Hanauma Bay, Oahu

Ever fancied swimming amidst some of the world's rarest marine wildlife? It can't get much better than at Hanauma Bay, located on Oahu's southeastern shore near Hawaii Kai. Named America's best beach in 2016 by coastal scientist Dr. Stephen Leatherman, aka Dr. Beach, Hanauma Bay is a longtime favorite among snorkelers and marine enthusiasts. It is home to over 450 kinds of tropical fish, many of which can only be found in Hawaii. Here you can observe marine life up close, including the humuhumunukunukuapua‘a, the Hawaiian state fish. Feeding, chasing or touching the fish and turtles is not allowed, but you can swim alongside them and take pictures. You can rent snorkeling gear from the nearby shops, and lifeguards are more than willing to assist beginners.

Although often called a beach park, Hanauma Bay is actually a nature preserve established to protect the delicate ecosystems in the bay. Visitors have to watch a short educational video about the bay's history and wildlife before entering the beach. A steep, but paved road leads down to it. If you don't feel like walking or have a physical disability, there's a shuttle bus that takes people to the beach.

If you forgot to bring your own food, there's a concession stand at the entrance of the bay. There's also a gift shop and shower facilities. Non-residents of the state of Hawaii have to pay an admission fee of $25 to enter Hanauma Bay. This fee is waived for Hawaii residents, active military and children under 13. There is a parking fee ($3 per vehicle for non-residents and $1 per vehicle for Hawaii residents). The beach opens at 6:45 a.m. every day, except Mondays and Tuesdays when it is closed. Only a limited number of walk-in or drive-in tickets without an online reservation is available. Hawaii residents may access Hanauma Bay without a reservation during all open hours. If you are planning to visit Hanauma Bay, it is recommended to reserve your tickets in advance.

Special Note:

Hanauma Bay is the top site on Oahu for drownings. Although the bay is protected by a reef and the nearshore waters are usually calm, Hanauma Bay is considered one of the deadliest beaches in Hawaii. According to the State Department of Health, 32 people died here between 2009 and 2018. Keep this in mind when planning a trip to Hanauma Bay. Always go snorkeling together with a buddy and stay together at all times. If you are not an experienced open ocean swimmer, stay close to the shore and don't swim out of the channel at Hanauma Bay (the channel that leads into deeper waters behind the reef).

Frequently Asked Questions

What does Hanauma mean?

Hanauma is commonly connected with the bay's curved shape. Another interpretation links the name to uma, a traditional hand-wrestling game once associated with the area.

Why does Hanauma Bay require an education video?

The video explains how to move through the reef area without stepping on coral, feeding fish or crowding marine life. That conservation focus is part of what makes Hanauma different from a regular beach park.

How was Hanauma Bay formed?

The bay is a flooded volcanic crater created by explosive eruptions along Oahu's southeast coast. The curved shape, high crater walls and reef inside the bay all come from that volcanic history.

What fish might you see at Hanauma Bay?

Common reef sightings can include parrotfish, butterflyfish, triggerfish, tangs and other colorful fish. Watch quietly, leave plenty of space and never feed them.

Why is Hanauma Bay closed two days a week?

The Monday and Tuesday closure gives the preserve regular time without daily visitor pressure. It is one reason the bay now has a slower, more managed rhythm than it did decades ago.
