St. Mary is near the east entrance of Glacier National Park and is situated between Lower St. Mary Lake, in Glacier County and Upper St. Mary Lake, in the park. The Going-to-the-Sun Road links St. Mary on the eastern side of Glacier with the park's western entrance at West Glacier. The area north of the lake along the road is rich in wildlife and beauty. Mule deer and elk call it home, while spring and summer offer an array of wildflowers including Indian paintbrush, blanketflowers and lupine.
