Hanauma bay nature preserve

Formed within the crater of a volcano on the island of Oahu, Hanauma Bay is a unique protected bay, which has been popular with snorkelers for a long time. After overuse caused pollution and damage to the delicate reef ecosystem, restoration efforts have restored the bay to its original splendor, and it is again open to visitors. The Hanauma Bay Education Center is a great place to learn about the bay, and there are several snorkeling rental shops that offer lessons, so that visitors can see the breathtaking reef system and its inhabitants up-close.
