In reply to Elsier:
how about Ailefroide you said you liked Granite? I think september here is amazing for climbing, and there is plenty of single sports routes as well including the Durance valley there are 4 different rock types and over 3300 routes,
as for weather september is normally good last few years, hot but not to hot, having said that it is the mountains so never 100% but where is?
i live in the durance valley 20 mins from Ailefroide, if you would like any more info please drop me a email, Rob@dream-trails.com
cheers Rob
