Lac d'Issarlès, Natural lake in Le Lac-d'Issarlès, France
Located at 1,000 meters elevation, Lac d'Issarlès extends over 90 hectares with depths reaching 108 meters in the Ardèche department.
The formation of Lac d'Issarlès occurred through volcanic activity, creating a maar crater that filled with water over geological time periods.
Local residents maintain fishing traditions at the lake, targeting species such as rainbow trout, Arctic char, and whitefish throughout the seasons.
A 5-kilometer marked trail circles the entire lake, offering access to multiple observation points and recreational areas for visitors.
The lake resides within a volcanic crater, containing underground caves carved into explosion products from the maar formation.

The lakes of Auvergne-Rhône-Alpes showcase remarkable geological diversity. The natural glacial lakes such as Bourget and Annecy contrast with the deep volcanic lakes of Pavin and Bouchet. The artificial lakes of Serre-Ponçon and Monteynard complete this hydrographic network. This region includes high-altitude lakes in the Alps and the Massif Central, plains water bodies, and hydropower dam reservoirs.
