Year-round
Overview
Montana rivers like the Missouri and Yellowstone hold trophy brown trout over 20 inches.
Fall streamer fishing (September-November) is the most exciting way to target big browns.
Matching the hatch during prolific PMD and caddis hatches produces excellent dry fly action.
Drift boat fishing allows coverage of water that wade anglers cannot reach.
