Hanauma Bay on O‘ahu

Hanauma Bay (pronounced ha-now-mah) is a marine bay formed within a volcanic cone or crater and located along the southeast coast of the Island of O‘ahu (east of Honolulu) in the Hawaiian Islands. Hanauma is one of the most popular tourist destinations on the Island and has suffered from overuse.

Hanauma Bay is the very best spot on Oahu for snorkeling, and caters to everyone from beginners to the most experienced snorkelers. On most days, the bay offers to swimmers a picturesque view of the oceanlife.

Visitors are required by law to refrain from mistreating the animals or from touching, walking or otherwise having contact with the coral, which appear like very large rocks sitting on the ocean floor. However, even if this law were not in place, it is highly recommended not to walk on the coral as it can and will damage the skin. It is particularly unwise to neglect wounds sustained from swimming in areas like these, as bacteria may grow in the gash, causing more complications and problems.

Admission is free to the "Kama'aina," or those who reside locally upon showing identification. All others are asked to pay a small fee to enter. Private companies also cater to the public with tram rides and food services, as well as supplies for snorkeling.
