Oops, sorry. Although not a c/o resort, we did stay within walking distance of Grand Saline beach in a little inn with a nice pool where we could be nude because our group filled the place, i.e. we "nudified it". I think it was called Saline Gardens but I checked and don't see a place with that name. It may have changed it's name to
Fleur de Lune. One just has to be dressed between the inn and the beach. The description sounds like the place where we stayed:
"Nestled in lush vegetation, La Maison Fleur de Lune is the expression of luxury, authenticity and refinement. Let yourself be enchanted by the softness of the fine sand and the colour of the turquoise waters of the magnificent wild beach of Saline, which is accessible on foot.
Fleur de Lune has received the prestigious Green Key Label for its commitment and the promotion of eco-responsible tourism. We look forward to seeing you for an unmissable stay in our house with its 4 lodges, 2 villas and 2 bedrooms. You can privatize this popular place for your events (wedding, birthday...)."
It was very nice then (2012) and from the photos on the website it seems even nicer now.
