The Gallatin River begins at Gallatin Lake, which is located high in the mountains of the Gallatin Range in Yellowstone National Park, and flows for 115 miles to its end at the beginning of the Missouri River in Three Forks. Throughout its length, the Gallatin River offers a very wide variety of water, excellent river access, relatively low fishing pressure and gorgeous scenery.Once the Gallatin River leaves Yellowstone National Park, the river flows through very mountainous country, with steep mountains towering above the river. Extensive whitewater stretches are found on the Gallatin River, particularly downstream from the town of Big Sky. The Gallatin River for much of its length is not a very large river. As a result, float fishing on the Gallatin River from Yellowstone National Park downstream to the confluence with the East Gallatin River is not allowed, a distance of more than seventy-miles.
Since the bulk of the Gallatin River is closed to float fishing (but not recreational floating), the Gallatin is a dream come true for wade anglers who are frustrated by having to share the water with lines of rafts. Coupled with the excellent access found in the upper half, the Gallatin ranks as one of the finest wade fishing rivers in Montana.After traveling for more than forty miles through mountainous terrain, the Gallatin River leaves the mountains behind as it spills out into a broad, scenic valley, which also contains the towns of Bozeman, Belgrade and Manhattan. Once the Gallatin River leaves the mountains, it begins to flow primarily through private land. While a number of access sites do exist, access is significantly more difficult on this section. Unless you purchase our house, which gets you private access to the Gallatin downstream from the Erwin Bridge fishing access point and the ability to fish all the way down to the Manhattan bridge, a great daylong adventure! :)
