Hanauma (pronounced "ha-na-OO-mah", in Hawaiian) is a marine embayment formed within a volcanic cone and located along the southeast coast of the Island of Oʻahu (just east of Honolulu) in the Hawaiian Islands.[1] Hana means 'bay' and uma means 'curve,' rendering "Curved Bay." Though some call it "Hanauma Bay," this is a tautology: Hawaiians simply call this feature "Hanauma". Hanauma is one of the most popular tourist destinations on the Island and has suffered somewhat from overuse (at one time accommodating over three million visitors per year). In the 1950s, dynamite was used to clear portions of the reef to make room for telephone cables to be brought in underwater. Some of this can still be seen today, and this section of the bay is called "Cable Channel."
