In reply to The sharp end:
You can probably hire them in Florac or La Roziere/Peyreleau. The gorges are a stunning ride.
Also;
go vulture watching in Gorge de la Jonte;
make the drive to the Gevaudan wolf park, outside Marvejols;
drive over the Millau viaduct;
buy wine from Clermont-l'Hérault;
go up Mont Aigoual;
try Seynes, if it is sunny anywhere it will be sunny there;
have a day at the Med, Sete is a personal favourite but plenty of other places.
