Dark Sky Parks
Glacier National Park
West Glacier, MontanaBortle 1 Best in Summer
Pristine sky, where the Milky Way casts shadows on the ground.
Glacier National Park forms the US half of the Waterton-Glacier International Peace Park, a transboundary dark sky reserve straddling the US-Canada border. The park's remote mountain wilderness in northwestern Montana produces Bortle 1 conditions in its interior valleys, far from any significant light source. The Going-to-the-Sun Road corridor provides some of the most accessible high-alpine stargazing in the country during the summer season, with glacier-carved peaks and mountain lakes as foreground.
