which hunts among the rock crevices at dusk. What should you see when visiting Maderuelo? The town of Maderuelo, picturesquely set on a promontory above the reservoir, is the natural starting point for exploring the canyon. Walking trails lead out from the area, letting visitors take in both the calmer, dammed stretch of the river and the wilder, rocky gorge further northwest. It's worth bringing binoculars — watching griffon vultures circle above the cliffs is one of the park's main draws, especially in the warmer months when the birds make the most of the thermal currents rising over the canyon. Frequently asked questions How large is Hoces del Río Riaza Natural Park? It covers 5,145 hectares in Segovia province, along the border with Burgos. What does the Riaza river canyon look like? A limestone canyon up to 150 meters deep and 200–300 meters wide, formed over roughly 5.5 km between the Linares del Arroyo dam and the El Casuar stream. What birds can you see in the park? Above all the griffon vulture (more than 150 breeding pairs, one of Europe's largest colonies), along with the Egyptian vulture, common kestrel, crag martin, red-billed chough, and eagle owl. Which villages lie within the park? Maderuelo, Valdevacas de Montejo, and Montejo de la Vega de la Serrezuela.

Las Quilamas

San Miguel de Valero

Las Quilamas is a protected natural area stretching north of the Sierra de Francia, in the southeastern part of the province of Salamanca, in the region of Castile and León. The territory forms part of the Sierras de Béjar y Francia Biosphere Reserve, recognized by UNESCO in 2006, and spans ten municipalities across roughly 11,100 hectares. The town of San Miguel de Valero sits right at the meeting point of two landscapes — the Sierra de las Quilamas on one side and the Sierra de Francia range on the other — making it a natural gateway for exploring the wider region. What kind of landscape does Quilamas offer? The terrain is classic medium-mountain country, shaped over millennia by the erosive action of the Alagón and Quilamas rivers along with the Palla stream. That slow carving created a succession of deep valleys and rugged, jagged ridgelines. The highest point in the area is Pico Cervero, rising to 1,465 meters above sea level. The underlying geology is distinctly siliceous, dominated by slates and quartzites typical of the whole Sierra de Francia and Quilamas range, giving the local rock outcrops their characteristic dark tone. Why is this area so ecologically valuable? The excellent conservation state of Quilamas' ecosystems has been one of the pillars supporting the prestige of the entire Sierras de Béjar-Francia Biosphere Reserve. Biodiversity here has been catalogued in remarkable detail: around 2,000 plant species have been recorded, of which 93 are endemic, and 8 of those exist nowhere else on Earth outside this reserve. Endemic species include the fish Cobitis vettonica and the lizard Iberolacerta martinezricae. Environmentally sensitive species such as otters also live here, a sign of how clean the local watercourses remain. What birds can be spotted here? The presence of black vultures, black storks, and golden eagles was decisive in the area being designated a Special Protection Area for Birds (ZEPA). Alongside its plant diversity, this rich birdlife was one of the key arguments for protecting the territory — birdwatchers visit the area hoping to catch sight of these large raptors and rare species circling above the valleys. What else is worth seeing around San Miguel de Valero? Thanks to its location, San Miguel de Valero also borders other areas of major touristic interest, including the Las Batuecas-Sierra de Francia Natural Area and the Las Batuecas Regional Game Reserve. This makes the surrounding region popular with visitors planning longer hiking routes that link several protected areas into a single trip. Frequently asked questions Where exactly is Las Quilamas located? In the southeastern part of the province of Salamanca, in the region of Castile and León, north of the Sierra de Francia, spanning ten municipalities including San Miguel de Valero. How large is this protected area? Approximately 11,100 hectares. What is the highest peak in the range? Pico Cervero, at 1,465 meters above sea level. Why was the area given UNESCO recognition? Because of the excellent conservation state of its ecosystems, high biodiversity (close to 2,000 plant species, including endemic ones), and the presence of rare birds of prey, which led to its inclusion in the Sierras de Béjar y Francia Biosphere Reserve in 2006. Which rivers flow through this area? The Alagón and Quilamas rivers, along with the Palla stream.

Reserva natural de Lagunas de Villafáfila

Villafáfila

Reserva natural de Lagunas de Villafáfila is a large protected area in the northeastern part of the province of Zamora, within the Tierra de Campos region of Castile and León, Spain. Covering nearly 33,000 hectares of flat farmland dotted with shallow, brackish lagoons, the reserve alternates between dry summers and water-filled autumns and winters, when the wetlands come alive with birds. What makes this reserve special? Villafáfila is best known as one of the most important bird habitats on the Iberian Peninsula, particularly during the autumn-winter season when the lagoons fill with water and become a resting and wintering ground for large numbers of migratory species. The combination of steppe farmland and seasonal wetlands makes it a rare meeting point for two very different groups of birds: waterfowl and dryland steppe species. Which birds live here? The reserve's signature species is the great bustard. The dryland fields surrounding the lagoons support one of the largest populations of great bustards in Europe, with around 2,000 individuals — roughly ten percent of the entire world population of the species. Bustards are large, shy, ground-dwelling birds, and spotting one in the open fields, often at a distance, is a memorable moment for birdwatchers precisely because the species is so wary of people. Cranes are the reserve's other emblematic bird. They appear here as wintering or passage visitors, using the fields around the lagoons as a stopover on their journey toward wintering grounds in Extremadura and Andalusia. Flocks of cranes crossing the sky above the lagoons at dusk, calling as they fly, are one of the most memorable sights associated with this place. Beyond bustards and cranes, the reserve hosts an enormous concentration of waterbirds — it is estimated to gather nearly half of all the waterfowl recorded in official counts across Castile and León. Ducks, waders, herons and other wetland species make use of the seasonally flooded lagoons to feed and rest during their migrations. When is the best time to visit? Autumn and winter are the best seasons for birdwatching, when water levels in the lagoons are highest and bird numbers peak, bringing in cranes and the largest gatherings of waterfowl. Spring, on the other hand, is the season to observe great bustard courtship displays in the open fields, one of the most spectacular natural events in the region. How to plan a visit? Because many of the reserve's birds — especially the bustards — are extremely shy, visitors are encouraged to watch from designated viewpoints, keep noise to a minimum, and maintain a respectful distance. The terrain is flat and open, so binoculars or a spotting scope are recommended. Moving slowly along marked roads, whether on foot or by car, and avoiding walking into the open fields helps prevent disturbing the wildlife. Frequently asked questions Can great bustards be seen at Villafáfila all year round? Great bustards live in the area year-round, but they are easiest to observe in spring, during the breeding season, when males display in the open fields. When do cranes arrive at the reserve? Cranes arrive in autumn and winter, using the lagoons as a stopover on their way to wintering grounds further south in Spain. Is the reserve easy to visit for tourists? Yes, the terrain is flat and open, with roads around the lagoons that allow birdwatching without entering the protected fields, minimizing disturbance to the wildlife.

Arribes del Duero Natural Park

Villarino de los Aires

Arribes del Duero Natural Park is a large protected area in western Spain, within the autonomous community of Castile and León, covering more than 1,061 square kilometers. The park takes its name from "arribes," the local term for the steep, plunging riverbanks that define this rugged stretch of the Duero valley. Where exactly is the park located? The natural park spans territory across the provinces of Salamanca and Zamora, right along the border with Portugal. Here, the Duero river itself forms the international boundary between Spain and Portugal. Protection of this landscape doesn't stop at the border, either — the Portuguese side of the same river valley is safeguarded as the Douro International Natural Park. Together, the two parks form a shared cross-border conservation area along the Duero, even though each country manages its own portion independently. What makes this landscape so distinctive? The defining feature of Arribes del Duero is the terrain the river has carved over time. The Duero, along with the numerous smaller watercourses that feed into it, has spent millennia eroding deep valleys and gorges into the rocky bedrock, producing dramatic, near-vertical precipices in places. These steep-walled canyons give the park a raw, dramatic character that sets it apart from the gentler, more cultivated countryside typical of much of Castile and León. Why is biodiversity such a central part of the park's identity? Alongside its striking geology, the park is recognized for its rich biodiversity. The network of watercourses — from the main Duero channel to its tributary streams — creates a range of habitats that support a wide variety of species. It is this combination of dramatic, water-carved terrain and the biodiversity it sustains that led to the designation of this stretch of the Duero valley as a protected natural park. How large is the park and where is its center located? The park covers 1,061.05 km2 (409.67 sq mi), making it one of the more extensive protected areas in this part of Spain. Its approximate central coordinates are 41.32°N, -6.40°W, in the vicinity of towns such as Villarino de los Aires, which sits directly on the banks of the Duero along this border section of the river. Frequently asked questions How does Arribes del Duero relate to the Douro International Natural Park? Both parks protect the same border river, the Duero, but sit on opposite sides of the frontier: Arribes del Duero on the Spanish side, in Castile and León, and the Douro International Natural Park on the Portuguese side. They function as two separate but complementary protected areas along a shared river valley. Which Spanish provinces does the park cover? The park lies within the provinces of Salamanca and Zamora, both part of the autonomous community of Castile and León. Where does the name "Arribes" come from? It comes from the local word used to describe the steep, precipitous riverbanks carved by the Duero — the same eroded landscape that gives the entire region, and the park, its name. What is the park's most notable natural feature? Its terrain stands out most: deep valleys and vertiginous cliffs shaped by the Duero's erosive power over thousands of years, combined with the rich and varied wildlife that the river's network of habitats supports.

Urbasa-Andia nature park

Urbasa mendia

Urbasa-Andía Natural Park spans two mountain ranges in northern Navarre, Spain – the Sierra de Urbasa and the Sierra de Andía – along with the neighboring Améscoas hills and a protected reserve around the source of the Urederra river. Covering more than 21,000 hectares, the park rises from around 835 meters above sea level up to the summit of Beriáin, which reaches nearly 1,492 meters. It holds one of the largest beech forest areas in Spain and stands as a textbook example of a karst landscape. How did this landscape form? Around 65 million years ago, the area now occupied by the Urbasa and Andía ranges lay beneath a sea. Remains of corals, crustaceans and fish accumulated on the seabed, were compressed over time, and hardened into the limestone bedrock that underlies the park today. Centuries of water erosion acting on this limestone base produced the karst features the park is known for: caves, ravines, sinkholes and underground water channels that vanish beneath the surface only to reappear elsewhere as springs. What can visitors find inside the park? Beech forest is the dominant feature of the vegetation, covering the high plateaus and north-facing slopes of both mountain ranges. Alongside the forest, mountain pastures have long been used by local livestock farmers. One of the park's best-known viewpoints, Balcón de Pilatos, offers sweeping views over the Améscoa valley from a rocky ledge. Within the park boundaries lies a separate nature reserve protecting the source of the Urederra river, famous for its strikingly clear, turquoise-tinted water and a series of small waterfalls along its course. The park also preserves traces of ancient human presence. Archaeologists have identified megalithic monuments here, including dolmens, burial mounds and standing stones, evidence that these highlands were inhabited long before recorded history. What can tourists do here? A network of marked, themed trails allows visitors to explore the park on foot, by bike or on horseback. Most routes are rated as easy, winding through beech woodland, open grazing land and toward scenic viewpoints. A visitor center near the Olazti-Olazagutía entrance provides maps, trail condition updates and guidance for navigating the karst terrain safely. When is the best time to visit Urbasa-Andía? The park is open year-round, but spring and autumn are the most popular seasons, when the beech forest displays its most vivid colors and temperatures are comfortable for longer hikes. In summer, the area around the Urederra springs draws visitors seeking cool water and shade under the tree canopy, while winter blankets the landscape in snow and frost, attracting those looking for quiet, contemplative walks. Frequently asked questions Is the park suitable for families with children? Yes, many trails are rated easy and follow relatively flat terrain, though it's worth checking the length of a specific route before setting out. Does the park have marked trails and visitor infrastructure? Yes, there is a visitor center at the Olazti-Olazagutía entrance along with a network of marked, themed footpaths. What is worth seeing beyond the beech forests? The Balcón de Pilatos viewpoint and the Urederra river source reserve are the two most recommended highlights within the park. Is the karst landscape safe to explore without a guide? Karst features such as sinkholes and fissures call for caution, so it's advisable to stick to marked trails, especially in the park's less-frequented areas.

Serra Gelada and Litoral de la Marina Baixa

l'Alfàs del Pi

Parque Natural de la Sierra Helada (Serra Gelada in Valencian) is a stretch of coastal cliffs spanning the municipalities of Benidorm, l'Alfàs del Pi and Altea on the Costa Blanca, in the province of Alicante. The natural park covers more than 5,000 hectares, a large part of which is marine territory protecting the seabed and its meadows of Posidonia oceanica — a marine plant essential for water clarity and biodiversity in the Mediterranean. The name "Sierra Helada" ("Frozen Range") comes from the pale, frost-like colour of the rock face when seen from a distance. What makes this park special? The park's defining feature is a line of cliffs rising more than 300 metres above the sea, among the highest on Spain's Mediterranean coast. The ridge overlooks Benidorm's bay on one side and the quieter coast of l'Alfàs del Pi on the other, with viewpoints stretching out to the Benidorm Island (Illa de Benidorm) on the horizon. What can you find inside the park? The protected area combines sea cliffs, fossil dune formations, Mediterranean scrubland and small islets where seabirds nest undisturbed. It is home to the peregrine falcon, one of the fastest predators on the planet, along with petrels and other seabird species that rely on the cliffs' inaccessibility for safe breeding grounds. The surrounding waters host bottlenose dolphins, while the seabed's Posidonia meadows shelter coastal fish, sea urchins and other marine life. On land, plant species adapted to salty, rocky conditions are protected within flora micro-reserves established inside the park's boundaries. How can you explore Sierra Helada? The best-known route follows the ridge crossing between Benidorm and the Albir Lighthouse (Faro del Albir) in l'Alfàs del Pi, covering around 8 kilometres and taking roughly 4 hours one way. The trail winds through pine groves and typical Mediterranean vegetation, passing a series of viewpoints over the coastline. Because of steep climbs, little shade along most of the route and considerable elevation change, it is recommended for hikers with good fitness and sure footing — sturdy shoes, water and sun protection are essential, especially in summer. A shorter and easier alternative is the walk to the Albir Lighthouse itself, a mostly flat, paved path along the coast suitable for less experienced visitors. When is the best time to visit? Since the ridge trails offer little shade, spring and autumn are the best seasons for longer hikes, when temperatures are milder. In summer, early mornings or late afternoons are recommended to avoid the hottest hours of the day. Frequently asked questions Where exactly is Sierra Helada located? The natural park stretches along the coast between the towns of Benidorm, l'Alfàs del Pi and Altea, in the province of Alicante, on Spain's Costa Blanca in the Valencian Community. Is there an entrance fee? No, access to the trails is free — the park is an open natural area available to walkers and cyclists on its marked routes. Is the ridge crossing difficult? Yes, the full ridge crossing between Benidorm and the Albir Lighthouse requires good physical condition due to the steep sections and overall length — it is not a walk for beginners. What else can I see besides the landscape? Beyond the cliff and sea views, visitors can spot seabirds, including the peregrine falcon, and with some luck, dolphins swimming along the coastline from the park's viewpoints.

Natural Park River Cabriel

Venta del Moro

Parque Natural de las Hoces del Cabriel is a vast protected landscape stretching along the gorges carved by the Cabriel River, spanning the municipalities of Villargordo del Cabriel, Requena and Venta del Moro in the Valencian Community. Covering more than 31,000 hectares, it is the largest protected natural area in the entire Comunitat Valenciana, and its ecological significance was formally recognized in 2019, when the Cabriel River valley was listed by UNESCO as a Biosphere Reserve. What defines the landscape of the park? Over thousands of years, the Cabriel River has cut deep into the limestone bedrock, forming the winding gorges (in Spanish, "hoces") that give the park its name and its defining character. Along the riverbanks survives one of the best-preserved riparian forests in the whole of the Valencian region — galleries of poplars, willows and tamarisks form a green corridor that stands out sharply against the dry, rocky terrain typical of Spain's interior. What wildlife can visitors expect to see? The park is renowned for an exceptionally rich population of birds of prey, making it one of the most important sites for raptors in the entire province of Valencia. Species nesting along the rocky cliffs of the gorges include the golden eagle, Bonelli's eagle, kites and falcons, along with smaller owls such as the little owl. Birdwatching from viewpoints overlooking the canyon is one of the main draws for naturalists and wildlife photographers visiting the area. Where should a visit start, and what is the visitor center in Venta del Moro? The natural starting point for exploring the park is the Interpretation Center located on Calle Sindicado Agrícola in Venta del Moro. The facility serves both as the management office for the protected area and as an exhibition space where the Cabriel River takes center stage, presenting the local ecosystem's flora, fauna and geology. It is a useful stop before heading out on the trails, offering guidance on which routes are open and which species are more likely to be spotted depending on the season. What activities does the park offer? Hoces del Cabriel appeals both to visitors seeking a quiet walk in nature and to those after a stronger adrenaline rush. Available activities include hiking along the canyon rims, fishing in the waters of the Cabriel River, and adventure sports such as rafting and bungee jumping, which make use of the gorge's characteristic high rock walls. This variety of options means the park attracts families looking for a nature getaway as well as active travelers drawn to water sports and climbing. Why combine a visit with a stay in Venta del Moro? Venta del Moro, one of the municipalities within the park's boundaries, is sometimes referred to as the "capital of Hoces del Cabriel" thanks to its proximity to the management center and convenient access to the trail network. It makes a practical base for anyone planning a longer stay in the region, allowing visitors to pair exploration of the gorges with a taste of the local culture and history of this inland part of Valencia, away from the coast and the more conventional tourist routes. Frequently asked questions Is the park suitable for families with children? Yes, the gentler hiking sections and the visit to the Interpretation Center are accessible to visitors of all ages, though the adventure sports require proper preparation. What is the best time of year to visit? Spring and autumn offer milder temperatures for hiking and birdwatching, well suited to the dry climate typical of inland Valencia. Is entry to the park free? The protected landscape itself is open to the public, and the Interpretation Center in Venta del Moro provides information on any fees that may apply to specific activities, such as rafting.
