A Hanauma Bay day trip takes you to a protected marine area on Oʻahu, where the reef curves around a sheltered bay. From Sweetwater at Waikiki, a Honolulu hotel, the preserve is about 8.3 miles away, with a supplied drive estimate of 30 minutes. Reservations, limited walk-in entry and set arrival and departure times make advance planning useful.
- Location: Oʻahu; the City and County of Honolulu manages the land, while the Hawaiʻi Department of Land and Natural Resources oversees the ocean.
- Typical opening pattern: Wednesday through Sunday, with entry allowed from 6:45 a.m. to 1:30 p.m.
- Admission: Non-Hawaiʻi residents age 13 and older pay $25, plus an online service fee; some groups enter free.
- Reservations: Non-Hawaiʻi residents can book through the city’s PROS system two days ahead.
Getting from Waikīkī to Hanauma Bay
Driving is one way to reach Hanauma Bay from Waikīkī, while Route 22 serves a bus stop above the preserve rather than entering it. The city says bus service into the preserve has been discontinued.
If you’re considering the bus, check where Route 22 stops on Kalanianaʻole Highway and plan for the walk down to the preserve. TheBus’ Waikīkī visitor guide includes Route 22 among its South Shore routes, but does not say it enters Hanauma Bay. The Honolulu Airport-to-Waikīkī transfer guide covers the airport leg before this outing.
Driving does not guarantee a parking space: an admission reservation does not reserve parking, and the lot can fill. The city says you may wait for it to reopen or find legal street parking nearby and walk in. Bring cash for the parking booth, which does not accept credit or debit cards.
Residential-vehicle parking costs $1 for Hawaiʻi residents with qualifying identification and $3 for nonresidents. The fee is refundable if the vehicle leaves within 15 minutes of entering.
Reservations, entry, and visitor rules
Non-Hawaiʻi residents can reserve admission through the City and County of Honolulu’s PROS system two days in advance, with slots released at 7 a.m. Hawaiʻi Standard Time. Reservations remain available until they fill or until midnight the day before.
Admission costs $25 for non-Hawaiʻi residents age 13 and older, plus a 2.35% online service fee. Hawaiʻi residents with qualifying identification, active U.S. military members and dependents with military identification, and children age 12 and younger enter free.
Reservations and payments can cover up to 10 people, with a maximum of five adults and five children; nonresident admission payment is made online to secure the booking.
Hawaiʻi residents with valid Hawaiʻi photo identification can enter free without a reservation during public operating hours. The city accepts a Hawaiʻi driver’s license, Hawaiʻi State ID or Hawaiʻi school student ID as proof.
About one-quarter of access is reserved for walk-in or drive-in visitors. Walk-in tickets are first come, first served, and everyone in your party must be present to obtain one. All visitors must watch the educational video in the theatre on every visit, even if they have seen it before.
The preserve is closed on Christmas Day and New Year’s Day, and its schedule may change. Check the official site before you go; the city also advises calling (808) 768-6861 for the latest schedule.
Planning time at the bay
Plan your arrival around the entry window and the preserve’s required departure times. Entry is allowed from 6:45 a.m. to 1:30 p.m.; the beach is cleared at 3:30 p.m., and everyone must leave by 4 p.m. The preserve is open Wednesday through Sunday.
On arrival, leave time for the required educational video before heading down to the beach. A tramway connects the upper entrance and beach, and the preserve also has a Marine Education Center, educational volunteers and biologists.
Other Oʻahu outings include a Diamond Head hike, which you can plan separately from a day at the bay.
Snorkel rentals are available from 7 a.m. to 3 p.m., with payment by credit or debit card only. Food concessions operate from 8:30 a.m. to 2 p.m. and accept cards only; the gift shop is open from 8 a.m. to 3:30 p.m., also with card-only payment.
If you’re planning another day by the water, Waikīkī Beach access points offer a different setting from Hanauma Bay’s reef-protected shoreline.
Safety, facilities, and conservation
Hanauma Bay is a protected marine area, so visitor rules and conservation measures are part of the day’s plan. It became Hawaiʻi’s first Marine Life Conservation District in 1967.
The city’s management plan, implemented in 1990, aimed to reduce visitor impacts by limiting visitation, improving facilities, establishing an education program and banning fish feeding. The preserve provides ocean-safety lifeguards, bathrooms and fresh-water showers.
Use the lifeguards and educational resources to orient yourself, and follow the preserve’s rules around marine life. For context, the city reports that attendance peaked at an estimated 10,000 people per day in the 1970s and 1980s; average daily attendance in 2019 was almost 3,000.
