1. About the Hanauma Bay

Hanauma Bay is located on the southeast coast of the island of Oahu in the Hawaii Kai neighborhood, present in the county of Honolulu on the Hawaiian island. 

The prefix Hana in the name refers to ‘bay’ in the Hawaiian language, and Uma means curve. Therefore, the possible translation of the name could be a curved bay.

Hanauma is a nature preserve and a marine life conservation district; therefore, the name Hanauma Bay Beach changed over time and was replaced by the name Hanauma Bay Nature Preserve.

A marine education center was opened to educate people about the rich marine ecosystem of the bay, which was formed when strong ocean currents had broken the seaward side of a volcanic crater and flooded the crater floor.

As the years passed by, with the strong erosive forces of the oceanic currents, the seaward cater wall entirely collapsed, and a white sand beach and a huge reef formed instead.

Also, did you know the oldest coral found in the bay is 7000 years old? The coral reef on the beach is extended 300 meters offshore to prevent the big oceanic waves from reaching the beach.

2. What Can You Do in Hanauma Bay? 

The grand and exquisite Hanauma Bay is famous for its snorkeling experience, accompanied by crystal clear water and rich marine life. People come far and wide to experience this bay’s spectacular marine life.

The experience of swimming underwater, according to the tourists, is like swimming in an aquarium. It is filled with colorful and rare fishes and exquisite coral reefs.

When the sunlight hits the coral reefs, the reefs then shine in all colors ranging from pink to yellow and black.

The bay is teeming with flora and fauna of all kinds. Did you know that the bay is home to more than 450 species of tropical fish?

You can witness fishes like Reef triggerfish, butterflyfish, squirrelfish, and many more. Also, do you know the bay is famous for green sea turtles?

During your snorkeling experience, you will observe the fish swimming up to the reef, and since they are not afraid of human interaction, you can also find some swimming directly up to you.

One of the most thrilling experiences that can be part of your trip to Hanauma Bay is night diving in the bay.

Rent a waterproof flashlight, dive underwater, and enjoy the breathtaking sceneries that the ocean provides.

It is said that different fishes come out at night, and if you are lucky enough, you can also see an octopus swimming beside you.

3. Tips and Measures to Keep in Mind

As mentioned, being one of the most popular spots for snorkeling, the island has suffered tremendous overuse from humans over the years. And these have led to the hampering of the marine ecosystem.

So, to restore the fragile ecosystem, the authorities decided to enforce a strict set of rules and regulations. These preventive measures should be considered, especially if you plan a trip to Hanauma Bay.

These tips apply for both snorkeling and in general.

  1. Since Hanauma Bay is a popular place for snorkeling, the standard entrance fee is quite low, and so is the parking fee. So, make sure if someone is trying to charge a higher price for your experience at the bay, make sure to report that to the authorities. 
  2. The parking fee is low, but the parking lot gets filled up quickly, so make sure you reach the place early. 
  3. If you are a native citizen of Oahu and have a valid identity card stating you are a citizen of Hawaii, there will be an entry fee charge. The same applies to people who have an active military card in Hawaii. 
  4. Since 1990, the authorities have banned feeding the fish. So keep in mind not to offer any food to the fish as it can lead to water pollution and potentially change the fish’s behavior.
  5. Watch a short video shown before entering the bay so you can have prior knowledge about the ecosystem. 
  6. Smoking, alcohol consumption, and fishing are strictly prohibited.

Hanauma Bay is a place where people come to enjoy themselves in the water and have fun.

Several drowning cases are reported yearly in the bay, so be safe. However, with that being said, be sure to follow all the guidelines and safety tips provided by the authorities.

There have been many instances where inexperienced swimmers have underestimated ocean currents’ power and have succumbed to their deaths.

Stay close to the shore if you are a novice at snorkeling or if it is your first time in the bay. Also, do not forget to go snorkeling with a partner or alone, but never alone.

Another thing that you should be cautious of in the bay is the coral reefs. The coral reefs are sharp and can cause severe infections if they come in contact with humans.

If you get cut by the reef, wash the infected area with mild soap and fresh water and immediately apply first aid to the affected area.

Make sure no pieces of coral or microbes are present in the wound. Also, apply an antibiotic ointment for better protection.

The park was closed due to the Covid pandemic. After that, certain rules were tweaked for safety reasons when it opened. These are:

  1. There will be only limited visitors a day. 
  2. The bay will be closed two days a week.
  3. Maintaining social distancing is a must. 
  4. Fees have slightly gone up, and so have the parking regulations.
  5. Commercial tours on the bay have stopped. 
  6. Gift shops, good joints, and education centers are completely closed. Visitors need to bring their food and snorkeling gear.
