Lac Achard, Glacial lake in Chamrousse, France.
Located at an elevation of 1917 meters, Lac Achard extends 260 meters in length and 100 meters in width within the Belledonne mountain range.
This natural water body formed during the last glacial period when ice movements carved out the basin in the mountain landscape.
The lake belongs to the protected Espace Naturel Sensible area, where regulations maintain the preservation of local mountain ecosystems and wildlife.
Visitors can reach the lake through marked trails from Chamrousse 1750, with the closest parking area located just 100 meters from the water.
The main lake connects to several smaller bodies of water that gradually fill up, creating a network of alpine pools in the mountain environment.

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.
