Sustainable mountain destination

Lac des Chéserys

Let's protect our natural resources together

An exceptional and fragile territory

The Chamonix Valley is situated in an exceptional natural setting. Eternal snow, glaciers, mountain pastures, forests, high altitude lakes and wetlands, wherever you are, these landscapes are within your sight. The richness of the natural environment is characterised by a remarkable diversity of flora and fauna.

Very early on, local authorities became aware of the special nature of their environment and its fragility by carrying out numerous actions. Today, this competence has been taken over by the Community of Communes of the Chamonix Mont-Blanc Valley, which wishes to reconcile the protection of the environment, human activities and public awareness by carrying out actions for the protection, management and enhancement of natural areas with its partners.
