Panoramica: Rû - Berriér - Place Moulin

From Rû, in the municipality of Bionaz, take route 3 which goes along and intersects several sections of the dirt road, and leads to the alps of Primo and Berrier. From here, at the crossroad ignore route 4 on the left and continue along route 3, which takes you to La Tsa after going past the alp of Marmottin. Continue along the same itinerary (3) and ignoring route 5 which leads to the valley bottom, you come to Pas des Feuilles then, go past a section of the route with facilities, to reach the alp of Grand Chamin. Near the lodges, take the private road that descends to Chamin and abandons it after a few metres, then regains the route on the left until it reaches the paved road at a hairpin, not far from the Place Moulin dam.
