Lac de Montriond

Lac de Montriond is an Alpine lake nestled beneath steep mountain cliffs in Haute-Savoie, with a walking path circling its perimeter. The water reaches depths of about 19 meters and provides space for swimming, paddling, and fishing.

The lake formed several thousand years ago when a landslide from the Nantaux mountain created a natural dam across the river valley. This geological event created the body of water that exists here today.

This body of water sits at the heart of the Chablais UNESCO Global Geopark, where visitors can observe how geological forces shaped the Alpine landscape. The cliffs surrounding it tell the story of these natural processes through their exposed rock layers.

The lake is easily accessible and offers various recreational activities during summer months, including boat rentals and designated swimming areas. The flat walking path around it suits visitors of all abilities and provides the best way to explore the surroundings at a relaxed pace.

During winter, the water surface freezes solid, creating an unusual diving location where both beginner and experienced divers can explore beneath the ice. This rare activity attracts adventurers seeking the distinctive sensation of ice diving.
