Make your way to dock at the Marriott Frenchman's Reef to board the 54-foot (16-meter) 'Cat' for your 3-hour sailing and snorkeling excursion.
Find a comfortable spot on deck in the sun or shade. Meet the friendly captain and crew as you sail into the azure waters and watch the shoreline of St Thomas recede. On your way to the uninhabited Buck Island National Wildlife Refuge's Turtle Cove, get fitted for a snorkel, mask and flippers if you're interested in snorkeling. Alternatively, you can choose to lounge on board the boat or take a swim.
When you arrive at your destination, don your equipment and dive in. Admire multicolored coral reefs, inhabited by an abundance of tropical fish. Watch the Virgin Island's resident Green Sea Turtles gliding along, munching on the plentiful sea grasses.
After snorkeling, climb back on the catamaran for snacks and drinks - fruit and vegetables, water, a variety of non-alcoholic beverages, alcoholic cocktails, wine and beer. Relax on the way back to the dock, enjoying the Caribbean sun and breeze.
Finish your tour after 3 hours and walk away with a complimentary pirate temporary tattoo to show for it.
