Dearborn River

About Dearborn River

The Dearborn River is a 65-mile freestone river in Central Montana, originating in the Bob Marshall Wilderness Complex. This river offers diverse fly fishing opportunities for rainbow, brown, and native cutthroat trout, with cutthroats prevalent in the upper, remote headwaters accessible only by foot or horse. The middle and lower sections, best explored by float, transition through rolling hills and dramatic canyons, holding larger rainbow and trophy brown trout. Anglers can expect consistent dry fly and nymphing action, fueled by abundant hatches of Salmonflies, Golden Stones, Caddis, and Mayflies. While access in the upper reaches requires hiking, floating is recommended for the middle and lower canyon sections, providing a picturesque wilderness experience with opportunities for both wade fishing near access points and streamer fishing in deeper holes.
