Estany d'Eixerola

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.
