Hanauma Bay is a world-renowned marine sanctuary and beach located on the eastern coast of Oahu, Hawaii, about 10 miles east of Waikiki. The bay is a popular destination for tourists and locals alike, known for its crystal clear waters and abundant marine life.

Hanauma Bay was formed within a volcanic cone and is now home to over 400 species of fish and other marine life, including green sea turtles, reef sharks, and rays. The bay is protected by a barrier reef that helps to maintain calm waters, making it an ideal location for swimming, snorkeling, and diving.

In order to preserve the delicate ecosystem of the bay, visitors are required to watch a short educational video on marine life conservation and preservation before entering the park. Snorkeling gear is available for rent, and lifeguards are stationed throughout the park to ensure the safety of visitors.

Hanauma Bay is open every day except for Tuesdays, Christmas Day, and New Year’s Day. It is a popular destination, and visitors are encouraged to arrive early in the morning to avoid crowds and to ensure they have enough time to explore the bay.
