Haven't stayed on any sites in that side of the Aveyron - but have been to Rodez in December on a 1p Ryanair flight - do visit Sauveterre la Rouerge whilst in the area - it's lovely - check out the toilets near the 'Mairie' for a mediaeval experience (modern toilets, I mean, but in the most stunning building). It's very rolling countryside there, lovely for cycling, - and there are several Camping Cheque sites, but we tend to stick with the other side of the Aveyron, down around the Millau, Gorges du Tarn area sorry.
