Les Deux Alpes has several ski schools. L'Ecole du Ski Français (ESF) is the best known.
Besides the group lessons and private lessons, you can also do freestyle training. At the Bureau des Guides et des 2 Alpes Accompagnateurs, you can book ice climbing and off-piste skiing / boarding.
Nearest to the Venosc lift, you’ll find the relatively new ski school: Evolution2. All ski instructors speak English and the groups are smaller. Les M 2 guests get a 10% discount on the group lessons
There are also a number of independent instructors. We can recommend the ski school which suits your needs the best.
