Stargazing at Craters of the Moon

The dark skies of Craters of the Moon showcase thousands of stars each night.

Craters of the Moon is located in one of the darkest areas of the continental US. Its distance from large cities and vast areas of undeveloped wilderness mean that on a clear night, most visitors have no problem viewing the stars. In 2017, Craters was certified as an International Dark Sky Park by DarkSky International. The night sky is one of the park's most spectacular sights and best kept secrets.

Special Events

Each summer, the park offers evening programs at the campground including astronomy programs and constellation tours. These programs usually occur July through September as staffing allows. Non-campers are welcome to attend!

Visitors can also tour the heavens by attending a Star Party, held each summer and fall. Volunteers from the Pocatello Astronomical Society and others provide telescopes and sky viewing expertise. Star Parties are popular events which attract hundreds of people every year.

For information on upcoming activities and events, check the park's event calendar or contact the park. Both evening programs and Star Parties are free to attend, but parking may be limited.

What To Bring When Stargazing

• A star map such as a planisphere or a phone app. Handouts featuring visible constellations are available from the visitor center for each season.
• Warm clothing for cooler nights
• A red flashlight. It takes much longer for your night vision to return after looking at white light than red.
• A chair or blanket to sit on
• Friends and family
• Food and water
• Binoculars (optional)

When to Go

There are certain times of the month and year that can be better than others. Make sure you check the lunar cycle and go out on or close to a new moon or before moonrise. A smaller moon allows you to see more stars. Don't forget to check the forecast. Nothing ruins a night of stargazing like clouds or inclement weather.

The best time to begin stargazing is about 1.5 to 2 hours after sunset. The Milky Way becomes visible about 2 hours after sunset.

Where to Go

Cities and towns produce light pollution that block out dimmer stars and planets. Fortunately, Craters of the Moon is far enough from brighter areas that most places in the park are suitable for stargazing. The Loop Road is open 24 hours from spring through fall, so visitors can view the night sky from their campsite or at one of the parking areas along the Loop Road. Some of the most popular places to stargaze are Devil's Orchard, Inferno Cone, and the Spatter Cones. Remember: Camping is only allowed in the Lava Flow Campground or in the backcountry with a permit.

Due to the uneven, jagged landscape and possibility of getting lost, it is not recommended to hike trails after dark.
