Hanauma Bay (HBAY) is not just a breathtaking, world-class snorkeling destination. It is a nature preserve dedicated to safeguarding the fragile marine life in the bay. As the first Marine Life Conservation District in the State of Hawai‘i, several organizations work together to chronicle the environment, educate the public, and conserve the natural resources for future generations! On this website you’ll find resources regarding scientific research done at HBAY, visitor attendance, the education program, and the many organizations who help to preserve Hanauma Bay.

In order to continue striving for a balance between the recreational enjoyment and environmental preservation of HBAY, the Honolulu Department of Parks and Recreation posts monthly updates of the visitor attendance log showing a breakdown of who is visiting HBAY and at what days.
