St Thomas Nautilus

St Thomas Nautilus

Travel eight feet under the water while never leaving the surface as you view the abundant sea life and coral reefs surrounding Coki Point.

After boarding the Nautilus you will begin your 45 minutes exploration of the magnificent underwater world of St. Thomas. As you cruise around the bay and coral reefs, you will explore the natural undersea coral gardesn packed with myriad colorful tropical fish. Search the grass beds for turtles and stingrays. The Nautilus diver will feed the fish to bring them even closer to your viewing window.

You must be able to walk up and down stairs.
