This harborside marine park—the creation of New Zealand's most celebrated undersea explorer and treasure hunter—offers a fish's-eye view of the sea. A transparent tunnel, 120 yards long, makes a circuit past moray eels, lobsters, sharks, and stingrays. In Antarctic Encounter, you enter a reproduction of explorer Robert Falcon Scott's 1911 Antarctic hut at McMurdo Sound, then circle a deep-freeze environment aboard a heated Sno-Cat (snowmobile) through a penguin colony
and an aquarium with marine life of the polar sea. You emerge at Scott Base 2000, which has a copy of the Antarctic Treaty and flags of all the countries involved as well as scientific research equipment currently used in Antarctica. You can also dive with the sharks after taking a course or feed various fish.
