Chain of Craters Road Chain of Craters Road is a scenic access road within Hawaii Volcanoes National Park on Hawaiʻi Island that links the summit area of Kīlauea to the coastal plain near Kealakekua Bay and offers views of active lava flows, volcanic craters, and native ecosystems. The route provides access to landmarks such as Puʻu ʻŌʻō, Halemaʻumaʻu, Mauna Loa, and coastal lava benches while serving as a corridor for scientific research, cultural interpretation, and public recreation in the context of ongoing eruptions. Managed by the National Park Service, the roadway has been repeatedly altered by eruptive events and inundations from repeated lava flows since the 20th century.

Overview

Chain of Craters Road traverses volcanic terrain that is central to the study of Kīlauea and Mauna Loa volcanism and to Native Hawaiian cultural sites associated with Pele (deity), ʻAumakua, and traditional land divisions such as ahupuaʻa. The road connects visitor facilities near Crater Rim Drive and Kīlauea Visitor Center with coastal features at Hōlei Sea Arch and lava fields adjacent to Pāhala and Keaʻau. It functions as an observation corridor for organizations including the United States Geological Survey and the Hawaiian Volcano Observatory, and it intersects interpretive stops that reference sites listed on inventories like the National Register of Historic Places.

History

The roadway originated from early 20th-century infrastructure projects influenced by territorial development policies and tourism promotion linked to figures such as Benjamin Dillingham and institutions like the Territory of Hawaii legislature. Construction phases during the 1920s and 1930s were affected by relief-era programs similar in spirit to those undertaken by the Civilian Conservation Corps in other national parks, while mid-century improvements corresponded with increased visitation following statehood and the growth of airlines such as Pan American World Airways. Major closures and reroutings have resulted from eruptions at Kīlauea Iki (1959), the Puu Oo eruption sequence (1983–2018), and summit events in 2018 that altered access to Halemaʻumaʻu and associated facilities. Park management decisions have involved coordination with agencies like the Federal Emergency Management Agency and cultural stakeholders including Office of Hawaiian Affairs representatives.

Route and Features

Beginning near the Kīlauea summit, the route descends through ecosystems containing plant communities studied by botanists from institutions such as Bishop Museum and University of Hawaiʻi at Mānoa. Along the alignment, motorists encounter named craters like Makahiki, geological exposures used in fieldwork by researchers affiliated with Smithsonian Institution programs and international collaborators from University of Tokyo and University of Cambridge. Interpretive pullouts describe archaeological features associated with voyaging narratives recorded by Captain James Cook and Hawaiian scholars such as David Malo. The road skirts landmarks including Devastation Trail, overlooks used by photographers who collaborate with publications like National Geographic, and access points to coastal lava flows that created new terrain mapped by agencies like NOAA and field teams from Scripps Institution of Oceanography.

Geological and Volcanic Significance

Chain of Craters Road lies within a dynamic volcanic setting governed by hotspot volcanism attributed to the Hawaiian hotspot and plate motion documented in studies by J. Tuzo Wilson and Don L. Anderson. The corridor provides direct views of pahoehoe and ʻaʻā lava morphologies described in classic volcanology texts by researchers such as Gordon Macdonald and Katherine Wohletz. The road has been essential for near-field monitoring campaigns conducted by USGS Hawaiian Volcano Observatory personnel and visiting volcanologists from institutions including Caltech, MIT, and University of Oxford. Eruptive episodes visible from the road have contributed to hazard mapping frameworks used by United States Geological Survey and emergency planners in County of Hawaii jurisdictions, informing mitigation strategies developed in cooperation with Hawaiʻi Department of Land and Natural Resources.

Visitor Access and Recreation

Visitors access the roadway from visitor centers operated by the National Park Service and can engage in activities promoted by partners such as Hawaii Tourism Authority and local outfitters based in Hilo and Kailua-Kona. Recreational opportunities include scenic driving, photography workshops run by organizations such as Sierra Club, guided hikes led by cultural practitioners including kumu hula and historians from Bernice Pauahi Bishop Museum, birdwatching lists compiled by the Hawaiʻi Audubon Society, and educational programs sponsored by Parks Canada-style institutes collaborating on comparative protected-area research. Seasonal considerations reflect volcanic activity warnings issued by the Aviation Weather Center and safety advisories coordinated with the Federal Aviation Administration for volcanic ash impacts on flights operated by carriers like Hawaiian Airlines.

Environmental Management and Conservation

Conservation along the corridor involves invasive species control initiatives similar to projects undertaken by The Nature Conservancy and native species restoration efforts that reference protocols from US Fish and Wildlife Service. Resource stewardship integrates cultural site protection guided by Office of Hawaiian Affairs consultation and archaeological standards aligned with the National Historic Preservation Act. Park staff collaborate with academic partners such as University of California, Berkeley and international research programs to monitor ecological succession on fresh lava, carbon sequestration studies linked to chronosequence research, and long-term biodiversity surveys tracked through databases like those curated by Global Biodiversity Information Facility. Adaptive management addresses climate concerns raised by panels including the Intergovernmental Panel on Climate Change and involves cross-jurisdictional coordination with agencies such as Hawaiʻi State Department of Health for visitor safety.
