Koko Head is the headland that defines the eastern side of Maunalua Bay along the southeastern side of the Island of Oahu in Hawaii. On its western slope is the community of Portlock, a part of Hawaii Kai. Koko Head is an ancient tuff cone that is somewhat dwarfed by its neighboring tuff cone, Koko Crater, with its peak, Kohelepelepe, rising to 1208 ft or 368 m. Koko Head itself has three significant depressions or old vents, the largest of which forms the well-known Hanauma Bay. Koko Head's last eruption was 30,000–35,000 years ago and it is part of the Honolulu Volcanics. This eastern end of Oahu is quite scenic and most of the area is part of Koko Head Regional Park, administered by the City & County of Honolulu. The following features and natural areas are found between Koko Head and the eastern end of the island at Makapuu:
Koko Crater is a large tuff cone that visually dominates the area. Within the crater are horse stables and the Koko Crater Botanical Garden specializing in cacti and succulents.
Lānai Lookout is a scenic lookout that features a very distant view of the Island of Lānai to the southeast of Oahu. Molokai, directly across the Ka'iwi Channel, is closer and nearly always visible during the day; Lānai is visible only under good atmospheric conditions, although if visible from anywhere on Oahu, it will be visible from this pull-out/parking area. The cremated ashes of Barack Obama'smother and maternal grandmother were scattered here in 1995 and 2008.
Sandy Beach is a popular beach for surfing and a park popular for kite flying because trade winds are strong and steady most days. Sea conditions off the beach tend to be rough most of the time and the bottom drops away relatively quickly, so this is not a beach for relaxed swimming, but very popular for more extreme water sports and watchers.
