How to Book Hanauma Bay Reservations: Step by Step
Hanauma Bay requires online reservations for all non-resident visitors. The preserve caps daily attendance at roughly 1,000 people to protect the reef, and the reservation system has been in place since 2021. Here's exactly how to book:
Step 1: Know Your Booking Window
Reservations open exactly 2 days before your visit date at 7:00 AM Hawaii Standard Time (HST is UTC-10, no daylight saving). That means:
- Visiting Wednesday? Book Monday at 7:00 AM HST
- Visiting Saturday? Book Thursday at 7:00 AM HST
- Visiting Sunday? Book Friday at 7:00 AM HST
You cannot book further ahead than 2 days. No exceptions.
Step 2: Be Ready at 7:00 AM HST Sharp
Popular dates sell out in minutes. Here's how to give yourself the best shot:
- Set a phone alarm for 6:55 AM HST (if you're on the mainland, that's 11:55 AM Eastern, 8:55 AM Pacific)
- Load the reservation page at 6:58 AM and start refreshing at 6:59
- Have your party size, preferred time slot, and payment info ready — no time to fumble
- Earlier time slots (6:45 AM - 9:00 AM) fill fastest because the snorkeling is best in the morning
Step 3: Complete Your Booking
Select your date, time slot, and number of visitors. Pay with a credit or debit card. You'll receive an email confirmation — save it to your phone or print it. You'll need to show it at the entrance along with a photo ID.
Step 4: Day of Visit
- Arrive at your reserved time slot — arriving early won't get you in sooner
- Show your confirmation (digital or printed) and photo ID at the gate
- Pay the $3 vehicle parking fee (cash or card)
- Watch the mandatory 9-minute conservation video at the Marine Education Center
- Take the tram or walk down the path to the beach (the path is steep — tram is included with admission)

What If Reservations Are Sold Out?
It happens — especially for weekend dates and the 7:00-9:00 AM time slots. You have two fallback options:
Option 1: Roberts Hawaii Shuttle (Guaranteed Entry)
Roberts Hawaii operates round-trip electric shuttle packages from Waikiki that include guaranteed admission to Hanauma Bay, bypassing the online reservation system entirely. Prices start around $30-$45 per person, and the shuttle solves the parking problem too. This is the most reliable backup plan.
Option 2: Walk-Up Availability
A small number of walk-up entries become available after 9:00 AM on a first-come, first-served basis. The reality: lines form early, and there's no guarantee you'll get in. If you're banking on walk-up, arrive by 8:00 AM and be prepared to wait — or be turned away. Midweek (Wednesday or Thursday) gives you the best walk-up odds.
Best Tips for Hanauma Bay Reservations
- Book Wednesday visits. The preserve reopens after the Mon-Tue closure, so the reef is rested, the water is typically clearest, and there's less competition for slots.
- Grab the earliest time slot available. Morning snorkeling is dramatically better — calmer water, better visibility, fewer people. The fish don't care what time it is, but the sand suspension from afternoon crowds does.
- Have a backup date. If your first-choice date sells out, pivot immediately — don't close the browser. Thursday and Friday morning slots are usually the next-easiest to get.
- Check back for cancellations. Cancelled reservations return to the system. Check the booking page periodically in the 48 hours before your visit date — released slots do appear.
- If all else fails, use Roberts Hawaii. The shuttle-plus-admission package guarantees entry. It costs more than DIY, but it beats spending a morning in a walk-up line only to get turned away.
Getting to Hanauma Bay
Address: 100 Hanauma Bay Road, Honolulu, HI 96825
- From Waikiki: 25 minutes by car via Kalanianaole Highway (H1 East → Highway 72). Turn right on Hanauma Bay Road.
- TheBus: Route 22 runs from Waikiki to Hanauma Bay. About 45-60 minutes, $3/ride.
- Uber/Lyft: $20-30 from Waikiki. Cell service at the bay is spotty, which can make getting a ride home tricky.
- Rental car: Compare Oahu rental car rates. Arrive before 9:00 AM for parking — the lot fills fast.
