Hanauma Bay is one of the most popular Oahu attractions and snorkeling activates on the island. There is a nice expansive beach to relax on, but it's really all about the marine life nature preserve sanctuary and the amazing snorkeling experience that this special place provides! With over 450 different Hawaiian fish species lurking about the shallow coral reefs, it is easy to see why this Oahu Beach is so famous!
Over a thousand years ago, a violent eruption blew out one side of the crater, creating the crescent
moon-shaped beach that exists today.
The lava rock tubes created a perfectly protected home for hundreds of tropical fish and beautiful marine life that live there today.
As a kid, I loved visiting and snorkeling this amazing natural marine preserve to explore the reef’s protected caves & tunnels, and vast display of colorful Hawaiian fish – it’s like jumping into a giant fish bowl...!
Discover the Keyhole lagoon area located on the left hand side of the bay. You should notice it as you descend down the hillside towards the beach. It has a distinct key-head shaped sandy area in the ocean that is surrounded by an expansive reef wall to explore.
Back in the day, visitors would even feed the fish. But you can imagine how cloudy the waters became when each visitor had a bag of bread or part of their lunch in the ocean, trying to attract a feeding frenzy around them...not to mention that human food is not necessarily the best fish food.
As this Oahu beach started to become more polluted and neglected, state park officials stepped in and made necessary changes to the Marine Life Preserve at Hanauma Bay. The marine park now looks much better with the provided care.
Today, you obviously are not allowed to feed the fish, and they also now control the amount of visitors allowed in park at one time. Only 1400 visitors are allowed into this snorkeling haven per day, so it is well-advised to arrive early.
1400 might seem like a lot, but they used to easily get over 10,000 visitors each day. The marine park also takes a break and closes to the public on Mondays and Tuesdays when nobody is allowed in. Even the fish and the coral reefs need a break from their adoring fans.
To better protect the Hanauma Bay fish and coral reefs, they have also created a mandatory 9 minute education program before heading down to the beach. It highlights the importance to not walk on the reef, keeping your distance and not harassing the fish, and water safety.
This constitutes watching a quick 9 minute video on how to better protect what you are about to see.
While this might look like beautiful artwork, it actually is a wreath creation from just a single month collection of trash and belongings left behind at this beach. Make sure to do your part and leave with everything you bring in...
Hanauma Bay has a nice sandy beach that stretches for almost a third of a mile or about 2000 feet long. It's a playground haven for kids, but you must keep an eye on them if they enter the water.
And while most visitors will set up camp right after they step onto the beach near the key Hole Lagoon. We recommend walking down a bit to the right near the Triangle Lagoon area, where you can have enjoy a little more space away from the crowds.
Part of what makes Hanauma Bay so
special, is that it lies
at the bottom of a volcanic crater.
Here's a view of the bay from the top... below provides an ideal setting for snorkeling in Oahu.

Set yourself up for a half day of discovery and adventure along the southern tip of Oahu, hiking up to an amazing viewing platform with views of the Windward side and lighthouse, and also to the top of Diamond Head.

Take advantage of the free beach shuttle ride when you
the parking lot located up top.
It is an easy 25 minute drive or 45 minute bus ride to and from Waikiki.
The Waikiki Trolley visits many Honolulu Attractions including the Halona Blow hole near Hanauma Bay. It is an easy, popular, and convenient way to get to popular Oahu attractions.
There are 4 different routes to explore including: Scenic Tour, Historic Tour, Shopping Tour, and the Island Tour. The Blue Line will take you past Diamond Head and out to the Halona Blowhole. Tickets start around $15 for a child day pass, and go up to $45 - $75 for an Adult 7 day pass.
From Waikiki, take the H-1 Kalanianaoli Highway South. The H-1 turns into Hwy 72, but still remains the Kalanianiaoli Hwy along the coast. Follow this coastal freeway through the residences, past Hawaii Kai, and up a ridge until you reach Hanauma Bay Road, where you will turn into the parking lot.
Take the 22 Oahu Bus from Kalakaua Ave in Waikiki straight to Hanauma Bay. Depending on traffic, it should only take about a half hour to get there.
If you continue on from the 72 Kalanianaoli Hwy after snorkeling in Hanauma Bay, there is a fun spouting blowhole that is just down the road.
After driving around the single cliff side lane, you will see a small turnout with parking, right before you head on down to Sandy Beach Park.
The waves are the key for the Halona Blowhole magic to happen. Don’t expect much if the waves are small and calm. But when the seas are rough and the waves are pounding into the rocky coast, you can bet that the Halona Blowhole will be spouting ocean spays high in the air to give you a magnificent show.
Also discover the Eternity Beach that is located in this same area...
Go from the calm Hanauma Bay to the pounding shorebreaks of Sandy Beach Park. This Oahu Beach is an ocean playground for the locals to relax, body surf, and body board.
Located just 5 minutes away, as you continue driving on the H-1 around the bending lava rock cliffs, you will see a long strip of sandy beach.
If you are feeling adventurous and would like to see one of my favorite Oahu Beaches, and part of the beautiful Windward coast, then continue on the Kalanianaoli Hwy for another 10 minutes.
After you climb the Makapu’u mountainside
and start your decent down towards the beach, pull over to the
the road where you can capture some amazing views of Makapu’u
and the beginning of the pristine Windward Coast.
Climb a little higher from the Makapu'u Point Lookout, and the view becomes even more spectacular at the top, and at the Makapuu Lighthouse! It's a nice 1 mile hike up a paved path.
You will want to start this Oahu hike early as it tends to warm up quickly on the south side of the island.
Looking to conquer the big hill? Climb the Koko Crater Trail and the hill just might conquer you!
The Koko Head Steps can be a lot of fun, but it is quite challenging at the same time, as you’ll be climbing 1,050 long steps up to the top!
The “steps” are actually
old military railroad ties for a train that once ran supplies to
top ridge. Make it to the top of this Oahu hiking trail, and
will be rewarded with incredible panoramic views of the surrounding
area, including Hanauma
Bay, the Koko Marina, and Sandy
