Hanauma Bay

Hanauma (/ˌhɑːnəˈuːmə/; Hawaiian: [həˈnɔumə]) is a marine embayment formed within a tuff ring and located along the southeast coast of the Island of Oʻahu in the Hawaii Kai neighborhood of East Honolulu, in the Hawaiian Islands.

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 1956, dynamite was used to clear portions of the reef to make room for telephone cables linking Hawaii to the west coast of the US.
