Aosta Est highway exit. Take the road for Gran San Bernardo, turn right towards Valpelline and, after several km, turn left for Doues. Cross the town and continue as long as the road is clear of snow, usually to the town of Proseille.

Sparse woods, wide slopes and a magnificent basin make this tour unique. This route is also accessible in May or the beginning of June when the road is open to the Champillon mountain pastures.

From Posseille, 1,450 m, climb the fields above heading North-West to the Moffes chalet, 1,953 m, and then to the Arp di Praz chalet, 2,055 m. Go around the base of the Crou di Blenche following the farm road to the Champillon valley until you reach the mountain range at altitude 2,078 m. Continue West to the Letey chalet, 2,297 m. Continue in the same direction climbing the simple route over the canyons to the hill.
