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.

  • Campground or lodging reservations are recommended.
  • 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)

  • Painting the flashlight lens with red nail polish or a red magic marker.
