Hanauma Bay

Every year, over a million visitors have the chance to swim with the fishes in a stunning marine ecosystem nestled on the southeast coast of Oahu, just 10 miles east of Waikiki. Hanauma Bay, which means "curved bay," is a former volcanic crater that was designated as a protected marine life conservation area in 1967. It's since transformed into an underwater paradise for snorkelers, swimmers, and anyone eager to encounter over 400 species of Hawaiian fish. Look out for Hawaii's state fish, the humuhumunukunukuapua‘a, as well as turtles and a host of other marine life.

Hanauma Bay Nature Preserve welcomes visitors all year, except on Tuesdays, Christmas, and New Year’s Day. To make the most of your visit, try to arrive early to beat the crowds or opt for a visit later in the afternoon when it starts to quiet down. During the summer months, the park opens its gates at 6 am and closes at 7 pm, while in the winter, it wraps up at 6 pm.

A fun fact to keep in mind: Hanauma Bay is not just a haven for marine enthusiasts but also for those interested in geology. The bay's unique shape and formation are a testament to the island's volcanic history, offering a fascinating glimpse into the natural forces that have shaped this beautiful part of Hawaii.
