Estany des Ponts (Lago Esperanza)
Platja d'Alcúdia
Estany des Ponts (Lago Esperanza) is a lake on the edge of Platja d'Alcúdia, on Mallorca's north coast — a surviving fragment of the once-extensive wetland complex of Alcúdia bay, linked to the neighbouring s'Albufera nature park. How to get there? The lake sits roughly 3 km from Alcúdia town centre, between Platja de Muro to the south and the Xara district to the north, right beside the beach strip of Port d'Alcúdia. Car or bike are the easiest ways in — the area forms part of northern Mallorca's walking and cycling network, and the loop around the lake shows up as a stop or starting point on routes documented on Komoot and Wikiloc. From the tourist hubs of Port d'Alcúdia, it's only a short drive away. What will you see? Estany des Ponts, better known locally as Lago Esperanza ("Lake of Hope"), spent decades as one of the most degraded lakes on the island. Development began here in the 1970s but was never completed, leaving the plot ownerless and, for years, an illegal dumping ground for rubble. Since 2023 the site has been under a restoration programme called "RestaurAlcúdia," funded with three million euros through Spain's Biodiversity Foundation (Ministry for Ecological Transition) and EU Next Generation funds. The project aims to rebuild the ecological corridor connecting the Maristany and s'Estany des Ponts wetlands. A footpath runs around the lake's perimeter: the eastern shore is mostly paved and easy walking, while the western shore stays more natural — earthen ground, in places closer to cross-country terrain. That mix makes the lake a spot for both quiet wildlife watching and casual walking or cycling. The biggest change on the horizon is the lake's conversion into an international canoeing and rowing venue. The planned regatta course will include nine competition lanes, judges' towers, pontoons and a mobile platform to support training and events. Construction of this sporting infrastructure is confirmed to begin in 2026, following years of debate among local authorities over the project. When to visit? Spring and autumn bring the best conditions for walking the lakeside path and watching waterbirds, since temperatures are milder than at the height of summer. In summer the area is mostly visited alongside time on the neighbouring beaches of Port d'Alcúdia and Platja d'Alcúdia, while outside the tourist season the lake keeps a quieter, more natural character — especially early in the morning. Frequently Asked Questions How is Estany des Ponts different from the nearby Albufera? S'Albufera is a large, official nature park with well-developed visitor infrastructure, while Estany des Ponts is a smaller, formerly neglected piece of the same original Alcúdia bay wetland system, now undergoing restoration. Can you swim there? No — the lake isn't set up for swimming. It's a walking and nature spot, and eventually a sporting one too (canoeing, rowing), rather than a beach. Does the ongoing restoration make it hard to visit? Work under the RestaurAlcúdia programme mainly involves replanting vegetation and rebuilding the ecological corridor; the walking path around the lake stays open to visitors. How far is it from the beach? The lake sits directly next to the beach strip of Port d'Alcúdia and Platja d'Alcúdia, so it's only a few minutes' walk to the water.

Meirama Lake
Cerceda
Meirama Lake, in the municipality of Cerceda (A Coruña province, Galicia), is one of Spain's most striking landscape transformations: a former open-pit lignite mine turned into a large, deep artificial lake. Where did the lake come from? The Meirama mine operated continuously from 1980 until January 2008, supplying lignite to the adjacent Meirama thermal power plant for 27 years and yielding a total of 94 million tonnes of coal. When mining stopped, the site's owner — today Naturgy, formerly Gas Natural Fenosa — launched one of Spain's largest post-mining restoration projects, investing around 60 million euros to flood the enormous pit and replant the surrounding spoil heaps. The result is an artificial lake roughly 2.2 km long and 1 km wide, covering about 171 hectares, with a maximum depth of around 205 metres — among the deepest bodies of water in Spain. The water is exceptionally clean, and since 2013 Galicia's water authority (Aguas de Galicia) has approved its use as an emergency drinking-water reserve for the city of A Coruña, some 30 km away, without the need for intensive treatment beforehand — reportedly the first artificial lake of its kind in Spain to be cleared for this purpose. What will you see? The land around the lake has been reforested and turned into a protected natural area that is gradually attracting waterfowl and other wildlife. A walking trail circles the reservoir, offering views over the water framed by the reforested slopes of the former mine — the contrast between the site's industrial past and its current calm is part of what makes a visit worthwhile. It's a popular spot with locals for walking, birdwatching and landscape photography, though swimming and water sports are restricted given the lake's role as a drinking-water reserve. How to get there? Meirama Lake sits in Cerceda, about 25–30 km from A Coruña, and is easily reached by car via local roads into the As Encrobas valley. It makes a good stop for anyone exploring the inland parts of A Coruña province and looking for a quieter, less touristy corner of Galicia. When to visit? Spring and autumn offer the best conditions for walking and wildlife-watching, with lush greenery around the lake and fewer visitors than in summer. Summer brings longer, warmer days that suit longer walks around the reservoir, though weekends tend to draw more visitors. Frequently asked questions Is Meirama Lake a natural lake? No — it's an artificial reservoir created by flooding a former open-pit lignite mine that operated until 2008. Can you swim in the lake? Because it serves as a drinking-water reserve for A Coruña, swimming and water sports are restricted; the lake is mainly a destination for walking and nature watching. How deep is the lake? Its maximum depth is around 205 metres, making it one of the deepest bodies of water in Spain. How long did the site's restoration take? The rehabilitation project, worth roughly 60 million euros, involved flooding the mine pit and reforesting the surrounding spoil heaps and land, creating the lake landscape seen today.

Lagoas de Alcaián
Coristanco
Lagoas de Alcaián is a natural peat lake in the parish of Seavia, in the municipality of Coristanco, in the province of A Coruña, Galicia. Locally known as Braña Rubia, it stands out among the region's wetlands for both its ecology and the folklore attached to it. Where it is and what it looks like The lake sits on flat ground in the so-called Depresión Meridiana, where impermeable basic rock keeps water from draining away. It covers roughly 0.4 km² (about 55 hectares), stretching some 1.5 km in length and up to 400 m in width, and drains through the small Regato de Brañas Rubias stream. Because of its peaty bed and surroundings, the site is best described as a peatland lake rather than a mountain or coastal lagoon in the usual sense. Why the site is protected Lagoa de Alcaián and the surrounding Braña Rubia area have been designated an Espazo Natural de Interese Local (a locally protected natural area) by the Coristanco town council, and the wetland is also listed in Galicia's regional wetland inventory. That protected status is meant to safeguard the peat-bog ecosystem, which supports a range of plant, animal, and fungal species characteristic of Galician wetlands. The legend of the drowned village The name Alcaián is tied to one of Galicia's best-known submerged-village legends. According to local tradition, a village once stood where the lake is today, but its residents refused to give alms to Saint Peter — in other versions, to Christ himself — who was travelling through in the guise of a beggar. As punishment for their lack of charity, the village was flooded and vanished beneath the water. This "drowned village as divine punishment" motif recurs across several Galician lake legends, placing Alcaián within a broader regional oral tradition. Other things worth knowing The area around the lagoon also has archaeological interest, with finds pointing to earlier human settlement nearby. At the same time, some sources note environmental problems at the site, including illegal peat extraction and waste dumping linked to a past lack of adequate protection — worth keeping in mind if you visit, since the wetland ecosystem is fragile and best treated with care. Frequently Asked Questions Where is Lagoa de Alcaián located? In the parish of Seavia, municipality of Coristanco, province of A Coruña, Galicia, in an area known as Braña Rubia. How large is the lake? It covers about 0.4 km² (roughly 55 hectares), is around 1.5 km long, and up to 400 m wide. Is the site protected? Yes. It has been designated an Espazo Natural de Interese Local by the Coristanco municipality and is included in Galicia's regional wetland inventory. What legend is associated with the lake? Local tradition holds that a village was flooded as punishment for refusing alms to Saint Peter, or to Christ, who appeared disguised as a beggar — a motif shared with several other Galician lake legends.

Sanabria Lake
Galende
Lago de Sanabria is the largest glacial lake on the Iberian Peninsula, located in the municipality of Galende, in the province of Zamora, in the region of Castile and León. Where is Lago de Sanabria located? The lake sits in the historic comarca of Sanabria, in the northwestern corner of Zamora province, close to the borders with Portugal and Galicia. The municipality of Galende, which contains the lake, is made up of several villages scattered along its shores. The rugged, mountainous character of this part of Castile and León — marked by glacial valleys and rocky terrain — is precisely what allowed such a large natural lake to form here. What makes this lake stand out among Spain's lakes? Most of Spain's large bodies of water are artificial reservoirs, which makes Lago de Sanabria an exception — its origin is entirely natural. A glacier that once covered the area carved out the lake basin thousands of years ago, leaving behind the distinctive moraine ridges still visible in the surrounding landscape today. This glacial origin makes the lake a reference point for anyone interested in the history of glaciation on the Iberian Peninsula. What else is there to see nearby? The land around the lake forms part of the Lago de Sanabria Natural Park, which also includes smaller mountain lakes, river valleys, and highland areas covered in oak and birch forest. The protection here extends to the whole glacial ecosystem, not just the lake itself. Nearby Puebla de Sanabria, the historic capital of the region, has preserved its medieval town layout and old castle, making it a natural base for visiting the lake. How do you get there? Galende lies inland, in a mountainous part of Zamora province, which in practice means getting there requires your own transport — public transport options in this region are limited. The nearest larger town is Puebla de Sanabria, from where local roads lead toward the lake and the surrounding villages. Frequently Asked Questions Is Lago de Sanabria a natural lake or an artificial reservoir? It is a natural lake, formed by glacial activity during the Pleistocene — this is its key distinction from many of Spain's other large bodies of water, which are man-made dams. Which region of Spain is the lake in? The lake lies in the province of Zamora, in the region of Castile and León, within the municipality of Galende, in the historic comarca known as Sanabria. Is the area around the lake protected? Yes, the surrounding land is part of a natural park that covers Lago de Sanabria together with the neighboring mountain terrain and smaller glacial lakes. What's the nearest town for travelers to use as a base? Puebla de Sanabria, the region's historic capital with a well-preserved medieval center, is the natural starting point for planning a visit to the lake.

Lagunas de Río Seco
Capileira
Lagunas de Río Seco is a cluster of high-mountain glacial lakes in the municipality of Capileira, deep in the Sierra Nevada range in Andalusia. Prized by hikers for their stark, high-altitude scenery and remoteness, they form part of a wider network of lagunas scattered across the highest reaches of this Spanish mountain range. What exactly are the Lagunas de Río Seco? Despite the name, Río Seco is not a single lake but a group of eight separate water bodies. Most are seasonal: they fill in spring as snowmelt runs down from the peaks, then shrink or dry up entirely by summer. They sit within the alpine zone of the Sierra Nevada, an area protected as both a National Park and a Natural Park. The site's coordinates are roughly 37.053°N, 3.347°W. How do you reach Río Seco from Capileira? The most common approach starts in Capileira itself. Two trailheads leave the village — one via La Cebadilla, the other via Las Acequias — both converging at Cortijo de las Tomas and continuing to Refugio Poqueira, a mountain refuge that serves as the natural rest stop along the way. From there the path continues toward the Mulhacén river. A second option follows the forest track connecting Veleta and Capileira. Hikers travelling with children, or anyone after a shorter outing, can instead take the National Park shuttle bus to Posiciones del Veleta — from that point, reaching the lagunas takes no more than two hours on foot. Is there a circular route linking the Sierra Nevada lagunas? Yes. A longer circular route, popular with experienced hikers, starts at Refugio Poqueira and heads toward the Mulhacén river, climbs to Laguna de la Caldera, crosses the Collado del Ciervo pass to a spot known as La Mosca, continues via Juego de Bolos to Laguna Larga, and finally descends to Laguna de Río Seco. It's the way to see several of the range's high-altitude lakes in a single trip. When is the best time to hike here? This circular route is recommended for summer only. In winter, the path becomes hazardous — snow and ice on the exposed high-altitude sections call for mountaineering experience and gear, not standard trekking equipment. What should you know before setting out? Capileira, the starting point for most routes, sits where the Sierra Nevada National Park and Natural Park meet, so the municipality offers a wide range of trails beyond the lagunas themselves, at varying difficulty levels. Bring proper hiking boots, plenty of water, and sun protection — the high-altitude stretches are largely treeless and exposed. Frequently Asked Questions Do the Lagunas de Río Seco hold water all year? No. Most of the eight water bodies are seasonal, filling mainly in spring from snowmelt and largely drying up by summer. How long does the hike from Capileira take? It depends on the route. The classic approach via Refugio Poqueira takes most of a day, while using the National Park shuttle to Posiciones del Veleta cuts the walk down to around two hours. Is the trail suitable for children? The shorter option using the shuttle to Posiciones del Veleta is easier and better suited to families than the full circular route through several lagunas. Can you visit in winter? The circular route through the lagunas is recommended for summer only — winter conditions on the high-altitude sections make it dangerous.

Lagunillos de la Virgen
Dílar
Lagunillos de la Virgen is a group of three small mountain tarns on the western face of Sierra Nevada, within the municipality of Dílar, sitting at around 2,950 meters above sea level. This is one of those spots hikers only find once they leave the crowds near the ski resort behind — a quiet basin of granite and water that feels worlds away from the Granada valley far below. Where exactly are the Lagunillos de la Virgen? The tarns sit in the upper reaches of the Río Dílar valley, inside Sierra Nevada National Park. Three small basins collect snowmelt and rainwater, and their overflow drains toward the west-southwest, feeding the headwaters of the Río Dílar. It's the runoff from the third tarn, combined with water from the nearby Laguna de las Yeguas, that actually starts the river on its journey down to the fertile Vega de Granada. How do you get to the Lagunillos de la Virgen? Most hikers start from Hoya de la Mora, the upper part of the Sierra Nevada ski station, reachable by summer bus service from Granada or by chairlift during winter. From there, the walk to the tarns typically takes two to three hours depending on pace and fitness. The trail crosses classic high-Sierra Nevada terrain — open slopes, rocky paths, and mountain streams — with little to no shade along most of the route, so an early start pays off. An alternative approach climbs directly from the village of Dílar, following the river valley and passing the Chorreras del Molinillo waterfall on the way. It's a more scenic but longer option for anyone who wants to trace more of the river's course from source to village. What will you see once you're there? The tarns themselves are modest in size, but their surroundings are the real draw. They sit amid borreguiles — the high-altitude wet meadows and peat bogs typical of Sierra Nevada, fed by snowmelt and mountain springs. These meadows host numerous plant species found nowhere else but this range. Water from the lakes spreads out through countless small channels that keep the peatlands damp throughout the summer months. Views from here take in the western peaks of Sierra Nevada and, on a clear day, a distant panorama toward Granada and the Genil valley. The area draws high-mountain trekkers and nature photographers alike, especially in late spring and early summer when the tarns are at their fullest. When is the best time to visit? The main hiking season runs roughly from June to October, once snowmelt clears the trails and fills the tarns. Earlier in spring, snow can still linger at this altitude, making the route more demanding and better suited to experienced hikers with proper gear. Summer offers the most reliable access, though the exposed slopes mean strong sun for most of the day — pack accordingly, since shade is scarce along the way. Frequently asked questions Is the hike to Lagunillos de la Virgen difficult? It's a demanding but non-technical high-mountain trail. Fitness matters given the altitude (nearly 3,000 m) and the length of the approach (2–3 hours one way from Hoya de la Mora), but no climbing gear is needed during the summer season. Can you drive close to the tarns? Not directly to the lakes, but you can drive or take the bus to Hoya de la Mora, which is the most convenient starting point for most visitors, and continue on foot from there. Are there other tarns worth visiting nearby? Yes — Laguna de las Yeguas sits in the same area, and its waters join the outflow from Lagunillos de la Virgen to form the headwaters of the Río Dílar. Many hikers combine both stops in a single outing. Do you need a permit to enter Sierra Nevada National Park? Walking the main marked trails doesn't require a special permit, but it's worth checking current access rules for specially protected zones and any seasonal restrictions before heading out.

Estany de Sotllo
Alins
Estany de Sotllo is a glacial lake set within the municipality of Alins, in the Pallars Sobirà region of Catalonia, right in the heart of the Pyrenees. The lake is fed by water flowing down from the nearby Estany d'Estats and, in turn, regulates the flow of the Barranc de Sotllo stream, which later joins the Noguera de Vallferrera river. The surrounding ridgeline includes some of the highest peaks in the Catalan Pyrenees — Pica d'Estats, Pic de Sotllo, and Punta Gabarró — making the lake one of the standout viewpoints in this stretch of the mountains. How to get there? The starting point is the village of Alins, located in the Vallferrera valley, one of the side valleys of Pallars Sobirà. From Alins, a hiking trail follows the Barranc de Sotllo stream upward through the valley until it reaches the lake basin. The route is mountainous, crossing rocky and steep terrain, so it's best treated as a full-day outing with an early start. Cars can reach the trailheads near Alins, but the rest of the way is on foot only. What will you see? Estany de Sotllo offers the raw, high-mountain scenery typical of glacial cirque lakes. Its deep blue water contrasts sharply with the rocky slopes and towering peaks enclosing the basin on every side. It's a place of silence and open space, far from any crowds, with views over some of the tallest sections of the Catalan Pyrenees. For anyone interested in geology or high-mountain nature, the lake is a striking example of the region's glacial landscape. When to visit? Summer, from June to September, is the best time to visit, when the trails are clear of snow and weather in the higher elevations tends to be stable. In early spring and late autumn, the upper stretches of the route can still be covered in snow or ice, making the lake much harder to reach. An early start is recommended, since mountain weather can change quickly during the day, with storms most common in the afternoon. Practical tips Reaching the lake calls for a reasonable level of fitness and proper hiking boots, since the terrain is mountainous and demanding in places. Bring enough water, food, and clothing to handle sudden weather shifts, which are common in this part of the Pyrenees. Given the distance from any settlement and the lack of tourist infrastructure right by the lake, it's wise to let someone know the planned route and expected return time. Frequently asked questions Is it hard to get to Estany de Sotllo? Reaching Alins itself is straightforward, but getting to the lake requires a multi-hour hike over mountain terrain, so it's best planned as a full-day trip. Can you swim in the lake? Water in high-altitude glacial lakes like this one tends to stay very cold year-round, so swimming isn't a typical draw here. Is the trail well marked? The routes through the Vallferrera valley leading to its glacial lakes form part of the wider hiking trail network of the Pallars Sobirà region, popular with hikers and mountaineers. Are there other lakes worth visiting nearby? Yes — the same area, within the Alins municipality, holds several other glacial lakes, including Estany d'Estats, which feeds into Estany de Sotllo; the region is known for its cluster of lakes of this kind.

Estany de Baborte
Alins
Estany de Baborte is a glacial lake in the municipality of Alins, in the Vallferrera valley, within the Alt Pirineu Natural Park in the Spanish Pyrenees (Lleida province, Catalonia). It sits at 2,337 metres above sea level, making it one of the higher lakes in this part of the range. How do you get there? The starting point is the Farga car park. From there the trail runs past Bordes de la Rebuira to Cabana de Basello (1,971 m), then joins the GR-TRF route for the final climb known as the "costa de Llats." The ascent is demanding and calls for good fitness and proper trekking footwear. An early start is advisable so you can be back down before dusk, especially in summer when afternoon storms are common in the Pyrenees. What will you see? The lake has an elongated shape running from northwest to south, a maximum length of 519 metres, and a surface area of 6.86 hectares. It sits within a ring of peaks that give the spot the feel of a true glacial cirque: Pic de Llats (2,693 m) to the east, Tres Pics (2,648 m) to the west, Pic de Baborte (2,934 m) to the north, and Pic de Pedres Blanques (2,765 m) to the northeast. The water carries the deep turquoise-grey tone typical of high-mountain lakes, shifting with the light and cloud cover through the day. Just above the lake, at the foot of the Baborte cirque, stands the Refugi del Cinquantenari, also known as Refugi de Baborte. It's an unmanned, orange-coloured bivouac-style shelter owned by the Unió Excursionista de Catalunya, with room for 16 people. It was built and inaugurated on 12 September 1981 to mark the club's fiftieth anniversary. For many hikers, the refuge is the natural resting point before pushing on further, or a base for longer trips across the surrounding ridges. Estany de Baborte also serves as a starting point for more ambitious high-mountain ascents — to Pic de Baborte (2,934 m), Pic dels Estanys (2,955 m), and Pic del Sotllo (3,073 m). Worth noting: the same municipality of Alins holds two other, separate lakes — Estany d'Estats and Estany de Sotllo — each in its own cirque, so it's worth double-checking which trail actually leads to Baborte when planning a trip. When should you visit? The best season to visit is summer, from June to September, when the trail is free of snow and the weather is at its most stable. Earlier in spring or later in autumn, snow can linger on the higher sections of the approach and daylight hours shrink, making a safe return harder. In winter the route calls for the gear and experience needed for high-mountain snow travel. Frequently asked questions Is the hike to Estany de Baborte difficult? Yes, it's a demanding high-mountain route with substantial elevation gain over rocky terrain and steep climbs. Good physical condition and proper preparation are recommended. Can you stay overnight near the lake? Yes, the Refugi del Cinquantenari (Refugi de Baborte) is nearby — an unmanned bivouac shelter for 16 people, open without reservation. Which peaks surround the lake? The cirque is formed by Pic de Llats, Tres Pics, Pic de Baborte, and Pic de Pedres Blanques, and the lake also serves as a starting point for Pic dels Estanys and Pic del Sotllo. Is the route suitable for families with children? Given the length, elevation gain, and rocky high-mountain character of the trail, it suits experienced mountain hikers better than families with young children.

Gerber Lake
Alt Àneu
Gerber Lake (Catalan: Estany de Gerber) is one of the largest and deepest glacial lakes in the municipality of Alt Àneu, deep in the Catalan Pyrenees. Where is Gerber Lake located? The lake sits at roughly 2,170 metres above sea level, in the upper reaches of the Àneu Valley (Valls d'Àneu), close to the border with the Val d'Aran. It lies within the peripheral zone of the Aigüestortes i Estany de Sant Maurici National Park and borders the Alt Pirineu Natural Park. Covering 14.4 hectares and reaching a depth of 63 metres, it stands out as one of the few large lakes in the region left untouched by the hydroelectric engineering that has reshaped many other Pyrenean lakes. How do you get there? Most visitors start from the large car park next to the lower station of the La Peulla chairlift, reached by the road climbing towards the Port de la Bonaigua pass. From there, the trail winds through a forest of black pine and thickets of rhododendron before opening out onto the high-altitude meadows surrounding the lake. The path is rocky in places but well trodden and clearly marked, making it accessible to hikers of average fitness. What will you see along the way? The popular route to the lake runs between roughly 7.2 and 8.5 km round trip, with an elevation gain of 290–350 metres, taking anywhere from just over an hour for the shorter waterfall detour to about 4 hours for the full round trip. Along the way, hikers pass the striking Cascada de Gerber, a waterfall cascading over the rocks. The scenery shifts noticeably over the course of the walk, from the shaded forest lower in the valley to open, rocky high-mountain terrain with views of the Bassiero massif. The lake itself is known for its vividly turquoise water, standing out against the surrounding meadows and granite ridges. When is the best time to visit? The ideal window for hiking runs from June to October, when the trail is free of snow and the meadows around the lake are at their greenest. During peak summer (July–August), the abundance of water in the streams and waterfall makes the walk especially rewarding. In winter, the route is sometimes covered on snowshoes, though this calls for more mountain experience, proper gear, and checking avalanche conditions beforehand. Frequently asked questions How long is the hike to Gerber Lake? Depending on the exact route chosen, the round trip runs between about 7.2 km and 8.5 km, with 290–350 metres of elevation gain. Is the trail difficult? The route is considered easy to moderate and suitable for most hikers with average fitness, though the altitude above 2,000 metres calls for prior acclimatisation, especially on hot summer days. Are there other lakes worth seeing nearby? Yes — the Gerber Valley (Vall de Gerber) holds several smaller tarns, including Estanyet de Gerber de Baix, which can be visited alongside the main hike without significantly extending the route. Where's the best place to start the hike? The most convenient starting point is the car park by the La Peulla chairlift, reached via the road towards the Port de la Bonaigua pass from the Àneu valley side.

Estany d'Estats
Alins
Estany d'Estats is a high-mountain glacial lake in the municipality of Alins, in the Pallars Sobirà region of Catalonia, Spain. It sits at the foot of Pica d'Estats (3,143 m) — the highest peak in Catalonia — and marks one of the last landmarks on the classic route to the summit. Where is it? The lake lies in the Vall Ferrera valley, deep in the Pyrenees, close to the snowline for much of the year. Its coordinates are approximately 42.657553°N, 1.390004°E. The surrounding landscape is rugged high-mountain terrain, framed by granite ridges typical of the highest reaches of the Catalan Pyrenees. How do you get there? Most visitors start from the village of Àreu, from where a mountain road (about an hour's drive) leads to the Molinassa car park at 1,805 m. From there, a roughly three-hour walk brings you to the Refugi de Vall Ferrera, the oldest federated mountain refuge in Catalonia. The classic route continues from the refuge, marked with white-and-red TRF (cross-border) waymarks, crossing Pales d'Areste into the Sotllo valley. It passes Estany de Sotllo (2,530 m) before reaching Estany d'Estats, right below the summit of Pica d'Estats. The full route to the peak covers around 10 km with 1,338 m of cumulative elevation gain. What will you see? Estany d'Estats is a classic cirque lake, carved by glacial erosion into a rocky basin ringed by steep slopes. Its water carries an intense blue or turquoise hue that stands out against the grey granite walls around it. For hikers heading to Pica d'Estats, the lake is a natural resting point before the final, steepest stretch of the ascent. The wider area around Alins is dense with glacial lakes — besides Estany d'Estats and Estany de Sotllo, the region includes Certascan, considered the largest natural lake in the Pyrenees, along with Pinet, Blaus, and Romedos, making this corner of the municipality one of the richest in high-mountain water bodies across the whole range. When should you visit? Because of the altitude and alpine conditions, snow can linger around Pica d'Estats and Estany d'Estats well into July. The best window for hiking is from late July through September, when the trail is generally clear and snow conditions are more predictable. It's worth checking current snow reports before setting out, since late-spring attempts may require extra mountaineering gear. Frequently asked questions Is the hike to Estany d'Estats difficult? Reaching the lake itself is a demanding but accessible mountain walk for hikers in good physical condition; continuing on to the Pica d'Estats summit is a considerably harder route requiring good navigation skills and proper footwear. How long does it take from the Molinassa car park? Reaching the Refugi de Vall Ferrera takes about three hours, and the onward stretch through the Sotllo valley to Estany d'Estats adds several more hours depending on fitness and conditions. Is there anywhere to stay overnight nearby? Yes — the Refugi de Vall Ferrera, the oldest federated refuge in Catalonia, is the natural base for anyone planning a multi-day trip into the Pica d'Estats area. How is Estany d'Estats different from the nearby Baborte and Sotllo lakes? These are three separate glacial lakes within the municipality of Alins, each in a different part of the valley system. Estany d'Estats sits closest to the Pica d'Estats summit, Estany de Sotllo lies lower down on the approach route, and Estany de Baborte is a distinct lake in another part of the municipality.

Lac de Clòto de Baish
Naut Aran
Lac de Clòto de Baish is a mountain lake in the municipality of Naut Aran, in the Val d'Aran region of Catalonia, Spain. Sitting at roughly 2140 metres above sea level, it covers a modest 1.1 hectares, making it one of the smaller yet especially scenic lakes in this part of the Pyrenees. Where exactly is the lake located? Lac de Clòto de Baish lies within the Cirque de Colomèrs (Circ de Colomèrs), a broad glacial basin dotted with mountain lakes, inside the Aigüestortes i Estany de Sant Maurici National Park. The lake is fed by the outflow of the higher-lying Estany Long (Lac Long), whose stream drops down through a rocky ravine before reaching the Clòto de Baish basin. How do you get there? Most visitors start from the car park at Banhs de Tredos, at an altitude of 1765 metres. From there, the trail follows the Val d'Aiguamòg valley, and the climb up to the lake takes around 2 hours on foot. During summer, from 15 June to 15 September, a seasonal mountain taxi runs from the car park, shortening the approach by carrying hikers closer to the actual trailhead. Outside that window, reaching the area requires a private vehicle, and the entire route must be walked from the car park itself. What will you see along the way? Lac de Clòto de Baish is one of seven lakes that make up the popular hiking circuit known as the Ruta dels 7 Llacs (Route of the 7 Lakes) through the Circ de Colomèrs. The walk crosses typical high-Pyrenean granite terrain, passing a succession of pools in varying shades of turquoise and blue. The views around Clòto de Baish itself are considered among the most striking on the whole route, framed by steep slopes and rocky ridgelines, with the peaks surrounding the Aiguamòg valley visible in the background. When is the best time to visit? Given its altitude of over 2100 metres, the lake is fully accessible mainly in summer, from June to September, once snow clears from the trails and the seasonal taxi service makes reaching the trailhead easier. In spring and autumn the route can be harder going due to lingering snow and the absence of the shuttle service, while winter access demands the equipment and experience typical of high-mountain trekking. Frequently asked questions How long does it take to reach Lac de Clòto de Baish? From the Banhs de Tredos car park, at 1765 metres, the climb through the Val d'Aiguamòg valley takes about 2 hours. Can you drive closer to the lake? Not all the way to the lake itself, but during summer (15 June to 15 September) a mountain taxi service runs from the Banhs de Tredos car park, cutting down the walking approach. How does Lac de Clòto de Baish differ from nearby Estany Long? Estany Long sits higher up and feeds Clòto de Baish through its outflow, which drops down via a rocky ravine — both lakes belong to the same Circ de Colomèrs lake system. Is the lake inside a national park? Yes, Lac de Clòto de Baish lies within the Aigüestortes i Estany de Sant Maurici National Park, inside the Circ de Colomèrs basin.

estany de Bassiero
Alt Àneu
Estany de Bassiero is a small mountain lake in the municipality of Alt Àneu, in the Pallars Sobirà county, right in the heart of the Catalan Pyrenees. It sits at the foot of Pic de Bassiero (2,887 m), the highest point of the north-east-facing basin that surrounds it, next to the Alt Pirineu Natural Park and close to the boundary of the Aigüestortes i Estany de Sant Maurici National Park. It's a destination for hikers who want to get away from the busier trails of the Àneu valley while still experiencing the region's classic scenery of glacial lakes, granite ridgelines and alpine meadows. How do you get to estany de Bassiero? Most routes in this area start from La Peülla, a small settlement in the Alt Àneu municipality, from where trails head up the valley towards Estany Gerber and, further on, towards the Bassiero massif. The stretch to the lake itself calls for a reasonable level of fitness — the ground is rocky, occasionally steep, and the final approach runs above the treeline. It's worth planning for a full day out, since the return leg along the same path takes time and weather in the high Pyrenees can shift quickly. A good rest point along the way is the Refugi Mataró, by Estany Gerber, from where further trails branch off towards peaks such as Pic d'Amitges and Pic de Saboredo. What will you see there? Estany de Bassiero is a typical glacial lake — small, with clear, cold water, hemmed in by rocky slopes and largely free of tall vegetation. Nearby, in the same valley, sits the much larger Estany Gerber, one of the few lakes in the region that has kept its natural state without being altered by hydraulic works — it covers roughly 14.4 hectares and reaches depths of up to 63 metres, making it one of the deeper lakes in the Pyrenees. Towering over the valley is Pic de Bassiero itself, visible from many points along the route, and on a clear day the higher stretches of the trail open up views over the surrounding ridges of the Vall d'Àneu. When's the best time to visit? Summer, from June to September, is the best window for hiking here, once snow has cleared from the higher sections and days are long enough for a full-day trip. In May and June, snow can still linger higher up, making the final approach to the lake harder going. In winter and early spring, the area draws snowshoeing visitors instead — the nearby Estany de Gerber is a popular snowshoe destination — though reaching estany de Bassiero itself at that time of year requires experience and the right gear. Frequently asked questions Is the hike to estany de Bassiero difficult? Yes, it suits hikers with some mountain experience — the terrain is rocky and the approach runs above the treeline, where weather conditions change faster than lower down in the valley. Is there anywhere to stay near the lake? The closest shelter along the route is the Refugi Mataró, by Estany Gerber, from where you can continue on towards the Bassiero massif and nearby peaks. Is the lake inside a national park? It lies right next to the Alt Pirineu Natural Park and close to the boundary of the Aigüestortes i Estany de Sant Maurici National Park, so the surrounding area is under nature protection. How is estany de Bassiero different from estany Negre de Cabanes? They're two separate lakes within the same Alt Àneu municipality but in different parts of the valley — don't confuse them just because they share the same administrative area.

estany Negre de Cabanes
Alt Àneu
Estany Negre de Cabanes is a glacial mountain lake in the municipality of Alt Àneu, in the Pallars Sobirà comarca, tucked away in the Vall de Cabanes at an altitude of 2,178 metres. Covering nearly 7 hectares, it ranks among the larger bodies of water in this part of the Pyrenees. Its name, meaning "black lake," reflects the dark, deep water typical of high-altitude lakes ringed by bare rock and scree. Where exactly is the lake? Estany Negre de Cabanes sits within the peripheral zone of the Aigüestortes i Estany de Sant Maurici National Park, one of Catalonia's most valuable natural areas. It occupies the upper reaches of the Cabanes valley, hemmed in by scree fields on nearly every side — only the eastern shore slopes gently enough for easy access on foot. The Riu de les Abadies feeds into it, along with the outflow from the neighbouring Estany de Xemeneia, while the lake itself drains into the smaller Estanyoleta, forming a left tributary of the Riu de Cabanes. How do you get there? The starting point is Esterri d'Àneu, reachable by car from the main roads of Pallars Sobirà. From there, the route heads toward Refugi del Gerdar, a mountain hut that serves as the natural base for exploring the Cabanes valley further. From the refuge, a hiking trail continues up the valley all the way to the lake itself. The final stretch crosses rocky, scree-covered terrain typical of the high Pyrenees, so a reasonable level of fitness and proper trekking footwear are essential. What will you see there? The scenery around Estany Negre de Cabanes is stark and high-alpine: steep slopes blanketed in scree, dark water mirroring the surrounding peaks, and a silence rarely found on the park's busier trails. Its proximity to the Aigüestortes National Park means visitors may spot mountain wildlife along the way, and the Cabanes valley itself has kept much of its wild, largely untouched character. The spot appeals mainly to hikers and landscape photographers looking for solitude away from the more crowded routes. When is the best time to visit? Given its altitude above 2,100 metres, summer — from June to September — is by far the best window, when trails are clear of snow and Pyrenean weather is at its most stable. In early spring and late autumn, lingering snow and difficult scree conditions can make the approach harder, so it's worth checking current trail conditions in advance, ideally with Refugi del Gerdar. Frequently asked questions Can you drive all the way to the lake? No — a car will only get you as far as Esterri d'Àneu and the approach toward Refugi del Gerdar. The final stretch to Estany Negre de Cabanes has to be covered on foot. Is the trail technically difficult? The hike itself doesn't require climbing gear, but the scree terrain and altitude above 2,000 metres call for a good fitness level and sturdy trekking boots. Can you swim in the lake? Given its high-altitude setting and cold water, swimming isn't practised or recommended here — the lake's main appeal lies in its scenery and natural surroundings. Is the lake inside a national park? Estany Negre de Cabanes lies within the peripheral zone of the Aigüestortes i Estany de Sant Maurici National Park, meaning the area benefits from additional environmental protection.

estany Gelat
la Vall de Boí
Estany Gelat is a small glacial lake in the municipality of la Vall de Boí, tucked into the high-mountain section of the Aigüestortes i Estany de Sant Maurici National Park. Where exactly is it? The lake sits in the Cavallers–Punta Alta massif, inside the side gully of Barranc de Comalesbienes, at an altitude of 2,740 metres. It covers barely 0.8 hectares, and its depth has never been precisely measured — estimates put it somewhere between 6 and 10 metres. The water fills a rocky basin just below the col de Comalesbienes, surrounded almost entirely by bare stone and classic glacial terrain. The landscape here is stark and mineral, treeless, typical of the highest reaches of the Pyrenees. How do you get there? The starting point is the car park at the Cavallers dam, at 1,697 metres. From there, the trail climbs through the Barranc de Comalesbienes gully, with the ascent alone taking around four hours. The path is rocky and demanding, with little shade along most of the way, so an early start and plenty of water are essential. This is a route for hikers with mountain experience and solid fitness, not a casual afternoon walk. What will you see once you're up there? Two distinct peaks tower over the lake: Punta Alta (3,014 m) and Pic de Contraix (2,957 m), both serving as natural landmarks in this part of the massif. Right next door lies another glacial lake, Estanys de Comalesbienes, which makes it easy to combine both into a single, longer trek. The water itself, ringed by granite blocks and scree, sits in sharp contrast to the surrounding ridgelines — on calm days the peaks mirror perfectly on its surface. When is the best time to visit? At nearly 2,750 metres, the lake stays frozen or snow-covered for most of the year. The most reliable window for hiking runs from July to September, when the trail is fully clear and snow has retreated from the upper valley. Outside those months it's worth checking current conditions, since snow cover at this altitude can linger into June and return again as early as September. Frequently asked questions Is the hike to Estany Gelat difficult? Yes — the climb from the Cavallers dam car park takes around four hours over steep, rocky terrain. It suits hikers with mountain experience rather than casual walkers. Are there other lakes nearby worth visiting? Yes, Estanys de Comalesbienes sits right next to it in the same gully, making it easy to plan a longer route combining both lakes in a single outing. Which peaks can you see from the lake? Punta Alta (3,014 m) and Pic de Contraix (2,957 m) rise above Estany Gelat, both serving as recognisable landmarks for hikers exploring this part of the massif. Is the lake inside a national park? Yes, Estany Gelat lies within the Aigüestortes i Estany de Sant Maurici National Park, one of the best-known protected areas in the Spanish Pyrenees.

Estany Gelat de Comaloforno
la Vall de Boí
Estany Gelat de Comaloforno is a high-mountain glacial lake in the municipality of la Vall de Boí, sitting inside the Aigüestortes i Estany de Sant Maurici National Park in the Alta Ribagorça comarca. The lake rests at roughly 2,683 metres above sea level, in the upper Caldes valley, northeast of Pic de Comaloforno and east of the Besiberri Sud massif. The Catalan word "gelat" means "frozen," a fitting name — for most of the year the lake stays locked under ice and snow, revealing its striking turquoise water only during a short summer window. How do you get there? Most routes start from the car park at the Cavallers Dam (Pantà de Cavallers, about 1,723 m), reached by road from Caldes de Boí. From there the trail climbs steeply through the Pas de l'Ós pass toward Coma les Torres before continuing on to Estany Gelat de Comaloforno. The hike demands solid fitness — the elevation gain approaches a thousand metres, and the final stretches are steep and exposed in places. This is not a walk for beginners, but experienced hikers cover it comfortably in a single day. What will you see? The lake sits in a stark, high-alpine setting, ringed by the rocky ridgelines of the Pyrenees. It's a classic glacial tarn — small, deep, and fed by melting snow and ice from the surrounding slopes. Nearby lie other lakes from the same group, including the Estanys de Gémena, which makes it easy to plan a longer circular route linking several bodies of water. For more ambitious hikers, Estany Gelat de Comaloforno also serves as a springboard for climbing Pic de Comaloforno or Besiberri Sud, both summits visible practically within arm's reach from the shore. Bring a camera: the contrast between the dark-blue water, patches of white snow, and grey rock makes for one of the more distinctive views in the entire park. When should you visit? The best window is summer, from July to September, when most of the snow has melted and the trails are passable without winter gear. Outside that period, the lake and surrounding passes can still be snowbound, which sharply raises both difficulty and risk. Start early in the day — weather in the high Pyrenees can turn abruptly by afternoon, and thunderstorms are common around peaks above 2,500 m during summer. Frequently asked questions Is the hike to the lake difficult? Yes. It's rated difficult due to its length, substantial elevation gain, and steep, partly exposed sections, especially around the Pas de l'Ós. Good physical condition and mountain hiking experience are required. Can you swim in the lake? The water in this glacial lake, sitting at nearly 2,700 m, stays very cold year-round, and swimming isn't practiced or recommended — it's primarily a scenic and route destination for hikers and climbers. How long does it take to reach the lake? From the Pantà de Cavallers car park, the one-way climb typically takes a few hours depending on fitness and the chosen route variant; a full-day round trip is the standard plan. Do you need a permit to enter the national park? Hiking on the trails of the Aigüestortes National Park is generally open to the public, though it's worth checking current rules on any seasonal entry limits for popular routes during summer.

Lagunas de San Martín
Valderrueda
Lagunas de San Martín is a group of three small lakes near the village of San Martín de Valdetuéjar, part of the municipality of Valderrueda in the eastern reaches of the Montaña Leonesa — the mountainous region of the province of León. Locals simply call them "las pozas" (the pools), and for years they were a quiet neighborhood secret before word spread among travelers, photographers, and nature lovers from León, Palencia, and even Asturias and Cantabria. Where did these lakes come from? The lagoons aren't a purely natural feature — they formed inside former mining pits in the Valdetuéjar Valley. Once extraction stopped, the abandoned workings filled with water, leaving behind three distinct pools. One of them is now too overgrown with fallen leaves to swim in comfortably, but the other two remain the main draw for visitors. What will you see there? One of the most noticeable traits of the water here is the sharp temperature contrast at different depths. Near the surface, in the first few meters, the water warms up surprisingly fast, but the deeper you go, the colder it gets — a typical effect in pools born from old mining excavations. The surroundings offer the classic scenery of the Montaña Oriental Leonesa: green slopes, quiet trails, and an intimate atmosphere far removed from the crowds of bigger resort towns. Beyond tourism, Lagunas de San Martín also serve a practical purpose: firefighting aircraft and helicopters have long drawn water from here to battle wildfires across the mountains of León and surrounding areas. It's a reminder that this modest lagoon plays a real role in the region well beyond the summer swimming season. How do you get there? The starting point is the village of San Martín de Valdetuéjar itself. Once in the village, head toward the left, in the direction of the local rural house (casa rural) and the village hermitage. From there, a path leads directly to the lagoons. The route is short and not particularly demanding, making it suitable for families with children and visitors with an average fitness level. Lagunas de San Martín sit roughly 3.5 kilometers from Puente Almuhey, the administrative capital of the Valderrueda municipality, making the site an easy day-trip destination. When should you visit? Summer is the best time to come, when high temperatures make swimming appealing and the surface water is at its most comfortable. This is also when the lagoons see their heaviest footfall, as visitors look for a cool escape away from the crowded coastal resorts. Keep in mind that the site's popularity has been growing year after year, so expect more company during peak season, especially on weekends. Frequently asked questions Can you swim at Lagunas de San Martín? Yes — two of the three lagoons are suitable for swimming. The third is too overgrown with fallen leaves for comfortable bathing. How far are the lagoons from the nearest larger town? They sit about 3.5 km from Puente Almuhey, the administrative capital of Valderrueda, and are within easy day-trip distance from León. Is the walk to the lagoons difficult? No. The path starts at the rural house and hermitage in San Martín de Valdetuéjar and is accessible to most visitors, including families with children. Why is the water so cold at depth? The lagoons formed inside former mining pits. The surface water warms quickly in the sun, but deeper down the water stays noticeably colder.

Lagunas de Montañana
Miranda de Ebro
Lagunas de Montañana is a cluster of lagoons formed in former gravel pits along the Ebro River, right next to the small village of Montañana, part of the municipality of Miranda de Ebro (Burgos province, Castile and León). Where is it and how do you get there? Montañana sits about 7 km north of downtown Miranda de Ebro, on the BU-735 road between the villages of Guinicio and Suzana. The settlement stretches along the bank of the Ebro River — the province of Álava begins right on the opposite shore. From Miranda de Ebro it's a short drive of a few minutes, and the route is also walkable or bikeable along local paths that follow the riverbank. How did the lagoons form? The lagoons, known locally as Lagunas de los Yelsos, formed in a meander of the Ebro on the site of old gravel quarries. Once extraction stopped, the pits gradually filled with water and became a network of calm, shallow lakes. It's a landscape typical of the Ebro valley: a post-industrial site that, over time, turned into a valuable wetland. What will you find there? Despite visible traces of past gravel extraction, the surrounding area has kept real ecological value. Patches of melojo oak woodland survive among the farmland, and lush riverside vegetation lines the banks of the Ebro. The lagoons and the adjoining river stretch make for good waterbird watching — the calm surface draws a good variety of species, which birdwatchers will appreciate. In the village itself, look out for the parish church of San Andrés, whose structure blends elements from the 13th to the 18th century, and a striking, centuries-old ash tree that serves as a local landmark. What trails run through the area? Montañana lies along the long-distance trail "Agua y Roca: Del Ebro a los Obarenes," roughly 60 km long, linking the Obarenes mountains with the Ebro valley between Pancorbo and Miranda de Ebro. The route also passes through neighboring Suzana and other small villages in the Miranda de Ebro district. The stretch along the right bank of the Ebro opens up wide views over the river valley and chances to spot local flora and fauna, from waterbirds to native riverside plants. It works well both for a short walk around the lagoons and for hikers tackling a longer section of the trail. When should you visit? Spring and autumn offer the best conditions for visiting and birdwatching, with mild temperatures and stable water levels in the lagoons. Summers in the Ebro valley can get hot, though the shade of riverside trees softens the heat along the walking routes. Winter is quieter, though several waterbird species stay in the area year-round. Frequently asked questions How far is it from Miranda de Ebro to the lagoons? About 7 km along the BU-735 road heading north, toward Guinicio and Suzana. Is it suitable for a walk with children? Yes, the ground around the lagoons is flat and easy to access, though care is needed close to the water's edge. Can you go birdwatching there? Yes, the calm waters of the lagoons attract waterbirds, making the site a popular spot among nature observers. What else is worth seeing in Montañana itself? The parish church of San Andrés (13th–18th century) and the distinctive, centuries-old ash tree in the village center.

Albufera de Anna
Anna
Albufera de Anna is a natural spring-fed lake sitting right next to the village of Anna, in the Canal de Navarrés region, roughly 70 km inland from Valencia. The lake stretches close to 300 metres in length and 180 metres across, fed by underground springs rising through the rocky ground. How do you get there? Anna sits inland in Valencia province, well away from the coast. Driving is by far the easiest option — from Valencia city the trip takes around an hour. The village itself is small, and the lake lies about a kilometre from the centre, reachable on foot or by bike along a clearly marked path. What will you see at the lake? An easy path circles the entire lake, flat enough for almost anyone to manage without difficulty. Along the way there are shaded viewpoints, benches and green picnic areas. The water is home to ducks, geese and other waterfowl, along with barbel and trout. Swimming directly in the lake itself is not permitted, but right beside it sits a natural pool fed by a small cascade tumbling over the rocks, and a municipal pool with lifeguards operates through the summer season, from late June until September. Since August 2024, boat rides have been running on the lake from Wednesday to Sunday, between 12:30 and 19:15. Half an hour costs five euros, with each boat carrying up to four people. Nearby stands El Laberinto del Lago, one of the largest hedge mazes in Europe, a popular stop for families travelling with children. Anna itself has more to offer beyond the water. The village name has Arabic roots and translates to "water", fitting given how many springs and fountains dot the surroundings, among them the Fuente de Santa María and the Balsa de Abajo. At the centre of town stands the Palace of the Counts of Cervellón, whose architecture has earned Anna the nickname "the Valencian Alhambra" — visiting the interior requires booking ahead through the local tourist office. The hermitage of Santísimo Cristo de la Providencia is also worth a stop. When is the best time to visit? Summer is the obvious choice for swimming and boat rides, though it also draws the largest crowds, especially on weekends. Spring and early autumn suit hikers better, with trails winding through nearby gorges and past waterfalls — temperatures are milder and the scenery just as striking. The site is well equipped for visitors: restrooms, restaurants and terrace bars, a children's playground and picnic tables scattered around the grounds. A campsite sits about 50 metres from the shore, making the lake a solid base for a longer stay in the area. Frequently asked questions Can you swim in Albufera de Anna? No, swimming in the lake itself is banned year-round. A natural pool fed by a cascade sits right next to it, along with a municipal pool open from late June through September. How much does a boat ride cost? Half an hour on the water costs five euros, with each boat holding up to four passengers. Rides run Wednesday through Sunday, from 12:30 to 19:15. How long does it take to walk around the lake? The loop trail is short and flat, usually taking no more than 30 to 40 minutes at a relaxed pace. What else is worth seeing in Anna besides the lake? The Palace of the Counts of Cervellón, known locally as the "Valencian Alhambra", the hermitage of Santísimo Cristo de la Providencia, and El Laberinto del Lago, a large hedge maze near the shore.

Estany d'Eixerola
la Torre de Cabdella
Estany d'Eixerola is a glacial lake in the municipality of la Torre de Cabdella, tucked into the Vall Fosca valley in the Lleida Pyrenees. Sitting at 2,351 metres above sea level, northeast of the village of Capdella, it lies within the peripheral zone of the Aigüestortes i Estany de Sant Maurici National Park. What will you find at the lake? Eixerola covers just under 7 hectares and stretches about 385 metres in length — one of the smaller lakes in this stretch of the Pyrenees, but no less scenic for it. Since the construction of the Estany de Cubieso dam, its waters have merged with the neighbouring reservoir, forming a single larger mountain basin ringed by rocky ridges and high-Pyrenean vegetation. The lake belongs to a remarkable network known as the estanys de Cabdella — twenty-seven glacial lakes linked by underground tunnels. The system dates back to the early 20th century (1911–1916), built alongside the Capdella hydroelectric power station. The lakes served a dual purpose: generating power and regulating water flow between reservoirs, with Estany Gento acting as the system's central hub. It's a rare case of century-old hydroelectric infrastructure woven directly into a high-mountain landscape. How do you get to Estany d'Eixerola? The village of Capdella, in the municipality of la Torre de Cabdella, is the natural starting point for exploring the area. From there, hiking trails connect the various lakes of the Cabdella system, with routes of varying difficulty popular among trekkers and mountain hikers. A cable car — the Vall Fosca cremallera — helps visitors reach the higher parts of the valley, leading toward Estany Gento, from where further hikes branch out to the surrounding lakes, Eixerola included. When is the best time to visit? The ideal window runs from June to October, when trails are clear of snow and weather conditions in the high Pyrenees are favourable for long hikes. Outside that period, snow at altitudes above 2,000 metres makes the approach routes considerably tougher. Who is this destination for? Given the altitude and the need to hike in (or take the cable car partway), Eixerola is best suited to visitors who enjoy high-mountain trekking and landscape photography. It also rewards anyone with an interest in industrial heritage — the combination of a natural lake with century-old hydroelectric infrastructure is an unusual pairing in the Pyrenees. Frequently asked questions Is Estany d'Eixerola a natural lake? Yes, it's a glacial lake, though its current shape and its merger with the neighbouring reservoir are the result of the Estany de Cubieso dam, built as part of the Cabdella hydroelectric system. How many lakes make up the Cabdella system? Twenty-seven lakes, connected by underground tunnels built for the Capdella hydroelectric power station between 1911 and 1916. Can you drive to the lake? Not directly — access is on foot via hiking trails from around Capdella, partly aided by the Vall Fosca cable car. Is the lake inside a national park? It lies within the peripheral zone of the Aigüestortes i Estany de Sant Maurici National Park, one of the most ecologically valuable areas of the Pyrenees.

Lagunas de Suzana
Miranda de Ebro
Lagunas de Suzana is a small group of lagoons near the village of Suzana, part of the municipality of Miranda de Ebro in the province of Burgos, just a few kilometers from the city center. The site has an unusual origin story: the ponds formed on the site of a former mining excavation that, once abandoned, gradually filled with water and turned into a natural wetland. How do you get there? The lagoons lie about 5 km from Miranda de Ebro, between the villages of Ayuelas and Suzana. The easiest way to reach them is by car along the local road connecting the city to these villages, then continuing the last stretch on foot or by bike — the terrain around the lagoons is flat and requires no special preparation. The spot is a popular destination for locals from Miranda de Ebro looking for a nature escape without traveling far. What will you see? The main draw here is birdlife. Since the old excavation site filled with water, the lagoon has been colonized by hundreds of species of waterbirds and migratory birds — grebes, cormorants, herons, storks, ducks, and coots have all been recorded here, alongside birds of prey and passage migrants stopping to rest or overwinter. The number of species recorded is notably higher than the average for surrounding areas, making Suzana one of the more interesting birdwatching spots in the region. It's worth knowing that in 2019 part of the lagoons suffered damage after being illegally filled with construction rubble, reducing the area's surface. The companies responsible were convicted by a court in Miranda de Ebro for environmental crimes. The episode is a reminder of how fragile — and valuable — this ecosystem is, and how important its protection remains; today the site continues to draw nature lovers and birdwatchers alike. When should you visit? The best time to visit is during bird migration seasons — spring and autumn — when the lagoons fill with passage species stopping to rest. Winter is also rewarding, as many waterbirds spend the cold months here. Summer tends to be quieter in terms of species diversity, but it's a pleasant time for a walk by the water with longer days and warmer weather. Who is it for? Lagunas de Suzana suits anyone looking for a peaceful nature spot close to the city — birdwatchers, nature photographers, cyclists, and casual walkers alike. It's also a compelling example of nature reclaiming land after industrial use, a backstory worth knowing before you go. Frequently asked questions Is there an entrance fee for the lagoons? No, it's an open natural area, free to visit for walkers and birdwatchers. How long does a visit take? Walking around the lagoons and birdwatching usually takes between 1 and 2 hours, depending on your pace and how many stops you make. Do you need special equipment for birdwatching? It's not required, but binoculars make it much easier to spot waterbirds and migratory species that keep their distance from the shore. Are the lagoons safe and accessible year-round? Yes, the site is accessible all year, though conditions and the variety of birds you'll see change with the seasons, especially during migration periods.

Estany de la Collada
la Vall de Boí
Estany de la Collada is a high-mountain glacial lake in the municipality of la Vall de Boí, in the Alta Ribagorça county, sitting inside the Aigüestortes i Estany de Sant Maurici National Park in the Catalan Pyrenees. Where exactly is Estany de la Collada? The lake sits at an altitude of 2,453 metres, in the side valley of Vall de Morrano, surrounded by the rocky, high-alpine terrain typical of this part of the park. Its outflow runs west, feeding the Barranc de Morrano stream. Nearby landmarks help with orientation: Pala de Morrano rises to the northwest, the Collada pass to the northeast, and the Pic de Dellui peak to the southeast. A smaller neighbouring pool, Estany Xic, lies a little further to the south-southeast. How big is the lake? Estany de la Collada is modest in scale compared with some of the park's better-known lakes: it covers roughly 1.6 hectares and reaches a maximum depth of about 15 metres. That size gives it a more intimate feel than the broad estanys found deeper in the park's core, while still showing the clear water and rocky shoreline typical of glacial lakes at this altitude. Can you hike there? The lake sits along a route that links several high-altitude lakes in this part of Vall de Boí — trails through the Vall de Morrano area make it possible to visit Estany de la Collada together with neighbouring lakes such as the estanys de Delluí in a single outing. Given the altitude (over 2,400 metres) and rocky ground, reaching it calls for reasonable fitness and proper trekking footwear: this is mountain terrain, with uneven paths and the changeable weather typical of the high Pyrenees. Why visit this particular lake? For anyone planning a hike through the Aigüestortes i Estany de Sant Maurici National Park, Estany de la Collada offers a quieter alternative to the park's most famous lakes. It shows the same glacial scenery that defines the area, but with far fewer visitors along the way. The surrounding ridges and mountain pass frame a landscape characteristic of the highest reaches of the Catalan Pyrenees. Frequently Asked Questions How high up is Estany de la Collada? The lake lies at 2,453 metres above sea level, in the Vall de Morrano. How large is the lake? It covers about 1.6 hectares and reaches a maximum depth of roughly 15 metres. Which national park is it part of? Estany de la Collada lies within the Aigüestortes i Estany de Sant Maurici National Park, in the municipality of la Vall de Boí. Are there other lakes nearby? Yes — the same valley and trail also lead to Estany Xic and the estanys de Delluí, making it possible to plan a longer route covering several lakes in one trip.

Lagunas de Valcabadillo
Tubilla del Lago
Lagunas de Valcabadillo is a small cluster of three restored lagoons in the municipality of Tubilla del Lago, in the province of Burgos, right in the middle of the Ribera del Duero wine region in Castilla y León. What exactly is this place? The site is made up of three water basins of different sizes, covering roughly 23,000 m² in total. The water is shallow throughout, with an average depth of about 1.5 metres, though some spots go deeper. The land itself sits on an old calcareous peat bog that had dried out over the years as farmers drained it for agricultural use, eventually disappearing as a wetland altogether. Why "restored" and not just "natural"? What looks like an untouched natural landscape today is actually the result of a targeted restoration project. Work to bring the water back to this site started in mid-August 2007 and wrapped up about a month later, with a total investment of 350,000 euros. The goal was straightforward: recover a wetland that had vanished due to agricultural drainage, returning the area to something closer to what it once was before it was drained and farmed. What kind of wildlife lives here? Lagunas de Valcabadillo now functions as a designated bird-watching area. The reconstructed basins act as a refuge for waterfowl and amphibians, species that had lost this habitat once the original wetland dried up decades earlier. That's the main draw for visitors who come specifically to watch birds, even though the lagoons themselves cover a fairly small area. How do you get there, and what is the Gromejón trail? The lagoons mark the end point of a walking trail that follows the Gromejón river. The route starts in Tubilla del Lago, passes through Villalbilla de Gumiel, and finishes at the lagoons after close to 14 km on foot. It's a genuine hiking option for anyone planning a longer walk in the area, not just a quick roadside stop. The site itself is wheelchair accessible, with an adapted entrance and accessible parking. It's open around the clock, every day of the week, and there's no admission charge. The paths around the lagoons are easy and manageable with children, so no special fitness or gear is needed for a visit. Is it worth a stop? Visitors describe the spot as quiet and rarely crowded, with a decent view over the water and the surrounding farmland. This isn't a full-day destination, but it's a solid short break on a Ribera del Duero itinerary, especially for anyone interested in waterbirds or simply looking for some quiet away from busier tourist spots. Frequently Asked Questions Is there an entrance fee for Lagunas de Valcabadillo? No, access is free and the site is open 24 hours a day, every day of the week. Are the lagoons a natural feature? Not entirely — this is a reconstructed wetland. The area had dried out over the years due to agricultural drainage, and the water was brought back in 2007 as part of a restoration project. Can you walk to the lagoons from Tubilla del Lago? Yes. The lagoons sit at the end of a trail along the Gromejón river that starts in Tubilla del Lago and runs roughly 14 km one way through Villalbilla de Gumiel. Is the site accessible for wheelchair users? Yes, both the entrance and the parking area are adapted for visitors with reduced mobility.

Fuentes Blancas wetland
Burgos
Fuentes Blancas wetland sits inside Fuentes Blancas park on the eastern edge of Burgos, roughly 6 km from the city centre, where the small Pico stream meets the Arlanzón river. Where the wetland sits The wetland occupies the eastern fringe of the city, within the larger Fuentes Blancas park that runs along the Arlanzón riverbank. The N-120 road borders it on one side and the northern motorway on the other, yet the site still reads as a quiet green pocket rather than a roadside strip — an easy walk or bike ride without leaving the city limits. History and the recent restoration The wetland began life as an old meander of the Arlanzón that dried out once nearby road works cut it off from the river. Efforts to bring it back as a flooded habitat started in 2002, with paths, bird-watching hides, and a perimeter fence added to keep visitors from disturbing the plants and animals. More recently, the city of Burgos carried out a further round of works: a new channel now links the wetland directly to the main Arlanzón channel, giving it a steady water supply instead of relying only on rainfall or occasional high river levels. Wildlife and birdwatching Vegetation around the water follows a typical riverside pattern — poplar, willow, ash, and alder mix with pine and juniper on the drier ground, while reeds, rushes, and bulrush line the water's edge. With more than 30 hectares of water and vegetation, the site draws waterbirds and wading species, making it one of the better birdwatching spots near the city, particularly from the marked observation points set back from the water. What else Fuentes Blancas park offers The name Fuentes Blancas comes from the natural springs scattered across the site, among them Prior, Salud, and Los Castaños. The wetland is only one part of a much larger green area that forms part of the belt of parkland ringing Burgos. Beyond the water, the park has a man-made river beach, a large children's playground, picnic and barbecue spots, a cycling path, and a campsite with a swimming pool. That mix pulls in both families planning a full day out and visitors who just want to walk the wetland trails. Frequently Asked Questions How far is the Fuentes Blancas wetland from central Burgos? About 6 km, on the eastern edge of the city along the Arlanzón riverbank — a short drive or a ride along the marked cycle path. Is it worth a special trip for birdwatching? Yes. The site covers more than 30 hectares of water and riverside habitat, and the marked observation points let you watch waterbirds without disturbing them. Where does the name Fuentes Blancas come from? From the natural springs found on site, including Prior, Salud, and Los Castaños, which gave the whole park its name. Is there anything for children beyond the wetland itself? Yes — the wider park has a large playground, a river beach, picnic and barbecue areas, and a campsite with a pool, so a visit can easily fill a whole day rather than just a walk around the water.

Lagunas del Raso de Portillo
La Pedraja de Portillo
Lagunas del Raso de Portillo is a wetland area in the municipality of La Pedraja de Portillo, in the province of Valladolid, Castile and León. Where are the lagoons and how do you get there? The site lies roughly 2 km from the centre of La Pedraja de Portillo, on the boundary with the municipality of Aldeamayor de San Martín, in a spot known locally as Dehesa de los Caballeros. Road signs at the entrance to town point the way to a parking area, from which several wide, unpaved paths lead on to a series of observation points. The route runs as a loop and is described as suitable for walking, cycling, and wheelchair use. How did these lagoons come to exist? The whole Raso de Portillo plain, once close to 1,900 hectares of open wetland, was drained between 1870 and 1873 through a 12-kilometre main channel carrying water to the river Cega, plus eight secondary channels adding up to 18 km. The drainage was meant to open up land for farming and reduce malaria in the area. The three small lagoons visible today - covering roughly 8, 2.8, and 0.7 hectares - are the result of restoration work carried out since 2012 by the Confederación Hidrográfica del Duero, the authority responsible for the Duero river basin, under its second river-bank restoration plan. The same body still manages the site. The lagoons sit on either side of the Arroyo del Molino, a tributary of the Cega, surrounded by dryland crop fields. What birds can be seen here? The combination of open water and steppe farmland makes the site popular with birdwatchers. Recorded species include great bustard, white stork, black-winged stilt, herons, coot, buzzard, teal, marsh harrier, red-legged partridge, plover, lapwing, bee-eater, and avocet, along with occasional sightings of Spanish imperial eagle, little grebe, mallard, shoveler, and gadwall. Six hides connected by a footpath let visitors watch the birds without disturbing them. When is the best time to visit? The lagoons can be visited year-round, though autumn and winter bring the highest numbers of waterbirds, when migrating and wintering species settle on the water. Spring and autumn migration windows also raise the odds of spotting less common species. The terrain is flat, open, and largely without shade, so binoculars or a spotting scope and some sun protection are worth bringing - the water can be some distance from the paths. Frequently Asked Questions How do you get to Lagunas del Raso de Portillo? The route is signposted from the entrance to La Pedraja de Portillo. A car park sits by the lagoons, about 2 km from the town centre, with a path leading on to the observation points. Are the lagoons natural? Not entirely - the area was a historic wetland drained in the 19th century, and the current lagoons were created through restoration work carried out from 2012 onward. Is the trail wheelchair accessible? Yes, the paths are wide and unpaved, and are described as suitable for walking, cycling, and wheelchair use. What birds are most typical of this site? Steppe species such as great bustard in the surrounding fields, and on the water itself coots, herons, ducks, and waders depending on the season.
