estany de Fonguera
Espot
Estany de Fonguera is a small glacial lake located in the municipality of Espot, in the Pallars Sobirà region of Catalonia. Where is estany de Fonguera located? The lake sits at an altitude of 2,544 metres, within the Aigüestortes i Estany de Sant Maurici National Park, in the Peguera Valley (Vall de Peguera). The basin stretches on an east-west axis, flanked by Pic de Fonguera (2,885 m) to the west and Pui de Linya (2,870 m) to the north. Its approximate coordinates are 42.5585°N, 1.0434°E. How big is the lake? Estany de Fonguera counts among the smaller high-mountain lakes in the area. Its surface covers roughly 1.35 hectares, the shoreline runs for about 737 metres, and the maximum length and width reach 282 and 120 metres respectively. The basin was carved by glacial activity, and the surrounding bedrock is granodiorite, a rock type common throughout this part of the Pyrenees. Where does the water come from and where does it go? The lake is fed by runoff descending from the higher Clotets del Pui. Its outflow follows the Barranc de Fonguera stream down to Estany de Lladres, after which the water continues through the Riu de Peguera, the Riu Escrita and the Noguera Pallaresa before joining the Segre, a tributary of the Ebro. This chain of connections places estany de Fonguera within a wider network of lakes and streams that drains the Peguera Valley. How do you get there? The surroundings of estany de Fonguera are high-mountain terrain, reachable on foot via trails running through the Aigüestortes i Estany de Sant Maurici National Park. One documented route links Prat de Pierró to Espot, passing estany de Monestero, estany de la Llastra and estany de Lladres along the way; it covers around 22.7 km and takes roughly 7 hours in total, with a cumulative ascent of 1,370 m and a descent of 1,698 m. Given the altitude and terrain, a trip into this part of the mountains calls for solid physical preparation, proper footwear, and a check on weather conditions before setting out, especially outside the summer months. What should you know before visiting? Estany de Fonguera lies within a protected area, so national park rules apply: hikers must stick to marked trails, wildlife and vegetation are protected, and there is no tourist infrastructure right at the lake itself — no shelters or food stops nearby. This is a destination for travellers looking for genuine contact with the wild high-mountain landscape of the Pyrenees rather than an easily accessible attraction. Frequently Asked Questions At what altitude is estany de Fonguera located? The lake sits at 2,544 metres above sea level. Is estany de Fonguera inside a national park? Yes, it lies within the Aigüestortes i Estany de Sant Maurici National Park, in the Peguera Valley. How large is the lake? It covers about 1.35 hectares, with a maximum length of 282 metres and a maximum width of 120 metres. How can you reach the lake? Access is on foot via mountain trails through the national park; one route connects Prat de Pierró to Espot through nearby lakes and takes around 7 hours in total.

Lagoa de Caque
Castro de Rei
Lagoa de Caque is a protected wetland reserve in the municipality of Castro de Rei, in the province of Lugo, in the Terra Chá region of Galicia. Located in the parish of Ribeiras de Lea, roughly 20 km from the city of Lugo, it is the largest wetland in the entire Terra Chá — a name that literally means "flat land," describing the terrain that shaped this lagoon. How did this lagoon form? Terra Chá is an unusually flat region with very little drop in elevation. Rivers here move slowly, and water easily spreads across the low-lying, poorly drained ground. These geological and topographic conditions gave rise to Lagoa de Caque, a natural basin covering close to 19 hectares. Locally the site is also known as Lagoa de Bardancos. What is there to see? The vegetation surrounding the lagoon is rich and varied: water lilies and rushes grow in and along the water, while further from the shoreline you'll find alders, willows, birches, oaks, and, in smaller numbers, pines. This mosaic of habitats supports more than a hundred protected species of plants and animals within a relatively small area. Above all, Lagoa de Caque is an important wintering ground for birds arriving from northern Europe. Visitors can spot several duck species, coots, and herons, making it one of the best birdwatching spots in the whole province of Lugo. Beyond birds, the lagoon is also home to numerous reptiles and amphibians, for which the wetland provides a natural refuge. What about access? Conservation is the priority here, so access to the lagoon itself is restricted — there is no marked path or trail circling the water, a deliberate choice to shield the ecosystem from excessive human disturbance. You can drive on a paved road to a point roughly 200 meters from the lagoon, after which the way continues on foot or along a dirt track. This setup lets visitors observe the wildlife from a respectful distance without disrupting it. Who is this destination for? Lagoa de Caque appeals mainly to birdwatchers and to anyone drawn to Galicia's quieter, unspoiled landscapes. Don't expect built-up tourist infrastructure — there are no restaurants or viewing platforms right at the reserve — but the surrounding villages of Terra Chá offer local food options and fishing opportunities on nearby rivers. Bringing binoculars is worthwhile if birdwatching is the goal, especially in winter, when the number of migratory species passing through is at its highest. Frequently Asked Questions Where exactly is Lagoa de Caque located? In the parish of Ribeiras de Lea, in the municipality of Castro de Rei, province of Lugo, about 20 km from the city of Lugo. Can visitors walk right up to the lagoon? Access is restricted for conservation reasons — there's no official path around the water. You can drive to within about 200 meters, then continue on foot along a dirt track. When is the best time to visit? Winter is the best season for birdwatching, since the lagoon serves as a wintering site for bird species arriving from northern Europe. Are there tourist facilities nearby? There's no infrastructure right at the reserve itself, but nearby villages in Terra Chá offer local dining options and fishing opportunities.

estany de Durro
la Vall de Boí
Estany de Durro is a small mountain lake in the municipality of la Vall de Boí, in the Alta Ribagorça county of the Catalan Pyrenees. Where is estany de Durro located? The lake sits at an altitude of over 2,200 metres, in the high-mountain section of the Vall de Boí valley. It covers a small area of roughly 2 hectares, making it a typical Pyrenean glacial lake set in a rugged, rocky high-mountain landscape. Its approximate coordinates are 42.4613°N, 0.8499°E. Vall de Boí is best known to visitors for two things: its proximity to the Aigüestortes i Estany de Sant Maurici National Park and its cluster of Romanesque churches, several of which are part of a UNESCO World Heritage Site. Estany de Durro lies in the same high-altitude zone, close to the edge of the park, although the lake itself is not the valley's most visited landmark. How do you reach the lake? A hiking trail leads to estany de Durro through the upper reaches of the valley. One route approaches from Ginebrell, while another reaches the lake on the way down from Corronco. Given the altitude — over 2,200 metres — and the exposed terrain, this is a route for hikers who come prepared with proper footwear, water, and route-finding skills, not a short walk from a car park. The village of Durro, which gives the lake its name, is the usual starting point for most hikers. The village itself sits lower down, at the foot of the valley's high-mountain section, and the trails climbing up to the lake begin from there. What should you know before setting out? Estany de Durro is one of many small lakes scattered across the high-altitude Catalan Pyrenees — a region known for glacial lakes both inside and around the Aigüestortes i Estany de Sant Maurici National Park. Compared with the park's better-known lakes, estany de Durro is a quieter, less-visited spot, appreciated by hikers looking for solitude rather than crowds. Weather in this part of the Pyrenees can change quickly, and the trail crosses open, high-mountain terrain with little shelter from wind or rain. Building extra time into the plan and checking the forecast before setting out matters more here than on lower-altitude routes. What else is worth seeing nearby? The village of Durro and the wider Vall de Boí valley serve as a base for visiting the region's Romanesque churches, one of the main cultural draws of Alta Ribagorça. For hikers, the valley is also a natural gateway to the Aigüestortes i Estany de Sant Maurici National Park, one of the most highly regarded mountain areas in the Pyrenees. Frequently Asked Questions How high up is estany de Durro? The lake lies at an altitude of over 2,200 metres, in the high-mountain part of the Vall de Boí valley. How big is the lake? Estany de Durro covers around 2 hectares — a small, typical Pyrenean glacial lake. How do you get to estany de Durro? Hiking trails through the upper valley lead to it, including routes from Ginebrell and one that passes it on the descent from Corronco; the village of Durro is the usual starting point. Is the route suitable for beginners? Because of the altitude and exposed high-mountain terrain, the route calls for preparation — proper footwear, a weather check beforehand, and some hiking experience.

estanh dera Solana
Vielha e Mijaran
Estanh dera Solana is a small mountain lake in the municipality of Vielha e Mijaran, in Catalonia's Aran Valley (Val d'Aran). It sits at roughly 2,085 metres above sea level, in the Salient stream valley, above the villages of Vilac and Vielha. Where exactly is this lake? Estanh dera Solana lies in the upper part of the Salient valley, surrounded by open alpine meadows and gently rolling terrain. The slopes above are dominated by Tuc de Guilèm (2,401 m), visible from the area around the lake. In the local Pyrenean languages, "solana" refers to a sun-facing, well-lit spot — and indeed the lake occupies an open basin rather than a shaded hollow, with no dense tree cover nearby. The lake itself is tiny — its surface area is only about 0.2 hectares, so this is closer to a mountain tarn than a large body of water. Despite its modest size, the calm water and open surroundings give it a distinct character as a stop on a hike through the Aran Valley's high meadows. How do you get to Estanh dera Solana? The usual starting point is the Pista de Salient track, at around 2,150 metres of elevation. From there, the Eth Coret de Mont trail leads toward the lake. This stretch is described as an easy walk within the lower part of the massif — it doesn't call for technical mountaineering gear or extensive experience, though as with any hike above 2,000 metres in the Pyrenees, proper footwear and a check on the weather forecast beforehand are worth the effort. Because the lake sits above 2,000 metres, visiting makes the most sense in summer, once the trails are clear of snow. In spring, late autumn, and especially winter, snow can still cover the surrounding meadows well into the season. What else is nearby? Estanh dera Solana isn't the only body of water in this part of the valley. Nearby are other small mountain lakes — Estanh de Gards and Estanh de Vilac — which makes it possible to plan a longer hike linking several lakes and viewpoints in a single outing. This kind of landscape, scattered with small glacial lakes among meadows and rocky ridges, is typical of the higher reaches of the Val d'Aran. The Arriu de Salient valley, where the lake sits, is close to Vielha, the capital of both the municipality and the wider Aran Valley, making the area a fairly accessible base for anyone staying in the region for a few days. Frequently Asked Questions How high up is Estanh dera Solana? The lake sits at approximately 2,085 metres above sea level, in the upper part of the Salient stream valley. How big is the lake? It's a very small body of water — around 0.2 hectares — considerably smaller than the well-known tourist lakes of the Pyrenees. Where does the trail to the lake start? The hike begins at the Pista de Salient track, at roughly 2,150 metres, following the Eth Coret de Mont trail on an easy stretch through the lower part of the massif. Are there other lakes nearby worth combining into the same hike? Yes — Estanh de Gards and Estanh de Vilac are both close by, allowing you to plan a route that takes in several mountain lakes across the high meadows of the Aran Valley.

estany xic de la Mainera
Sort
Estany Xic de la Mainera is a small mountain lake in the municipality of Sort, in the Pallars Sobirà region of the Catalan Pyrenees. It sits near the Aigüestortes i Estany de Sant Maurici area, at an altitude above 2,400 metres, within the Cresta de la Mainera ridge. Where is the lake located? The lake lies in the high-mountain section of the Vall d'Àssua, a valley belonging administratively to the municipality of Sort. The nearest starting point is the village of Llessui, from which trails climb into the mountains toward Clot de la Mainera and on to both Mainera lakes. The Catalan word "xic" means "small" — and indeed this lake is noticeably smaller than its neighbour, Estany Gran de la Mainera, which sits higher up along the same route. How do you get to the lake? The hike begins in the village of Llessui. The route passes through Clot de la Mainera, where the path follows a stream upstream — first reaching the larger of the two lakes, Estany Gran, then descending to the smaller Estany Xic. It's a typical high-Pyrenean trail: rocky, crossing pastureland and rocky terrain, requiring good fitness and proper footwear. It's worth checking current conditions before setting out, since snow can linger in the higher sections well into the season. What is there to see? Both Mainera lakes sit in a landscape typical of the high Pyrenees — bare granite ridges, rocky glacial cirques, and wide views over the surrounding peaks. Despite its modest size, Estany Xic retains the character of a wild, secluded glacial tarn, ringed by stony slopes. This is a destination for visitors seeking quiet and raw mountain scenery rather than tourist infrastructure — there are no food stalls or commercial markers in the immediate area. When is the best time to visit? Given the altitude, the comfortable hiking season here runs essentially from summer into early autumn, once the trails are clear of snow and passable. In spring and late autumn the route can be harder going or temporarily blocked by snow on the higher stretches. Frequently Asked Questions Is Estany Xic de la Mainera inside a national park? The lake sits right next to the Aigüestortes i Estany de Sant Maurici area, within the Mainera mountain range, a landscape typical of this Pyrenean national park. Where is the best starting point for the hike? The trail starts in the village of Llessui in the Vall d'Àssua, running through Clot de la Mainera to both lakes — first the larger Estany Gran, then the smaller Estany Xic. Is the route suitable for beginners? This is a high-mountain walking trail that requires reasonable fitness and proper preparation — it's not an easy, family-friendly path, but a typical Pyrenean mountain hike. What's the difference between Estany Xic and Estany Gran de la Mainera? Estany Xic is the smaller of the two Mainera lakes — "xic" means "small" in Catalan, in contrast to the neighbouring, larger Estany Gran.

estany gran de la Mainera
Sort
Estany Gran de la Mainera is a small glacial lake in the municipality of Sort, in the Pallars Sobirà region of Catalonia (Lleida province). It sits at roughly 2,450 metres above sea level, on the Cresta de l'Avió ridge, near the village of Llessui. Where exactly is this lake located? The lake lies in the Catalan Pyrenees, inside the peripheral zone of the Aigüestortes i Estany de Sant Maurici National Park. That setting explains the rugged, high-mountain feel of the surroundings — bare ridges, sparse vegetation and the quiet typical of this altitude. Its coordinates, 42.523889, 1.044722, make it easy to place on hiking maps of the area. Is there more than one lake up there? Yes. Estany Gran de la Mainera has a smaller neighbor, Estany Xic de la Mainera (literally "Small Lake of Mainera"). Together the two are known locally as the estanys de Mainera and form a popular hiking destination in this part of Pallars Sobirà. The usual loop starts from a spot called Clot de la Mainera, climbing first to the larger lake before passing the smaller one on the way down. How do you get there, and when is the best time to go? Most hikers set out from around Llessui, a village within the Sort municipality. The final stretch of trail runs through open, treeless high-mountain terrain, so proper footwear and layered clothing are worth packing even in summer. The route is generally passable year-round, except during winter and early spring, when snow still lingers above 2,400 metres — reaching the lake in those conditions calls for mountain experience and the right gear. Does the area have any cultural significance? The Mainera lakes are cited as the inspiration behind the Catalan novel "Verd Madur" by Josep Virós, which was later adapted for the screen. That gives the area an extra pull beyond hiking — it draws people curious about the literary and cultural history of Pallars Sobirà as well. What should you know before setting out? Given the altitude (above 2,400 metres) and the exposed terrain, it pays to check the forecast before leaving — Pyrenean storms can build quickly in the afternoon. There is no tourist infrastructure right at the lake itself — no food stalls or marked parking near the water — so it's best to stock up on water and food beforehand in Sort or Llessui. Frequently Asked Questions How high up is Estany Gran de la Mainera? The lake sits at around 2,450 metres above sea level, on the Cresta de l'Avió ridge. Are there other lakes nearby worth visiting? Yes, the smaller Estany Xic de la Mainera lies close by — together they form the popular hiking route known as the estanys de Mainera. Where's the best starting point for the hike? Most people start near the village of Llessui, in the Sort municipality, with the trail passing through Clot de la Mainera. Is the trail open all year? It's generally passable year-round, but snow lingering above 2,400 metres makes winter and early-spring access harder.

Estanh des Trueites
Vielha e Mijaran
Estanh des Trueites is a small glacial tarn in the municipality of Vielha e Mijaran, in the Val d'Aran valley of the Spanish Pyrenees. Sitting at roughly 2,307 metres above sea level, its Aranese name translates to "trout lake" — trueites being the local word for trout. Where is Estanh des Trueites located? The lake sits high in the Pales dera Pincèla massif, surrounded by rocky ridges and alpine meadows. Its coordinates are approximately 42.7458°N, 0.8692°E. The tarn itself is modest in size, measuring around 115 metres in length and 98 metres across, giving it a surface area of roughly 0.9 hectares. It is a classic Pyrenean estanh — a high-altitude pool carved out by glacial action in a rocky basin. How do you reach the lake? Starting from Bagergue The most common starting point is Bagergue, one of the highest villages in Val d'Aran. From the village, a track heads toward Santa Margalida and then on to Era Borda Era Lana, where it joins the Varradòs route. After parking, hikers follow a marked path up the slope of Pales dera Pincèla, passing smaller ponds and winter-route markers along the way. The path runs alongside the Pincèla stream, with the final stretch climbing steeply right beside the watercourse before opening onto the lake. From the parking area, the walk up typically takes around one hour and ten minutes. The route is rated medium difficulty — no technical gear is required, but the steep section beside the stream calls for reasonable fitness and sure footing on loose rock. What else is worth seeing nearby? The area around the lake offers views of Maubèrme, one of the recognisable peaks in this stretch of the Pyrenees. A short distance further, and higher up than Estanh des Trueites, sits a second, smaller pool: Estanh dera Pincèla. Hikers who want to extend the walk can push on to the summit of Tuc dera Pincèla, which rises above 2,500 metres. From the top, across alpine pastures, the panorama takes in Aneto and Maladeta, Maubèrme, the Val d'Unhòla valley, and Val d'Aran spread out below. Who is this route suited for? This is a hike for people used to high-mountain terrain — the ground is rocky and the final approach to the lake is steep. It is not a route for families with young children, but experienced Pyrenean hikers should manage it comfortably in a few hours round trip, longer if the summit is included. Frequently Asked Questions How high up is Estanh des Trueites? The lake sits at roughly 2,307 metres above sea level, in the high-mountain section of Val d'Aran. Where's the best place to start the hike? Most hikers begin in the village of Bagergue, following the track through Era Borda Era Lana and the Varradòs route toward Pales dera Pincèla. How long does it take to reach the lake? From the parking area, the climb takes about one hour and ten minutes, mostly along a steep stretch beside the Pincèla stream. Is there anything else to see nearby? Above Estanh des Trueites lies a second, smaller pool called Estanh dera Pincèla, and the trail can be extended all the way to the summit of Tuc dera Pincèla for views of Maubèrme and Maladeta.

estanyets de Dellui
la Vall de Boí
Estanyets de Dellui is a cluster of small glacial lakes in the municipality of la Vall de Boí, high in the Catalan Pyrenees, inside Aigüestortes i Estany de Sant Maurici National Park. Sitting above 2,300 meters, the lakes are one of many quiet, less-visited stops along the high-mountain hiking routes that crisscross this part of the park. Where exactly are the Estanyets de Dellui? The lakes lie in the Alta Ribagorça comarca, just below the larger Estany de Dellui, at an elevation of roughly 2,308 to 2,324 meters. They drain toward the north-northwest into the Barranc de Dellui stream. The whole area sits within Aigüestortes i Estany de Sant Maurici National Park, one of Catalonia's best-known high-mountain regions, where glacial lakes and valleys are the main draw for visitors. How do you get there? There's no road access to Estanyets de Dellui — the only way in is on foot, along mountain trails that lead deep into the park. One common approach starts at Planell d'Aigüestortes, heading toward Estany Llong and then up the Barranc de Dellui valley. A second option starts at Refugi d'Estany Llong and follows the path via Corticelles. Both routes cross the kind of terrain the park is known for: high meadows, rock, and a scatter of glacial lakes. Is the hike difficult? Routes through the Dellui valley rank among the more demanding in the area — one popular loop nearby covers around 13 kilometers and takes roughly 4.5 hours. The terrain sits above 2,000 meters throughout, so a reasonable level of fitness, proper footwear, and awareness of the fast-changing weather typical of the high Pyrenees are all worth planning for. When is the best time to visit? The hiking season around Estanyets de Dellui generally runs from June to October — outside that window, the high trails are often snow-covered or hard to access. Snow can still linger at higher elevations in June and July, while September and early October tend to bring more stable weather and fewer hikers on the trails. What should you know before setting out? Estanyets de Dellui sits deep inside the national park, in an area with no tourist infrastructure — there are no food stops or marked parking areas right by the lakes themselves. The nearest support point for hikers is Refugi d'Estany Llong, from which the final approach can be planned. Given the altitude and terrain, it's worth mapping the route in advance, carrying a proper map, and checking current park conditions before heading up toward the Dellui valley. Frequently Asked Questions What are the Estanyets de Dellui? They are small glacial lakes in the municipality of la Vall de Boí, inside Aigüestortes i Estany de Sant Maurici National Park, sitting above 2,300 meters elevation. How do you reach the Estanyets de Dellui? Only on foot — typically from Planell d'Aigüestortes via Estany Llong and the Barranc de Dellui valley, or from Refugi d'Estany Llong along the Corticelles path. When is the best time to hike this area? Between June and October, with the most stable conditions usually found in September and early October. Is there any tourist infrastructure near the lakes? No, there's nothing directly at the lakes — the nearest support point is Refugi d'Estany Llong, from which trails continue further into the valley.

Bassa de les Granotes
Espot
Bassa de les Granotes is a small glacial lake in the municipality of Espot, within the Aigüestortes i Estany de Sant Maurici National Park in the Catalan Pyrenees. The western edge of the lake actually crosses into the neighbouring municipality of Vall de Boí, in Alta Ribagorça, placing the water right on the boundary between two Pyrenean valleys. Where exactly is this lake? The lake sits at an altitude of 2,324 metres, on the upper right bank of the Barranc de Peixerani stream, at the foot of the southwestern end of the Portarró d'Espot pass. From that pass the water drains westward, feeding the stream network further down the valley. The lake covers roughly 0.74 hectares and stretches about 140 metres in length — a modest size, but typical of the high-altitude glacial tarns scattered across this part of the Pyrenees. Why is it called the "frog pond"? The Catalan word "granotes" means frogs, so the name loosely translates as the pond or lake of the frogs. Naming small Pyrenean lakes after the wildlife found around them is a common local pattern — many nearby tarns carry names describing their appearance, setting, or the animals associated with them rather than a person or historical event. How do you get to Bassa de les Granotes? The lake lies deep inside the national park, surrounded by the rocky ridgelines, alpine meadows, and cluster of glacial lakes that define the Aigüestortes massif. Access is via hiking trails that pass near the Portarró d'Espot pass, and reaching the lake means walking well above 2,300 metres, so a reasonable level of fitness and proper hiking gear are needed. Because conditions at this altitude can shift with the season, it is worth checking current trail status at the national park's information point in Espot before setting out. What else is there to see nearby? The area around Bassa de les Granotes forms part of the wider network of glacial lakes inside Aigüestortes, one of Catalonia's most highly regarded mountain areas. Nearby, hikers pass other small tarns and viewpoints looking down over the Peixerani valley and the ridges surrounding the Portarró pass. This is a spot for travellers seeking quiet, high-mountain scenery rather than tourist infrastructure — the national park enforces the usual access and overnight-stay restrictions found in protected areas. Frequently Asked Questions How high up is Bassa de les Granotes? The lake sits at 2,324 metres above sea level, inside the Aigüestortes i Estany de Sant Maurici National Park. How big is the lake? It covers around 0.74 hectares and measures about 140 metres in length, making it a small glacial lake. Which municipality is the lake in? Mostly in Espot (Pallars Sobirà), though its western edge extends into the municipality of Vall de Boí in Alta Ribagorça. Can you reach the lake without mountain hiking experience? Since it sits above 2,300 metres deep inside the national park, the walk calls for decent fitness and proper footwear; checking the route with the park's information point beforehand is a good idea.

Estanys dels Gavatxos
Espot
Estanys dels Gavatxos are a pair of high-mountain glacial lakes straddling the border between the municipalities of Espot (Pallars Sobirà) and La Vall de Boí (Alta Ribagorça), deep inside the Aigüestortes i Estany de Sant Maurici National Park. The northern lake sits on the Espot side, the southern (upper) lake on the Vall de Boí side, separated by little more than a saddle and a few hundred metres. Where exactly are the Gavatxos lakes? Both lakes lie in the upper reaches of the Coma dels Pescadors valley, above 2,500 metres. The northern lake sits at roughly 2,549 m, the southern one at roughly 2,561 m. The setting is classic high Pyrenean terrain: bare granite outcrops, sparse vegetation, and the intense blue water typical of glacial tarns at this altitude. How big are the lakes? The northern lake covers about 1.4 hectares and reaches a maximum depth of around 5.5 metres. The southern lake is similar in size. Small but surprisingly deep, both stay cold year-round — normal for tarns at this elevation in the central Pyrenees. How do you get to Estanys dels Gavatxos? The standard approach climbs to Collada dels Gavatxos, a pass that opens up views over both sides of the ridge at once. From the col, the trail drops through the wild Coma dels Pescadors valley toward the lakes. Many hikers link the route with the mountain refuges in the area — Refugi Colomina, the Collada dels Gavatxos pass, and Refugi Estany Llong — turning it into a longer multi-hour traverse rather than a there-and-back walk. Given the altitude and terrain — loose rock, no marked access road, no shortcuts — this is not a casual stroll. It calls for solid fitness, proper trekking boots, and some experience moving through high-mountain terrain. Why go out of your way for these lakes? Estanys dels Gavatxos combine two things that are hard to find together in Aigüestortes: relative solitude, since the crowds that gather around the more accessible lakes near valley trailheads rarely make it this far, and the payoff view from the col itself, where two adjoining valleys and two different municipalities come into view at once. It's a destination for hikers looking for something beyond the busiest spots around Estany de Sant Maurici. Frequently Asked Questions Are Estanys dels Gavatxos located in Espot? Partly. The northern lake lies within the municipality of Espot (Pallars Sobirà), while the southern, upper lake lies within La Vall de Boí (Alta Ribagorça). The Collada dels Gavatxos pass connects both sides. How high up are the lakes? The northern lake sits at about 2,549 m above sea level, and the southern one at about 2,561 m. Is the hike difficult? Yes — it's a high-mountain route over rocky terrain with no paved access paths. It requires good physical condition and appropriate footwear. Can the route be combined with mountain refuges? Yes. A popular variant runs via Refugi Colomina, over the Collada dels Gavatxos pass, and on to Refugi Estany Llong, making it possible to plan a longer multi-day route through the park.

estany Perdut
la Vall de Boí
Estany Perdut is a glacial lake in the municipality of la Vall de Boí, in the Catalan Pyrenees, within the Aigüestortes i Estany de Sant Maurici National Park. Where is Estany Perdut located? The lake sits at an altitude of roughly 2,461 metres, at the foot of the Tossal de la Montanyeta peak. This places it firmly in the high-mountain zone of the Catalan Pyrenees — open, rocky terrain above the tree line, surrounded by ridgelines. Its coordinates are 42.56025 N, 0.96780556 E. How did the lake form? Estany Perdut is a glacial lake, formed in a basin carved out by a retreating glacier that later filled with meltwater and precipitation. Lakes of this kind — locally called "estanys" — are the defining feature of the Aigüestortes area, where dozens of similar bodies of water are scattered across the park's high glacial cirques. Estany Perdut covers about 1.56 hectares and reaches a maximum depth of 26 metres, making it a relatively deep pool for its modest surface size. How does it connect to nearby lakes? Estany Perdut's drainage links it to Estany de la Coma d'Amitges, a neighbouring lake within the same cluster of glacial pools. This kind of interconnected chain of lakes and streams is typical throughout the park's interior: water cascades down from the higher cirques toward the Sant Nicolau valley, eventually feeding the rivers that drain the whole massif. Can you reach it on foot? Estany Perdut lies deep inside the protected core of the national park, in a zone that requires several hours of uphill walking from the lower valley to reach. Access to Aigüestortes i Estany de Sant Maurici is almost entirely on foot, since private vehicle traffic inside the park is restricted; hikers typically start from the Cavallers reservoir or from the Sant Nicolau valley. Given the altitude and terrain, this is a destination for people prepared for genuine high-mountain trekking rather than a short walk. What should you know before visiting? La Vall de Boí is best known for its Romanesque churches, a UNESCO World Heritage site, but the valley is also the gateway to a national park scattered with dozens of glacial lakes, Estany Perdut among them. Because of the altitude — above 2,400 metres — weather in this part of the Pyrenees can shift quickly even in summer, and snow can linger well into late spring. Anyone planning a route in this direction should check current trail conditions shortly before setting out, since markings and accessibility change with the season. Frequently Asked Questions What is Estany Perdut? It is a small glacial lake inside the Aigüestortes i Estany de Sant Maurici National Park, in the municipality of la Vall de Boí, sitting at around 2,461 metres above sea level. How big is the lake? It covers about 1.56 hectares and reaches a maximum depth of 26 metres. Is Estany Perdut connected to other lakes? Yes, its drainage links it to the nearby Estany de la Coma d'Amitges, one of many glacial lakes in this part of the park. Is it easy to get to? No — the lake lies in a high-altitude, protected section of the park reachable only on foot, after several hours of hiking from the Sant Nicolau valley or the Cavallers reservoir.

estanys de les Corticelles
la Vall de Boí
Estanys de les Corticelles is a group of small glacial lakes in the municipality of La Vall de Boí, in the Catalan Pyrenees, sitting inside the Aigüestortes i Estany de Sant Maurici National Park. Where exactly are the Corticelles lakes? The two main basins sit at roughly 2,298 and 2,278 metres above sea level, with a scatter of smaller pools dropping down to around 2,225 metres. It's the kind of high-mountain scenery typical of the central Pyrenees: rock-cut basins filled with meltwater, ringed by bare ridgelines and alpine meadows. The whole area lies within one of Spain's oldest national parks, which means strict protection and no development for kilometres around. What does the name Corticelles mean? The name comes from co(ho)rticellas, referring to small enclosures or livestock pens. It points to the pastoral past of these highlands - until fairly recently, the meadows around the lakes served as summer grazing ground for sheep and cattle, and traces of old stone walls and pens can still be spotted along the trail. How do you get there? Because the area sits inside a national park, there's no direct car access to the lakes themselves. Parking is located outside the protected core, usually near villages that belong to the municipality of La Vall de Boí, and the rest of the way has to be covered on foot. That's the standard setup across Aigüestortes park - vehicle access deep into the massif is restricted, with some stretches served only by off-road taxis or hikers. What's the hike to Corticelles like? A popular route links Estanys de les Corticelles with the nearby Estany de Dellui. It runs about 14.5 kilometres round trip with roughly 700 metres of elevation gain, which puts it in the "demanding" category - a full-day outing best suited to hikers with some mountain experience. Sturdy trekking boots, poles, plenty of water, and an extra warm layer are worth packing, since temperatures in the high Pyrenees can drop sharply even in summer. Is it worth the effort? Yes, especially for travellers after quiet trails rather than the busier routes leading to the park's best-known lake, Estany de Sant Maurici. Corticelles draws hikers who value raw high-mountain scenery over easy access - the cluster of lakes, shifting between turquoise and emerald depending on light and depth, framed by rocky peaks, ranks among the most distinctive sights in the Catalan Pyrenees. When's the best time to go? Summer, from June through September, is the best window for hiking in this part of the Pyrenees, once snow at higher elevations has cleared and the trails are passable. Outside that window, it's worth checking current conditions and possible snow on the passes, since mountain weather here can turn quickly and without much warning. Frequently Asked Questions How high up are the Corticelles lakes? The two main lakes sit at roughly 2,298 and 2,278 metres above sea level, with smaller surrounding pools dropping to around 2,225 metres. Can you drive right up to the lakes? No. Since the area is part of a national park, access is on foot only, starting from parking areas outside the park's core, typically near villages belonging to La Vall de Boí. How long is the trail to Corticelles? The popular route linking Corticelles with Estany de Dellui covers about 14.5 kilometres round trip and is considered demanding due to the roughly 700-metre elevation gain. What does the name Corticelles mean? It derives from a word for small enclosures or livestock pens, reflecting the area's pastoral past as high-altitude summer grazing land.

Estanys de Saburó d'Amunt
la Torre de Cabdella
Estanys de Saburó d'Amunt is a cluster of seven glacial lakes in the municipality of la Torre de Cabdella, sitting above 2,600 metres at the head of the Vall Fosca, in the Pallars Jussà region. Where are the Saburó d'Amunt lakes located? The lakes lie northeast of the village of Cabdella, within the municipality of la Torre de Cabdella. They occupy high mountain ground at the source of the Vall Fosca, a side valley of the Catalan Pyrenees that drains into the Flamisell river. The surrounding landscape is unmistakably alpine, ringed by bare ridgelines with only sparse high-mountain grasses growing between the rock outcrops. What does this group of lakes look like? Rather than a single lake, Saburó d'Amunt is made up of seven separate tarns sitting in a compact glacial basin. The highest of the seven is also the largest. The basin is enclosed by ridgelines running southwest from Tuc de Saburó, between the Clots de Saburó and Pales de Colomina, and to the north by the ridges of Pic de Peguera, Pic de Mar and Pic dels Vidals. This layout is a classic sign of glacial carving, where a retreating ice mass gouged out several linked hollows rather than one continuous basin. How do the lakes fit into the wider system? Saburó d'Amunt is not an isolated feature — it belongs to a larger network of twenty-six glacial lakes that feed the headwaters of the Flamisell. These lakes are linked both on the surface and underground, and Estany Gento, one of the best-known lakes in the Vall Fosca, acts as the regulator for the whole system. Water from Saburó d'Amunt flows down toward the lower-lying Petit Estany de Saburó, continuing on through the rest of this hydrological chain. The Vall Fosca has been tapped for hydropower for decades, and that history has left the valley with a distinctive landscape of interconnected reservoirs and channels running between its natural lakes. What should visitors know before heading up? This is high mountain terrain, reachable only on foot, and it calls for a reasonable level of fitness and proper preparation: sturdy trekking footwear, protection from sun and wind, and a check of the forecast, since weather at this altitude in the Pyrenees can shift quickly even in midsummer. Snow can linger here well into the season, sometimes through June or July, which is worth factoring into any plan to visit. The water itself carries the cold, clear tint typical of glacial lakes fed by melting snow rather than by streams from lower ground. Frequently Asked Questions How many lakes make up Estanys de Saburó d'Amunt? The group consists of seven lakes, with the highest of them also being the largest. At what altitude are the lakes situated? The lakes sit above 2,600 metres, at the head of the Vall Fosca valley. Are these lakes connected to other lakes in the area? Yes. Saburó d'Amunt is part of a wider network of twenty-six glacial lakes at the source of the Flamisell, linked both above and below ground, with Estany Gento acting as the system's regulator. Where does the water from these lakes go? It flows downhill toward the lower Petit Estany de Saburó, feeding into the rest of the Vall Fosca's hydrological system.

Estany Xic de Colomina
la Torre de Cabdella
Estany Xic de Colomina is a small glacial lake in the municipality of La Torre de Cabdella, in the Vall Fosca valley (Pallars Jussà, Catalonia, Spain). "Xic" means "small" in Catalan, distinguishing it from the much larger neighboring lake, Estany de Colomina. Where exactly is the lake? The lake sits at roughly 2,426 metres above sea level, in rugged mountain terrain northeast of the village of Cabdella. Its coordinates are approximately 42.520°N, 0.995°E. The area borders the Aigüestortes i Estany de Sant Maurici National Park, though the lake itself lies in the park's peripheral protection zone rather than within its strictly protected core. How big is it? Estany Xic de Colomina measures about 220 metres in length and 101 metres in width, covering roughly 1.84 hectares. That makes it considerably smaller than the adjacent Estany de Colomina, which spans over 15 hectares. Where does the water come from and go? The lake feeds into the larger Estany de Colomina, entering it from the west. Both lakes are part of an extensive network of glacial lakes in the Vall Fosca valley, linked by natural drainage and, in places, engineered channels. What peaks surround it? The surrounding ridgeline includes Pic de Saburó and Pic de la Mainera (both around 2,906 m) to the east, Pala Pedregosa de Llessui (2,881 m) to the southeast, and Pales de Colomina (2,678 m) to the northwest. The setting is classic high-Pyrenean terrain: bare rock, sparse alpine vegetation, and a scattering of smaller tarns nearby. Does the lake tie into hydroelectric power? Yes. The Cabdella lakes (Catalan: estanys de Cabdella), which include Estany Xic de Colomina, were incorporated into a hydroelectric system built between 1911 and 1914 by the company Energía Eléctrica de Cataluña. The neighboring Estany Gento acts as the system's flow regulator, and water from the higher lakes, including Colomina, ultimately supplies the power station in the Vall Fosca valley. How do you reach the lake? The area is a popular hiking destination. One recommended route links Coll del Triadó, Estany Gento, Estany de Colomina and Estany de Mar — about 21 km long, roughly 6.5 hours, with around 516 m of elevation gain. Estany Xic de Colomina sits along this broader lakes circuit, so it's usually visited as part of a longer day in Vall Fosca rather than as a standalone destination. Frequently Asked Questions What's the difference between Estany Xic de Colomina and Estany de Colomina? Estany Xic ("small") is much smaller — about 1.84 hectares versus more than 15 hectares for the neighboring lake it flows into. How high up is the lake? Around 2,426 metres above sea level, in the high-mountain section of the Vall Fosca valley. Is the lake inside a national park? It sits right next to the Aigüestortes i Estany de Sant Maurici National Park, in the park's peripheral zone rather than inside the strictly protected core area. What's the best way to plan a visit? Most visitors see it as part of a longer hiking route connecting several Cabdella lakes, such as via Estany Gento and Estany de Mar — plan for a full day.

Estanys de Carboneres
la Torre de Cabdella
Estanys de Carboneres is a small group of glacial lakes in the municipality of la Torre de Cabdella, in Lleida province, in the Catalan Pyrenees. Where are the Estanys de Carboneres located? The lakes sit in the Vall Fosca (also known as Vall del Flamisell), within the municipality of la Torre de Cabdella. This high-mountain corner of the Pyrenees is known for its dense network of glacial lakes, carved out by the glaciers that once shaped the local cirques and valleys. Estanys de Carboneres lies close to other similar lakes, including the Estanys de la Muntanyeta, making this stretch of the valley one of its richest in terms of alpine lake scenery. How big are the lakes, and how high up are they? Estanys de Carboneres is a cluster of three small lakes, sitting at an altitude of roughly 2,400–2,550 metres above sea level. The largest of the three covers around 0.4 hectares — a typical size for the high-altitude tarns scattered across the Pyrenees, most of which rarely exceed a few hectares. Because of the elevation, the lakes stay snow- or ice-covered for much of the year, and easy access to the water's edge and surrounding slopes is really only possible during the summer months. What else is worth knowing about the area? La Torre de Cabdella is a small municipality covering more than 165 square kilometres and home to a few hundred residents, spread across the Vall Fosca. The region has long attracted mountain hikers, trail runners and ski tourers, thanks to its abundance of lakes and high mountain passes. The valley has tourism infrastructure built around its many estanys, with trails connecting one lake to another throughout Vall Fosca. Estanys de Carboneres, while less well known than the valley's largest lakes, makes a natural target for visitors looking for quieter, more remote high-mountain routes. Who are these lakes suited for? This is primarily a destination for experienced mountain hikers — the altitude above 2,400 metres and the typically rocky Pyrenean terrain call for good fitness, proper footwear and caution, especially outside the summer season when snow and ice can make the approach harder. For anyone planning a longer stay in Vall Fosca, Estanys de Carboneres can be one stop on a route linking several of the region's high-altitude lakes. Frequently Asked Questions Where exactly are the Estanys de Carboneres? In the municipality of la Torre de Cabdella, in the Vall Fosca valley, Lleida province, Catalan Pyrenees. How many lakes are there and how big are they? There are three small glacial lakes, the largest of which covers about 0.4 hectares. How high up are they? At an altitude of roughly 2,400–2,550 metres above sea level, typical for high-mountain Pyrenean tarns. Is this a popular tourist destination? They're less known than Vall Fosca's largest lakes, but they make a natural stop for hikers seeking quieter, high-altitude routes through the valley.

Estany de Carbonera
la Torre de Cabdella
Estany de Carbonera is a small glacial lake in the municipality of La Torre de Cabdella, in the Catalan Pyrenees, province of Lleida. Where is Estany de Carbonera located? The lake sits in the Vall Fosca valley, at the northern edge of the Pallars Jussà region. This is classic high-Pyrenean terrain — rocky ridges, steep glacial valleys and dozens of small lakes scattered across them, carved out by glaciers during the last ice age. Estany de Carbonera is one of many such bodies of water in the area, though less prominent than the largest lakes nearby. What are the Cabdella lakes? The area around La Torre de Cabdella is known for a network of mountain lakes collectively called the estanys de Cabdella. Dozens of reservoirs at different altitudes were linked in the first half of the 20th century by underground tunnels, an engineering project built for hydroelectric purposes — it allowed meltwater and rainfall to be gathered and channelled toward the power plants of the valley below. That system still feeds the dams and power stations of Vall Fosca today, and the lakes themselves have become a draw for hikers. Estany de Carbonera belongs to this broader mosaic of water bodies that shaped the region's outdoor-tourism identity. Is the lake connected to hydroelectric infrastructure? Very likely in a general sense, though no confirmed detail describes the specific role of Estany de Carbonera within the network. What is documented is the scale of the surrounding system: the reservoir at the Sallente dam and Estany Gento, reachable since 1990 by a cable car linking 1,770 m and 2,573 m above sea level, together form part of the infrastructure used by the Vall Fosca hydroelectric plants. That gives a sense of the wider system the lake sits within. How do you get there? La Torre de Cabdella is the municipality covering the whole of Vall Fosca, formed in 1970 through the merger of the former villages of Mont-ros and la Pobleta de Bellveí with the historic Torre de Cabdella. Access is via local roads running up the valley from the Pallars Jussà side. Given the mountainous terrain and the altitude at which the lakes sit, reaching many of them on foot requires several hours of hiking — the exact route and duration depend on the chosen starting point, so it is worth checking an up-to-date trail map before setting out. What can you do in the area? Vall Fosca is well known among high-mountain trekkers — its many lakes, including those near Estany de Carbonera, serve as natural resting points and waypoints along the trails. In summer, multi-day traverses through the Pyrenees are popular, and the cable car at the Sallente dam makes it easier to reach the upper part of the valley without a long approach on foot. The area also draws landscape photographers, thanks to the contrast between granite peaks and blue mountain water that is typical of this stretch of the Pyrenees. Frequently Asked Questions What is Estany de Carbonera? It is a glacial lake in the municipality of La Torre de Cabdella, in the Lleida Pyrenees, one of many mountain lakes found across the region. Is the lake part of a hydroelectric system? The Cabdella lakes area is known for underground tunnels linking numerous reservoirs to serve the Vall Fosca hydroelectric plants, although the specific role of Estany de Carbonera within that network is not clearly documented. How do you reach Estany de Carbonera? The starting point is the municipality of La Torre de Cabdella, accessible via local roads from Pallars Jussà; reaching the lake itself usually requires hiking along mountain trails. What else is worth seeing nearby? Other lakes in the Vall Fosca valley, the Sallente dam, and the cable car up to Estany Gento, which gives easier access to the higher parts of the range.

Estanys dels Vidals d'Amunt
la Torre de Cabdella
Estanys dels Vidals d'Amunt are a group of three high-mountain glacial lakes in the municipality of la Torre de Cabdella, in the Catalan Pyrenees. Where are Estanys dels Vidals d'Amunt located? The lakes sit at roughly 2,670 metres above sea level, at the headwaters of the Vall Fosca valley, in the Pallars Jussà region, northeast of the village of Cabdella. Their basin is framed on one side by the southern slopes of Pic dels Vidals and on the other by the Serreta dels Vidals ridge. That combination of altitude and bare rock gives the surrounding landscape a stark, alpine character that contrasts with the greener lower reaches of Vall Fosca. How did these lakes form? They are classic cirque lakes, carved out by glacial action in the bedrock of the highest parts of the Pyrenees. The three basins that make up Estanys dels Vidals d'Amunt are similar in size and appearance, and mainly differ in how they drain: the eastern lake feeds directly into Estany Vidal, while the western one sends its outflow through a stream that also reaches Estany Vidal on its way toward Estany Tort. That makes the Vidals d'Amunt lakes one link in a longer chain of high-altitude lakes in this stretch of the Pyrenees. Who are these lakes for, and is the visit worth it? This is terrain for hikers already comfortable with high-mountain walking — the ground around the lakes is open, rocky, and has no tourist infrastructure. Most visitors reach them as part of a longer route linking several estanys across Vall Fosca, rather than as a standalone short outing. The reward is the sight of three clear pools set into a rocky bowl, framed by views of the neighbouring peaks. When is the best time to visit? Given the altitude — close to 2,700 metres — snow can linger here for much of the year, and unassisted access is realistically limited to summer and early autumn. Outside that window, reaching the lakes calls for winter mountaineering experience and appropriate gear. What about the surrounding lakes? Estanys dels Vidals d'Amunt are not an isolated stop: they border Estany Vidal and sit along the water route that continues toward Estany Tort, one of the better-known lakes in this part of the Pyrenees. For anyone planning a longer stay in Vall Fosca, they form a natural link in a route that strings together several high-mountain lakes in a single trip. Frequently Asked Questions Where exactly are Estanys dels Vidals d'Amunt? In the municipality of la Torre de Cabdella, in the Pallars Jussà region, at the headwaters of Vall Fosca, at around 2,670 metres of altitude, northeast of Cabdella. How many lakes make up this group, and how do they differ? Three, all similar in size. The main difference is drainage: the eastern lake flows directly into Estany Vidal, while the western one reaches Estany Vidal via a stream that continues toward Estany Tort. Is the hike to the lakes difficult? Yes — this is high-mountain terrain, rocky and without infrastructure right at the lakes, so it requires proper preparation and experience walking in the high Pyrenees. When is the best season to go? Summer and early autumn, when the high routes are most accessible; outside that period the area can stay snow-covered for a long time.

Laguna de Las Verdes
Cabrillanes
Laguna de Las Verdes is a glacial lake in the municipality of Cabrillanes, in the Babia region of León province, Castile and León. Where is Laguna de Las Verdes located? The lake sits roughly 5 km north of the village of Torre de Babia, inside a glacial cirque enclosed by limestone peaks. Its water comes from snowmelt running off the cirque walls and from the Torre stream, which feeds the lake for most of the year. How do you get there? The hike starts in Torre de Babia. The route follows the Torre stream valley up toward Majada de Merinas, a highland pasture where the wide track narrows into a footpath. From there the path climbs directly to the lake basin. It's a typical high-mountain approach — no paved surfaces, but a clearly worn shepherd's trail. What makes this lake distinctive? Unlike most glacial lakes, which tend to be deep, Laguna de Las Verdes is shallow. The reason is sediment buildup on the lakebed — rock and debris washed down from the surrounding slopes, especially from the foot of Montihuero. In summer, aquatic vegetation spreads across the bottom and edges, tinting the water green — which is exactly where the lake gets its name ("Verdes" means "greens"). Which peaks surround the lake? The basin is enclosed by limestone summits typical of the Babia range: Montihuero (2,187 m), Aguja de las Coloradas (2,006 m), Peña Los Años (2,157 m), and Peña Chana (2,068 m). Their steep, rocky flanks form the natural amphitheater holding the lake, and most of its meltwater runoff comes from these same slopes during the thaw. Who is this hike suited for? Given its altitude — the lake sits above 1,700 m — and the rugged terrain, the route suits hikers already comfortable with mountain ascents. The payoff is a view of one of the few glacial lakes in the Babia region, set in an unspoiled, lightly visited high-mountain landscape. Frequently Asked Questions Is Laguna de Las Verdes deep? No. Despite its glacial origin, it's a shallow lake because its bed has filled with sediment and rock carried down from the slopes, mainly from the base of Montihuero. Where does the lake's name come from? The name refers to the green color the water takes on in summer, caused by aquatic vegetation growing across the lakebed. Where does the trail to the lake begin? The trailhead is in Torre de Babia. The route follows the Torre stream valley, passes Majada de Merinas, and then climbs a shepherd's path to the lake itself. What peaks can be seen from the lake? Montihuero, Aguja de las Coloradas, Peña Los Años, and Peña Chana — the limestone summits ringing the glacial cirque — are all visible from around the lagoon.

Laguna del Donadío
Santaella
Laguna del Donadío is a seasonal lagoon in the municipality of Santaella, in the province of Córdoba, Andalusia. Where is Laguna del Donadío located? The lagoon sits in the south of Córdoba province, close to the border with Seville province and not far from the Genil River, at an elevation of roughly 243 metres. It lies about 40 km south of the city of Córdoba. Its name comes from the neighbouring Cortijo del Donadío, a traditional Andalusian rural estate that has carried this name for generations. Why is it called "Donadío"? The word "donadío" derives from the Latin "donativum," referring to land grants a king awarded to those who served him. After Córdoba was retaken during the Reconquista, King Ferdinand III ("the Saint") distributed the surrounding lands among bishops, military and religious orders, nobles, and courtiers who had taken part in the campaign. That history survives today in the name of both the estate and the lagoon beside it. What wildlife can be found here? Laguna del Donadío is a shallow wetland whose surface area expands and shrinks with rainfall, a pattern typical of Mediterranean endorheic lagoons. Although the surrounding land is privately owned, the lagoon has long been regarded as one of the more important birdwatching sites in Córdoba province, and the municipality of Santaella has designated it a Lugar de Interés Ornitológico (a site of ornithological interest). Species recorded here include flamingos, red-crested pochards, purple swamphens, coots, northern shovelers, mallards, and the white-headed duck — a species considered endangered across Europe, for which Andalusia is one of the few remaining breeding areas. Black-winged stilts and marsh harriers hunting over the reed beds are also commonly seen. How do you get to the lagoon? A walking trail of about 3 km one way leads to Laguna del Donadío, rated easy and suitable for most visitors interested in nature and birdwatching. The route, called "Ruta de Paisajes con Historia," is promoted by the Diputación de Córdoba and the Ayuntamiento de Santaella; a night-time version of the same trail also exists, popular with stargazers and those drawn to the quiet of the wetland after dark. Frequently Asked Questions Can visitors access Laguna del Donadío? The land around the lagoon is privately owned, but a marked walking trail brings visitors close enough to observe the water and its birdlife without entering private property. What birds is the lagoon known for? It is noted for flamingos, the endangered white-headed duck, purple swamphens, northern shovelers, black-winged stilts, and marsh harriers — the reason it was designated a site of ornithological interest. How far is the lagoon from Córdoba city? It lies about 40 km south of Córdoba, within the municipality of Santaella. Is the night trail worth doing? Yes — a nocturnal version of the "Ruta de Paisajes con Historia" trail exists, valued for its quiet and stargazing potential, though it requires proper lighting and preparation.

Estany de Filià
la Torre de Cabdella
Estany de Filià is a small glacial lake in the municipality of la Torre de Cabdella, sitting at 2,134 metres above sea level at the head of the Vall Fosca valley in the Pallars Jussà region of Catalonia. Where is Estany de Filià located? The lake lies southwest of the village of Cabdella, on the north-eastern slopes of the Tossal de la Costa peak. It holds the distinction of being the southernmost lake in the entire Pyrenees range, positioned at the headwaters of the Noguera Pallaresa river. Its remote high-mountain setting means reaching it involves a hike up from the lower valley. How big is the lake? Estany de Filià is modest in size: it covers roughly 1.8 hectares and reaches a maximum depth of 5.5 metres. Given these dimensions, it is noticeably smaller than several other lakes in the surrounding area, making it a quiet, intimate stop along a mountain route rather than a headline destination in itself. What is Vall Fosca, and why does the region have so many lakes? The municipality of la Torre de Cabdella is known to visitors as Vall Fosca and comprises 19 villages spread across altitudes from 800 metres (Pobleta de Bellveí) up to 1,420 metres (Cabdella). The valley's headwater area is a landscape of glacial cirques — Filià, Riqüerna, Rus and Estany Gento — that together hold more than 30 lakes. Estany de Filià is one of them, a good example of the alpine terrain shaped by past glacial erosion that defines this part of the Pyrenees. What should visitors know before heading to Estany de Filià? Because the lake sits well above 2,100 metres in an exposed high-mountain zone, weather can turn quickly and snow can linger on the approach trails late into the season. Given the altitude and isolation, it is worth allowing enough time for the hike in and checking current trail conditions before setting out. This is a destination suited to hikers prepared for high-mountain terrain who want to experience a wilder, less-visited corner of the Pyrenees. Frequently Asked Questions How high up is Estany de Filià? The lake sits at 2,134 metres above sea level. How large is the lake? It covers about 1.8 hectares with a maximum depth of 5.5 metres — a small body of water compared to other lakes in the region. Where exactly is Estany de Filià relative to Cabdella? It lies southwest of the village of Cabdella, on the slopes of Tossal de la Costa, at the head of the Vall Fosca valley. Are there other lakes nearby? Yes. The head of Vall Fosca contains four glacial cirques (Filià, Riqüerna, Rus and Estany Gento) holding more than 30 lakes in total, making it one of the richest concentrations of high-mountain lakes in the Pyrenees.

bassa de Sarradé
la Vall de Boí
Bassa de Sarradé is a small glacial lake in the municipality of La Vall de Boí, tucked high in the Catalan Pyrenees. Where is Bassa de Sarradé located? The lake sits within the Aigüestortes i Estany de Sant Maurici National Park, in the Sarradé valley - a side valley of the larger Ribera de Sant Nicolau, in the Alta Ribagorça region of Catalonia. Its coordinates are 42.570401, 0.90097, and the lake itself lies above 2,400 metres, in a high, rocky part of the park. How did this lake form? Bassa de Sarradé is a classic glacial lake, filling a basin carved out by the glacier that once covered the Sarradé valley during the last ice age. Small mountain lakes and ponds of this kind, known locally as "basses" and "estanys," are typical of the high-altitude Catalan Pyrenees and appear in large numbers throughout the national park, which is renowned precisely for its scattering of glacial lakes among granite peaks. What surrounds the lake? Water from Bassa de Sarradé flows south-southeast through a stream hidden among boulders, known as the Canalot de Sarradé d'Amont. Further downstream it joins the waters of the Canal del Racó and feeds the lower-lying Estany de Sarradé, at around 2,123 metres - another lake in the same drainage system, which also collects runoff from the slopes of Pic de la Pala Alta de Sarradé and the Canals de l'Estràs. That same peak rises above the valley and is a popular destination for more experienced mountain hikers exploring the park. How do you get there? The Sarradé valley is reached on foot from the Ribera de Sant Nicolau valley, the main access route into the eastern side of the national park from La Vall de Boí. Given the altitude, the rocky terrain, and the absence of easy marked paths right around the lake, it is mainly visited by hikers prepared for high-mountain trekking - ideally in summer or early autumn, once the trails are clear of snow. What else should visitors know about La Vall de Boí? The municipality of La Vall de Boí, which administers the area around the lake, is best known for its group of Romanesque churches inscribed on the UNESCO World Heritage List, and for bordering the Aigüestortes i Estany de Sant Maurici National Park - the only national park in Catalonia. It is from here that many visitors set out on multi-day routes into the mountains, including into side valleys such as Vall de Sarradé. Frequently Asked Questions What is Bassa de Sarradé? It is a small glacial lake in the Sarradé valley, within the Aigüestortes i Estany de Sant Maurici National Park, administratively part of the La Vall de Boí municipality. How high up is the lake? The lake lies above 2,400 metres, in a high, rocky section of the Catalan Pyrenees. Are there other lakes nearby? Yes. Water from Bassa de Sarradé flows down to the lower Estany de Sarradé (around 2,123 metres), which is also fed by other streams in the same valley. Is the lake hard to reach? The Sarradé valley is high-mountain, rocky terrain with no easy marked paths right around the lake, so reaching it requires good physical preparation and proper hiking gear; summer or early autumn is the best time to visit.

estany de Xemeneia
Alt Àneu
Estany de Xemeneia is a small glacial lake in the municipality of Alt Àneu, in the Pallars Sobirà county (Lleida province, Catalonia). It sits in a high-mountain section of the Pyrenees, at an altitude typical of the many "estanys" (mountain lakes) scattered across this region. Where is estany de Xemeneia located? The lake lies at coordinates 42.614°N, 1.017°E, near the locality of Pales de Nollerme and the Vall de Cabanes valley. This part of the Alt Àneu municipality is among the most mountainous and sparsely populated areas of Pallars Sobirà — a county known for its dense network of glacial lakes tucked into high-altitude cirques shaped by past glacial erosion. What kind of lake is it? Estany de Xemeneia is described as a small body of water — one of several minor lakes forming the hydrological system of the Cabanes valley. Its outflow drains toward estany Negre de Cabanes, a considerably larger glacial lake in the same valley. This pattern, where smaller lakes feed larger ones lower down the slope, is typical of Pyrenean glacial cirques, where snowmelt and rainfall cascade between successive rock basins. Is it a well-known hiking destination? Unlike the Pyrenees' better-known lakes, estany de Xemeneia is not widely covered in tourist guides — available information is limited to its geographic position and its connection to the nearby estany Negre de Cabanes. Anyone planning a trip to this area should focus on the broader character of the Vall de Cabanes valley: rugged, high-mountain scenery typical of the less-frequented corners of Pallars Sobirà, in contrast to the more popular and better-marked trails of the neighboring Aigüestortes area. What should visitors know before heading there? Given the high-mountain setting and the limited amount of publicly available detail on this specific lake, it is best approached as one point of interest within a wider exploration of the Cabanes valley rather than as a standalone, well-documented destination. Anyone interested in visiting should carry up-to-date topographic maps of the Pallars Sobirà region and plan the route with high-mountain conditions in mind, since weather in the Pyrenees can shift quickly regardless of season. Frequently Asked Questions Where exactly is estany de Xemeneia located? In the municipality of Alt Àneu, Pallars Sobirà county (Lleida province), near Pales de Nollerme and the Vall de Cabanes valley. Is estany de Xemeneia a large lake? No — sources describe it as a small lake, one of several minor bodies of water in the Cabanes valley. Which other lake is it connected to? Its waters drain toward estany Negre de Cabanes, a larger glacial lake in the same valley. Is it a popular tourist spot? It is not a widely known destination — available information about the lake itself is limited compared to the region's more recognizable lakes in Pallars Sobirà.

estany de Sarradé d'Amunt
la Vall de Boí
Estany de Sarradé d'Amunt is a small glacial lake in the municipality of la Vall de Boí, tucked into the high-mountain Vall de Sarradé within the Aigüestortes i Estany de Sant Maurici National Park in the Catalan Pyrenees. Where exactly is this lake? The lake sits in the upper reaches of the Sarradé valley, at roughly 2,500 meters above sea level, close to the administrative edge of la Vall de Boí. It's a classic cirque lake, carved by glacial action into a hollow ringed by rocky ridges. Its coordinates, 42.574368, 0.903252, place it deep inside a mountain massif whose peaks — Pala Alta del Sarradé and Pic de Sarradé among them — rise above 2,900 meters. How do you get there? Most visitors start from the Pista d'Aigüestortes, the broad track running into the park from the area around Estany de Llebreta, at about 1,620 meters. From there the route climbs the Sarradé valley, passing smaller pools along the way, up to the main Estany de Sarradé at 2,123 meters, then continues on a steeper stretch to reach the upper lake, Sarradé d'Amunt. The approach demands decent fitness and sturdy footwear — the ground is rocky, and the final section gains considerable elevation. What does the lake itself look like? It's a modest body of water, with a surface area estimated at roughly one hectare, draining toward the south. The outflow feeds first into the Bassa de Sarradé, a smaller pool just below, and then into the main Estany de Sarradé. Water from the whole Sarradé lake system eventually reaches the Barranc de Sarradé and from there the Riu de Sant Nicolau, one of the park's principal rivers. The surroundings are stark high-mountain terrain — bare rock and alpine turf, with barely any trees, since the site sits above the treeline. Why make the trip up here? The Sarradé valley sees far fewer visitors than the well-trodden routes around Estany de Sant Maurici or Estany Llong, which makes it a good pick for anyone looking for quiet and a closer brush with the park's wilder side. The views along the way — from Llebreta, past the main Sarradé lake, up to the higher Sarradé d'Amunt — rank among the most striking in this part of Aigüestortes. This is a destination for experienced hikers, not a short family outing. Frequently Asked Questions Can you drive to the lake? No. Estany de Sarradé d'Amunt lies in the core zone of the national park, reachable only on foot. The nearest point with vehicle access is around Estany de Llebreta. How long is the hike? The round trip runs to several kilometers with substantial elevation gain, so plan for a full day and solid preparation. Is the lake on a marked trail? Yes, the Sarradé valley forms part of the Aigüestortes National Park trail network, though markings in the upper stretches are sparser than on the main routes. Is there anything else worth seeing nearby? Yes — the route passes several other lakes, including the main Estany de Sarradé, and the surrounding peaks, many over 2,900 meters, draw hikers interested in high-mountain trekking.

estany d’Aigüissi
la Vall de Boí
Estany d'Aigüissi is a small glacial lake in the municipality of La Vall de Boí, in the Spanish Pyrenees. Where is estany d'Aigüissi located? The lake sits in the Vall de Sarradé, within the Aigüestortes i Estany de Sant Maurici National Park, in the Alta Ribagorça region of Catalonia. It lies at roughly 42.565 N, 0.883 E, above 2,100 metres of elevation — well into the high-mountain zone, above the treeline. How big is the lake? Estany d'Aigüissi is a compact body of water: its surface covers about 4.2 hectares, and its maximum depth reaches around 24 metres. That scale is typical of the many glacial tarns scattered across this stretch of the Pyrenees, carved out of rock basins left behind as the region's glaciers retreated thousands of years ago. The lake is fed mainly by snowmelt and local rainfall, so its water level and appearance shift noticeably with the seasons. What is the Aigüestortes National Park? Estany d'Aigüissi lies within the Aigüestortes i Estany de Sant Maurici National Park — Catalonia's only national park and one of the few in Spain that protects a genuinely high-mountain Pyrenean landscape. It is defined by granite terrain, steep ridgelines approaching 3,000 metres, and a striking density of glacial lakes and tarns scattered through its valleys and cirques. The park's name itself — roughly "twisted waters" in Catalan — refers to the meandering streams that wind between these rocky basins. How do you get to estany d'Aigüissi? The lake is reached on foot, via trails starting from the Vall de Boí, the main gateway for hikes into this part of the park. Motor traffic deep inside the park is restricted to protect the environment, so movement is mostly by hiking or via the local shuttle services that operate at the park's access points. Because the terrain sits well above 2,000 metres and Pyrenean weather can change quickly, it's worth planning any visit with margin for both altitude and conditions. Frequently Asked Questions Is estany d'Aigüissi a natural lake? Yes — it is a glacial lake, formed by the action of ice, not an artificial reservoir. How high up is the lake? It sits above 2,100 metres of elevation, in the high-mountain section of the Pyrenees. Are there other lakes nearby? Yes. The Vall de Boí and the wider Aigüestortes National Park are known for their large number of glacial lakes and tarns spread across the surrounding cirques. Can you drive to the lake? No. Motor vehicle access deep inside the park is restricted; the lake is reached on foot or via local shuttle services operating at the park's entry points.
