About Gallatin River Guides
Gallatin River Guides is the oldest fly fishing outfitter in Big Sky, Montana, having served anglers on the waters of southwest Montana and Yellowstone National Park since 1984. Their fly shop on Gallatin Road in the canyon is a genuine institution — the kind of place where visiting anglers stop in for honest fishing reports, local knowledge, and the right fly patterns before heading out to the river.
Guided trips cover the Gallatin, Madison, Yellowstone, and Missouri Rivers, as well as the spring creeks of Paradise Valley, giving clients access to some of the finest trout water in North America. Trip formats include walk-and-wade sessions on the Gallatin's pocket water, drift boat floats on the Madison and Yellowstone, and multi-day lodge-based packages that combine multiple rivers into a comprehensive Montana fishing experience. The guide team brings over 150 years of combined experience on these waters, and their ability to match clients with the right river, technique, and conditions is what separates a good day from a great one.
Beyond guiding, Gallatin River Guides operates a fully stocked fly shop carrying premium rods, reels, waders, and an expertly curated fly selection tied to match the region's specific hatches. Their casting instruction programme welcomes complete beginners, while advanced clinics refine technique for experienced fly fishers looking to improve their game. The shop's four-decade presence in the Gallatin Canyon makes it an essential stop for anyone fishing the Big Sky area.
