The Halona Blow Hole can be found on the southeast coast of Hawaii, not far from the Koko Crater. Every minute or so, ocean waves are funnelled through an underground tunnel and water bursts out of the rocks like a geyser.
Visitors can enjoy a good view of the Halona Blow Hole from the highway viewpoint that overlooks the blowhole. A second viewpoint can be found a little further down the main road.
