About Grand Canyon
The Grand Canyon became an International Dark Sky Park in 2019, and it's one of the great stargazing experiences anywhere — the same rim that gives you a two-billion-year view down into the canyon by day gives you an equally deep view up into the sky by night.
What you can see in the sky
Milky Way, meteor showers, and — with the canyon as foreground — some of the most photographed night skies in the National Park System.
Best time of year
New moon, especially during the park's annual summer Star Party.
Why this site is worth the drive
International Dark Sky Park since 2019
South Rim's Desert View Watchtower and Mather Point are established viewing spots
North Rim's Bright Angel Point is quieter and equally dark
Practical tips for Grand Canyon
Stargazing is best about 1.5 hours after sunset and before sunrise
The annual Grand Canyon Star Party (June) brings amateur astronomers and telescopes to both rims
Rim edges are unfenced in many spots — use a red headlamp and watch your footing
