Day 1 - Hike up to the Refuge Couvercle (2687 m)
From the Montenvers station (1913 m) we descend to the Mer de Glace glacier and hike up to the junction of the Mer de Glace and Lechaux glaciers. We climb the ladders of the Egralets to reach basin of the Talefre and the hut. (3-4 hours)
Day 2 – Ascent of the Aiguille Verte
We leave at 01am to hike up the glacier of Talefre to reach the base of the Whymper couloir. The couloir has an inclination between 45/50 degrees and a height of 700 meters. The couloir will lead us to the final part of the ascent – a stunning snow ridge by which we reach the summit of the Aiguille Verte with the first daylight .
The descent is by the Whymper couloir – mainly abseiling with some down climbing (10 - 13 hours).
