Fly Fishing the Clark Fork

The Clark Fork River is a tributary of the Columbia River and runs for over 300 miles through Western Montana. It is home to a variety of fish species, including rainbow trout, brown trout, cutthroat trout, and mountain whitefish. The river is surrounded by beauty, with the Cabinet Mountains to the north and the Bitterroot Range to the south.

We highly recommend floating this river. A raft or drift boat offers access to parts of the river that are otherwise difficult to reach when wading. The Clark Fork River has some challenging sections, and a raft is best used to navigate them, giving anglers access to some of the best fishing spots on the river allowing anglers to target them with precision. Whether you’re fishing with dry flies, nymphs, or streamers, the Clark Fork River is a fly fisherman’s paradise.
