Craters of the Moon National Monument


The Craters of the Moon National Monument was established in 1970 and was expanded in 2000 to include the Bureau of Land Management’s 495 000 acres of land that was adjoining the monument, which are now designated as part of the wilderness and national park area. The BLM land remains undeveloped and provides an excellent natural area for wildlife habitat and backcountry recreation. The Craters of the Moon National Monument and preserve now has a total of 750000 acres of unique geological wonders centered along the Great Rift, a 52 mile long crack in the earth's crust which results in a volcanic landscape complete with fissures, lava fields, lava tubes, craters and cinder cones on the Snake River Plain in Idaho.

Recreational use of the Bureau of Land Management backcountry is permitted, but limited, and requires overnight camping permits for backcountry users. Visitors to the backcountry area should be prepared for primitive conditions, and as a result, the area is largely undisturbed and secluded, ideal for visitors that want a truly natural experience. The climate at Craters of the Moon is characterized by extremes with hot summers and cold severe winters. It should be noted that the area is snow-covered for ⅓ of the year and mostly inaccessible. Visitors looking to access the BLM backcountry at Craters of the Moon mostly use the Wilderness Trail and the camp at Echo Crater. Equestrians can use the trail for day use only, no overnight camping with horses is permitted in the backcountry.

The Bureau of Land Management areas feature rough terrain with occasional extreme weather conditions.

Dark Sky Viewing

Craters of the Moon is a designated International Night Sky Park. In remote wilderness areas in the BLM sections of Craters of the Moon National Monument visitors can enjoy dark sky viewing where excess “light noise” is reduced and does not impair the visibility of the night sky as much as in more populated areas. View the heavens with the naked eye, binoculars, or portable telescopes from remote areas. In the main section of the monument, “Star Parties” are held during the spring and fall seasons, hosted by the Idaho Falls Astronomical Society, which provides telescopes to enhance viewing of the night sky features.


For a unique adventure ar Craters of the Moon try some “spelunking”, the term used for cave exploration. There are five caves open for exploration in the monument, four of which are located along Caves Trail and the fifth on the Broken Top Loop Trail. Other caves in the monument and BLM areas are not open to the public due to sensitive bat populations and hazards.

The four caves along the Caves Trail are Indian Tunnel, which is 800 feet long with stairs providing easy access, Dew Drop Cave and Beatify Cave, which have bouldered entrances and are moderate in difficulty, and Boy Scout Cave, which is rated as difficult and has a tight rocky entrance. The Buffalo Cave on the Broken Trail Loop has a tight rocky entrance and is rated as difficult.

Cave guides can be found at the trailheads to the caves. You will need to obtain a caving permit at the visitor center, where visitors are screened for white-nosed syndrome which can affect local bat populations. Please do not bring shoes or other items that have been in other caves of mines. Do not bring food or leave trash in caves to protect the sensitive ecosystem.

r backcountry destinations also have primitive camping opportunities.
