Experience Outer Space Right Here in the U.S. at Craters of the Moon National Monument and Preserve

Located in central Idaho, Craters of the Moon National Monument and Preserve lets visitors traverse lunar-like landscapes without leaving the planet. The name "Craters of the Moon" suggests an otherworldly adventure, and it’s not just a clever title—Apollo astronauts explored this area in 1969 as part of their training for space missions. Scientific research permits are still available in the park today.

Though it may initially appear uniform, the geologic diversity found in the park's cooled lava tubes and rivers will amaze you. Instead of large volcanoes, you’ll encounter approximately 25 smaller "cinder cones," each classified as its own distinct volcano. These volcanic formations are dormant rather than extinct, so there’s no need for concern about eruptions in the near future.

Activities to Enjoy at Craters of the Moon National Monument and Preserve

Experience "Mars on Earth"

Explore the monument's otherworldly scenery along the seven-mile loop road. While the drive is relatively short, be sure to stop and snap photos at various viewpoints. You'll also find numerous trails leading to volcanic features that start from the road. Don't miss the opportunity to view large craters and delicate spatter cones at stop 5 along the loop.

Embrace the Lava

From intriguing lava bombs to the unique formations of pahoehoe lava, the site offers an impressive variety to discover. At stop number 2 on the loop road, known as North Crater Flow, you can hike the steep North Crater Trail to look directly into a lava vent. Stop 6 features block lava — large, rough-edged lava formations that appear smoother than other types found in the park.

Become a Junior Lunar Ranger

At Craters of the Moon National Monument, children can complete a fun and educational activity book to earn a stylish patch. If you finish the booklet after the visitor center has closed, you can simply mail it in to receive a junior ranger badge at home.

Explore a Cave

The monument features a limited number of caves that are accessible to the public. While the bats inside are fascinating, they are at risk from a harmful fungus that leads to White-Nose Syndrome. Although humans don't get infected, they can carry the fungus. Therefore, cave permits are issued only after visitors undergo a screening with park staff. The cave area is located at the final stop on the loop road.

Visit During Wildflower Season

Each spring, vibrant carpets of wildflowers burst forth, breathing life into Craters of the Moon. The peak bloom typically occurs from late May to mid-June, but the syringa, Idaho's state flower, showcases its beauty in mid-summer. Despite the harsh, seemingly desolate environment, these stunning flowers return yearly, demonstrating their resilient spirit.

Gaze at the Night Sky

Due to light pollution, two-thirds of Americans can no longer see the Milky Way from their own backyards. However, Craters of the Moon boasts some of the darkest skies in the national park system. There are Star Parties every fall and spring, and during summer, you can join ranger-led hikes under the full moon throughout the preserve.

Ascend a Mountain of Ash

Reaching the Inferno Cinder Cone viewpoint from the parking area takes a bit of effort, but the journey is worthwhile. Be prepared for windy conditions along the path, so keep a tight grip on your hat! At the summit, you'll be rewarded with breathtaking views of numerous cinder cones set against the dramatic backdrop of the Great Rift.

Accommodations Near Craters of the Moon National Monument

A 42-site campground stretches across the volcanic landscape just beyond the visitor center. This campground operates on a first-come, first-served basis, with a nightly fee of $15 during the season. While there are no accommodations within the park itself, you can find various lodging options and services 18 miles east in Arco.

For a unique and memorable experience in Idaho, consider booking a stay three hours away in Pocatello. Here, you can explore the Museum of Clean, an interactive and unexpectedly inspiring complex that highlights the importance of cleanliness.
