Glacier National Park is bordered by two pristine rivers – the North and Middle Forks of the Flathead River. The Middle Fork originates in the Bob Marshall Wilderness Area, and is known for its pure headwaters and mineral rich aqua-colored water during runoff season in the spring. The North Fork flows from Alberta, Canada, offering 84 miles of calmer water and sweeping vistas of the craggy peaks of the northwestern section of Glacier Park.
Early season flows result in exhilarating class II and III rapids. We recommend a guided half day, full day or overnight trip with trusted outfitters Glacier Raft Company or Great Northern Raft Company in West Glacier. When the mountain spring runoff subsides, our rivers become crystal clear and are quite popular to float, kayak, fish, picnic and recreate on our warm Montana summer days.
The North and Middle Forks converge at Blankenship Bridge to form the beginning of the Flathead River and is joined 8 miles downstream by the South Fork of the Flathead, flowing out of the Hungry Horse Reservoir. The river then becomes wide and flat, meandering and braiding its way to Flathead Lake in the Flathead Valley.
