One of the last true dark skies in America...

As of spring 2016, Great Basin has been designated an International Dark Sky Park! The International Dark Sky Association has recognized that Great Basin provides distinguished and significant opportunities to experience dark nights. We protect our pristine nighttime environment for scientific, recreational, and cultural values.

On a clear, moonless night in Great Basin National Park, thousands of stars, numerous planets, star clusters, meteors, man-made satellites, the Andromeda Galaxy, and the Milky Way can be seen with the naked eye. The area boasts some of the darkest night skies left in the United States. Low humidity and minimal light pollution, combined with high elevation, create a unique window to the universe.

Can you make a difference with light pollution? Yes, look at the International Dark Sky Association website.

Star Train

Great Basin National Park and the Nevada Northern Railway in Ely, NV are teaming up to offer the NNRW's Star Train! Riders begin their journey at the train station in Ely and ride the historic northern train route through Ely. Great Basin's dark sky rangers will be onboard to talk trivia, give out prizes, and answer questions. The train will stop out of town where passengers can disembark and look through high-powered telescopes to see planets, deep space objects, and more (weather permitting). The train will then return to the train station later that evening. Tickets are required. Go to Nevada Northern Railway's website to learn more about the train and reserve your spot. The trains sell out quickly.

Please contact the Nevada Northern Railway at (775)-289-2085 for 2021 dates.

Full Moon Hike

Not offered in Summer 2021
On summer nights when the moon is too bright for our regular astronomy programs, join a dark ranger for a full moon hike! These highly popular hikes start just after sunset and traverse Great Basin under a moonlit sky. The program is free, but tickets are required. You can make reservations in person at the Lehman Caves Visitor Center. All participants who wish to attend must be present in the visitor center to be issued a ticket. Participants must be at least 8 years of age or older due to the strenuous nature of the hike. Please talk to a Ranger for more information.

Solar Telescope Viewing

On select summer afternoons, join us on the back porch of the Lehman Caves Visitor Center for safe solar telescope viewing of our closest star, the Sun! Great Basin has state-of-the-art solar telescopes to view sunspots, prominences, filaments, and magnetic storms. Fun for all ages.
