How to get here
Aosta East motorway exit; head in the direction of the Great St. Bernard Tunnel, as far as the square at the Crevacol ski-lift facilities.
Description of the route
Park your car in the square at the Crevacol ski-lift facilities and follow the road that passes under the viaduct then pass on the left side of the river.  Follow the estate road for a stretch, then head up to the left as far as an Alpine Hut and pick up the inter-estate road.  Follow it, cutting across it in certain parts along pretty slopes as far as the Bois Bas mountain pasture.  After a while, cross over to the left between the larches and climb up the vast valley in the direction of the pass with a non-obligatory route. 
 Descend the upward itinerary.
