Nus highway exit. Enter town and take the road for Saint-Barthélemy. Continue until the Lignan hamlet 1633 m.

A well-known location with mountaineering skiers since part of the “Fillietroz trophy” circuit. The scenery is fantastic with great sun exposure. A trip to the regional astronomy observatory located in Lignan is highly recommended.

From Lignan (1633 m) climb to the top of the slopes. Take the summer path that winds through the wood to the Fontaney chalet at altitude 2,079 m. From here, always to your left, hike to the upper Fontaney chalet at altitude 2,302 m. Cross halfway to the plateaus above. Cross the plateaus to the right of the valley and, following your own path, reach the Salvè hill at altitude 2,568 m. Head West and follow the beautiful peaks on the northern side to Col di Chaleby at altitude 2,683 m.
