Description of the route

From the centre of the village of La Thuile, go down along the street that flanks the Dora Verney until you reach a bridge which crosses over to the left. A trail leaves from nearby an old hotel, which intersects the bends on the paved state road and leads to the village of Pont Serrand. Just before reaching the dwellings, take a paved road on the right which rises sharply and, after several hairpin bends, leads to the pastures of Monquet and Porassey. The now dirt road begins to climb gently up the valley, mid-slope, until it reaches the pastures of Berrio Blanc Inferiore and later Chavanne Inferiore. The slope now becomes steeper, and after a few bends, the road reaches the pasture of Chavanne Superiore and then continues gently until it joins the path that leads to Col des Chavannes.
