Hanauma Bay Nature Preserve is one of Oahu’s most famous marine preserves, known for its clear waters, vibrant coral reefs, and diverse marine life. For centuries, the area served as a recreational and fishing spot for Hawaiian royalty.
As tourism expanded after World War II, Hanauma Bay became a must-visit destination, attracting millions of visitors and placing significant pressure on its fragile ecosystem.
Today, the bay is carefully managed as a protected marine conservation area. To help preserve its corals and marine habitat, visitor numbers are limited, and most non-residents must secure an advance reservation before entering.
There is also a limit. A single booking can include up to 10 people, with a maximum of 5 adults and 5 children.
When Do Hanauma Bay Reservations Open?
Reservations are available 2 days in advance starting at 7:00 a.m. Hawaii Standard Time. Morning time slots can disappear quickly, especially on weekends, holidays, and busy travel days.
Daily ticket availability is limited. Around 400 online tickets are released each day, while the overall visitor system is designed to keep attendance at about 1,400 people per day. This limit helps reduce crowding and protect Hanauma Bay’s marine environment.
The bay is normally closed every Monday and Tuesday. Because of that, booking dates follow the open public days. Always check the current schedule before you choose a date.

How to Make Hanauma Bay Reservations Step by Step
The online reservation process is simple once you know the steps. Be ready before the window opens, especially if you want a morning time.
Access the Official Reservation Site
Use the City and County of Honolulu reservation system on https://web5.hnl.info/pros-ticketing/event/hbay-online-reservation/tickets. Be on the site before 7:00 a.m. HST. Choose your time quickly. Fill out the form carefully. Do not wait if you want a morning slot.
Choose Your Date and Time
Choose the date first, then select an available time. Morning times are usually the most useful because they give you more time and better parking odds.
Select the Correct Visitor Types
Choose the correct categories for your group before checkout. A single booking can include up to 10 people, with a maximum of 5 adults and 5 children. Non-resident adults, children, eligible residents, and qualifying military visitors may have different entry rules.
Review and Confirm Your Booking
Before confirming your booking, review the selected date, time, visitor categories, and payment details. Payment rules, card options, and service fees can change.
Save Your Confirmation and View Your Ticket
You can show your confirmation or ticket on your phone. Take a screenshot of the full confirmation page and ticket details in case the email is delayed or mobile service is weak.
Do Not Refresh During Ticket Checkout
If the payment screen freezes or spins, do not refresh or press the back button unless the official system tells you to. Refreshing can create problems with retrieving the booking.
Who Needs a Reservation?
Most non-Hawaii residents need an online reservation or a walk-in option to reach the beach level. Hawaii residents with valid identification may access the bay during public hours without a reservation. But non-resident guests still need their own valid ticket access.
| Visitor Type | Needed Reservation? | What to Know |
|---|---|---|
| Non-Hawaii residents age 13+ | Yes | Use the official reservation system or check current walk-in instructions if available. |
| Children 12 and under | Free entry category | Still include children correctly when planning your group. |
| Hawaii residents | No online booking required during public hours | Bring valid Hawaii photo identification. |
| Eligible U.S. active military and dependents | May qualify for free admission | Bring valid military ID and check current official rules before visiting. |
| Non-resident guests of Hawaii residents | Yes | Resident access does not cover guests who do not qualify as residents. |
Important resident rule
Hawaii resident access does not automatically apply to non-resident guests. Each visitor must meet the correct entry requirements.
Entry Fees, Payment, and Free Admission
Non-resident visitors age 13 and older are usually the main paid admission category. Children 12 and under, eligible Hawaii residents, and qualifying military visitors may receive free admission.
Do not treat the entry fee as the only planning issue. Availability, timing, and parking can affect whether the visit goes smoothly.
Non-resident adults
Non-Hawaii residents age 13 and older are normally the main paid admission category.
Children 12 and under
Children 12 and younger are listed as a free-entry category, but they should still be included correctly when planning the group.
Hawaii residents
Hawaii residents need valid Hawaii identification to use resident entry rules.
Eligible active military
Active military rules depend on valid ID and official eligibility. Check current rules before visiting.
For the full cost breakdown, read the fees guide.
What Your Ticket Includes
Your confirmed ticket applies to a selected visit date and time. After check-in and the required conservation steps, it allows you to reach the beach during public hours.
Selected visit time
Your confirmation is tied to the visit date and time you selected.
Check-in process
You still need to check in, follow staff instructions, and complete the required visitor process.
Conservation video
Visitors are required to watch the educational video for each visit.
Beach-level access
After entry steps are complete, visitors can access the beach during public hours.
What Is Not Included
A reservation covers admission only. It does not include parking, transportation from Waikiki, snorkel gear, food, drinks, or guided snorkeling.
| Not Included | Why It Matters | Where to Plan It |
|---|---|---|
| Parking | Parking is limited and not reserved with your ticket. | Parking guide |
| Transportation | You still need to drive, rideshare, take transit, or book transport. | How to get there |
| Snorkel gear | Bring your own gear, rent if available, or choose a tour that includes equipment. | Snorkeling guide |
| Guided snorkeling | A guide is separate unless you book an option that includes support. | Best tours |
Most common mistake
Visitors often secure a ticket reservation and assume the whole visit is handled. Parking and transportation are separate, and both can affect whether the visit goes smoothly.
Is Parking Included With a Reservation?
No. A reservation does not include a reserved parking stall. It only covers timed admission to the preserve.
If the parking lot is full, visitors may need to wait until the lot reopens or find legal street parking nearby and walk into the nature preserve. That can take time, so do not arrive too close to your entry time.
Parking is separate and cash only
The parking booth is cash only. Parking is $3 for non-residents and $1 for Hawaii residents with valid Hawaii ID.
Read the full parking guide before deciding to drive.
Arrival Rules and Timing Tips
Plan to arrive as early as possible to park, check in, complete the required education process, prepare gear, and walk down to the beach. Late arrivals can lose valuable beach time.
Late arrivals may sometimes be accepted before last entry, but that does not mean a late start is a good plan. The beach is cleared before the preserve fully closes, so afternoon visits can feel rushed.
Best arrival strategy
Choose a morning time if possible, leave extra time for parking, and avoid scheduling another timed activity right after your visit.
For timing advice, see the best time to visit.
What If Entry Is Sold Out?
If your preferred time is unavailable, try another open day, check for a later slot, or review current official instructions for same-day walk-in availability.
A limited number of walk-in options may be available on a first come, first served basis when the gate opens, except on closed days. Everyone in your group must be present if using that option.
Best backup plan
Do not save the bay for your final available day on Oahu. If availability is gone or ocean conditions are poor, you need another chance.
Could not get the time you wanted?
Compare guided and transportation-included options if you want a simpler backup plan from Waikiki.
View Best Tour OptionsSelf-managed Visit vs Guided Tour
A self-managed visit is best if you already have transportation, a parking plan, and snorkel gear. A guided or transportation-included option may be easier if you are staying in Waikiki or do not want to manage logistics yourself.
| Option | Best For | Watch Out For |
|---|---|---|
| Self-managed visit | Visitors with transportation, parking plan, and gear | Parking, gear, and timing are still your responsibility. |
| Tour with transportation | Waikiki visitors who want simpler logistics | Admission costs may still be separate, so check inclusions carefully. |
| Guided snorkeling | Beginners or visitors who want support in the water | Some options focus on guidance, not full transportation. |

Common Booking Mistakes to Avoid
Waiting too long
Ticket availability is limited. Be ready at the reservation site before 7:00 a.m. HST, 48 hours before your visit date.
Choosing a late time
A late time slot gives you less time for parking, check-in, the video, snorkeling, and walking back out.
Forgetting parking
A ticket reservation does not include parking. If you drive, arrive early and bring cash.
Choosing the wrong category
Select the correct visitor type when booking. If you make a mistake, follow the official instructions.
