In reply to Dom Mackenzie:
There are a huge number of routes in the Aiguilles Rouges buddy. There's also only one snow patch below the Gaspard. You can avid this by climbing on the Brevent, Tour Crochues, and the Veuilloz (next to the Perrons) with lots of trad, mixed ,or bolt options.
The Blatiere and the Peigne are also approachable on the North side of the valley, and are snow free, but the approach to the former is a bit rubbly tricky..
