Grande Casse

The Grande Casse (3,855 m) is the highest mountain of the Vanoise Massif in the Graian Alps in the Savoie department, France. It is located in the heart of Vanoise National Park, near the village of Pralognan-la-Vanoise, which is about 25 km south-east of the nearest town, Moûtiers. It has a steep 600 m high north face. The other sides of the mountain are more gentle, mostly consisting of broken rocks. A high ridge connects it to the nearby peak of Grande Motte. The ridge connecting the Grande Casse and the Grande Motte is the watershed between the Tarentaise Valley in the north and Maurienne Valley to the south.

Climbing
Despite its height it has a relatively easy normal route to the summit. Climbers usually start from the Les Grands Couloirs glacier and ascend the south-west side of the mountain. The north face is an extreme skiing destination.

The first ascent was made by William Mathews along with guides Michel Croz and E. Favre via the south-west face on 8 August 1860. The north face was climbed on 6 August 1933 by the Italians Aldo Bonacossa and L. Binaghi.

The Refuge Félix Faure (2,516 m), used for the normal route, is located at the Col de la Vanoise.
