In reply to metrorat:
Sorry about the various mistakes in my previous post, I should've proofread what I'd written. Also I didn't mean "...you only see" but "you also see".
In terms of crags and routes, that depends, what grade do you climb? I was there with friends who had little to no experience climbing so we didn't do any classic, but even some easier routes are amazing. I think the crag I liked most was Les Vigneaux, one of the upper areas with 3s to 6s (don't have the topo with me but it may be "Les nains"), stunning limestone with multiple layers, a must-see. Just below it there's a fantastic-looking "tower", which I believe is called Trango tower, there's a 6 on it that I wish I'd done.
If you want to combine a nice, easy hike and climbing, Tournoux (I think that's the name) is the place. You have to get to Saint-Vincent 1400, then take the direction of Col de Pousterle. It takes you up a rather rough, rocky road. It's OK if you don't have a 4WD (like us) and you drive slowly. From the carpark at the pass you can hike to Les Têtes, see some "lakes" (ponds really) on the way to the Têtes, from where you'll have a stunning panoramic view as you walk on weirdly eroded limestone (reminiscent of the Burren in Ireland). then come back to the carpark and go to one of the many Tournoux areas; it has everything from 4 to 8.
I suggested Rocher Baron in my previous post but getting there is such a hassle that I may actually not recommend it
But there's plenty of other crags. The Tête de la Draye alone is just a 10mn walk from the campsite and will provide you with lots of routes. Some of the areas are shaded, which is much appreciated when the sun is shining.
If you plan on going bouldering, I suggest you skip the children's circuits as they're polished and way too greasy. Philémon is a nice, shaded area with super cool boulders, like the one by the picnic area. Like I said it's overgraded though, I've onsighted 6Bs even though it's always taken me at the very least 4 tries in Font to do a 6B... There's a great prow in Philémon as you walk down the path, it's simply called "proue - 6b". Nice finishing dyno. The Champignon has some interesting problems too and you pass by it on the way to the Tête de la Draye.
(All of this is very random, I know!)
