In reply to Duncan Disorderly:
There are lots of crags in and around the Gorge du Loup not far from Nice, even a very nice multi-pitch venue with some good routes.
Had a similar wet trip to the Verdon a few years ago and we went to Chateauvert for a few days which isn't too far from the Verdon and has a wide variety of grades and styles. There is a very good municipal campsite not far from the crag in the village of Correns.
