Hanauma Bay Nature Preserve

Formed within a volcanic cone, today Hanauma Bay offers a pristine marine ecosystem after the City and County of Honolulu laid out a plan in 1990 to restore the bay, after years of use from the millions of visitors who visit and love to snorkel Hanauma Bay. Voted Best Beach in the United States in 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.
