Spouting Horn Blowhole

On the South Shore you can find the Spouting Horn. There's a small beach park with a great lookout where you can watch a blowhole spout a plume of thundering water into the air. This waterspout occurs whenever the waves are forced under the rocky shelf and up through a lava tube. The water sometimes hisses and roars. If the light is right, you may be able to catch a rainbow in the sea spray.

Access to Spouting Horn Park is easy with plenty of parking and the view from the lookout is especially good at sunset. There's also a trail down onto the lava shelf which is worth exploring. There are some great views of the rugged Poipu coastline and bay from there.
