Welcome to Big Sky Trout, your complete guide service for the Big Sky area and all of Montana. Big Sky Trout is owned and operated by Ennion Williams and Brian Kimmel. Ennion and Brian have been outfitters in Montana for over 25 years and guiding over 30 years.  Big Sky Trout owns and operates under  permits on the Gallatin National Forest and the Bighole and Beaverhead Rivers.  Many of our trips are day float fising trips on the Madison and Yellowstone Rivers. These rivers are about an hour drive from Big Sky and we will cover about 7-9 miles of river in a day trip. We also have access to a  Yellowstone National Park permit which will open up the beautiful waters of our first National Park. With a vast array of rivers and lakes, Big sky Trout is able to offer the best of Montana fly fishing. Email to ennionwilliams@gmail.com for more information or to book a trip.
