Montana's Best Guided Fly Fishing & Hunting Trips

From fly fishing on world-class trout waters to hunting waterfowl or upland birds, we know how to put you in the right place at the right time to experience the best hunting & fishing Eastern Montana has to offer.

Montana Fly Fishing

Fly fishing is an art, and few places in the world offer as many world-class trout waters to practice that art as Montana does. Our experienced guides know how to navigate these rivers and put you on of some of the best trout in the world.

Upland & Waterfowl Hunting

From the boat or the banks, enjoy hunting waterfowl on the Big Horn River or step outside the waterways and into the countryside to hunt upland birds. For our hunting trips, our guides are joined with our excellent hunting dogs - trained by DD Kennels.
