Beartrap Canyon
Beartrap Canyon is a wilderness canyon accessible only by foot or raft holding some of the largest brown trout in the Madison system.

💧 Ideal flow: 800–2,000 CFS. Beartrap Canyon is remote and powerful — only accessible at lower flows when the canyon is safely wadeable.

About Madison River Fishing
The Madison River is legendary for its continuous, boulder-strewn "50-mile riffle" that stretches from Yellowstone National Park through Ennis—a freestone masterpiece where current and structure dominate the entire character of the water. This is one of America's most storied trout rivers, where world-class hatches and aggressive fish have defined modern fly fishing for generations.
Best Time to Fish Madison River
The Madison's salmonfly hatch (typically late May through early June) is the river's most famous event, drawing anglers from across the country for massive dry fly opportunities. Summer brings prolific caddis and PMD hatches that sustain excellent fishing through July and August, with evening rises often the most productive windows on this particular water.
Species
Brown trout dominate the Madison's deeper runs and canyon sections, where they grow large and selective on the river's abundant food sources. Rainbow trout thrive throughout the shallower, faster currents of the 50-mile riffle, where they're known for their aggressive takes and acrobatic runs in the Madison's swift current.
Access & Regulations
Always check the current Montana fishing regulations before heading out. Regulations on Madison River may include special catch-and-release sections, artificial-only stretches, and seasonal closures. A valid Montana fishing license is required.
