The Clarks Fork Guest Ranch is at the epicenter of thousands of miles of blue ribbon trout streams and rivers and within easy access of hundred of trout filled lakes. While the native trout is the Yellowstone Cutthroat, there is a wide variety of other species including Brown, Rainbow, Brook, Greyleen and Lake Trout. The Clarks Fork Guest Ranch can arrange guided day fishing expeditions.

Fishing float trips down the lower reaches of the Clarks Fork River provide an exceptional opportunity for serious anglers to fish sections not accessible by road or off road vehicle.
