Hanauma Bay History

Hanauma Bay was declared a protected marine life conservation area and underwater park in 1967 and is home to over 400 species of marine life.

The Hanauma Crater was created about 32,000 years ago, a series of volcanic vents opened along the southeast shoreline of Oʻahu.  Wave erosion eventually cut through the low, southeast wall of the crater, forming the current bay.


Today Hanauma Bay offers a pristine marine environment. Voted the Best Beach in the United States for 2016  volunteers have a booth located on the beach level to help visitors learn about conservation of the reef and the types of fish that live there.

In 2002 a marine education center was opened for visitors and part of the conservation plan, it requires first-time visitors to watch a short video before entering the park so they can learn about the marine life, preservation and safety rules for the park.

Do not stand on the coral.
