The lake is one of 20 geosites in the UNESCO Chablais World Geopark. Educational panels explain the geological evolution of the Lac des Plagnes and Cubourré site. Of glacial origin, it offers a glimpse of landscapes that have evolved over the past 20,000 years.

The lake is accessible by car and has a parking lot, while visitors can stroll along the lakeside dyke.
After the snow melts, you can walk around the lake on the "chemin du lac", which is not accessible to baby carriages or people with reduced mobility. In season, restaurants and picnic tables near the lake allow you to enjoy the area.

To quench your thirst or spend the night in the mountains, the Tindérêts refuge is about an hour and 15 minutes away.

Campervans are not allowed on the parking lot at night.
