Ape Caves

Descend into the Ape Caves and explore the third longest continuous lava tube in all of North America. At 2.5 miles, this natural wonder was formed in an unusual lava flow more than 2,000 years ago. Since then, it's become one of the Pacific Northwest's most popular geologic attractions, with its stunning stalactites, stalagmites and unusual mineral formations. While not for everyone, this attraction is ideal for adventurous nature-enthusiasts, who don't mind a lengthy hike through one of the country's most spectacular volcanic formations.
