Local Guides - Local Waters - Experience makes a difference! Under the same ownership since its establishment in 1981, Madison River Outfitters sets the standard for professionalism and service for guided fly fishing. For the Madison River Outfitters guide staff, service means working hard, with patience and determination, to show our guests a productive and memorable day of fishing. Our outfitter and most senior guide each have more than 40 years of experience guiding and outfitting fly fishing trips in Montana and Yellowstone Park.
