Glacier National Park, Montana
Fall foliage in this enormous, wild expanse of alpine forests and Rocky Mountains in Montana is quite the sight. But fall is a wonderful time to visit if you want to see wildlife, too. The National Park Service website says that there are fewer people in the park and more animals—including grizzlies, wolves, and eagles—out and about during autumn.
When to Go: Peak fall colors generally appear at the end of September and beginning of October.
