Craters of the Moon / Arco KOA Journey

Located near the otherworldly landscape of Craters of the Moon National Monument, this KOA Journey offers an exceptional base for exploring one of Idaho's most unique geological wonders. The area surrounding Arco presents a landscape unlike anywhere else in the continental United States, where ancient lava flows have created a stark and mesmerizing terrain that feels almost extraterrestrial. Visitors often describe standing among the dark volcanic rock formations as stepping onto another planet, making it a bucket-list destination for geology enthusiasts, nature photographers, and adventure seekers.

The Craters of the Moon National Monument spans over 53,000 acres and features miles of hiking trails that wind through lava tubes, cinder cones, and expansive lava fields. The Great Rift, spanning 52 miles, showcases the raw power of volcanic activity frozen in time. Whether you're a casual walker or an experienced hiker, there are trails suited to every fitness level, from the easy one-mile loop around the visitor center to more challenging treks into the backcountry.

The nearby Experimental Breeder Reactor Number One, the world's first nuclear reactor to generate electricity, represents a significant chapter in American industrial heritage. This unique attraction draws history buffs and curious travelers interested in learning about the dawn of nuclear energy.
