The Seaworld Explorer is a state of the art air-conditioned semi-submarine originally used for research on Australia’s Great Barrier Reef. The vessel remains above sea level at all times and accommodates up to 34 passengers comfortably in its hull, which sits 5 feet below the surface. Huge glass windows provide spectacular views of the many different varieties of corals and fish which Curacao is famous for. In fact, the fish come right up to your window, making it easy to snap that memorable photo. The tour is ideal for the entire family and includes entertaining and educational narration from a professional guide, plus a diver swimming alongside the submarine feeding the fish. No scuba or snorkel gear is needed.
