The Atlantis Submarine and Harbor Cruise is one of the island's most exciting tours. A unique, once-in-a-lifetime experience is yours when you step aboard the Atlantis and take a ride on one of the world's first fleets of recreational submarines. The real submarine will transport you to ocean depths not visible from the surface, covering over a mile and a half of ocean bottom. Blue chromis, rock beauties, yellowtail snapper and sea turtles are among the exotic sea life you'll see swimming through the sea whips, brain coral and pillar coral. A scenic harbor tour of Charlotte Amalie precedes the dive. At the completion of your dive, you'll be awarded an official dive certificate and enjoy a complimentary rum punch. The tour is two hours long; dives leave hourly beginning at 9 a.m. from Havensight Mall, Building 6. There are also weekly departures from St. John.
