Glacier's streams and lakes are habitat for whitefish, kokanee salmon, arctic grayling, and five kinds of trout. Try the North Fork of the Flathead to fish for cutthroat and bull trout and any of the three larger lakes in the park (Bowman Lake, St. Mary Lake, and Lake McDonald) for rainbow, brook trout, and whitefish. State of Montana fishing licenses are generally not required within the park's boundaries, although you will need one on the North Fork and Middle Fork of the Flathead River. Also, keep in mind since the eastern boundary of the park abuts the Blackfeet Indian Reservation, you may find yourself fishing in their territorial waters. To avoid a problem, purchase a $10 use permit from businesses in the gateway towns; the permit covers fishing, hiking, and biking in the reservation. Fishing outside the park in Montana waters requires a state license; check in at a local fishing shop to make certain you're within the laws.
