Spouting Horn
A natural blowhole on Kauai south shore that shoots seawater through a lava tube creating a geyser-like eruption and an eerie moaning sound. Kids are mesmerized by the unpredictable eruptions that can shoot 50 feet into the air. The viewing area is safe and paved with a railing. The sound the blowhole makes as air is forced through the tube is haunting and tied to a Hawaiian legend about a giant lizard trapped in the rock. The whole visit takes 15 to 20 minutes and pairs well with a stop at nearby Allerton Garden.
