The path around the lake takes you through landscapes that have succeeded for 20 000 years.
You'll walk along this mountain lake and then climb along a waterfall beneath the woods. You reach the peaceful Cubourré plateau, bathed by a stream and overlooked by the Pointe d'Entre Deux Pertuis and the Pointe de Chavache. A wide track leads to a mysterious boulder. On the way back, you can stay on the track: it leads straight back to the parking lot.
