The Vanoise massif is a mountain range of the Graian Alps, located in the Western Alps. After the Mont Blanc Massif and the Écrins Massif it is the third-highest massif in France, reaching a height of 3,885 m at the summit of Grande Casse. It lies between Tarentaise Valley to the north and the Maurienne Valley in the south. The range is the site of France's first national park, established in 1963, Vanoise National Park. The ski resorts of Tignes and Val-d'Isère and the 2,770-metre-high Col de l'Iseran are located in the eastern part of the range.
