Étang du Lanoux

Étang du Lanoux is a glacial lake situated high in the Pyrenees, formed by ancient glaciers that carved out this mountain basin. Today, a dam regulates the water level and supplies this reservoir to serve regional needs.

The lake entered international attention after a dam was built in the mid-20th century, transforming its size and purpose. This construction sparked a legal dispute between France and Spain over water rights and shared mountain resources.

The lake serves as a research site for scientific teams studying high-altitude aquatic ecosystems and their adaptation to extreme mountain conditions.

Reach this mountain lake by hiking through alpine trails that wind through the surrounding Carlit area. Weather conditions change quickly at high altitude, so bring protective gear and start early to make the most of daylight.

The water is managed for both storage and hydroelectric production, making it a working resource rather than simply a natural wonder. Few visitors realize that the power generated here flows down to valleys below.
