This route is a good afternoon warm up prior to commencing a more committing day after staying in the hut or as an easy add on to a morning of climbing. Follow the snow ramp up to the left, turn right and scramble across the ridge toward the refuge. There is one down climb rated 4b (about 5.6-5.7). Can be done easily in mountain boots. A few slings from a standard alpine rack could be used for protection although likely unnecessary. Simul climb or solo. Possible to descend the down climb with a short rappel. Route ends on the refuge terrace.
From Aig. du Midi walk down to the Col du Midi and approach the Refuges des Cosmiques. Move SE along the ridge until there is an obvious snow ramp leading up to an easy scramble.
A few slings. Easy alpine.
