Mont Blanc du Tacul Usually done from the Cosmiques Hut, but fit parties sometimes take the first morning telepherique and descend from the 'Midi'.
The Vallée Blanche ski run is a 20 km long, unmarked off-piste ski route which begins very steeply from the Aiguille du Midi station and, because of its complexity across crevassed glaciated terrain and need for route-finding, is best undertaken with a mountain guide [REF].
