Leaving the Suffet Hut we attempted to find the ski line marked on the IGN maps, which proved to be a time-consuming steep bushwhack and completely un-obvious. This involved crossing the Ambin river, using the bridge some way E of the hut. I don’t recommend this, but suggest instead crossing the river by the bridge next to the hut, then attempting to follow the summer trail.

Find your way through the steep ground, doubling back on yourself at about 2140m. Above here it is much easier. Pass by some information boards about the lake and the pass itself, and about Hannibal’s supposed crossing with his elephants a long time ago. From the far side of the lake, near the Lanslebourg lifts, take the traversing track that heads W, gaining height initially, eventually to the top of the Roches Blanches chairlift, then down the pistes to Termignon.
