Our goal is to provide the best fishing experience possible. We tailor our guided fishing expeditions to your desires and the time of year and offer a multitude of fishing opportunities throughout the greater Montana and Idaho regions, using a variety of boats to access the best fishing opportunities.

Fly Fishing Guide Montana Idaho Steelhead On the Clearwater Fishing

Spring Fishing, Clearwater River

Our year typically starts on the Clearwater River in Idaho, fishing for steelhead from January through early March. Once the snow and ice in Montana begins to melt, we begin exploring the principal rivers in the Missoula area: the Blackfoot, Bitterroot, and Clark Fork rivers.

We also extend our tour range to the acclaimed “Land of the Giants” section of the Missouri River, where the river flows are unaffected by the spring snow melt. The Land of the Giants is where the big trophy fish you hear of typically come from. The quality of fish is excellent, but using a jet boat is essential for accessing the best fishing areas.

Once the spring melt is over, our guests can enjoy the classic fly fishing experience offered by the local Missoula rivers, augmented by fantastic weather, amazing scenery, and a rich mix of local wildlife. We offer guided fly fishing tours on the Bitterroot, Blackfoot, and Clark Fork rivers. These rivers offer an abundance of rainbow, cutthroat, and brown trout.

Summer Fishing

In late summer, when the weather has heated up and the rivers begin to warm, we turn our attention to Montana’s undiscovered gem: the lower Clark Fork. Many of our clients enjoy this unique experience. Using our jet boat, we access hidden fishing holes that offer excellent access to pike and smallmouth bass.

Idaho On the Clearwater fly Fishing

Fall & Winter Fishing near Missoula, Montana

During the fall months, dry fly fishing again reigns supreme near Missoula, and we offer a variety of trout fishing trips to the Land of the Giants on the Missouri. We also begin to offer pike fishing on the Clark Fork River, and steelhead fishing on the Clearwater River in Idaho again.

If you’re looking for an excellent fishing experience, look no further. It would be our pleasure to craft a personalized tour.

  • Best Steelhead fishing on the planet and Scott is one of – if not the best – guide. Steelhead or Salmon.

    - Don Lathrum

  • Highly recommend a trip with Scott. Extremely knowledgable and will go the extra mile to put you on fish.

    - Greg Matthews

  • I live in Missoula and have fished the area extensively. That said, Scott has introduced me to many new options and has made fishing the area a lot more fun. He is the most resourceful fishing guide that I have met by far and my guests all love being in the boat with Scott.

    - Rellen Stewart

  • Scott Willumsen is an outstanding guide and outfitter. For the past several years, he has organized yearly outings with me and friends who come from Kentucky, Michigan, and California to fish our local waters, and they keep coming back for more. We always have a great time, and it couldn’t be better!
