Les Trois Vallées (French pronunciation: [le tʁwɑ vale]; "The Three Valleys") is a ski region in the Tarentaise Valley in the Savoie department of Southeastern France, to the south of the town of Moûtiers, partly in Vanoise National Park.

Les Trois Vallées has 183 ski lifts, which can transport 260,000 skiers per hour.

[6] As implied by its name, the area originally consisted of three valleys: Saint-Bon, Allues, and Belleville.

A weekly lift ticket in Les Trois Vallées used to allow one to ski one day in each of the other two systems mentioned although this has now been removed.

There were once plans to interlink all systems and resorts to create the – by far – largest ski area in the world.
