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.^[2] 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.
