There were three cases of indecent exposure, one involving visitors who were bathing in the nude at Shoal Bay and who were advised that it was an illegal practice in Anguilla. I have never seen a nude bather on Anguilla ; but lots of topless bathers on Shoal Bay and more occasionally on Cove, typically on day trips from St. Get the binoculars!! Only kidding, i have never seen any nude sun bathers on Anguilla but if i did i would just ignore them I would assume they did not know better. Thus, I would gingerly approach and politely say "you might want to cover up. Any form of nude bathing is against the law in Anguilla and you will be arrested if the police catch you," Then, I would go about my business.
Just to clarify- Anguilla requests no nudity across the island. I have seen it posted a lot, yet saw someone topless on SBE and could tell it was uncomfortable for many around. Martin allows topless so I recommend that if it is a big deal for you.
Making an Anguilla vacation ideal. Anguilla is a short eight-minute flight or minute ferry ride from St. Your total travel time depends on where you hail from, but you could leave the East coast in the early AM and be in the Caribbean sun by late afternoon.
