Bortle 2 sites in the U.S.

List of Class 2-3 Bortle parks and places in the U.S. Bortle 2 are the second-darkest skies on Earth for stargazing, astrophotography, star parties, and club events. Often these are national and state parks and forests that are remote or "protected" against light pollution.

A Bortle value represents the potential of a location, not what it will be when you are there. Local factors such as dust, wildfire smoke, haze, humidity, clouds, or atmospheric turbulence can diminish the Bortle value that night.

The IDA column indicates if a site is an IDA-certified sanctuary, reserve, or park. Also use your local astronomy club for guidance as they will know the darkest places near you.
