Hanauma Bay (pronounced “ha-nowmah”, in Hawaiian) was once a spot reserved for Hawaiian royalty and favored for its great fishing. Hana in Hawaiian is “bay” and uma is “shelter”. The bay is both a nature preserve and Marine Life Conservation District (Hawaii’s first). Since 1967 Hanauma Bay has been one of the most often visited tourist attractions not just on the lovely Hawaiian Island of Oahu, but in the entire state of Hawaii. During some years the bay has welcomed over 3 million visitors from all parts of the earth to this scenic playground for children and adults alike.

Hanauma Bay Beginnings

The City and County of Honolulu bought the land containing and surrounding Hanauma Bay from the estate of Bernice Pauahi Bishop for the incredibly measly sum of $1. The area was opened to the public shortly after. Hanauma Bay began as a lovely fishing and picnic spot for Oahu residents willing to travel the dirt (lava) road to reach it. Later, in the 1930’s the road was paved and parking cleared.

During WWII Hanauma Bay was closed, afterward re-opening and in 1967 the bay was dedicated as a Protected Marine Area, by the Hawaii State division of Fish and Game. This had the effect of protecting everything in Hanauma Bay, from fish and sea life to the reef and, sand, and every living thing. White sand from Oahu’s north shore was shipped in to make it more suited for those that just wanted to enjoy the sunshine.

What is Hanauma Bay Today?

Hanauma is a large, incomplete circular bay which is a protected marine life conservation area protected by the state of Hawaii. The bay is shallow enough for tourists to enjoy wading, snorkeling and diving. The bay was created as the outside wall of a volcanic cone caved in, allowing the Pacific ocean to rush in. The sea floor is a mix of sand and numerous types of coral. It is possible to see over 450 types of fish here including the state fish – humuhumunukukuulualua, a reef triggerfish. The beach has sand and grass and is about a half mile long.

The mouth of the bay which is open to the Pacific ocean is small. This, and the large coral reef provide ample protection against large waves and large sea-animals like sharks. You won’t see sharks or dolphins in Hanauma Bay.

Geological History

Hanauma Bay crater was created by a violent volcanic eruption on Oahu tens of thousands of years ago. On the sea floor volcanic vents were created. These vents channeled liquid rock, magma, to the surface which reacted with the ocean water to form fine ash. Repeated explosions of magma formed volcanic cones of ash, which over time formed solid firma. Through the millenia the erosion produced by constant wave activity wore through the southeast wall of the Hanauma crater and allowing sea water to rush in. This formed the amazing “Hanauma Bay” we’re familiar with today.

The major reason people visit Hanauma Bay is the world-class snorkeling. It’s a once in a lifetime experience, the bay has a vast amount of open water you can explore – and both expert and novice snorkelers will find something to make the trip well worth it.


There is a large beach surrounding the bay and there is enough room for everyone, considering most will be splashing about in the ocean.

Hiking the Rim of Hanauma Bay

Most people never venture beyond the cool waters of the bay, but if you dared you would find a couple of hiking trails around the Hanauma Bay rim leading all the way to rocky lookouts overlooking the deeper Pacific ocean. It is well worth the time to explore these trails! You might even see a jeep or truck that has slid down the mountain and wedged itself into a gulley where it will no doubt rust away pound by pound. Give yourself an hour to explore the area on the trails on the right side of the top of the crater.

Toilet Bowl

Though it doesn’t sound very attractive, for years this was a major Oahu attraction before the state declared it too dangerous and had to close it off from the public. The toilet bowl is a hole in the lava that leads from the rocky cliff all the way to the ocean. When a wave rolls in it feeds the water up through the chute and fills this crevice


  • Arriving Late – if you arrive late you may not get a parking space at all. There is additional parking at the bottom of the hill you climb to reach Hanuama Bay, but it might be a hot climb. Arrive early!
  • Illegal Hanauma Bay Tours – Hawaii state has been cracking down on illegal tours bringing tourists to the bay. If you’re considering booking a tour of Hanauma call this Dept. of Parks & Recreation phone number for a list of companies approved to do tours 808-523-4525.
  • Lifeguard Flags – Lifeguards have flags and boards telling about up-to-the-minute cautions like jellyfish to be aware of. Check the lifeguard area first before you hit the water.
  • Theft – A fact of life in Hawaii is that theft is a problem at all Hawaii beaches and tourist attractions. Someone should (must) remain with valuables and take turns having fun in the water. If you’re coming to the bay alone you’ll want to have a waterproof sealable bag like they sell at dive shops – to protect your wallet, camera and things. You can then tow them around with you as you snorkel.
  • Feeding Fish – A friend of mine years ago held one pea in his hand and let the big reef fish eat it out of his fingers. That worked about twice. The third time the fish nipped his finger and he bled quite a bit! They have teeth similar to a parrot’s beak, but stronger and very sharp. Don’t hand feed the fish.
  • Touching Sea Creatures – Jellyfish, Portuguese Man-O-War, and sea anemones are dangerous creatures you may find as you snorkel Hanauma Bay. The lifeguards monitor the jellyfish and man-o-war closely, so you won’t be on your own there. A good rule of thumb is to avoid touching anything under the water, observe and take many pictures but refrain from touching.
  • Coral is Sharp – Be careful about stepping on coral, either with or without snorkeling fins because it is very rough and sharp at the same time – and can cut you easily. Be sure to warn your keiki (children).
  • Sea Conditions – The bay is secluded and naturally protected against most big waves. Pay attention to lifeguard signs.

Lifeguard Warnings

Pay attention when you go to the beach, to the lifeguard stands because they post important information about the place where you’ll be swimming or surfing. At Hanauma Bay they have these specific warning signs:

  • WARNING – SLIPPERY ROCKS – You could fall and be seriously injured. IF IN DOUBT, KEEP OFF.
  • WARNING – STRONG CURRENT – You could be swept away from shore, and could drown. IF IN DOUBT, DON’T GO OUT
  • WARNING – WAVES BREAK ON LEDGE – You could be swept off, injured, or drowned. IF IN DOUBT, KEEP OFF
  • WARNING – SHARP CORAL – May cause serious injury, avoid contact.
