A classic route among ski-mountaineers, but not for the walker, which is a pity because it offers an opportunity to go very high without really encountering alpine difficulties. Map : IGN 3435ET Valloire. Time : 5h. Elevation : 1600 m. The path, not marked on the IGN map, stops around 2900m; the end, fairly steep, unfolds in a more austere mineral landscape. The view on Aiguilles d'Arves, very close and discovered at the last second, is breathtaking. This walk should be avoided very early in season to avoid the spring snow.

Circular panorama from the summit

Start

Park near Bonnenuit, on the Galibier road (signposts). Walk down a little to cross the Valloirette.

Route

The path first passes the Aiguilles chalet (1845m) then goes up the Commandraut valley on the left bank of Torrent des Aiguilles. It slowly gains height in the pastures, magnificent in early summer. Soon the vast mountainside that climbs from the Aiguilles d'Arves hut to the summit is discovered. Around 2100m, traverse Combe du Puy, then Mauvais Pas to reach the Aiguilles hut (2260m).

The path climbs behind the hut (signpost), then traverses left. It is a long and pleasant climb in the grass. At about 2850m, the grass disappears and rock prevails; follow the numerous cairns along the route and avoid the boulder zones under the summit slopes. The best route passes under the summit to reach the north ridge, which is then followed to the top. You can also climb directly under the summit, but the loose shale is not pleasant (desultory tracks). On arriving, the east faces of Aiguilles d'Arves appear suddenly, very close and unexpected. The panorama is exceptional and rewards the long climb from the hut. Descend the same way.
