This work, centered on the Vanoise, is delimited by the wild Belledonne, the large glaciers on the border of Italy, the prestigious Mont-Blanc massif and the warm limestone of Cerces. Very snow-covered, easy to access from the Alpine metropolises, sometimes surprisingly protected by a clearing of foehn, this region is a ski paradise. So much so that the largest equipped ski areas in the world have taken up residence there. But space enthusiasts can rest assured, this guide invites you to discover unsuspected wild valleys, with 134 routes, around 250 major variations and other suggestions, from easy running to steep skiing.
