This rock formation was born from [[Erosion#Coastal erosion|marine erosion]], in which the waves of the [[Pacific Ocean]] create this [[natural bridge]] of lava cliffs. The arch is made of [[basalt]].<ref>{{Cite web|url=http://epod.usra.edu/blog/2006/05/holei-sea-arch.html|title=Holei Sea Arch - EPOD - a service of USRA|website=epod.usra.edu|access-date=2018-06-05}}</ref> It takes its name from the Hōlei Pali, the [[escarpment]] located up on the slopes of the volcano.
Located in the [[Ka'ū|Ka'ū District]] of [[Hawaii County]] and in the [[Hawaii Volcanoes National Park]], it is at the end of the [[Chain of Craters Road]], cut short by the lava flows emitted by [[Puʻu ʻŌʻō|Puu Oo Crater]] since 1990. It thus constitutes a tourist attraction of the national park. A total of 4 people in the past decade have fallen off to their death.
==Transportation== It is accessible by car via the Chain of Craters Road from [[Halemaʻumaʻu]], the main Kīlauea [[caldera]].<ref>{{Cite web|url=https://www.nps.gov/havo/planyourvisit/ccr_holei.htm|archive-url=https://web.archive.org/web/20150328200456/http://www.nps.gov/havo/planyourvisit/ccr_holei.htm|url-status=dead|archive-date=March 28, 2015|title=Hōlei Sea Arch - Hawai'i Volcanoes National Park (U.S. National Park Service)|website=www.nps.gov|language=en|access-date=2018-06-05}}</ref>
