National parks protect some of the last remaining dark skies in the United States and embraces night skies as one of the many scenic vistas to preserve. Due to its remoteness and clean air, Grand Canyon National Park is one of the best night sky observation sites.
For eight days every June, park visitors explore the wonders of the night sky on the South Rim with the Tucson Amateur Astronomy Association, and on the North Rim with the Saguaro Astronomy Club of Phoenix, Arizona.
Things to Know about the 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)
Painting the flashlight lens with red nail polish or a red magic marker.
