Montana Fishing Trips

Wilderness Fly Fishing

The Bob Marshall Wilderness presents exceptional Montana fly fishing opportunities for fishermen of any skill level. Many of our young guests get their first taste of a life-long passion fly fishing with their fathers on the Sun River.  For accomplished and well-traveled fishermen, these remote mountain streams offer an unparalleled trout fishing experience.

The fish move up and down the rivers and streams in cadence with water temperatures and flows.  There are no barriers to their movement, so they tend to optimize their comfort and feeding habits largely in tune with the rivers and streams.  We have a pretty good idea where they'll be most prevalent based on the time of year, and what their habits are at that time.  We also know from experience the best lures and flies for the time of year.

A typical morning begins with a hearty breakfast in camp, and depending on how close we are to the river, we either walk or ride horses to our destination. Out here, you can fish upstream, downstream, ripples, holes, or whatever your prefer. The fish are everywhere and will be active at different times of day depending on air temperature, light or shadows on the water, terrestrial insect activity among other factors.  This makes for quite a variety in activity at different times of day and in different stretches of the streams.

Montana Flyfishing


After a sack lunch in a shady spot along the river, you have the rest of the afternoon to continue fishing with almost no one else on the water with you.  You will occasionally see deer, elk, an assortment of birds of prey, and perhaps even a bobcat along the river, but you rarely see any other person, unless it's your fishing buddy with you.  After getting back to camp and the often well deserved happy hour, a filling and  delicious back country dinner is served in the early evening. 

The day is capped with camaraderie, stories, and general good fellowship around the campfire. Some guests like to keep fishing until dark, which can be pretty late in Montana's northern latitude.  Often, we find that people want to stay up extra-late one clear evening to see the vast Montana evening sky.  It mostly defies characterization due to the vastness of the stars, the depth of the Milky Way galaxy, and the absolute absence of any light pollution.  Montana is often referred to as Big Sky Country, and our night-time skies are unbelievably rich with star gazing opportunity.

Fly fishing Montana is many angler's dream, and the headwaters of the Bob Marshall readily fulfill that quest.  Rivers are lightly fished and you will not see many, if any, other fishermen on the river.  The scenery is unmatched.  When the water warms up in July and then through the end of the summer under optimal conditions we've had fishermen catch 50-70 fish a day.

Seasons and Weather

The high country summer season is pretty short by most standards.  The winter snow runoff lasts until the end of June, and the water quality stabilizes in mid-July.  Often, our snow pack lasts in the high basins well into July even as it rapidly recedes in the summer heat.  Our waters run high and murky until early July, but by mid-July they are running clean and cold.  The best fishing begins as soon as water clears.  The days are warm by then, bu the evenings and early mornings can be chilly.  You don't ever need waders for mountain fly fishing, but you will need to pick your river crossing locations a little more carefully this time of year.  Mid-July to end of August generally coneys the most consistenly good weather for us, and that is a good thing for our fishermen.  Our days gradually warm to the 70-80's as we get through the end of July and into August. 

Fly Fishing North Fork Sun River

August is the hottest month when we can get daytime temperatures in the 90's and mild evening temperatures.  We do get an occasional thunderstorm in August, but they are fast moving and infrequent.  The terrestrial insect population explodes with activity this time of year and can put the trout into feeding frenzies on sunny afternoons.  From time to time we get requests for fishing trips around Labor Day.  This is a great time to fish, as the nights are starting to cool but hte days stay agreeably warm.  This is the lowest water flow time of the year, and we seek out the headwaters where the streams are coldest and most predictable.

Flies and Lures

The mountain trout don't see many people and thus are pretty open to hitting a lot of different combinations including dry flies, dry flies and wet fly trailers, and spinning lures.  They all work pretty well.  


There are so many aspects to fishing the Bob Marshall that make your trip exceptional.  The stunning sceneray, the seclusion, the lack of competition on the water, and the quantity of trout per mile all contribute to the experience.  However, we've heard the frantic dry fly action on top of the water is what separates this fishing experience from any other anywhere.  The mountain trout are very aggressive, and strike strongly at agitators and other flies resembling terrestrials (grasshoppers, horseflies, deerflies, ants, etc).  They feed all day, hit frequently, and hard.  They hammer the dry flies, frequently breaking the surface full body, and there is nothing more exhilirating than this amount of wild action along a river, in hole after hole, all day long.



First of all, thesea are wild trout, not owning anything to anyone.  They are fantastic fighters and will make you earn every one you land.  They do not give up easiily and it's hard to imagine a more worthy fresh wter competitor!  Depending on the stretch of water and whether we're east or west of the continental divide you can catch any of these species:

  • Rainbow Trout
  • Cutthroat Trout
  • Brook Trout
  • Arcticl Grayling
  • Bull Trout
  • Mountain Whitefish

These fish live year long in hard water conditions where the rivers freeze over in the deep of winter.  They withstand the angry surge of spring snow melt, and otherwise spend their time in very cold and unforgiving water.

Friends and Families

A trip with A Lazy H as your Montana fly fishing guides has something for everyone, including the non-fishermen.  For those wishing to take a horse packing experience, you are not stuck with just being on the river.  We have innumerable options for you to take day horse rides, hikes, or just general exploration.  We've found that this flexibility for activities creates a lot of family harmony rare in a western vacation experience.
