Hawaii · United States
Molten lava tubes from volcanic eruptions that occurred from Oahu’s Koko Head crater formed the natural occurrence known as the Halona Blowhole. This lava tube extends into the ocean with a very narrow opening at the top, and when the surf is just right, water pressure builds up within the lava tube and erupts through the narrow opening creating a special Hawaiian Geyser for your viewing pleasure.
