Description of the route

Take the agricultural trail signposted 1 at the bend in the regional road near Voisinal, in the municipality of Oyace, and which leads to the historical source near the alp of Challambé. From here, take the trail that goes up on the right, again signposted 1. After crossing a stream, usually dry, you come to a crossroad with a path that leads to the alp of Dzone. Ignore this branch and descend on the left until you come to the regional road. Take this and in a few minutes you come to the hamlet of Thoules di Valpelline.
