Hanauma Bay Snorkeling – The ULTIMATE Guide

(This guide is regularly updated with the most up to date & accurate information)

Hanauma Bay is one of Oahu’s top 3 places to visit and with around 1000 visitors per day it is one of the world’s most popular snorkel destinations!

Here is everything you need to know when it comes to snorkeling at Hanauma Bay!

Why We Love Snorkeling Hanauma Bay

Hawaii Hanauma Bay protected marine life conservation area

Hanauma Bay is actually formed from a volcanic cone, and after many years of wave erosion cutting through the Southeast wall of the cone it has given shape to the bay as we see it today.

In the Hawaiian language “Hanu” means bay, and “uma” means curved – So you can clearly see how Hanauma Bay got its name.

Hanauma Bay was voted the best beach in the United States in 2016, and there’s a reason this is the most popular snorkel spot on Oahu.

Not only are you guaranteed to see an amazing abundance of sea life here, but the fish that reside here are the friendliest and tamest that you will see anywhere.

The marine life are very used to human presence and won’t rush away when you get close to them. In fact, you will have no problems at all taking some amazing underwater selfies here!

Difficulty Level

Hanauma Bay is perfect for snorkelers of all ages and abilities.

The bay is well protected from the waves due to its surrounding walls, which means that the water inside the bay stays relatively calm.

It’s also pretty shallow so the conditions here are perfect for beginners and children.

Snorkeling Hanauma Bay

The education centre provides really useful information on which areas of the bay to explore, as well as what you might see while snorkeling Hanauma Bay.

There are many places to explore when you’re snorkeling in Hanauma Bay – For beginners we suggest sticking between the shore and the reef as the water is the calmest and shallowest in this area (about 1-2 meters).

It’s also recommended that beginners and people who aren’t the strongest swimmers avoid the two channels, as well as the central channel (as indicated above), as the currents are strongest here.

More experienced swimmers can swim further out and explore the deeper waters (around 6 meters deep), which is where you are more likely to see Green Turtles.

Where To Enter

You can enter the water from any part of the beach, however the area that is directly across from the opening of the bay can contain quite strong currents, as can the two channels that lead to the ocean. Try to avoid these areas if you are a beginner or not a strong swimmer.

Off Limits

  • Toilet Bowl – The water in the ‘Toilet Bowl’ rises and falls with the ocean’s tide, and resembles a toilet flushing (thus giving it it’s name). The water rises as it enters the bowl through an underground tunnel as the waves come crashing in, and then ‘flushes’ as the water is drained back out through the same tunnel. The Toilet Bowl was closed to the public in the early 2000’s due to safety concerns and visitors sustaining injuries on the sharp rocks.
  • Witches Brew – Another area to avoid is this small peninsula and cove to the right side of the bay where the waves can be very rough, and the currents strong.

Once these parking spaces become full security will turn away any additional vehicles from entering.

You’re welcome to bring your own food if you would prefer to have a picnic – Small coolers are allowed for those who wish to bring their own snacks and non alcoholic drinks.

Snorkel Equipment Rental

I always recommend purchasing and using your own snorkel gear.

There’s nothing quite like the quality, comfort and fit of your own gear (which hasn’t had thousands of other peoples mouths on it 🙂 )

If that hasn’t convinced you to invest in your own, then snorkel gear can be rented at the park, which also includes rental of prescription snorkel masks as well.

The cost of snorkel equipment rental is $20.00 per snorkel set.

Lockers can also be rented if you wish to store any valuables (keys, cellphones, handbags etc).

I would also say that underwater cameras are an absolute must as you’ll want to capture as much as you can of this underwater park!


Showers, restrooms and changing facilities are all located at the park.

The hill down towards the beach is pretty steep. It’s a nice walk down to the beach but after an action packed day of snorkeling the steep walk back up can be pretty tiring!

Conveniently, there’s a tram that runs up and down this hill all day. (The tram is free to use).


Lifeguards are present at Hanauma Bay.


There’s a reason Hanauma bay has previously been voted the best beach in the USA.

It’s a must visit location for snorkeling in Oahu, especially as it’s a great area for all ages and abilities.

It is really important that if you do plan on visiting that you arrive early!

The car park fills up extremely quickly and will stay full for most of the day. (In order to avoid disappointment I recommend arriving before 7am).

This way you’ll avoid most of the crowds and ensure getting a parking spot – early mornings also tend to provide the best conditions to explore this pristine marine ecosystem, so you’re more likely to spot an abundance of tropical fish at this time!
