Do I need a passport for shared snorkeling tours or sunset sails? No passport is required for our Buck Island & Water Island Turtle Snorkel, our St. John Snorkeling Trip, or any of our St. Thomas Sunset & Dinner Sails, as they remain entirely within U.S. Virgin Islands waters. A valid passport IS required for the shared British Virgin Islands (BVI) trips to Jost Van Dyke and Virgin Gorda.
