Description of the route

From the state road for Gran San Bernardo, take the road that leads to Buthier and leave the car in the square at Buthier Gorrey (1375 m). Take a route which soon comes to Clemencey, where the trail joins routes 3 and 3A. Continue up until you reach Alpe Mendey (1547 m). Near the residential area, take route 3, which goes into the woods. You soon come to the private road for Alpe Chez-Tognette, which you leave after a few metres to take the path that leads up alongside the pastures of Grangette. When you get to a crossroad, c. 1715 m, keep to the right-hand branch, which goes past Alpe Meriau Damon (1740 m), and up Alpe Collet (1919 m). From here continue on the right on the trail that covers the Rû Collet channel, signposted 3B, and which, gently winds up the slopes of Cresta Tardiva and enters the Ars valley. When you get to Alpe Ars (1975 m), go down the steep agricultural track signposted 4, until you reach the old military road (3C), near Alpe Praz-Gallet. Turn right and go down the trail until you come to a bend, where there is a no-entry sign for vehicles. Turn right and you quickly come to the pasture of Mendey. Go back down the same trail that you came along to get to the car park.
