Running the western boundary of Glacier National Park near Polebridge, the North Fork Flathead River provides drainage for many lakes and creeks including Bowman Lake and Kintla Lake. The North Fork Flathead River meanders through a broad, scenic valley on its way south. It is one of the most beautiful places in the US. In the river, expect to find cutthroat trout and rainbow trout, occasionally. Luckily, this place is beautiful, because the fishing can be sporatic. Certainly this river is not for those expecting trophy size trout.
The north fork road parallels most of the river, which is perfect for waders. While most fly fisherman wade this river, a nice section to float is the 13 miles from Big Creek to Glacier Rim. If that is too short for you, a long float is from Polebridge to Glacier Rim.
Note: Bull trout may cruise these waters and it is illegal to intentially fish for them.
Keep an eye out for brown bears who would love to steal your catch!
Overall, North Fork Flathead River is the 4th most popular fly fishing river of all 21 fly fishing spots in Montana.
