In reply to petewimbush: I've just got back from a 2 week trip to Gorge du Tarn/Gorge du Jonte. We camped in Le Rozier as it's handy for both the areas and used the municipal site, which has a swimming pool. There are 2 sites next to it which may be cheaper as well as another one the other side of the river. It gets very hot this time of year, so you'd be advised to climb early morning and in the shade, assuming its sunny. The tabac and souvenir shop in Le Rozier both had guides to the area at 22 euros per guide. The Gorge du Jonte tends to require longer walk-ins and as the guide books only have rather poor black and white photos it can take a little while to find some of the climbing spots.
