Hānauma Bay Nature Preserve

Hānauma Bay Nature Preserve is just off SR 72 (Kalaniana‘ole Hwy.) at 100 Hānauma Bay Rd., following signs. The preserve is in a remnant of a volcanic crater notched into the shore below Koko Head. The bay is a popular scuba diving, snorkeling, swimming and picnicking spot.

The Marine Education Center houses displays and interactive exhibits relating to the bay's inhabitants and geology. Implements used by the settlers also can be seen. A brief film about preserving the bay and other similar environments is required viewing.

Note: The collecting of souvenir coral or any other item is strictly forbidden. Use of the online advance reservation system is strongly recommended. At time of publication no shuttles, tour buses or taxis are allowed; use private vehicle, rental car, Uber or Lyft. The parking lot is first come first served and often fills up early; visitors will not be admitted when the lot is full. Snorkeling equipment and locker rentals are available. Weekends tend to be less crowded than weekdays.

Picnicking is permitted. Food is available.
