Craters of the Moon National Monument: An Out-of-This-World Experience
Craters of the Moon National Monument is unlike anywhere else on Earth. Its alien-like landscape is so extraordinary that NASA uses it to train astronauts for future moon and Mars missions. The name really couldn’t be more fitting.
My visit here was a major highlight of my travels through Idaho, and I hope to inspire you to make it a highlight of your journey as well.
About Craters of the Moon NM
Established in 1924, this Monument and Preserve protects over 753,000 acres of volcanic landscape in Idaho. It encompasses three major lava fields and, in 2000, an additional 400,000 acres were designated as Craters of the Moon National Preserve.
Accessible by only a few roads, most of the park remains a pristine wilderness under the Bureau of Land Management. Some areas are accessible by high-clearance 4WD vehicles.
While humans have traversed this area for millennia, there’s no evidence of long-term settlement. Early settlers, wary of Native American attacks, trekked north through the lava beds, enduring a treacherous journey. The land gained more popularity when explorers Robert Limbert and W.L. Cole highlighted its wonders through photography and detailed accounts, culminating in a National Geographic feature that led to its designation as a National Monument.
Must-See Spots
1. Loop Road
The best way to see the park is by taking the 7-mile Loop Road, which highlights several key sights. If you miss a spot, you’ll need to loop around again.
2. Lava Tubes
Explore the fascinating lava tubes and wild caves. Four of these tubes are open to the public, but you need a permit. Check out the “Wild Caves” section for details.
3. Splatter Cones
Created from short bursts of airborne lava, these intriguing small cones can be seen along the Loop Road. Stick to designated trails to preserve their fragile states.
4. Devil’s Orchard
This area offers a unique view of broken lava pieces scattered across a blackened landscape. It’s a great place to wander, explore, and snap photos.
5. Inferno Cone
Rising 164 feet, Inferno Cone offers panoramic views of the park. The hike is a bit strenuous due to the ash composition, but the vistas from the top are well worth it.
Hiking Adventures
Craters of the Moon offers various hiking trails, suitable for different skill levels. In summer, be mindful of the heat and pack plenty of water, sunscreen, and sun-protective clothing. Let someone know if you’re hiking less-trafficked trails.
1. Broken Loop Trail (1.8 miles)
An easy-to-moderate hike that showcases the park’s volcanic features. Be prepared for hot conditions in summer.
2. Hiking up Inferno Cone (0.4 miles each way)
Despite its short distance, this trail demands effort due to the cinder ash terrain. The views and fascinating plant life make it worthwhile.
3. North Crater Trail (3.5 miles round trip)
This trail takes you along the north crater, into its mouth, and through ancient lava vents. Starting either near the Loop Road entrance or near Splatter Cones, it offers an immersive experience into the park’s volcanic past.
4. Tree Molds Trail (2 miles round trip)
Discover the remnants of trees ignited and knocked over by lava. The trail offers unique views of these natural imprints.
