Keanakakoi Crater Rim Road

Keanakakoi Crater Rim Road traces the edge of Kilauea’s caldera to reach historic quarry sites where Hawaiian craftsmen once harvested volcanic glass for adzes, spear points, and cutting tools. The route splits off from Crater Rim Drive before the 2018 eruption damage, winding through native ohia forests and across older lava flows to reach the Keanakakoi quarry complex. These pits represent thousands of years of indigenous industry, with stone tool fragments still visible in the excavated walls and surrounding debris fields.

Moderate difficulty with loose volcanic rock requiring careful tire placement and momentum management. Stock 4WD handles most sections, but sharp obsidian fragments can puncture tires so bring a full-size spare and patch kit. Road access changes frequently due to ongoing volcanic activity and National Park Service closures. Check with Hawaii Volcanoes National Park rangers before attempting. Best during dry months when visibility is clear and road conditions are most stable. No camping allowed, but this connects to longer backcountry routes for those with proper permits.
