Spouting Horn is one of Kauai’s most iconic natural wonders, located on the sunny south shore in Poipu. This dramatic blowhole shoots seawater up to 50 feet into the air through a natural lava tube, creating a spectacular show with each crashing wave. The sound of the water rushing through the narrow opening creates a hissing or roaring noise, adding to the legend that a giant lizard once guarded this coast and was trapped beneath the lava rock.
Easily accessible with a scenic viewpoint and ample parking, Spouting Horn is a favorite stop for visitors of all ages. The viewing area also features local artisan stands, restrooms, and panoramic views of the rugged coastline. It’s especially striking at sunset, when the golden light enhances the mist and movement of the spray.
Don’t miss: Nearby attractions like the National Tropical Botanical Garden and Poipu Beach make this a perfect addition to your south shore itinerary.
