East St Thomas - Coral World Ocean Park

Coral World is a very popular attraction on St Thomas featuring an underwater (15ft/5m) observatory, a tropical nature trail, the Marine Gardens Aquarium, and an 80,000 gallon circular, glass-enclosed coral reef tank. The entire marine park covers 4.5ac/1.8ha and also includes an open-air shark tank, touch pool, turtle pool, and a mangrove lagoon. Wild iguanas roam the park.

Another attraction within Coral World is Sea Trekkin', an underwater walk on the floor of the Caribbean Sea with depths reaching 12ft/4m to 30ft/9m. Participants wear a special helmet that allows breathing and communication with a guide leading the walk along a handrail.
