Arizona has 24 certified dark sky places in our directory: ten dark sky parks, one dark sky sanctuary, two urban night sky places, nine dark sky communities and two certified lodging properties.
The names to know: Grand Canyon National Park (certified 2016), Petrified Forest National Park (certified 2018), Chiricahua National Monument (certified 2021), and Flagstaff, Arizona (certified 2001).
The DarkSky International place types guide (opens in new tab) describes a dark sky park as land with notably dark, star-filled skies that is protected for its scientific, natural, educational, cultural or recreational value.
Check the moon phase before you book. A full moon makes faint objects much harder to see, as Great Basin National Park's stargazing page (opens in new tab) points out. Summer nights show the Milky Way at its densest, and winter brings Orion and the Pleiades (Great Basin National Park (opens in new tab)).
Before you go, see the Arizona dark sky laws for how local lighting rules protect these skies.
