A visit to Hanauma Bay has to be included in your Oahu visit. Once a spot only accessible to the Hawaiian royal family, it is the prime spot to find fish and turtles while snorkeling.
The Hanauma Bay Nature Preserve is one of the world's most unique natural environments.
Within the Hawaiian Islands is a volcanic crater that the Pacific surf opened to the sea, creating Hanauma Bay. The volcano's floor is now a living reef.
Both local residents and visitors from all over the world come to Hanauma Bay to observe hundreds of species of fish and other marine organisms in their natural environment. Over the years, Hanauma Bay has become such a popular place to observe Hawaii's marine life that the Preserve is visited by thousands of people daily.
This constant and intense visitation threatens the environmental and ecological balance of the bay and its marine life. To help protect Hanauma Bay, a group of concerned citizens formed a nonprofit organization, the Friends of Hanauma Bay.
