Boulder River Montana

Boulder River Montana Fishing


The Boulder River Montana flows approximately 60 miles from its origination in the Absaroka Mountain Range to Big Timber Montana, where it joins the Yellowstone River. As its name would suggest, the Boulder River is replete with massive boulders which create excellent fishing habitat.



The Boulder River Montana is located South of Big Timber and great fishing spots start only 5 minutes out of town, approximately a 30 minute drive from Montana Cabin Rentals. If you decide to spend a day on the Boulder River, be sure to check out the impressive Natural Bridge, approximately 20 miles outside of Big Timber along the Boulder River.

The Boulder River Montana is not as heavily fished as the Yellowstone River, and is a much smaller and calmer river to fish. Whereas most people who fish the Yellowstone River near Big Timber may rent a raft because of its width and depth, the Boulder is generally fished by walking and wading. The lies created by the boulders and the winding cut-away banks along the Boulder River Montana create excellent fishing habitat.


During the summer months, I like to use a greenish or yellowish dry fly like a caddis or hopper pattern, or just a general attractor pattern. Follow that up with a small nymph like a Prince Nymph or a Copper John about 18 inches behing the dry fly and you'll be in business.  My personal best is 17 fish in just under 90 minutes!


We, of course, always recommend that you access a Boulder River fishing report before you cast a line. One great place to access a Boulder River fishing report is from Montana Angler: Boulder River Fishing Report.

You do have to be careful along the Boulder River not to trespass, because it is surrounded by a lot of private land. But there are plenty of public fishing accesses as well.


Generally your trout will be smaller in the Boulder River Montana, particularly the farther away you get from the Yellowstone River. This is a trade-off, however, because you will generally catch more fish the further away from the Yellowstone River you get.


Montana Cabin Rentals is located within an easy 30 minute drive of the Boulder River Montana. There is truly nothing this writer loves more than spending a day on the water, and then coming home to a luxury cabin deep in the Crazy Mountains and far away from civilization. Add to that a cool beer while I watch the sun go down in absolute silence and solitude or a hot cup of coffee while I watch the sun come up, and you have yourself a recipe for the perfect Montana vacation.  We hope you'll stay with us at Montana Cabin Rentals and take advantage of the fabulous fishing at the Boulder River Montana and, of course, on your own private 160 acre stream front retreat on Big Timber Creek.
