Ala Moana Beach Park is a free public park on the island of Oahu, U.S. state of Hawaii, located between Waikiki and downtown Honolulu. This 100-acre (0.40 km²) park has a wide gold-sand beach that is over a half-mile (800 m) long. It is man-made and was created by the owner of the Dillingham Dredging Company, who was looking for a place to dispose of his dredged earth.
