gorges du tarn
supposed to be awesome...tons of great climbing
http://www.grimporama.com/francais/images/ph_tarn.htmjust google it....you could check on cosiroc/ffme websites too....
i keep hearing how good it is...but havent ever been...i think the cover of the current petzl catalog is a shot from the tarn actually....
its only about 2 hrs east of toulouse....so i'd guess its no more than 4 hours from pau/tarbes....depending on where you are in the pyrenees it could be closer....
