Twenty-mile long Chain of Craters Road will now lead you downward toward the sea past multiple craters along the East Rift Zone. Highlights include viewing the park's coastline along with endangered nene birds... at the Hilina Pali Lookout, exploring the collapsed crater ominously named Devil's Throat, encountering magnificent vistas, and walking the Pu'u Loa Petroglyph Trail (home to the largest collection of petroglyphs in Hawaii).
