Description of the route

In the square in Valpelline take the road that runs along the cemetery and goes under the hydroelectric power station, and reaches the bridge over the Buthier. Cross it and take route 5 as far as a dirt road. When you get to a crossroad before the residential area of Ranchéaz, turn right onto the road that leads to the pasture of Grangette Désot. Before the houses in this hamlet, take the path on the right, then continue in the same direction, ignoring the mule track to Grangette Damon, and continue until you get to Billiouc Damon and then Billiouc Désot.
