St Marc aire near St Nazaire

Interesting aire which is free and has water which i remember to be free, its a tad slopey and remember it as being hard sandy. Its part of one way system so careful which way you exit.
If you take a look at the map you can see it is very close to a beach and if you look further you can see the naturist beach just below.
Fortunately/unfortunately males appear to meet up in the woods just behind the aire and it makes an interesting night if you sit outside your van with a bottle of wine...
