Bowman Lake is located in the corner of Glacier National Park and is accessible via a rugged 6-mile unpaved road or the Bowman Lake Trail, which overlaps the Pacific Northwest Trail. The lake is approximately 7 miles in length and 1 mile in width, making it the third-largest lake in the park. The Bowman Lake Campground on the shores has 48 campsites and is excellent for canoeing, kayaking, and fishing, with motorized boats limited to 10 horsepower or less.
