Montana Fly Fishing Outfitter River Header




MFG is a Montana fly fishing outfitter based in Livingston, Montana, which is located just north of Yellowstone National Park near many famous rivers in Paradise Valley.

We are in an area considered to be a pinnacle of fly fishing by anglers the world over. Nearly a dozen world class Montana trout fisheries are within a few miles drive. We offer a wide variety of fly fishing trips from All Inclusive Stay & Fish PackagesPrivate Spring CreeksYellowstone National Park Trips and many others.


We love sharing our knowledge of the hundreds of miles of Blue Ribbon Montana fisheries

Our home fly fishing water is the Yellowstone River, which is the longest freestone river in the country. This un-dammed river boasts the longest stretch of “blue ribbon trout stream” in the nation. With superb hatches of caddis, mayflies, stoneflies and terrestrials it’s a must on your fishing checklist. The nearby spring creeks of ArmstrongDePuy, and Nelson offer spectacular views and world class walk and wade fly fishing. Anglers from around the world travel to test wits with these selective trout. These private waters are booked years in advance, but due to our long standing relationship as a Montana fly fishing outfitter, we have a number of prime summertime rods available. See our Montana Sampler Package to learn more.

A Great Experience with MFG

We had a great experience with MFG. Eric was so easy to communicate with and so well organized. Each member of our group had nothing but great things to say about the guides they were paired with. Couldn’t recommend MFG more. Will definitely use again.

Highlight of our Trip!

This was the highlight of our trip!!!!! My mother and I went to Livingston for a mother-daughter trip. Among other things we wanted to go fly fishing. Neither of us had any experience, but had watched my grandfather enjoy it over his lifetime. We wanted to connect with him, nature and learn the skill and art. Will, our guide, has his work cut out for him. He didn’t treat us like a bunch of “silly tourists.” He truly taught us the basics, we caught multiple fish, and we had the most fun, beautiful trip down the river. I know these guys will provide serious anglers a phenomenal trip, but I will be forever grateful that they were able to create an exceptional experience for two novices. It was worth every penny….it was priceless!

Will certainly be back to utilize their services to make the most of my next visit!

MFG is for You

I have been fishing with MFGs for over a decade and would not think about using another outfitter. They are customer driven and work hard to provide you the best fishing, experience possible. Any guide can tie a fly on your line, but if you want a guide that will work hard to get you on the fish and provide you with a memorable experience, MFGs is for you.

Novice fisher-woman

As a novice fisher-woman, I did quite a bit of research on which guide to use during our time in Montana. We needed someone patient and who could give us the best bang for our buck for a half-day adventure & Montana Fly Fishing Guides did just that. Eric, the owner, was incredibly kind and flexible working with us when the weather didn’t cooperate for our initial schedule. He connected us with our guide, Andy, and we had a fantastic time on the beautiful Yellowstone River, catching a variety of trout and white fish. If you book with this group, you will not be disappointed!

“Made the Day Easy & Enjoyable”

I would call myself a beginner who has only been fly fishing for about a year and this was an awesome experience. Jesse made the day easy and enjoyable and we were able to learn a lot of new tips from him. Eric was also awesome to work with booking the day. Definitely going to recommend these guys to anyone traveling to Montana.

“You should fish with MFG!”

MFG and Josh are a class act! I am a novice fly fisherman and my wife had never fly fished. Josh took the time to teach us the basics and was excellent at teaching. Josh worked hard at keeping us on fish and we were getting bit all day! I cannot say enough good things about our experience today. If you are in Montana you should fish with MFG.

“Patient and Informative”

We were fortunate to be able to book two days of guided fly fishing with Montana Fly Fishing Guides on fairly short notice. We didn’t catch all that many fish, but Lance worked with us on improving our technique (we’ve both been fly fishing for less than a year) and was both patient and informative. Already thinking about when we can head back to Montana and fish again!

“Don't Hesitate to Book, Well Worth It”

My group of 6 spent 3 days fishing with Eric and a few of his guides. This was my first time with a guide and it was a great experience. Zack consistently put us on fish. He watched our techniques and gave us advice throughout the day which helped us land even more fish. Don’t hesitate to book these guys. Well worth it.

“Best service anywhere”

Eric Adams and his Montana Fly Fishing Guides is the best fly fishing guide service we have ever used. The Yellowstone, Boulder Creek, lots of private waters too. The guides are knowledgeable of the area and are on top of what is hatching and where to go. If you are planning on fishing in Paradise Valley these are the guides.
