Coral World Ocean Park is arguably the island of St Thomas' premier tourist attraction - and has been enormously popular with visitors of all ages for almost 40 years. The marine park is built on two levels: an over-water floor, with interesting exhibitions, a touch pool, restaurants, and a gift shop; and an underwater observatory, located 15 feet below the surface, where visitors can gape at exotic marine life in its natural surrounds. Coral World also boasts Sea Trek technology - that is, 'helmet diving technology' - allowing you to walk along the ocean floor for up to half an hour with no need for an oxygen tank or a snorkel. This technology was successfully used to stage the first-ever underwater wedding, which took place at Coral World in January 2001.
