Descrizione del percorso

Park the car in Bellecombe, a hamlet in the municipality of Châtillon, which can be reached on the road for Ussel, then take the winding private road that is closed to traffic, and go up to Alpe Mont Ros Désot. Here, take the trail (no. 2) to the right, go past a stream and head leftwards until you reach the first ruins of Biolasse, then Alpe Thoule. The slope now begins to increase considerably until it reaches the crest at a mountain pass, on the left of which rises Mount Lyan. Continue on the right along the full length of the crest between the central valley and the valley of Champorcher to reach a long semi-flat section that joins with trail no. 8 from Hérin. From here, go up the wide steep ridge until you come to the peak of Mount Barbeston.
