Craters of the Moon National Monument and Preserve is a 750,000-acre geologic wonderland created by the Great Rift--a 52-mile long crack in the Earth's crust--and jointly managed by Bureau of Land Management and National Park Service (NPS). Craters of the Moon is a strangely beautiful and incredibly well-preserved volcanic landscape on Idaho's Snake River Plain that features exposed fissures, lava fields, lava tubes, craters and cinder cones. This landscape was formed by eruptions that started 15,000 years ago and represents the last period of volcanic activity in this area. The most recent activity occurred just 2,100 years ago, and is likely to continue in the future. Visitors to Craters of the Moon enjoy countless opportunities for hiking, camping, cross-country skiing, wildlife viewing, and backcountry travel. For casual travelers the 7-mile Loop Road and trails in the National Park Service (NPS) Monument provide easy access to a range of volcanic features. A network of primitive roads in the BLM backcountry offer driving and exploration opportunities for motorists with high-clearance, 4-wheel-drive vehicles.

Outside of the developed area of the Monument managed by NPS, there are no services and marginal phone coverage in the Monument and Preserve. Exploring these areas requires special planning and an awareness of potential hazards. Bring a map, compass or GPS, a reliable form of communication, first-aid kit, sun protection, fire extinguisher, shovel, and plenty of water, food and fuel. Always let someone know where you are traveling to and when you will return.
