In a forest setting, near the site of Passy Plaine-Joux, a lake bordered by spruces where Mont Blanc is reflected.
In a forest setting, near the site of Passy Plaine-Joux, the Lac Vert certainly does not usurp its name...
An exceptional natural space accessible to all, fitted out for walking.
The extraordinary transparency of the waters allows you to observe an accumulation of trees and plants at the bottom of the lake.
These elements, combined with the presence of blue-green algae, give the lake its remarkable emerald green color.
Altitude: 1200m. Magnificent view of the Mont Blanc massif.
