Hanauma Beach, Nature preserve and marine conservation district in East Honolulu, United States
Hanauma Beach is a nature preserve and marine conservation district on Oahu's southeast coast featuring a curved sandy beach nestled within a volcanic crater formation. The site is surrounded by healthy coral reefs and the water remains clear and calm, making it suitable for both swimming and snorkeling.
The area began as a traditional Hawaiian fishing ground and became Hawaii's first Marine Life Conservation District in 1967. This transformation reflected growing awareness about the need to protect delicate reef ecosystems from overuse and damage.
The beach holds meaning for local communities as a place where fishing traditions once thrived and where visitors now learn to coexist with marine life. You will notice signs and guidelines throughout that encourage respectful behavior toward the reef and its inhabitants.
The beach is accessible during daylight hours with periodic closures for cleaning and maintenance. It is advisable to arrive early to avoid crowds and bring water, sunscreen, and sturdy footwear since the paths to the beach and underwater terrain can be rocky.
The waters here support approximately 400 fish species and serve as a nursery for green sea turtles before they migrate to distant atolls. This hidden function as a breeding and rearing ground for endangered marine animals makes the site exceptionally important for species survival.
