Blowhole

A natural blowhole on the rugged northwest coast of Maui that shoots ocean water up to 100 feet in the air when the surf is up. The short hike down from the road (about 0.6 miles) crosses rocky lava terrain to a dramatic coastline. Kids are thrilled by the eruptions of water from the blowhole. The surrounding lava formations and tide pools are fascinating. Stay well back from the blowhole and cliff edges as it is genuinely dangerous up close. The heart-shaped rock formation nearby is another fun find for kids.

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.
