Les Deux Alpes has something for everyone, though its 220km of pistes aren't linked to other ski resorts in the area as some massive French areas are, so it can occasionally seem limited for on-piste skiing... Beginners:
Les Gours is a big long blue run that starts at the mid-Jandri Express station (2100m) and winds down the valley to the bottom of the La Fee chair-lift.
Intermediates:
La Fee, a wide, steep, open red run which is fantastic for intermediate and advanced skiers/boarders who want to descend at pace.
Advanced:
For the most most exhilleratingly and challenging set of runs in the resort, try taking the Super Diable from the top of Tete Moute and hurtling down its steep face, followed swiftly by Les Vallons and Diable 2.
Off-piste:
As you come up on the La Fee chairlift, look down to the left and right and you will see plenty of relatively safe off-piste hills that come off Fee run and the black Aymes.
