Châtillon motorway exit. At the stop, head left and take the fork on the right (in the direction of Cervinia). Follow the S.S. 26 as far as the roundabout for Valtournenche. Carry on as far as Antey-Saint-André. Turn left and you will come to Torgnon and the hamlet of Pecou (1644 m).

Long extending excursion, immersed in very wild surroundings.

From the inhabited area of Pecou at 1650 m, start climbing along the diagonal stretch, crossing the vast pastures in a northern direction, until you come to the carriage road at the Châtelard mountain pastures, 1891 m. Follow the almost flat trail for about 3km as far as the Loditor Lake at 1962 m that can easily be spotted thanks to the vast rock face above. Start climbing up to the left in the direction of the Château mountain pastures at 2084 m and Le Crotte de Loup at 2161 m. Climb back up the steep valley that will quickly take you to the vast sections above and the Erbion mountain pastures at 2522 m. Turn westwards and, along a steeper slope, you will come to a vast ridge. Remove your skis and climb to the top.
