Spouting Horn

Spouting Horn is located in the Koloa district on the southern coast of Kauai. This area of Kauai is known for its crashing waves (nearby Poipu translates to "crashing"). These waves erode lava rocks on the coastline which can create narrow openings, as is the case with Spouting Horn. With every wave, water shoots upward when it is forced through an opening and creates a sound suggestive of hissing. The spray can shoot as high as 50 feet in the air.^[2] Spouting Horn is one of the most photographed locations on the island of Kauai. The original Hawaiian name was puhi, meaning blowhole.^[3] The Spouting Horn is a part of the Koloa Heritage Trail, a 10 mile trail in the Koloa district.
