It depends. I'm living in Lyon. Perhaps you know this city.
In general, I go to the following stations : 2 Alpes, Grand Bornand, Alpe d'huez for week-end sessions.
During holidays, I go more in larger stations, like Val Thorens, Val d'Isère or Tignes.
I really would like to travel and ride other mountains but, for the moment, I'm a kind of poor (student life is hard
, especially for your bank account). that's why, finally I exclusively rided in the Alps, because it's close to my location and I can ride a lot at a cheap price.
My dreams will be to ride in Canada, and one day, I'll realize this dream
