How to get here

Aosta Ovest highway exit. Follow the directions for Courmayeur. In Arvier, turn left for Valgrisenche that leads to the village of Usellières, where you can park.

Description of the route

Day one
From Usellières, follow the farm road, closed to unauthorised traffic, to the Saxe Savoie mountain pasture. Continue along the east path that hugs the right bank of the stream and crosses the narrow part of the valley where you will usually find a small snowfield. Climb up the pastures and where you’ll find the Bezzi hut after the grassy rises.
Day two
From the hut, take the path with several hairpins that climbs the slope behind the hut to the Piano del Vaudet. At the edge of this grassy and stone covered area, leave the path and follow a watershed to the moraine on the left edge of the Bassac glacier. Climb the rocks that rise to altitude 2,870 m where the glacier starts. Still on the rocks, keeping to the left of the crevasses, you’ll reach a wide gap at altitude 3,414 m between Grande Traversière and the south Bassac peak. From the depression, cross the easy snow and then rock ridge to the top.

Descent down the upward itinerary.

This itinerary requires experience of high mountains and it is recommended that you get a mountain guide to accompany you.
