Make your way to the east end of St Thomas and board your semi-submarine at the dock near Coki Beach. This partially submersible vessel allows you to view the vibrant underwater world from the dry, air-conditioned comfort of a boat. Find a spot on the upper deck for a view from above the water, or head down below to the ship's 40-window underwater viewing room. 

Learn about this underwater habitat teeming with marine life from your naturalist guide, as well as some history about the US Virgin Islands. Pass shipwrecks and keep an eye out for stingrays and turtles. Watch schools of tropical fish congregate around the boat as the staff conducts a live fish-feeding demonstration. 

Guests of all heights and ages are welcome on this tour, making it a family-friendly option for exploring St Thomas' marine environment. Watch as a professional diver operates an underwater camera, streaming the live feed to the boat's monitors. Enjoy the up-close diver's view of the spectacular seascape without needing your own SCUBA certification. 

The boat will return to the dock after an hour of exploring the ocean. With your admission ticket, discover Coral World Ocean Park's attractions at your own pace.
