Gallatin River Guides

Montana fly fishing trips, guides and gear

Our Montana fly fishing trips showcase the great waters of Montana and Yellowstone Park. From our central location we fish the planet’s highest concentration of world class, wild-fish fly fishing waters. We offer day trips, lodging packages, and custom fly fishing adventures. Our year-round fly shop on the Gallatin River is our home base and we fish all of Montana’s best waters. Our online store is open all the time.

Since 1984 GRG has been a year-round source for fly fishing the Gallatin, Madison, Yellowstone, and Paradise Valley Spring Creeks. We fish a ton. That is all we do and we do it well. From beginner to expert, from the Madison River to a technical spring creek, we are your source for all things fishy under Montana’s Big Sky.

We've been serving Montana anglers for over 30 years with over 150 years combined guiding and fly fishing experience.

We’ve fished all over the world but will return again and again to fish with Gallatin River Guides and crew. We had fun and fishy guides, access to amazing public and private waters, lodging, and food that left us stuffed. These guys and gals truly live the dream, and we got to live it, too.
