From the top of the Aiguille du Midi we will descend the famous ridge, then we will head towards the Cosmiques refuge along the south face of the Aiguille du Midi. From the start of the route we will walk all along the ridge. Whether it is at the beginning with a steep a little bit inclined, with a rock to go up, then afterwards a rappel to make or still some steps of rock climbing of an easy level, we will finish by an inclined chimney which will lead us in top of the Cosmiques ridge on a small platform, with a superb view with 360°. Then we will head to the terrace of the Aiguille du Midi by a ladder and descend quietly into the Chamonix valley by cable car.
The itinerary may be slightly modified for safety reasons (weather, level of participants) or for organisational reasons.
