Kii pohaku (petroglyphs, literally “rock pictures”) may be the closest thing to a written language that Hawaiians used, and some are thought to be astronomical symbols, road signs or markers of historic events. Join expert Kalei’ula Kaneau for a moderate 1-hour walk back through Hawaii’s fascinating history, and see for yourself. Sunblock, hat and covered walking shoes recommended as the trail is uneven and rough in places.
