Yellowstone Country Fly Fishing is a Montana fly fishing guide service based in Livingston, Montana. Our Montana fly fishing guides offer personalized float, power boat, and walk & wade fly fishing trips in southwest Montana and Yellowstone Park. We love to guide experts and beginners alike.

We run a small and focused Montana fly fishing guide service. Outfitter Walter Wiese guides many trips personally, and we often use nothing but custom and local flies he designed for fly fishing Montana and the Yellowstone area.

Use the navigation bar above to learn more about the range of Yellowstone and Montana fly fishing trips we offer and to learn about the places we fish.

Visit our Montana fishing report, Montana fishing resources pages, and Montana fly fishing blog for fishing tips, conditions updates, reports from specific trips, area lodging and fishing links, and our extensive regional fishing planner.

Want to book a trip or start a conversation? Feel free to contact Walter Wiese any time. From April through October he is on the water guiding or fishing almost every day, and in the winter he’s usually snowboarding, so e-mail is usually the best way to make initial contact.
