Montana Fly Fishing

Experience some of the best trout fishing in Montana on our premier Fishing Pack Trips in the Bob Marshall Wilderness.

The Bob Marshall has hundreds of miles of rivers and streams, but the South Fork of the Flathead River, one of Montana’s best kept secrets, is a fly fishing paradise with mile after mile of exciting, unforgettable water.

You can expect to catch between 20 to 40 Native West Slope Cutthroat a day, anywhere between 12 and 18 inches, with an occasional lunker over 20 inches.

The South Fork of the Flathead River is also one of the few areas in the lower 48 states that allows you to target and catch the Native Bull Trout. Bull Trout in excess of 28” can be caught and are often times considered a “bucket list” fish for many fly fishermen. Many of the drainages that empty into the South Fork of the Flathead River get very little pressure year after year and give our guests the opportunity to fish in a true wilderness setting.

Prepare yourself to leave behind the pressures of daily life and enjoy the quiet beauty of the Bob Marshall Wilderness.

During your trip you will enjoy some of the most spectacular trout fishing in America with a backdrop that is often times only dreamt of. We will move camp every couple of days during your trip, so you can fish various areas or drainages during the course of your fishing adventure. If you want to combine some still water fishing into your trip, we also can take you to some mountain lakes to mix it up a bit.  

In the spirit of conservation, Big Salmon Outfitters recommends only de-barbed hooks, and maintains a strict catch and release policy. These trips are customizable for overall duration of the trip, days/miles spent riding and how many different creeks or bodies of water we fish. Contact us to let us know what you are looking for and we will give you the best options to customize the trip you have in mind.
