When your cruise ship docks in St Thomas you can enjoy an underwater adventure even without diving certification. Embark on a snuba excursion instead! Enjoy general admission to Coral World Ocean Park along with a 30-minute guided snuba tour. Snuba allows you to breath underwater using a hose and air pumped in from above the water's surface. Following a lesson on how to use the equipment delve into Coki Beach's coral-filled waters, which are absolutely teaming with sea life. Later peruse the park's many other attractions, including an undersea observatory tower.
