Boulder River Outpost

Location, location, location! The all inclusive Boulder River Outpost places you in in the heart of one of the most spectacular valleys in all of Montana. The Boulder river slices through Montana's highest mountains with the Beartooths to the east and the Absarokas to the west. Our Boulder River Outpost is located on the banks of the East Boulder river and just a 1/2 mile from the main Boulder and twenty miles from the Yellowstone. 

We have a huge variety of lightly fished waters at our fingertips including access to private ranches, strictly permitted rivers and technical spring creeks. The dry fly opportunities in the Boulder Valley and its surrounding waters are some of the best in the state! After a great day of fishing come back to our rustic and comfortable cabins and enjoy a delicious meal prepared by our camp cook. If you haven't had enough you can grab a rod for a few more casts on the East Boulder or enjoy the sweeping views of the ranch country where Robert Redford's "The Horse Whisperer" was filmed.  The Outpost is the ultimate location for small groups that want a lot of fishing variety with a unique lodging experience.

We fish a giant swath of Montana and our guides feel that the diverse fishing opportunities from the Boulder River Outpost offers some of the best variety from one location of any region in the state. Most of the waters that we target are also very lightly fished, either because most guides can't row the technical water on the Boulder with drift boats (we use both rafts and drift boats), or because they can't access the National Forest waters, or because they don't have access to the private ranches in the region that we have exclusive access to. Dry fly fishing is often spectacular and most of the summer we fish almost exclusively on the surface.

Boulder River
Below the 300 foot water fall at the Natural Bridge the Boulder enters big ranch country but doesn't lose its fast pocket water nature. Browns and rainbows dominate here and dry fly fishing remains our favorite technique. Larger trout in the 16-18" range are common and fish over 20" are regularly caught on the lower floats near the Yellowstone. This water is often floated in the summer using our skilled guides and customized rafts with fishing frames, seats and anchor systems. 

West Boulder River
This medium sized river has a mixed bag of mostly rainbows and cutthroats - some of which are very big. The valley is gorgeous. We also offer trips into the remote wilderness area at the headwaters either by hiking or by horse back. An overnight extension to the West Boulder tent camp in the backcountry is also an option.

East Boulder River
The East Boulder is smaller than the West Boulder. The trout aren't as big but the action can be great and as a bonus it flows right along the edge of the Outpost providing for some great evening fishing after dinner. 

Yellowstone River
This legendary river is best floated. It provides outstanding fishing from its headwaters in Yellowstone Park all the way to beyond Columbus. From our Boulder River Outpost we focus on the "Lower Yellowstone" from Livingston to Columbus where huge browns and big rainbows wait. A variety of hatches come off in the spring and early summer followed by outstanding terrestrial fishing with hoppers, ants and beetles in the late summer and early fall. Late season produces some huge pre-spawn brown trout on streamers and big nymphs.

Stillwater River
The stillwater is the sister river of the main boulder and is found one river valley to the east. It is slightly larger in volume but offers similar fast action pocket water with great dry fly fishing. It is a long drive from the major guide centers of Bozeman and Livingston which helps keep it off the radar of many of the areas guides. At higher flows we float the Stillwater in rafts and at lower flows it is best wade fished.

Musselshell River
We have access to a great small stream fishery on a private ranch on the North Fork of the Musselshell. The stream is rested several days each week and never fished two days in a row. Enjoy one undercut bank after another, each with eager trout that rarely see flies. This is a great place to attempt a Montana grand slam since all four species of trout can be found: cutthroat, brown, rainbow and brook trout. 

Sweet Grass Creek
Another fantastic small stream that drains the rugged Crazy Mountains. This is just 45 minutes from the Outpost and we fish private water on a 25,000 acre ranch. The sweeping views are breathtaking if you can take your eyes away from the creek and its aggressive trout.

Burns Lake
Burns lake is on another private ranch and offers the chance for trophy trout on both dries and nymphs. The lake is amazingly productive with great hatches of callibaetis mayflies and damselflies. Fish up to 10 lbs swim in its depths.

Livingston Spring Creeks
For anglers that wan't to test their skill on some of the most prolific and technical waters in the world we can visit the famous spring creeks near Livingston (about an hour drive) including DePuy, Nelson and Armstrong. These wade fishing streams are born from underground springs and are infested with aquatic insects and other macroinvertebrates that result in an amazing density of trout. Hatches on the creeks are spectacular but expect to work hard to fool the often highly selective trout.


The Boulder River Outpost sits on the edge of several massive ranches where Robert Redford's "The Horse Whisperer" was filmed. There are two cabins and a game room. The smaller bunkhouse cabin has three bedrooms (bedroom 1 - single queen; bedroom 2 - double XL twins; bedroom 3 - single XL twin), a living area, full kitchen and single bath. The larger main cabin has two bedrooms (bedroom 1 - queen + XL twin; bedroom 2 - double XL twin or convert to king) and two bathrooms as well as a larger kitchen, mudroom and wader room. Each cabin has a wood stove and wood accents. The Outpost can accommodate up to 8 anglers and we can offer the entire facility as an exclusive for your party with at least 3 anglers at no added cost. The minimum group size is 2 and maximum is 8. Our guides and lodge chef also stay at the Outpost to prepare all meals, tell stories and engage our guests in some lively lawn games after a day on the water. The East Boulder River flows along the property boundary and offers some great wade fishing and the main Boulder is just 1/2 mile down the gravel road.

Our lodge chef and guides work hard to ensure that you will enjoy outstanding dining while at the Boulder River Outpost. We prepare hearty breakfasts each morning that may include blueberry pancakes, bacon, omelettes, hot coffee, OJ, and fresh fruits. Lunches are generally picnic style along the river but we sometimes return to the cabins to grill brats or chicken to break up our day on the water. Dinners are a multi course event that begin with a generous supply of appetizers while our guests enjoy some of the locally brewed beers we provide or a refreshing glass of wine. Entrees are often grilled on the outdoor grill and desserts are always home made. We frequently put to use cast iron Dutch ovens over hot coals to prepare succulent side dishes or tasty desserts.
