Go for a snorkel at Hanauma Bay Hawaii, one of the most popular natural attractions in the world! While Hanauma Bay snorkeling you'll spot schools of colorful fish and perhaps even dolphins and turtles. The safe inner reef is perfect for children and beginners, while the more challenging outer reef will thrill advanced snorkelers on Hanauma Bay tours. Hanauma Bay Oahu Nature Preserve is a natural crescent beach in the sunken caldera of an extinct volcano. The bay is protected by the volcanic formation and the waters are famously clear, providing the ideal environment to spot fish and other marine wildlife.
The City and County of Honolulu's Marine Educational Center at Hanauma Bay Hawaii features marine displays of wildlife in the bay, an educational video theater and other facilities. It's mandatory that you watch the video in order to be informed about the bay's geological and historical background before taking Hanauma Bay tours, and the importance of protecting Hanauma Bay for future visitors.
