Originally this naturist camp, was only a camping site next to the town: Agde in the South East France. Then little by little it became a naturist camping site and even nowadays it is an independent village. It is called: Le Village Naturiste / Naturist Village ( literally).
The Naturist Village became a town by itself. There are 2 km (1,3 miles) of beach, a large marina + 2,500 campsites, apartment complexes, hotel, shops, restaurants, night clubs, bars, post office, bank and ATMs, launderettes, hairdressers and other facilities. In all there are about 180 businesses in the village. One can potentially spend an entire vacation without leaving the area and without wearing clothes ( if the weather allows it of course).
I'm a native French person and I live in the South West France and I know Agde, however I never been in this Naturist Village. I visited most of the towns in the East of France, including French Riviera, Monaco, etc..
