Description of the route
From Crêt du Pont, on the road leading to the hamlet of Crépin in the municipality of Valtournenche, just after crossing the bridge, take Alta Via 1 (which for a stretch coincides with path no. 6) which gains considerable altitude among the pastures and after crossing the woods, and after a diagonal slope, leads to several buildings of the hydroelectric power station (Promoron). From here you come to Alpe Falegnon and continue into the valley along the hillside, until you come to the foot of the artificial barrier. At this point, you go up to the right until you are above the barrier; cross it to reach the Barmasse refuge.
