Lanai lookout blowhole
Small blowhole that creates a fountain at certain wind and wave directions.
Makena Blowhole
Small blowhole in one of the most recent lava flows on Maui.
Toilet Bowl in Oahu
Large hole in the rocks. With each wave, the level in this hole rises and then falls again through a cave. During storms here might rise fountains of water. Earlier this was a beloved swimming place, albeit dangerous. Now it is fenced off.
City of Arches at Honaunau Bay
Some 3 km long stretch of sea shore with numerous interesting geological formations in pahoehoe lava: natural arches, sinkholes and also several blowholes.
Spitting Caves in Oahu
Sea caves with blowholes. As the wave enters the cave, air pressure forces a slanted fountain of mist and water.
Cozumel Blowholes
Two blowholes in lava fields. Usually the fountains are not too powerful and visitors often love to stand in them.
The Spout in Newfoundland
Enormous, wave-powered fountain in a beautiful natural setting – on the cliffs next to a waterfall of Spout River. Unusual blowhole as it is located rather high above the sea and, reportedly, has freshwater in it.
Spouting Horn at Cook’s Chasm
Impressive blowhole that creates a tall, hissing fountain when a wave enters Cook’s Chasm. The fountain is up to 12 – 14 m high.
Thor’s Well
Hole in the rocks at the sea that looks as if the ocean is drained in it. This is some 6-7 m wide hole, also 6-7 m deep. It is at its most impressive approximately one hour before the high tide. At high waves, it creates several meters high splashes.
Depoe Bay Spouting Horn
Interesting, quite active blowhole next to the road. It creates up to 9 m high fountains that often pour on the cars that are passing by.
