Best US Astrophotography Locations by Region

The American West dominates the list — high elevation, dry air, and vast uninhabited terrain combine to produce the darkest accessible sky in the country. But every region has strong options within driving distance for most photographers.

🏜️
Southwest: The Dark Sky Capital
Utah, Arizona, New Mexico, and west Texas have the highest concentration of Bortle 1–2 sky in the lower 48. Natural Bridges, Death Valley, Big Bend, and the Four Corners region are all within a day's drive of each other. The Southwest dark sky corridor is the best astrophotography region in the US. Check Natural Bridges →
🏔️
Rocky Mountains: High and Dry
Colorado, Wyoming, and Montana offer Bortle 2–3 sky at elevation — the thin, dry air above 8,000 feet dramatically improves transparency. Great Sand Dunes, Black Canyon, and the San Juan Mountains are the standout Colorado locations. Check Great Sand Dunes →
🌊
Pacific Northwest: Dark but Wet
Eastern Oregon and Washington are dark — Bortle 1–2 in remote areas. The challenge is weather: the Pacific Coast has the most cloud cover of any region. Steens Mountain and Hart Mountain deliver when conditions cooperate. Check Steens Mountain →
🌲
East Coast: Cherry Springs and West Virginia
Cherry Springs State Park in Pennsylvania is the darkest accessible sky east of the Mississippi. Spruce Knob and Watoga in West Virginia are also strong eastern options. East Coast dark sky requires longer drives from cities — but dedicated options exist. Check Cherry Springs →
