The classics of the Aiguille du Midi

The descents of the Couloir des Cosmiques or the Glacier Rond are the most famous steep slopes around Chamonix.
These 2 lines are serious with a slope at 45º and a significant drop of minimum 1600 meters and if the snow cover is sufficient we can even reach Chamonix with a descent of more than 2600 meters.
It is often necessary to use the rope to access it.

The day

We start by climbing to the top of the Aiguille du Midi cable car.
We descend the Aiguille du Midi ridge to very quickly put on the skis and let ourselves slide along the south walls of the Aiguille.
We almost reach the Cosmiques refuge by going up a little staircase. From there we choose one or the other descent.
