How about somewhere like Chateauvert? Hopefully out of the weather, but none of the associated hassle of the Calanques.
Minor hijack Is Chateauvert a good winter venue i.e. early December? Permadry and in the southern reaches of France makes me think so? And the area generally seems like it might be pretty decent for a winter chuffing trip?
Another hijack... Heard this is a public transport friendly crag, can you get around without a car once you're at the campsite? Plenty of people around driving towards the crag? We can blablacar/hitch to the campsite next week but wont have a car while we're there (for a week or so) - is it a bad idea?
Chateauvert, looks like an hour or so walk in on google maps, but if the road isn't dead quiet it shouldn't be too hard to hitch maybe?
