The climbing area is referred to as Gorges de L'Aveyron. St. Antonin is the town at the NE end of the Gorge. It's a beautiful place and well woth a visit. You can get the guide book from the tourist office in St Antonin.
As you drive up the Gorge, you will see the many climbing areas like this one which I think is part of Le Capucin
I went to Manjo-carn which has about 160 routes ranging from 4 to 8c+ It also has easy access with a bar and swimming hole at the foot of the crag. A very easy place to spend time.
I reckon you could do some "shallow water bouldering" on that too.
