Just be aware that Rockfax has terrible practices in the world of guidebooks, they often straight copy from local authors without bothering to climb anything, and don't contribute to any local bolting efforts. Quality of the information is very variable. If you tell me which area you are interested in, I can find which "real" guidebook covers it, though it might be in French.
Thanks for the heads up. I'm planning on hitting Verdon Gorge and Les Calanques and then heading west/southwest. I was really just hoping for the more general guide as an overview of the entire southern region in case there's anything else that looked interesting. I'm starting in Chamonix so we'll be lugging a lot of gear around for the rest of the trip. I was hoping to avoid adding several individual guidebooks to it. If you know the area and have any further recommendations I'd be psyched for them. Trad or sport.
Hum yes, there a few hundred thousand routes down there... Some of the major spots beside Verdon/Calanques would be Annot (sandstone crack climbing, pretty unique in Europe), Orpierre, Buoux, Céüse, Presles, Gorges du Tarn/de la Joux and Châteauvert. Maybe also look at Mont Aiguille on your way south from Cham, it's a very fun and unique summit. You would need a couple of lifetimes to remotely exhaust climbing potential of these.
