Lava River Cave in Oregon
Impressive, 1,588 m long lava cave, the largest in Oregon. Rediscovered in 1889 but obsidian flakes testify to the earlier discovery of the caves by the Native Americans.
Oregon Caves
Beautiful show caves that were discovered in 1874. Caves have formed in marble and through the cave system flows a river – River Styx. The total length of passages is around 4,600 m. The cave contains valuable fossils including remnants of a grizzly bear, jaguar, and others.
Sea Lion Caves
A system of enormous sea caves with up to 38 m tall ceilings. Here lives a group of Steller’s sea lions – during the winter there are hundreds of them. Discovered in 1880.
Cave-In-Rock
Enormous, shallow cave in the limestone bluff at Ohio River. For millennia it has served as a shelter for local people. The cave with its 17 meters wide entrance is well visible from the river and has been inhabited also by local gangs – river pirates in the late 18th century and later.
Pirate Cave (Waiwaipuhi Sea Cave)
Enormous sea cave, 290 m long. It can be accessed only from the sea. Over the entrance falls a waterfall – thus every visitor gets a shower from it. During the winter, as the power of the waves increases, the entrance into the cave turns into a blowhole – the pressure of the air from the cave pushed back the waves, creating a fountain of mist and water.
