Dark Sky City

The first Dark Sky City in the world

In 2001 Flagstaff became the first International Dark Sky Place anywhere, recognized for decades of work keeping its night sky dark. It started with the astronomers on Mars Hill: in 1958 Lowell Observatory got the city to limit searchlights, the first lighting ordinance written to protect dark skies.

The rule is still the same: fully shielded lights that point down, and light only where it's needed.

Tips

When the sky is darkest

The darkest nights fall around the new moon. Eyes take a while to adjust, and nights are cool even in summer.

Sunset Crater

Darkest nights
Around the new moon, when there's no moonlight to wash out the stars
Clothes
Flagstaff sits at about 7,000 feet, and nights are cool even in summer. Bring layers
Lights
Use a red light so your eyes stay adjusted to the dark
Wupatki
Its trails close at sunset, so it's not a stargazing spot
Where to stay

Close to Mars Hill

Downtown and Milton Road hotels are a short drive from Lowell, so you're back in bed soon after the telescopes close.
