In reply to JayPee630:
There's an entry for Ceou on this site's crag directory. I *think* it was the old Rock Climbing in France guide that we used (not at home, and can't remember for sure), but you can get a topo at the campsite, and the short path to the crag literally goes from behind reception. It's near Castellnaud, and is pretty handy for a halfway stop that doesn't feel like a wasted couple of days. Be warned, it gets pretty hot there in the middle of summer, and the crag faces west - so morning cragging. It's also quite high in places and you need a 60m rope to get the best out of it, if not a 70m.
The only downside is that the surrounding areas are heavily infested with rich Brit holidaymakers in their Chelsea tractors; fortunately, none of them camp, so the site at Maisonneuve is very pleasant. Definitely worth a stop - the kids rated it as one of the highlights of our trip last year.
