Just back from a week in Chamonix, where end of season conditions were great. There's good snow cover so the skiing is good, but it's warm enough to climb rock in the sun.
We traversed the Aiguille d'Entreves, which is a quality rocky PD ridge. Approaching on skis from the Aiguille du Midi, we skied out down the Vallée Blanche
Another day climbing perfect rock on the Midi south face. Ideal climbing temperature, and we had the crag to ourselves for the Rébuffat route, about British HVS. This route is easily approached in 5 mins on foot from the lift, and finshes with a short abseil back in to the lift station. Bolt belays, but you need a small rack too.
