One of the few black sand beaches in Hawaii, Oneuli (also called Naupaka) is located on Maui's southern side off Makena Alanui Road near the Grand Wailea Resort. It's actually part of Makena State Park by the Pu'u Ola'i cinder cone on the Wailea side. The cinder cone is a geological landmark which can be seen from several points along the coast. Properly named, Oneuli means "dark sands" in Hawaiian. The sand here is made up of ground black lava, unlike most other black sand beaches made from ground shells and corals.
