Southern France Allos/Haute Verdon. The bike park itself is more enduro style tracks than DH and some of the other stuff in the area is just ace (3 awesome descents from the col d'allos. V-topo guide Alpes de haute Provence has loads of routes. My favourite place in the alps great riding, beautiful scenery and guaranteed sunshine.
http://www.pinkbike.com/news/Enduro-World-Series-Round-Two-Val-DAllos-Saturday-Racing.html gives you an idea of what its like.
If you wanted a guide, there is a company called Peps spirit that operates in the area, they are something to do with the organiser of the EWC and they were doing bus uplifts to the col d'allos when I was there.
Capacir/Cardagne in the Pyrenees Orientale is another good destination and Les Angle, Ax Les Thermes and La Molina all have enduro style riding off the lifts as well as good riding outside the bike parks. Weather is usually good as well.
