Description
This walk to La Bosse de Clapouse, manages to unite the mildness of the larch forest, the coolness of the ravines, and the dimension of the high mountain all in an environment of emblematic plant life. "In the enchanting light of the larch undergrowth, mesmerised by the playful tree keepers that searched the tree trunks at breath taking speed looking for the odd insect that might be hidden in a crack of the bark, I had not even noticed the female grouse that was resting on a low branch. We spotted each other with mutual surprise. The magic led to the noisy departure of the bird. I was the trespasser" Christophe Albert, warden in the Vallouise area From the car park, walk up the Sélé valley by the footpath that follows the left bank of the Celse Nière stream. - At the post, 1572 m, cross the footbridge over the stream to the left. (It is taken down from November to June) Go up the right bank of the stream by the Clapouse footpath, then head diagonally to the left to meander up the slopes alternating through larch and green alder. The route then ingeniously leads to the ledges and crosses ravines before coming to the Clapouse valley. La Bosse (the bump) is the small summit that is reached by following a footpath. - The return trip is made by the same itinerary in the opposite direction.
