During the 2025 Star Party, the last Village Route (blue) shuttle bus leaves Grand Canyon Visitor Center at 8:30 pm, so consider driving and parking in one of the Visitor Center lots. The closest accessible parking is in lot 4. Lots 1 through 3 offer additional parking with a short walk.

The South Rim Star Party is sponsored by the Tucson Amateur Astronomy Association.

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.

A light source is recommended for the walk to the viewing area, but white lights are not permitted on the Telescope Lot. Give your eyes time to dark-adapt, or use a red flashlight, easily made by covering any flashlight with red cellophane.
