About
Craters of the Moon National Monument and Preserve offers an otherworldly journey through a vast volcanic landscape.
This unique national monument and preserve in Idaho protects a "weird and scenic landscape" of vast lava flows, cinder cones, and lava tube caves. Formed by eruptions along the Great Rift volcanic zone over millennia, it provides a dramatic, lunar-like environment unlike anything else in the contiguous United States. Visitors are transported to a desolate yet beautiful realm, showcasing the raw power of geological forces.
The park's 7-mile Loop Road provides access to key features like the iconic Inferno Cone, offering panoramic views, and the fascinating Spatter Cones, miniature volcanoes where visitors can peer into their vents. Venture into the underground world of lava tubes, such as Indian Tunnel, Dewdrop Cave, Boy Scout Cave, and Beauty Cave, which provide a glimpse into the subterranean formations of cooled lava. Despite the seemingly harsh environment, the area supports unique plant life, including dwarf buckwheat and various wildflowers that bloom in spring, and a surprising array of wildlife like pikas and mule deer.
Craters of the Moon is a powerful testament to the Earth's dynamic nature and a prime destination for adventure and education. Its stark beauty, geological wonders, and opportunities for exploration make it a memorable experience for anyone seeking to connect with a truly unique natural landscape. Recognized as an International Dark Sky Park, it also offers unparalleled stargazing opportunities. Eager to name that creature? Identify any animal you find during your visit using the Snappit app.
Craters of the Moon National Monument was established on May 2, 1924, by President Calvin Coolidge, to preserve the "weird and scenic landscape peculiar to itself." Early geological expeditions and the enthusiastic promotion by Robert W. Limbert, a taxidermist and avid outdoorsman, were instrumental in its designation. Limbert explored the lava fields extensively, leading scientific groups and publishing influential articles, including one in National Geographic in 1924, which vividly described the area's spectacular and unusual landscape. In November 2000, a presidential proclamation by President Clinton significantly expanded the monument's area. The 410,000-acre National Park Service portions of the expanded monument were subsequently designated as Craters of the Moon National Preserve in August 2002. The area is co-managed by the National Park Service and the Bureau of Land Management. Paleo-Indians visited the area as far back as 12,000 years ago, and the Northern Shoshone created trails through the lava field during their seasonal migrations.

Good to know before you go
Bring plenty of water
The high desert environment, especially the dark lava, can make it surprisingly hot and dry. Stay hydrated, even on short hikes.
Wear sturdy, closed-toe shoes
The volcanic terrain can be uneven, rocky, and sharp. Good footwear is essential for safety and comfort, especially when exploring caves.
Carry a flashlight or headlamp for caves: Lava tube caves are dark, and a cell phone light may not be sufficient for exploration.
Protect yourself from the sun
Bring sunscreen, a hat, and sunglasses, as there is little shade in the monument.
Plan for night skies
If possible, stay after dark to experience the incredible stargazing opportunities afforded by this International Dark Sky Park.
Check current conditions
Before visiting, especially in spring or winter, check the park's website for road closures, cave access, and facility hours, as conditions can change.
Pack layers
Temperatures can fluctuate significantly between day and night, and wind can be a factor.
