Description of the route

From Étirol (1598 m) take the dirt road (no. 107 / 7) that goes into the valley upwards, walk by the summer pastures Chanchevellaz (Tsantsevella) and go on to the little lake (no. 105), cross the torrent and continue along another dirt road (no. 1) as far as the Beutsôloz pastures. Follow the private road (no. 1), and leave it on the left to take the path that leads to the ruins of Hospice de Chavacour. At the crossroad near the ruins, take itinerary no. 5 on the right, which soon leads you to Alpe Château. Cross this road and continue along itinerary no. 5 until you come to another crossroad. Here, ignore the branch on the right which leads to the Rivolta bivouac, and follow the branch on the left which, after crossing the dirt road again, takes you to the pasture of Crot-du-Loup (Cro du Loï). From here, continue along trail no. 3 towards the Tsan bivouac. Before getting to this bivouac, take the right branch at a crossroad (route no. 3), ignoring route no. 4 on the right. Continue in the direction of Alpe Erbion and from here, to Cima Bianca.
