Tour Overview
A Scenic Freestone River Built for Montana Fly Fishing
The Bitterroot River begins near Conner, Montana, where the East Fork and West Fork of the Bitterroot come together. From there, it flows north for roughly 84 miles through the Bitterroot Valley before joining the Clark Fork River near Missoula. Along the way, the Sapphire Mountains rise to the east and the Bitterroot Mountains frame the west, creating one of Western Montana’s most scenic river corridors.
The Bitterroot is a freestone river, with much of its flow coming from mountain snowmelt. Known for strong trout habitat, beautiful surroundings, and productive fly fishing, the river averages around 700 trout per mile, with large trout over 23 inches caught each year. It offers the kind of setting anglers dream about: clear water, riffles, pools, glides, mountain light, and enough variety to keep every day on the river interesting.
One of the river’s defining traits is its approachable depth. In many stretches south of Florence Bridge, the Bitterroot averages around three feet deep, even though it can be more than 125 feet wide in places. This gives wading anglers the feel of a smaller stream while still offering the size, structure, and fish potential of a larger Montana river.
Freestone Trout River
Fed largely by snowmelt, the Bitterroot is a classic freestone river with changing seasonal flows, riffles, pools, glides, and productive trout habitat.
Bitterroot Valley Views
The river flows between the Sapphire Mountains and Bitterroot Mountains, offering scenic views throughout its northbound journey toward Missoula.
Wade Fishing Access
With many shallow sections and approachable crossings, the Bitterroot gives anglers excellent opportunities to cover water on foot.
Upper & Lower River
Above Bell Crossing, the river has more gradient, riffles, and pools, while the lower river offers broader glides and a different fishing rhythm.
Fly Fishing Character
The Bitterroot River's south-to-north flow, freestone character, mountain scenery, and healthy trout population make it a favorite for both local anglers and visiting fly fishermen.
Sections, Access & River Style
The upper Bitterroot, generally above Bell Crossing, has more gradient, riffles, and pools, creating a classic Montana trout river feel. The lower Bitterroot features longer glides with larger riffles between them, offering a broader and more technical style of fishing.
Wading, Floating & Boat Considerations
The Bitterroot’s moderate average depth makes it especially appealing for wade anglers, who can often find places to cross or work both sides of the river within a short distance.
