Holei Sea Arch, Iconic Hawaii Rock Formation, Collapses
The Holei Sea Arch, a 90-foot natural rock formation in Hawaii Volcanoes National Park on Hawaii Island, has collapsed into the Pacific Ocean.
Phoenix, AZ, October 2, 2026 — The Holei Sea Arch, a prominent natural landmark located in Hawaii Volcanoes National Park on Hawaii Island, has reportedly collapsed. The rock formation, estimated to be 90 feet in height, is now submerged in the Pacific Ocean.

The park, located on the southeastern side of the Island of Hawaii, is a popular destination for visitors seeking to experience the raw power and beauty of volcanic activity and its impact on the environment.
The specific timing and cause of the collapse, beyond natural erosion, were not detailed in the available information. Information regarding any impact on park access or visitor safety protocols following the event was not provided. The formation’s disappearance represents a natural alteration of the island’s coastal geography.
