Located less than an hour away from our Battle Ground, WA hotel, the Ape Caves is a natural wonder and the third-longest continuous lava tube in all of North America. To get to this incredible Washington attraction, head north from our hotel on SW 15th Ave towards W Main Street. Then take WA-503 N and WA-503 Spur to NF-83 in Ariel. Continue on NF-83 and drive to FS-8303060 in Cougar to reach your destination.
