Chain of Craters Road runs from the Devastation Trailhead down to the coast in Hawaiʻi Volcanoes National Park. It is paved and needs no four-wheel drive, though vehicles over the park size limit are not allowed. Lava from the Puʻuʻōʻō eruption flowed over the road again and again, and the park's coastal region was once home to a number of villages, whose trails, house sites, heiau, petroglyphs and farm sites tell of its long use. Along the road are the Maunaulu parking area and the Puʻuloa petroglyph trailhead, where a hike across a lava field leads to the petroglyphs. There is no food, water or fuel anywhere on the road, so fill up and pack water before you start down. Phone service is limited; the emergency phone is at the Puʻuloa petroglyph trailhead. Vault toilets are at the Maunaulu parking area and at the end of the road, where the road closes to vehicles at a turnaround. Hōlei Sea Arch, near the end of the road, has collapsed into the ocean. The coastal cliffs are unstable and can collapse without warning, so stay out of closed areas and back from the edge. Watch for nēnē on the road, since cars are the leading cause of adult nēnē deaths in the park, and never feed them.
Paved, no four-wheel drive needed; oversize vehicles not allowed; no food, water or fuel along the road.
