For those wanting an active adventure on the water, Captain Alan’s Boat Charters offers snorkeling as well as clothing-optional boat trips. Their Snorkel and Beach excursion allows you to experience four hours of snorkeling and swimming around St. Maarten, Pinel Island, and the uninhabited Tintamarren while riding in one of their 30- to 38-foot off-shore power boats. Enjoy a swim with tropical fish and sea turtles, and then head back onto the boat for snacks, an open bar, and music. Captain Alan’s Boat Charters also offers a 6-hour adventure, trips to nearby Anguilla and St. Barth’s, and a clothing-optional nude cruise.
