Ultimate Travel Guide: 24 Hours in Craters of the Moon National Monument

A Spontaneous Detour to Craters of the Moon

During this road tour we’re all for spontaneous detours that lead to epic adventures, and discovering Crater’s of the Moon National Monument & Preserve after leaving Salt Lake City, blew our minds and our van doors wide open! This hidden gem wasn’t on our 6-month itinerary or our radar, but we happened to see it on Google Maps as we made our way from Salt Lake to Boise so we made a small detour to Arco, Idaho and spent 24 hours exploring this unique natural wonder!

This blog is your guide to discovering the other-wordly landscapes of Craters of the Moon National Monument & Preserve in Arco, Idaho. From fascinating volcanic features to lava tubes and spatter cones, this unique natural attraction is (in our opinion) one of the most underrated National parks that you NEED to add to your bucket list.

The Unique Geology of Craters of the Moon

Craters of the Moon National Monument & Preserve isn’t your typical national park. Volcanic activity over the past 15,000 years has carved a unique terrain of lava flows, cinder cones, and lava tubes. The park’s name is inspired by its lunar-like appearance, which made it an ideal training ground for NASA astronauts in 1969. To learn more about its fascinating history, explore the park’s website.

Today, you can experience the desolate beauty of Craters of the Moon by camping, hiking, and exploring its unique geological formations. During our visit, we hiked up cinder cones, peered into spatter cones, ventured into deep lava tubes and caves, camped under a star studded sky in our Vandoit, and explored the visitor center to learn about the park’s history and geology. As a designated International Dark Sky Park, Craters of the Moon National Monument boasts some of the darkest skies in the country – perfect for stargazing enthusiasts like us!
