Know this site well but have never stayed there, although my sister has. Its a nice site over looking a lake and quite high up, don't let this put you off. Last time I was there (visiting my sister) it was quite open with out much shade. It has a nice bar and swimming pool. There are some nice cycle routes and walking paths to follow. The area is nice too. The nearest beach is about 20 mins drive but we've always gone a bit further to St Gilles, the beach there is great and quite safe for younger children. If you have older children that like it a bit rough or enjoy surfing then Les Dunes is the best place to go. My sister recommends this site very highly although we've always gone to a site not to far away. La Garangeoire
Hope you have a lovely time where ever you end up.
