Bighorn River Fly Fishing at Its Finest

When it comes to Bighorn River fly fishing, few destinations can match the quality, consistency, and beauty of Montana’s legendary Bighorn River. Widely regarded as one of the finest trout fisheries in North America, the Bighorn offers exceptional fishing opportunities for anglers of every skill level.

The river begins below Yellowtail Dam near Fort Smith, Montana, and flows north through the scenic Bighorn Valley before joining the Yellowstone River. Its cold, regulated flows create ideal trout habitat and provide some of the most dependable fishing conditions in the country.

The most famous stretch of water runs from the Afterbay to Bighorn Fishing Access. Known simply as the “A to B,” this iconic section attracts anglers from around the world. While we fish this stretch regularly, River Rock Outfitters specializes in the quieter, less crowded sections of the lower river. These secluded waters offer a more personal experience and the opportunity to enjoy fly fishing Bighorn River Montana in relative solitude.

Whether you’re an experienced angler or picking up a fly rod for the first time, success comes quickly on the Bighorn. Landing healthy rainbow and brown trout is common, and trout over 20 inches are caught every season.

Premium Fly Fishing, Gear, & experiences

Every guided trip includes professional drift boats, quality equipment, and everything needed for a successful day of bighorn river fly fishing. Our guides adapt to changing conditions using a variety of techniques, including dry flies, nymphs, and streamers, ensuring a well-rounded and productive experience.

All fishing is catch and release because we believe healthy trout populations are what make this fishery so special. If you arrive without gear, don’t worry. We provide rods, reels, flies, tackle, waders, lunch, and drinks, so you can simply show up and enjoy the day.

The Bighorn River is a tailwater fishery fed by the cold depths of Yellowtail Dam. Unlike many Montana rivers that become muddy and unfishable during spring runoff, the Bighorn remains remarkably clear and consistent throughout much of the year. This creates outstanding fishing opportunities from spring through fall and helps make fly fishing Bighorn River Montana one of the most sought-after experiences in the West.

It’s common for anglers to land multiple trout throughout the day, regardless of experience level. For those looking for something even bigger, we also offer limited opportunities to pursue trophy trout exceeding 24 inches during select times of the year.
