Lac de Montriond: Swimming, Walks, Activities, and Practical Guide

Nestled in the Aulps valley, at the foot of high cliffs and a conifer forest, the Montriond lake is the third largest lake in Haute-Savoie after Lake Geneva and Lake Annecy. Just a few minutes from Morzine and Avoriaz, it is easily discovered with family: walking around the lake, supervised swimming, paddleboarding or fishing in summer, and a great northern atmosphere once winter arrives.

Here is the complete guide to prepare your visit to Montriond lake.

Montriond lake: a Canadian setting in the heart of the Alps

Nestled at 1,072 meters altitude, Montriond lake occupies a steep valley dominated by the majestic Nantaux mountain. When the water is perfectly calm, it reflects the fir trees and rocky cliffs, offering a wild landscape that has earned it the nickname “Canadian Lake” or “Green Lake”.

đź’ˇ Did you know?

With its 33 hectares, it is the third largest natural water body in Haute-Savoie after Lake Geneva and Lake Annecy.

Unlike many high-altitude lakes accessible only after long hours of walking, Montriond stands out for its very easy access by car or shuttle, making it a flagship destination for families and holidaymakers staying in the Aulps valley.

Origin and history of Montriond lake

A lake born from a landslide

For hundreds of thousands of years, glaciers carved the Montriond valley. After their retreat, the slopes became weakened. A section of the Nantaux mountain then collapsed into the bottom of the valley, forming a natural dam on the Dranse de Montriond. Water accumulated behind this pile of rocks to give rise to the lake.

The exact date of this collapse remains uncertain: depending on sources, estimates range from several millennia to only a few centuries ago.

From Baron de l’EspĂ©e to the 1990 works

The rubble dam was not watertight, so the lake level varied greatly between spring and autumn. Around the 20th century, the Baron de l’EspĂ©e, a wealthy patron, became passionate about the site. He invested in its development, tried to stabilize the water level, and had a residence built that was modern for its time. His efforts were unsuccessful but are part of local history.

It was not until 1990, with significant waterproofing work carried out by the municipality, that the water level stabilized. From then on, the lake became the leisure base we know today.

Walking around Montriond lake

This is the unmissable activity on site. The loop trail, easy and mostly flat, suits both children and casual walkers.

Montriond lake in winter

When the cold sets in, the lake completely changes its face. Nestled at the foot of the cliffs, it receives very little sun in the heart of winter. Its surface often freezes, and the snow transforms the site into a great northern landscape. It is one of the most beautiful seasons to discover it, and much less crowded than summer.

Cross-country skiing and snowshoeing

The calm of the snowy lake attracts cross-country skiing enthusiasts and snowshoe walkers. It is an ideal outing for a quiet half-day, as an alternative to the slopes of Morzine and Avoriaz.

Ice diving

For a truly original experience, Montriond lake is one of the few ice diving spots in the region. Divers, supervised by professionals, descend through a hole cut into the thick ice layer.

Winter precautions

  • Never walk on the frozen lake: the ice thickness is uneven and the risk is real.
  • The valley bottom is very cold and little sunny: bring warm clothes, even in good weather.
  • Prefer the free winter shuttle: the road can be snowy.

The lake in autumn
