Lac des Bouillouses

Lac des Bouillouses is an artificial lake in the Pyrenees at 2,016 meters elevation, spreading across about 149 hectares of mountain terrain. Its clear waters are encircled by steep rock faces and serve as a crucial water storage facility for the region.

The lake was created between 1903 and 1910 through a masonry dam construction that demanded considerable effort and resources. This early engineering achievement enabled hydroelectric power generation in the mountains and supported regional economic growth.

The lake powers the Yellow Train, a regional railway connecting mountain communities and representing local transportation heritage. This connection shows how water resources shape the region's traditional infrastructure.

Marked hiking trails circle the lake, including the long-distance GR10 path, offering several access points for visitors. Summer months from June to September are ideal for exploring, as the trails are generally snow-free and weather is more stable.

The water is also used for snow production at nearby ski resorts, showing how an older infrastructure serves multiple modern purposes. This dual use allows the mountain to remain active throughout the season.
