Hanauma Bay


Hanauma Bay Nature Preserve is among Hawaii’s most pristine natural resources, rich and vibrant with a staggering array of marine species. In 1990, the City & County of Honolulu developed a plan to protect and preserve Hanauma Bay, which by then had suffered environmental degradation caused by three million visitors per year. That plan culminated in the 2002 opening of the Marine Education Center, which welcomes visitors with a video presentation encouraging them to participate in the stewardship of the precious nature preserve. Today, up to 3,000 people visit Hanauma Bay daily.

Unlike other beaches on Oahu, Hanauma Bay is not a “beach park” intended for ocean sports activities. Rather, it is a nature preserve intended to protect a fragile marine ecosystem. Hanauma Bay is the first Marine Life Conservation District in Hawaii.

In addition to its cherished biological diversity, Hanauma Bay Nature Preserve is also an important Hawaiian cultural site. A 1952 archaeological study discovered evidence of ancient campfires and tools in a shelter cave behind the beach. Although it is unlikely that ancient Hawaiians lived at Hanauma Bay, due to the hot, dry climate and lack of fresh water, it is certain that they fished there. The bay was used by the native Hawaiian nobility as a recreation, entertainment, and fishing area.
