Of the 18 Sandals Resorts, there is only one that has a clothing-optional beach.
Sandals Royal Caribbean in Montego Bay, Jamaica has a private offshore island with a secluded clothing-optional beach area. It’s important to note that only a specific section of the island is designated for clothing-optional sunbathing, not the entire island or main resort.
After taking the boat to the private island, the clothing-optional part of the island will be to the left of the dock. There is a small sign indicating where the nude beach is.
None of the other Sandals Resorts have a nude beach. Sometimes women will go topless at some of the resorts but it is fairly rare. In general, management will only say something if other guests complain.
