Spouting Horn Park is a coastal viewpoint on Kauaʻi’s South Shore, near Poipu, where waves push through a lava opening and send water into the air with a loud rush. The main spout can rise around 50 feet, with smaller blowholes nearby. From the viewing area, you can watch the surf and look for sea turtles near the rocks. Parking, public restrooms and picnic tables make this an easy short stop; stay behind the railing and away from the shoreline, where waves and wet rocks are dangerous.
How the blowhole works
Spouting Horn, known as puhi in Hawaiian, formed as waves wore away softer rock along the shore beneath a harder top layer. The water enters a coastal opening and is forced through a narrow outlet, shooting upward in a plume and making a loud blowing sound. The height depends on the surf, and the spout can reach around 50 feet.
A Hawaiian legend tells of a giant moʻo, or lizard, trapped inside the blowhole. The story is part of the place’s cultural context; the natural formation itself comes from wave erosion.
Viewing the shoreline safely
The viewpoint lets you watch the blowhole from above, without hiking down to the water. The rocky coast is exposed to powerful waves, and the wet surfaces can be slippery. Keep behind the railing and do not approach the openings or shoreline, even when the surf looks calm.
The main spout is the central draw, but smaller openings can also send up water. Sea turtles have been seen swimming near the rocks. Look out over the water from the designated viewing area rather than walking closer to get a better view.
Planning a short stop
Spouting Horn Park is on Lawai Road near Poipu, on Kauaʻi’s South Shore. Parking is close to the viewing area, and public restrooms and picnic tables are available. The stop works as a brief break while exploring the coast, or as a place to pause for ocean views at sunset.
For a more active spout, plan around high tide and larger waves; the display varies with the surf. Early morning can make parking and reaching the viewpoint easier. The area can also draw tour buses, so allow for other people at the lookout.
