The Trois Vallées ski area is one of the best and most extensive in the world (10 times larger than Vail, the largest ski resort in the United States), and Courchevel offers arguably the best skiing within the area - the snow is more reliable than Meribel, which gets more sun. There are lots of easy slopes for beginners beneath the Saulire cable car base station, and there is lots of choice for intermediates in both Courchevel and neighbouring Meribel. Advanced skiers will enjoy the reds and blacks above La Saulire; there are also some challenging north-facing slopes above Val Thorens, which can be reached within a day's skiing. Snowboarders will find some great slopes for cruising and some exciting couloirs for experts. When the snow is fresh there is some good off-piste, but it is advisable to go with a knowledgeable guide. There are several good ski schools in Courcheval, in addition to the state-run ESF, such as New Generation which has offices in both Moriond and Courchevel 1850.
