The Alpe d’Huez Grand Domaine pass covers the whole ski area including the neighboring villages of Villard-Reculas, Vaujany, and Oz en Oisans. A 6day+ pass also gives a day’s skiing in the resort of Deux Alpes and Serre Chevalier and you can add a supplement to give you access to the sports center, outdoor (heated!) swimming pool, and the ice rink. There are discounts for family passes and there are also beginner passes available.
There is night skiing available which is included on your lift pass.
Cross-country skiers will also need a pass to access the trails.
