Our Big Sky, Montana Fly Fishing Guides

We love what we do and want to share our passion with you.

Because of our location in Big Sky, we are a year-round guide service, and our guides work in every month of the year, in all types of weather. This means our fly fishing guides log more days on the water than any other Montana fly fishing guides.

With over a hundred years combined guided experience, our crew works with all abilities of anglers. We love guiding beginners and helping them discover fly fishing. Our expertise allows us to work with experienced anglers, offering them new tips and techniques. We know the waters of Montana and can take experienced anglers to all corners of the state, creating a new brand of fly fishing for these seeking new fishing horizons.

All of our guides are licensed with the state of Montana and trained in First Aid and CPR.

Why isn't my guide listed?

Well, the guides listed above are considered our “core guides” and work mostly for Gallatin River Guides and maybe a few other folks. Most Montana fly fishing guides are independent contractors and work for a variety of outfitters.

When all of our core group guides are booked, which happens most days during our peak season, we have created a large stable of extremely qualified, professional fishing guides and outfitters who work for us and other shops and outfitters. We personally vet all of our Montana fly fishing guides.

These guides will work very hard for you and ensure you have a great time on the water. We hold our non-core guides to the same high standard as our core guides. Fish with them. You’ll be glad you did.

We love what we do and want to share our passion with you.

Because of our location in Big Sky, we are a year-round guide service, and our guides work in every month of the year, in all types of weather. This means our fly fishing guides log more days on the water than any other Montana fly fishing guides.

With over a hundred years combined guided experience, our crew works with all abilities of anglers. We love guiding beginners and helping them discover fly fishing.
