We stayed there in November 2009 for 2 nights. There were a lot of seasonal vans hidden away in the woods, quite far from the toilets, but the touring pitches were nearer the facilities and the entrance. Standard was fine, pitches were flat and medium sized. Big enough for our 7.95m van.
People who own/run the site live in the house diagonally across the road.
You must go and see the huge sand dune! Bordeaux is interesting too.
