Best Time to See the Milky Way in Montana

Montana is one of the best states in America for Milky Way viewing. With vast wilderness areas, low population density, rugged mountain ranges, and some of the darkest skies in the lower 48 states, Montana offers extraordinary opportunities for stargazing. Whether you are exploring Glacier National Park, the remote plains of eastern Montana, or the mountain valleys of the Rockies, dark skies are never far away.

The best time to see the Milky Way in Montana is generally from May through September, with peak viewing conditions occurring during June, July, and August. During these months, the galactic core remains visible for long periods and rises high above the horizon.
