Hawaii’s famous Hōlei Sea Arch, a 90‑foot lava structure that stood for 550 years, collapsed into the Pacific between September 23 and 27. The National Park Service had warned of its eventual crumble, and the latest tropical storm likely accelerated the process. The loss of this striking landmark reminds visitors that nature is in constant motion. Social media buzzed with nostalgic comments from those who admired the arch.

When giants fall.

Hawaii’s iconic Hōlei Sea Arch – a 90‑foot tall lava rock that had stood for about 550 years – collapsed into the Pacific Ocean between September 23 and 27.

The arch was still visible on September 23, but by the end of the month it was gone. The National Park Service says the cliff that supports the arch had been showing signs of instability for years. A tropical storm called Nolo that hit just before the collapse likely broke a chunk of rock from its base, sealing the arch’s fate.

The park has moved visitors away from the original cliff face since new cracks appeared in 2020, and a safer viewing area was opened. First‑hand accounts of the collapse flooded social media, with many sharing photos and memories of the arch.

In one Facebook comment a visitor wrote, “Nothing and no one is here forever.” The National Park Service added that while the sea arch has a limited lifespan, future cliffs will keep moving and new limestone features may rise.

So while the Hōlei Sea Arch is gone, the Big Island’s coast is still an ever‑changing masterpiece of nature.
