Well, did not mean to open can of worms but maybe good it is discussed?
So, if I understand Sands is just a beach area and there is some area by the mangrove and sea grapes that MAYBE C/O friendly. But at this time no one cares because there is nothing or almost no one there.

Does that about cover it?

When someone discovers that it has potential and some local Frenchmen wants to try and make a couple of euros at renting chairs+ and maybe some snacks it will be taxed and regulated out of existence. So, take a risk for the time being until someone official takes down the signage or condones it. They might be surprised to find a gold mine if they condon and allow some chairs?

Has anyone seen any nudes using the area?
