Description of the route

When you get to Ferrère, in the municipality of Bionaz, follow the agricultural road that goes to Puillayes, then take route 14 which climbs up in the Montagnayes basin. When you get to the slopes of the Becca des Rayes Plains, turn left on the same itinerary, ignoring route 15 which goes up to Tsa de Culoz-Aquelou, and go up a valley that comes out onto Comba d’Arbière. Cross the valley to reach Alpe Praz de Dieu.
