Vanoise National Park
The Tarentaise Valley has the largest concentration of world-class ski resorts in the world. Most well known neighbour systems are Paradiski (Les Arcs, La Plagne) and Les Trois Vallées (Courchevel, Méribel, Val Thorens and more). There were once plans to interlink all systems and resorts to create what would have been by far the largest ski area in the world. However, that vision was ended with the creation of the Vanoise National Park.
