We would advise all beginners to have lessons but everybody can benefit from some time with an instructor. You can have lessons at ESF (National Ski School) or with a private instructor. With both there is the option of individual or group lessons.
The ESF offers good value instruction and has offices at every ski area. They have set out to change the old image of the 'French Ski School' and, from our experience, it is working. The number of English-speaking instructors has increased and so has the standard of service. We can book your lessons and recommend instructors. ESF web site.
