Honolulu Caves, Cliffs & Canyons
Kaneana Cave can be found at the base of a 200 ft. outcropping of rock along Farrington Highway. Approximately 100 yards deep, this cave is said to be the former home of Nanue, the shark man. It should be noted that this site is not marked by any signs and has not been maintained. The cave can be seen when going South on Farrington Highway from Kaena Point. Parking is available across the street from the cave entrance.
Koko Head is a 640 ft. ancient volcanic hill that sits on the east side of Maunalua Bay. The cliff features three vents, one of which forms Hanauma Bay. Koko Head is surrounded by the community of Portlock, the Lānaʻi Lookout, Hālona Blowhole and the popular Sandy Beach.
