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 States), and Val Thorens offers some of the best skiing in the area. It's possible to ski through Meribel to Courchevel for lunch and back within a day, but check the lift times before setting off. The Funitel des 3 Vallées is a lift designed to transport skiers between Val Thorens and the rest of Les Trois Vallées.The slopes are high and mostly north facing, so there's likely to be a good covering of snow well into spring. There are a wide variety of slopes for beginners and intermediates and some challenging slopes for more advanced skiers higher up, including the Cime de Caron, a steep descent from the top cable car.Val Thorens also offers access to some excellent off-piste options, the descents towards Lac du Lou being the most famous. Even the most experienced skiers and snowboarders should hire a guide when going off-piste, both for safety and to find the best snow.
