Green Lake Loop

From Plaine-Joux, go down the road and forest trails, following the markings to reach Lac Vert from below.

In summer, a development allows you to go around the lake in about fifteen minutes. The extraordinary transparency of the water 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 coloring seduces Mont-Blanc, which often gives off its majestic reflection on the calm surface of the lake.

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