Ape Caves: Hiking, Tours, And Cave Exploration

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 over 2,000 years ago. Since then, it has 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 long hike through one of the country's most spectacular volcanic formations. Book our Vancouver, WA, hotel near Ape caves to enjoy the most of your vacation.
