Kewalo Basin is a commercial boat harbor that serves as home to some of Honolulu's commercial fishing fleet, and charter and excursion vessels that serve the Hawaii tourist market. Pre-European contact, the area was historically used for human sacrifice. On the ocean side of the harbor is a small beach park on the Honolulu waterfront, located adjacent to the larger Ala Moana Beach Park. This park is good for swimming, picnicking and sightseeing. It can be accessed from the corners of Ala Moana Boulevard and Ward Avenue.
