In reply to Lubo: It really is amazing what some people say on here..
La Grave would be a desperate, unforgiving and lonely place to learn your off piste trade.
Cham is a completley differnt ball game. It's super easy to drop into the scene, and thousnds do it every winter, largely living from hand to mouth.
Its also possible to find your own ski level. Cham has super amounts of interesting off piste to explore without any big mountain commitment. Many folk skill up this way. I did...
Just do it. You wont regret it.
Ive 12 Cham winter seasons under the belt by the way.
