Today for acclimatization, we climbed with Eugene and Janna at the route Arête des Cosmiques (Aiguille du MIDI). This is one of the most popular ridge routes in the Mont Blanc massif!!! Climbing with crampons on rocks is another activity, especially when you do it for the first time. But our friends managed it with great success!!! Good job!!! And tomorrow- on Gouter and then to the summit!!!
