Hanauma Bay has been Oahu’s most popular snorkeling spot for decades…and for good reason!

It’s largely protected from the ocean and the large reef is home to a huge range of species, some that are only found in Hanauma Bay. It’s also a perfectly idyllic beach to wile away the day.

And that’s a recipe for popularity. After years of abuse and overuse, the state has taken measures to better preserve the bay and reduce the impacts of visitors. 

Snorkeling at Hanauma Bay

Hanauma Bay was declared a protected marine life conservation area and underwater park in 1967. And since the 1990s, they’ve taken steps to educate visitors with a marine education center and a requirement that all visitors watch a 9 minute video about the preservation and safety rules for the park before entering. 

But the biggest changes have happened since reopening after COVID. The bay is now limited to 1400 visitors per day (which is a fraction of the crowds it used to see) dispersed through a reservation system. It also has reduced hours and is closed two days a week. 

Yes, a bit of a logistics headache for vacationers, but after the rest during the COVID closure and the new protocols, the bay is FLOURISHING. 

I jumped through the hoops to get a reservation on my last trip to Oahu (I hadn’t been in almost 10 years), and I was BLOWN AWAY by how good the snorkeling was. 

Seriously. I’ve snorkeled at all of the “best” spots in Hawaii…done all the big snorkel tours…and this was by far the best snorkeling experience I’ve ever had in Hawaii. 

I saw types of fish I’d never seen before, and in such concentrated numbers. 

So yeah…you have to make an effort to snorkel Hanauma Bay (and pay the fee…more on that in a bit), but it is 100% worth it and I think it should be on EVERYONE’S Oahu itinerary. 

Hanauma Bay Logistics

Like I said, parking and entry is limited and fairly, er, complicated, so you’re going to have to plan ahead if you want to visit Hanauma Bay. 

Currently, here are the details: 

Hanauma Bay is CLOSED on Monday and Tuesday to give the reef a chance to rest. 

Closed Christmas Day (Dec 25th) and New Years Day (Jan 1st). 

Daily hours are 6:45AM to 4PM (last entry at 1:30PM, they start to clear the beach at 3 PM, and the gates at the parking lot are closed at 4PM). 

The entrance fee is $25/person (12 and under, active military, and local residents with Hawaii state idea are FREE). 

Parking is $3/vehicle, cash only. But there are only about 300 spots and they’re first come, first serve.

RESERVATIONS ARE REQUIRED for entry, and they book quickly. 

They can be booked online here at 7AM HST two days in advance. They’re limited and are usually gone within 5-15 minutes of the release time. 

Only 1400 people are allowed into Hanauma Bay each day (40 people every 10 minutes). Reservations are spaced in 10 minute increments throughout the day. 

When you make your reservation, you’ll select a specific entry time and then line up 15 minutes prior. So they recommend you arrive about 30 minutes before your reservation so you can find a parking spot and get sorted.

This is a well oiled machine. They won’t even let you down into the parking area if you don’t have a reservation (unless you’re local or you’re arriving first thing in the morning as a walk in).

There are a limited number of walk in tickets available each day if you show up in person when the park opens. If you’re not able to get reservations online in advance, this is your only option. But you’ll have to show up early. 

Locals (with valid Hawaii state ID) can enter for free without reservations between 6:45AM and 1PM daily. 

A few more details: 

Snorkeling equipment, life vests, and chairs are available to rent. You can also bring your own. 

The snack bar on the main level (near the parking lot) is now open (including a small gift shop with beach essentials), but you’re also welcome to bring small coolers. 

Lockers are available to rent down at the beach level. 

A shuttle down to the beach and back is included. It’s a pretty steep walk. 

Things you should bring with you (if you want them): towels, swimsuits, chairs and umbrellas, life vests, waterproof phone cases or cameras, reef safe sunscreen. 

AND BESIDES ALL OF THIS: You’ll also want to monitor the conditions at Hanauma Bay closely before your trip as it’s a pretty delicate ecosystem and the state is really focused on protecting it (and keeping visitors safe). 

While it’s always closed on Mondays and Tuesdays, it can also close spur of the moment due to jellyfish (which sometimes has to do with the tides and moon phases and other times just seems random), and earlier this year experienced a more prolonged closure due to high bacteria levels in the water. 

Is Snorkeling at Hanauma Bay Worth It?

A lot of people (especially people who visited before these rules and protocols were in place) get really irritated that it’s a “hassle” and a “money grab” and huffily say “they’ll just go to other snorkeling spots that are free.” 

Great. Love that for them. 

Look, I understand that this takes planning and some people are adverse to that and don’t like spending money. 

But Hanauma Bay is special. And I 100% think it’s worth planning (and paying) to spend a day here. There are other places to snorkel, but this really is the best (especially as it’s flourishing now since the regulations).

It’s also just such a great beach to spend the day and it’s very accessible (parking, life guards, amenities, etc.)

If you have a group where some want to snorkel and some don’t (or only want to for a short time), this is a great place to spend the day. The beach is beautiful, and it’s fairly easy to find a spot in the shade. 

How to Plan a Visit to Hanauma Bay

You can enter the bay as early as 6:45 AM, but I like to book an entry time around 10:30 AM and do a hike in the area first. 

If you’re wanting to hike either Koko Head or the Makapu’u Lighthouse Trail, both are in the area. 

You would have plenty of time to do either of those hikes, stop at the Koko Marina Center for breakfast at Heavenly Island Lifestyle, Moena Cafe, Napoleon’s Bakery, or Island Brew Coffeehouse and make it to Hanauma Bay by 10 AM. 

That gives you 4-5 hours to enjoy Hanauma Bay, which I think is perfect. Grab a cheap cooler from an ABC Store the night before and bring some snacks and drinks and you’ll have a great day. 

I’ve made it my job for the last 10 years to explore Maui.

And after hundreds of beach days, rainforest hikes, snorkeling trips, and reconnaissance missions to find the best hotels… and mai tais… I put everything I know into one place.

This is my Maui Digital Map — hundreds of my favorite spots. Beaches, snorkeling spots, hikes, farm tours, scenic drives, places to eat.

Yes, I share hidden spots I don’t talk about so much on social media…but also—tourist doesn’t have to be a dirty word. Popular places are popular for a reason.

So I break down what’s worth it, what’s not, where to spend your money, where to save it, and how to avoid crowds at some of Maui’s most popular (and best) places so you actually enjoy your time.

I’m also sharing all of my travel guides on when to go, where to stay, detailed hotel reviews…
plus dozens of itinerary options based on where you’re staying and what you love to do.

It’s everything you need to see the best of Maui and actually relax. A Vacation in a box…all YOU need to do is pack your suitcase.
