In reply to M.Muncaster: We went there over the summer a couple of years back and although it was hot, we climbed every day. Skin was a tad sore though. Loads of great spots and not too many people. The camping at la grille was great though I heard the campsite had changed ownership
The place mentioned down head ax le therms was good but very moquitoey and unpleasant after a while which was a shame. Worth a visit though
