The Refuge des Cosmiques is an often used hut in the Mont Blanc group and it has an easy access from the Aiguille du Midi.
You have several climbing possibilities so you should book a sleeping place some days before.

From the hut you have a great view to the Col du Midi and the glaciers in this area (Vallée Blanche and Glacier du Géant ), to Mont Blanc du Tacul (with the normal route to the summit), Mont Maudit and Mont Blanc. Grandes Jorasses and Dent du Géant also looks very impressive from the hut. You also see Chamonix 2.000 m below in the valley.

How to get there

Auguille du Midi on the way to Refuge Cosmique

Normally everybody takes the ropeway to the Aiguille du Midi (3.811 m). Every other ascent to the hut is extremely long and difficult.

From the mountain station of Aiguille du Midi you descent in 30 minutes to the hut. First you have to go a very sharp snow ridge (ca. 100 m, normally with a good track, on the right side you will fall to the Col du Midi (3.532 m), on the left side you will fall down over 1.000 m with direction Chamonix).
When the ridge gets wider you turn to the Col du Midi (3.532 m) in a wide arch (crevasses on the right side).

At the end you have to ascent 80 hm to the hut.
The hut is located in the rocks under the Aiguille du Midi.
