Mokoli?i, also known as Chinaman’s Hat, is a basalt islet in K?ne’ohe Bay, Hawaii. Mokoli?i is part of Kualoa Regional Park and located 1?3 mile (0.54 km) offshore of Kualoa Point, Oahu. The 12.5-acre (5.1 ha) islet was at one time part of a basaltic ridge on Oahu before marine erosion separated it.
