Craters of the Moon National Monument and Preserve is a U.S. National Monument and national preserve in the Snake River Plain in central Idaho. It is along US 20, between the small towns of Arco and Carey, at an average elevation of 5,900 feet above sea level.
The monument is a 715,000 acres geologic wonderland. Its central feature is the Great Rift, a 62-mile long crack in the earth’s crust. The Great Rift is the source of a remarkably preserved volcanic landscape with an array of exceptional features. Craters, cinder coves, lava tubes, deep cracks, and vast lava fields form a strangely beautiful volcanic sea on central Idaho’s Snake River Plain. The Monument is jointly managed by the BLM and National Park Service.
Location: The visitor center is located approximately18 miles southwest of Arco on Highway 20 and 50 miles northeast of Shoshone on Highway 26.
