Autumn, Summer, Spring


From Plaine-Joux, descend by the road and the paths in the forest, following the markings to reach Lac Vert from below.

In summer, an arrangement allows you to go around the lake in about fifteen minutes. The extraordinary transparency of the waters makes it possible to observe an accumulation of trees and plants at the bottom of the lake. These elements, combined with the presence of blue algae, give the lake its remarkable emerald green color. This magical color seduces Mont-Blanc, which often casts its majestic reflection on the calm surface of the lake.

For the return, from the parking lot of the Lac Vert restaurant, take the track leading to the Châtelet d'Ayères refuge then turn left to pass above the lake and reach Plaine-Joux.

Swimming is prohibited at Lac Vert. Mountain lakes are fragile ecosystems. The addition of organic or chemical matter (sunscreen, buoys, etc.) profoundly transforms their functioning. Want to know more ? http://www.lacs-sentinelles.org/
