Just to have my half-pennyworth... I totally enjoyed the South beach this July, and only ventured North once. The naturists were sometimes a bit near to Graziella for everyone's wishes (didn't bother me - I stopped a few hundred yards later and had all the freedom I wanted) but something that could cause trouble. It has in the past.
For me it is just a celebration of tolerance, freedom, and a most glorious sandy beach where I can be safe and content, and paddle in the shallow sea. What more can one ask for, North or South?
