In reply to snoop6060:
Obviously loads to go at, but plan for it still being really hot (too hot?) to climb in the sun. I went down to Chateauvert last week and was surprised at how uncomfortable it still was. If you do go there, drop your partner off first before parking 1km away from the crags, at either end of the valley as you can no longer leave vehicles as close as you used to be able to.
Sisteron would be a good place to initially aim for, just off the motorway, with a nice camp site just out of town. Drift on from there after trying nearby Orpiere and if it is still too hot, head up to the clearer air in the Briancon area (2 hours away).
