Traversée Miage - Bionnassay - Mt Blanc
Physical Level 5  
Technical Level 5  
Number of days : 5

This long passage that leads to Mont-Blanc allows a complete immersion in altitude during 3 days and is one of the best ways to reach the summit of Europe. After a day of approach  to reach the Conscrits hut from Val Montjoie, the atmosphere is both wild and aerial. Two consecutive days in altitude, on the thin ridges of Dômes de Miage, Aiguille of Bionnassey and the Bosses ridge…A great altitude course might look like climbing the summit of a high Himalayan peak !
