Takeoff description
refuge altitude: 3450m. This is a climb in itself. With some rock walls, the Amieux cliff and the ascending of the Tabuchet glacier all requiring the presence of a mountain guide. Your effort is well rewarded as the refuge is situated in a climbers paradise, at the foot of the Meije summits and in the middle of the glaciers. duration of climbing: 5h30 vertical: 1800m.
