Grand Canyon National Park is one of the best places in the world to enjoy pristine night skies.
Not able to attend Grand Canyon Star Party? No worries! We offer astronomy programs year-round! Check out our Upcoming Night Sky Events page.
Things to Know about the 2025 Star Party
Attend this free, open to the general public, event. The park entrance fee, is good on both South and North rims for 7 days. No additional tickets or sign-up is required.
The event begins at sunset, although the best viewing is after 9 pm and many telescopes come down after 11 pm; however, on nights with clear, calm skies, some astronomers continue sharing their telescopes into the night.
Dress warmly. Temperatures drop quickly after sunset—even during summer months.
View an assortment of planets, double stars, star clusters, nebulae and distant galaxies by night, and perhaps the Sun or Venus by day.
Skies will be starry and dark until the moon rises the first night. It rises progressively later throughout the week of the Star Party.
Bring a Red Flashlight
Make your way safely: use a red flashlight; white flashlights and cell phone lights are discouraged on the telescope lot. Make a red flashlight by:
Covering any flashlight with red cellophane, a limited supply of cellophane and rubber bands are available prior to the evening presentations at the Grand Canyon Visitor center)
