Idaho Gem: Craters of the Moon National Monument

Here’s the next installment in my Idaho Gem series—places around the state that I personally love and feel are worth visiting! Idaho is full of natural beauty and fun attractions, and I wanted to showcase those in case you ever find yourself planning a trip (in a safer, post-pandemic world!).

There are so many gems to be found in the Gem State! (Sorry—I had to!)

Craters of the Moon National Monument and Preserve

Craters of the Moon is an out-of-this-world, seemingly random scenic area located in southeast Idaho within the Snake River Plain. It’s an area characterized by volcanic features that seem like something you’d find on the moon…hence the name!

It’s a basalt rock-lovers’ paradise, with a variety of volcanic features, including cinder cones, spatter cones, and lava tubes. The monument is comprised of three (relatively) young lava flows that occurred 15,000-2,000 years ago. I visited Craters multiple times as a girl scout in my younger years, and I have fond memories of exploring the caves with my friends (as well as blasting 90s pop/rock in the car, still some of the best music TBH!).

Craters of the Moon is open year round to visitors. It’s lovely in the late spring/early summer when temperatures are mild and the wildflowers are blooming, and fall temperatures are also pleasant. Mid- to late summer can be quite hot and dry, especially with all of the black basalt rock. Be sure to plan for the heat if you visit during the summer and avoid being out at the hottest time of day.

Korri and I visited Craters of the Moon most recently last fall on our way home from Grand Teton and Yellowstone. We didn’t have much time in the park, but we did manage to squeeze in a drive around the loop road with stops at Inferno Cone, Snow Cone, and the Spatter Cones. The hike up Inferno Cone is relatively quick, but you definitely don’t want to fall on the sharp basalt rocks! It would be like falling on shards of glass. Eeep! The view from the top is worth the short thigh burn.
