What Is Hanauma Bay?
Just under 4 million years ago (who’s counting?), what’s known as the Waiʻanae volcano broke the ocean surface and created the current island of Oahu.
A mere 1.4 million years later the Koʻolau range of volcanoes followed suit to create the topography we see today. Luckily the volcanoes went dormant about 10,000 years ago.
The familiar landscapes, as seen on the TV series Lost, were created from those eruptions.
The Pacific tectonic plate that Hawaii rests on, was created from a ‘hot spot’ in geographical terms, which is where the magma from the earth’s core erupts on the seabed in the middle of a plate.
The hotspot is fixed, but the entire pacific plate is moving. The entire of Hawaii was formed when this hotspot caused eruptions on the seabed that broke the water surface.
What’s now known as the Hanauma Crater is said to have been created around 32,000 years ago in a series of violent rapid explosions. Over the following years, wave erosion has created a natural bay teeming with aquatic life.
Where Is Hanauma Bay?
Hanauma Bay is located on the Southeast tip of the island of Oahu, the third largest island in the Hawaiian group.

The easiest way to get to the Hanauma Bay nature park is via Honolulu. There are several ways.
Vehicle – Hanauma Bay does have a car park which costs $1 (300 spaces).
Waikiki shuttle – A shuttle leaves Waikiki and costs $25, which includes snorkel equipment rental.
Bus – The #22 beach bus leaves from Waikiki beach.
Best Time Of Year To Visit
For the very best chance of great weather, the best time to visit any of the Hawaiian islands is between March and September. During this period there’s less chance of rain and the highest temperatures.
The water temperature is at its best.
However, Hawaii has a perennial climate so the weather is good at all times of the year. Day temperatures will range between 73 – 86 degrees Fahrenheit (23 to 30 degrees Celsius).
From October to November there are fewer visitors which gives the islands a less touristy feel than normal. In the early few months of the year (Jan to Mar) the surfers arrive to capitalize on the oceans swells for surfing.

If You Go
Around 3000 visitors a day arrive at the national park so if you do go, it’s worth noting a few things.
Firstly, the marine life is given a break from human intrusion every Tuesday, so the beach is closed. It’s also closed on Christmas day and New Years day.
What to bring – Although there’s a lot to rent and buy while at Hanauma Bay remember to bring appropriate swimwear, towels, any day snacks you need, and a good sunscreen (wildlife safe). No alcohol consumption is allowed on the beach.
Don’t forget the entrance fee.
Consider reef shoes as there are plenty of places to cut your feet if you aren’t using fins. Additionally, people do report the sand can be a bit coarse.
Storage – At the beach level you can hire lockers if you feel the need, A small locker is around $12, and takes small items like wallets and phones. A larger locker that takes backpacks and handbags is available for $12.
Access – Completely free of charge, wheelchairs are available between 8am to 4pm.
Presentation – when you arrive you will be required to watch a small video about preserving the reef before you will be allowed onto the beach.
Shuttle services – A lot of the hotels will provide masks, snorkels, and fins for those going to the bay.
Lifeguards – At 6.15pm in the summer months, and 5.15pm in the winter months the lifeguards will start asking people to prepare for the closing of the bay, by requiring everyone to get out of the water.
Park gates – They close promptly at either 6pm, or 7pm depending upon the time of year.

Is Hanauma Bay Good For Snorkeling?
And here we come to one of the main reasons why snorkelers travel across the vast expanse of the Pacific ocean to visit Hanauma Bay Nature Preserve.
Along with the white sands, there is a very high fish population, with some 400 species present in the bay. Amongst the calm waters, you can appreciate just how unafraid of humans the fish have become.
They don’t dart off but will happily swim around you.
Note: Hanauma Bay Nature Preserve is exactly that, a nature preserve. As a visitor, you are asked to respect the wildlife and nature around you so it can be enjoyed by others in the future. By law, visitors are asked to not touch or feed marine life, as well as not to walk on the corals.
Throughout the entire length of the beach, you are allowed to snorkel. A barrier reef parallels the bay shoreline protecting the beach. If you are not a strong swimmer or are a beginner to snorkeling it’s best to stay beachside of the reef where the currents are manageable.
The depth of the inner part of the reef range from about 2 to 8 feet the length of the bay.
Marine Life
According to the nature preserve, there are 400 species of fish known to inhabit Hanauma Bay. It’s particularly known as a good spot for the green sea turtles.
The sheer amount of variety makes the bay a visual feast, and some of the very best snorkeling in the world because of it.
Common fish within the bay are;
- Green sea turtles
- Honu
- Parrotfish
- Surgeonfish
- Tangs
- Butterflyfish
- Trumpetfish
- Triggerfish
- Goatfish
- Moray eels
- Box Jellyfish
- Octopus
- Snapper
You’re probably likely to see a fair amount of sea urchins as well, although beware as those spines are painful.

Are There Dangers At Hanauma Bay?
It’s an idyllic spot for tourists, so it’s not surprising that the bay is continually voted one of the world’s best beaches for snorkeling. That beauty though, shouldn’t suppress a natural caution for respecting nature.
Danger can come in many forms, some are self inflicted, some from ignorance, and some from misfortune. The bay has been open for many years, and on any given year somewhere between 2 to 4 people lose their lives.
To put that in perspective, there are 3000 visitors per day or over a million per year. It perhaps gets a bad reputation based purely on the numbers of tourists arriving.
Around the preserve, there are warning signs about pretty much everything, from wet grass, low tree branches, and sloping terrain to more legitimate concerns like waves and rocks.
With the bay being closed off from the ocean in a natural crater enclosure can give a slightly false perspective to a tourist. It can give a sense of security when perhaps more caution is warranted.
There are 8 lifeguards around all the time, so you are safe from that point of view.
Nevertheless, the unforeseen dangers you perhaps need to worry about are as follows;
Breaking waves – If the sea is slamming waves into the rocks it’s advisable to stay away from the rocky ledges. They can be particularly dangerous during this time
The rocks are abrasive lava stone and crumble quickly. Additionally, they can be slippery so there’s a risk of slipping into the water.
Freak waves have washed people away in the past.
Sharp coral reef – Hanauma Bay has a coral reef in the shallow water near the beach. While providing shelter and attraction for sea life, the rocks are abrasive and sharp.
The lifeguards do have medical training for these types of injuries, but prevention is better.
Be careful in the swell of the waves as the coral reef is in shallow water. Ocean swells can slam a snorkeler down onto sharp coral.
High surf – during the summer months this isn’t quite the same danger but in the ‘non-tourist’ season large powerful waves can build up that provide the surfing waves.
Although the high surf affects all the islands, not just specifically the bay, these waves create strong currents making swimming more difficult. Also, these waves can push snorkelers onto rocks.
Currents and rip tides – If you’ve ever been caught, or seen a riptide effect you’ll already be aware, but these are powerful currents that aren’t always easily seen. These currents accompany a time of high surf, or with a rapid tide change.
Once caught in one, you won’t be able to swim against it. You will go where the current is taking you. If trapped in one, swim diagonally to it so you move into slower moving water.
Waving your hands above your head is the international distress signal.
If in doubt, ask the lifeguards where these currents are.

Are There Sharks At Hanauma Bay?
With the bay connected to the pacific ocean, a snorkeler might ask if they could see sharks on their visit. If there are any, what species, and are they dangerous?
Reef sharks have been known to visit the bay but many residents say they’ve never seen one so they aren’t common. It’s unlikely that you’ll see a shark on a Hanauma Bay trip.
Reef sharks are about 4 feet in length and aren’t man eating, and currently, there has never been a shark attack in the bay.
It’s a large bay, so the reef sharks may come in during the night if there are any about the area.
A shark isn’t something you need to worry about unduly if you are planning a snorkeling trip here. Of far greater concern are the currents.

Final Thoughts – Parting Waves
