I took a group of 12 out to Morzine at the beginning of july last year. Which was bloody amazing. Had some people on the xc bikes who went off on big mountain adventures, and the rest of us, who either had DH,FR or AM bikes rode all (I say all, there are so many that would have been missed) the Morzines trails, Les Gets, over to Chatel, up to Avoriaz and Also did swiss national track, and Champery world cup track.
Morzine is where it’s at, if you want to be at the heart of the MTB scene whilst you are there, But les gets would still be a good shout if it is cheaper.
When you say mix up…we had a guy ride everything on his orange crush including Champery. You will have an amazing time, no matter what you ride when you are out there. Great mix of trails.
I will be going out for more than a week this year for sure.
I found lots of chalets through chalets direct. (create an account for free, and fill out a form for what you want and how much you want to spend) Chalet owners will email you with their offers. We got a sweet 12 man, for 60 each with a hottub and loads of extras, which was outside morzine. We had a minibus that we just drove to the lifts each day. Worked out pretty well too.
