For many die-hard enthusiasts fly fishing on the Madison River is some form of right of passage, and success is more likely guaranteed when time has been spent learning the dynamic and swift rhythms of the river.

The Bighorn River in Montana is a veritable trout fishing haven. With epic numbers of fish per mile, fly fishing is unsurprisingly one of the biggest attractions of this river. This is still the case even though environmental factors have impacted the fish to some degree over recent years, and the Bighorn River is considered a worthy stop-off point for any Montana fly fishing venture.

The arduous and plentiful wild rainbow and brown trout that swim in the Bighorn River make it something of a world-class fishing option for anglers across the world.

3. Yellowstone River

The Yellowstone River will always be a special place when it comes to the idea of trout fishing in Montana, and many consider it simply the best river in the state for fly fishing. This may have something to do with the fact that the Yellowstone River is the longest undammed stretch of water in the entire state, with a distinct feel of the wild and free to it.

There are large numbers of cutthroat trout to be found upstream of Livingston, and wild rainbow and brown trout populate the entire stretch of the river. Fly Fishing on the Yellowstone River is undoubtedly some of the best dry fly trout fishing anywhere in Montana, and some of the largest brown trout that get caught in the state come out of the Yellowstone River. If you could only pick one river to fish on a trip to Montana this would probably be one of the best options.

4. Gallatin River

The Gallatin River is definitely a much shorter option than any other river in Montana, but it is very easy to access as it is close to a highway. This makes it a popular option for anyone wanting to avoid hiring a guide who prefers to test out their skills on their own.

The river also still manages to provide nothing short of excellent trout fishing, and this spot is actually ideal for anglers who prefer to wade as it is virtually devoid of rafts and boats.

5. Clark Fork River

The Clark Fork is sometimes confused with the Clarks Fork of the Yellowstone River, but this particular stretch of water in Montana begins as Silver Bow Creek and in some regions merges with waters from a few other rivers renowned for trout, namely the Blackfoot, Rock Creek and the Bitterroot.

The Clark Fork has suffered its fair share of setbacks by way of nearby mining and floods, but today it is one of the well-stocked trout rivers in Montana, with some monster wild rainbows that apparently don’t give up too easily once hooked.

6. Smith River

The Smith River is considered something of a national treasure by many local anglers, although it is often overlooked by visitors. This could be due to the one public put-in and one public take-out along the whole stretch of water, which adds up to around 60 miles in total length.

You’ll find plenty of blue-ribbon trout in one of the most unique and scenic trout fishing experiences in the state, and the river benefits from having a protected status and a permit system. The wildness of the Smith remains well-preserved in no small part due to these restrictions, and rightly so as the U.S. Conservation Organization listed it as one of America’s 10 most endangered rivers back in 2016.

7. The Missouri River

The Missouri River presents, for many, the absolute finest trout fishing stretch in Montana, in no small part due to its sheer size it. The river is also accessible for fishing year-round, unlike many others in the state, although the months between April and October are considered to be the most productive by local experts.

There are reportedly consistent averages of 5000 or more trout per mile in this Montana River, which many visiting anglers have to see to believe. Many local anglers claim there is nowhere else in the state of Montana so versatile and dynamic for trout fishing that offers such great opportunities all throughout the season.

8. South Fork of the Flathead River

If you fancy the idea of a remote adventure and wild, native trout, the South Fork of the Flathead in northwestern Montana could be for you. This is one of the more remote rivers and is surrounded by the Bob Marshall Wilderness. The river can only be accessed by a Forest Service dirt track along the lower quarter, while its upper reaches are only reachable on foot.

The South Fork is a wild, west slope, cutthroat fishery, and is unique in that it is one of the only stretches of water in Montana where you can specifically find bull trout.

9. The Blackfoot River

The Blackfoot River has been the backdrop for various books and movies, as well as the lives of anglers seeking out idyllic freestone trout streams. The clear waters are a haven for the region’s native Cutthroat Trout, and the picturesque scenery alone makes for a worthwhile day spent fly fishing on the river.

The Blackfoot River’s upper reaches flow all the way down to its confluence with the Clark Fork River, and anglers are able to find great fly fishing opportunities along the whole stretch, making it a worthy addition to any Montana anglers’ stop-off points.

10. Big Hole River

The Big Hole River has often been described as one of the most scenic stretches of river in Montana. It’s not hard to see why exactly when you consider its gentle banks and the way that they wind and flow steadily through both meadows and canyons.

There is a fairly diverse range of fishing opportunities along the river, with various breeds of fish such as Rainbow Trout, Brown Trout, and Brook Trout all being prevalent in these waters, as well as the odd Westslope Cutthroat. Another Montana River that should be on every angler’s fishing list at some point, the Big Hole River is the ideal blend of good trout fishing and picturesque scenery.
