Priest Lake State Park Unique Astronomy Site

Priest Lake State Park Idaho


Priest Lake State Park is a Bortle 2 scale site with excellent dark skies due to its distance from cities and other light pollution. The park lies just 30 miles from the Canadian border, nestled deep below the crest of the Selkirk Mountains. Surrounded by the natural beauty of Northern Idaho and mile-high mountains, Priest Lake State Park sits along the eastern shores of Priest Lake, a 19-mile long, 300-foot-deep waterbody.

There are dense forests of cedar, fir and tamarack and will be able to observe the park’s year round inhabitants such as the whitetail deer, black bear, moose and bald eagles. Noted for its extremely clear water, fed by streams cascading from the high Selkirk peaks, the main body of Priest Lake extends north-south for 19 miles. A two-mile thoroughfare connects the main lake to the remote Upper Priest Lake that is accessible only by foot, mountain bike, or boat.

A $7.00 Motor Vehicle Entrance Fee (MVEF) is required for every vehicle entering Idaho State Parks (including visitors to campers). Places for astrophotography or astronomy will be along the lakes and clearings.
