About This Beach

Hanauma Bay Nature Preserve, located on the southeast coast of Oʻahu, Hawaii, is one of the most famous and breathtaking snorkeling destinations in the world. Formed within a volcanic tuff ring, the bay features crystal-clear waters, vibrant coral reefs, and over 400 species of tropical fish, many of which are found only in Hawaii.

Unlike typical tourist beaches, Hanauma Bay is a protected marine conservation area, designed to preserve its delicate ecosystem while allowing visitors to experience Hawaii’s underwater beauty. It’s a must-visit for families, couples, and anyone looking to connect with nature.

  • Marine Conservation: Once overrun with visitors, Hanauma Bay was designated a protected nature preserve in 1967, ensuring its long-term preservation.
