Vallon Lake

Cut out for experienced walkers, the ascent towards Vallon Lake touches the limit of the heart of the Park. Here, the geological diversity and the view of the massifs give an informative insight in to the formation of the Alps.

It is best to leave your vehicle beside the Chantelouve church in the hamlet of Bosses. Cross the Malsanne on a wooden walkway, then, on a track traced across a vast shale slope, reach the place which is a timber depot... From there, continue on the forest trail, cross the gorge of the Malsanne on Moulin bridge and follow diagonally right on the path going through a little wood coming out into a vast valley scattered with boulders. At the bottom of the valley, going into the heart of the National Park cross follow a passage between, the steep rocky slabs then the track leads to the pastoral cabin (where there is water). The track continues with several bends through alpine lawns at altitude... It follows a wonderful waterfall originating in Vallon lake. The landscape becomes very mineral when you arrive at the first glacial polishes. Return using the same itinerary.
