Spouting Horn
Koloa, HI
A lava-tube blowhole on the south shore that shoots sea spray into the air with a loud hiss, strongest at high tide.
Spouting Horn is a blowhole on the south coast of the island of Kauaʻi in Hawaiʻi, in the Koloa district and one stop on the roughly 10-mile Koloa Heritage Trail. Surf forces water through openings in the lava rock of the coast, so it shoots upward as a fountain with a hissing sound.
According to Lonely Planet there are two blowholes in a lava-rock reef, usually sending up spouts under 30 feet (about 9 m) that last only seconds; in big surf they can roughly double. Wikipedia mentions spray up to about 50 feet (15 m). There is also a legend about its origin: a giant lizard, a moʻo, is said to be stuck in the lava tube, and its roar can be heard with every spout.
The path from the parking lot to the viewpoint is lined with souvenir stalls, which Lonely Planet describes rather unkindly. Tour buses stop here often, so expect crowds.
