Most towns / villages seem to have a municipal campsite. We just decided if it was nearly time to stop or if we liked the look of a town and followed the signs "camping municipal" I think.

Most were quite picturesque. They were all within an easy walk of the town centre and I think we paid 14 euro per night for two bikes and tents last summer.

Only one (Mezamet I think) was spoiled a bit by it's proximity to a rugby-club that was having a yoof disco. We slept to the sound of crap music and mopeds being thrashed up and down. I suppose we should have just stayed up a bit later, had some beers and chilled.
