In reply to kos-d:
I think Tarn is one of THE best crags ive ever been to. I visited Chorro back in 2001 on a road trip and to be honest it was one of the worse venues we climbed at. The approaches were really long, the routes were polished and the walkway was out of action meaning half the routes were out of limits. it felt like a real 'has been' place. Even John Dunne turned up...
If you have a car or a number of cars then Gorge de le Jonte is literally 10/15min drive away from Les Vignes (in the Tarn) and has stacks of 6's. I cant recomend strongly enough the climbing at Tarn if youre in the 7th grade.
There is variety as well at the Tarn with not all the routes being overhanging, however the steeper stuff is in the majority.
In terms of rest day activity we went kayaking down the river from one of the rent places and theres a fair few nice walks etc.
Go for Tarn - you wont regret it.
