When it comes to trout fishing, there really is no place like Montana. Home to some of the most famous rivers in the world, the fly fishing options in the state are endless. With everything from gin clear high mountain lakes, to tight quartered technical tributaries, Montana offers everything one could want as a trout fisherman. So follow along and see exactly what it is that makes big sky country so darn special.

Rivers to Fish in Montana

Bitterroot River

While Montana is home to several world-renowned trout rivers, there are five rivers in particular that we feel truly encompass Montana trout fishing. The first of the five is the Bitterroot River (pictured above). Nestled just outside of Missoula, Montana, this blue-ribbon trout river flows for 84-miles through the Bitterroot Valley and contains some of the most incredible scenery that MT has to offer. The Root is home to rainbows, browns, brookies, bulls, and last but certainly not least, native westslope cutthroat. While the fishing on the Root is second to none, the views and wildlife are no exception. The Bitterroot Valley inhabits a healthy population of bald eagles, mule dear, and the occasional bugling elk.

Blackfoot River

Next, we have the Blackfoot River. As one of the most storied rivers in all of Montana, the Blackfoot is the proud birthplace of Norman Mcleans, A River Runs Through it. Although the movie itself was actually shot on the Gallatin, Yellowstone, and Boulder Rivers, Mclean wanted both the book and film to be set just outside of Missoula, and for good reason. This river is teeming with mountain views, Ponderosa pines, and a healthy population of trout. The Blackfoot provides anglers with a very diverse fishing experience. With everything from deep, slow-moving pools to shallow, choppy riffles, many anglers find themselves fishing dries, nymphs, and streamers all within the same day!

Missouri River

When it comes to targeting big, predatory fish, the Missouri River is a must. Boasting an average fish length of 17 inches, you won’t want to leave home without the strong stuff. We highly recommend having a 6-7 weight rod in the boat….let’s just say things can get serious real quick. Flowing for over 2,500 miles, the Mo is the longest river in the United States! While many anglers prefer to fish from a drift boat, there are numerous public access sites for wade fishermen. We highly recommend parking at Sterling Ranch near Craig, MT for ease of access and practical wading. Rental boats are also a great option for out of town anglers looking to cover water quickly.

Madison River

Madison River 

The Madison River is one of the most revered bodies of water in all of Montana. This 183-mile tributary forms at the heart of Yellowstone National Park and flows several hundred miles north until it eventually merges with the Missouri. The Madison typically fishes best during early summer and all through the fall, but that doesn’t mean you can’t get on ’em any time of the year! However, during the mid-summer months the park is very quick to close fishing due to higher than normal water temps, so plan accordingly. When wading the Madison, it is crucial to do so cautiously. There are several stretches that appear to be shallow but are much deeper than expected. The river is lined with lush, tall grassy banks which make for excellent hopper fishing when the weather allows. Be sure to check the Yellowstone fishing regulations before planning your trip to the Madison!


South Fork of the Flathead River

Finally, we have the south fork of the Flathead River. Flowing for nearly 98-miles, this river serves as the second-largest tributary of the Flathead River and is acclaimed as one of the most pristine rivers in the state of Montana. The river originates in the Bob Marshall Wilderness, and flows north until met by Hungry Horse Reservoir. The Bob is referred to as one of the most remote areas in the lower 48, and we intend to keep it that way. The south fork of the Flathead is home to genetically pure, westslope cutthroat trout. The same ones discovered by Lewis and Clark in the 1800s. Wading access is readily available on the south fork, and is preferred by many that are camping on foot. However, for boat access, anglers typically book trips with local outfitters in which they pack in on horses and float/fish their way out. When visiting the Bob it is crucial to plan ahead. Forgetting the necessities can quite literally be the difference between life and death, so come prepared.

*Note: Bear spray should be kept on hand when visiting any one of these rivers, but especially on the south fork of the Flathead.

Creeks and Streams to Fish in Montana 

While Montana certainly has its fair share of trout rivers, their are still plenty of small water options where productive fishing can be had. Compared to larger rivers, the trout inhabiting smaller streams tend to be smaller in size but are often caught in greater numbers due to their opportunistic feeding habits. Smaller streams are typically sparse with aquatic insects, which make the trout highly alert when it comes to a meal. Below are a couple of small stream options worthy of checking out this fall!

Rock Creek

Located deep within the Lolo National Forest, Rock Creek serves as an excellent option for anglers looking to spend their day picking pockets. Rock Creek is a tributary of the Clark Fork River, and flows for 52 miles between the Sapphire and John Long Mountains. Despite its lack in size, Rock Creek holds a whopping 2,000 fish per mile and is half the size of many larger rivers in Montana! This creek has got diversity written all over it. Its waters support a healthy population of brown, brook, rainbow, cutbow, cutthroat, bull trout, and of course whitefish!

Depuy Creek

Paradise Valley is home to some of the world’s most beautiful spring creeks. Spring creeks are streams that receive a constant flow of water from an underground aquifer that supplies cold water year-round. While there are several hidden gems tucked away in the valley, Depuy Creek has been a personal favorite of Montana anglers for years in the past. While Depuy Creek is considered a small stream, it’s limestone influence produces a rich population of aquatic insects, causing trout to reach abnormally large sizes for a small/medium-sized fishery.

Nelson Creek

For anglers in search of a more challenging stream, we highly recommend Nelson Creek. Not only is Nelson’s the smallest spring creek in the paradise valley, but it is also the most challenging. The creek predominantly consists of crystal clear flats, presenting a host of challenges when attempting to sneak up on active fish. While long leaders and light tippets are a must on this creek, they only make the fight more interesting when a fish takes your fly!

Montana High Alpine Lakes

For the adventurous angler, high alpine lakes are a golden opportunity to escape the crowds and target some truly undisturbed fish. While alpine lakes often require lengthy hikes into the backcountry, it is because of these treks that many opt for easier fishing options.  Stillwater fishing can be very tough, but can also be some of the most rewarding and exciting fishing out of the entire year. Whether you’re fishing dries, streamers, or nymphs, seeing a fish eat in crystal clear water is an experience that never gets old. High alpine fishing is all about preparation. Often times it can take the better part of a day just to hike to the lake, so be sure to bring the necessities. There are various ways to fish alpine lakes, with sight fishing typically being the most rewarding. Stalking the banks for cruising fish is a great way to keep the fishing fun and unpredictable. However, stay far off the bank as not to cast a shadow, and spook fish that are on the move.  Click here to find some alpine lakes of your own!
