Vanoise National Park
The biggest concentration of world-class ski resorts in the world is in the Tarentaise Valley . Well known neighbour ski areas are Espace Killy (Val d'Isère and Tignes) and Les Trois Vallées (Courchevel, Meribel, Val Thorens and more). Lift tickets can span across all the areas. There were plans to interlink all resorts, creating the largest ski area in the world, however that vision ended due to the creation of the Vanoise National Park.
