We stayed at a camp site in September last year, we were there for a wedding,in Audenge in France it's about 45 mintues outside Bordeaux.
It was very basic, but had showers, loos, washing up and a washing machine and dryer, you had to buy tokens from the reception area to use them. It had a lovely pool as well.
There was a harbour area you could visit and there was also a sea water pool down by the harbour that you could go to, we went once and it was very busy all the locals seemed to be there so very popular.
there were other towns nearby that you could go visit, and there was a huge sand dune that is a tourist attraction nearby, sadly we didn't manage to get there.
It was very quiet, but a nice place, we stayed in a lovely log cabin on the site but there were people in camper vans arriving for the weekend, there were trailers to rent and some people just came along and pitched a tent.
If you're interested I can give you a link to the website, let me know.
