^^ what he said.
this thread is fuck old but some reactions.
Cytane at the time of your post the French top 3 parks according to SNOW and SKIEUR MAGAZINE the biggest French freeskiing and snowboarding magazines:
1. Les Deux Alpes
2. Avoriaz
3. Meribel
Val d'Isere got rated somewhere in the middle with a reasonable park and Tignes all the way at the back, obviously. So don't spread bullshit. Past season the French top 3 was divided among Les 2 Alpes, Avoriaz and Les 7 Laux.
As for Les 2 Alpes being only good for park, easy: La Grave. It doesn't get more legendary in France.
If you want Chamonix without the crowds go to Alagna (Monte Rosa Ski) it owns every resort mentioned in this thread for freeriding and the Monte Rosa is the biggest mountain massiv in the alps. And it's in the middle of nowhere.
And there's a shitload more, famous (Zermatt, Saas-Fee, Engelberg, La Grave, St. Moritz, St. Anton) and less famous (Disentis, Les Diablerets, Ovronnaz, Zinal, Grimentz, Blatten, Hoch-Saas...) Don't waste your time zealotting for 1 mountain, just ride as many as you can they all rock.
