About Us

Welcome to our shop

Welcome to The StoneFly! We are conveniently located at the crossroads of I-15 and I-90 in Butte, Montana. Montana's best little fly shop!

Nestled next to the continental divide, this is the place to come for the Montana fly fishing trip of your dreams. There are more blue ribbon fisheries nearby than any other location in the state.


The StoneFly proudly opened its doors in April of 2006. The shop is the culmination of years of hard work and dedication by partners Chris Bradley and Mike Marcum.

Our fly shop is stocked with all of the latest gear, flies, and fly tying materials to ensure your Montana experience is a memorable one. Whether you prefer fly fishing rivers, lakes, or small streams, we have what you need.


The StoneFly has a fly selection second to none. With over 1300 fly bins, we have the flies to put you onto fish. From the old standards, to innovative local patterns extensively tested on our area waters. In addition, our fly tying selection will leave the most discerning tiers satisfied.

The StoneFly is also your trusted source for guided fly fishing trips on the Big Hole, Beaverhead, Madison, Clark Fork, Missouri, and Jefferson Rivers.

Enjoy the breath-taking scenery of southwest Montana, while casting to rainbow, brown, and cutthroat trout, as well as arctic grayling. Trust our local knowledge and expertise to make this the Montana trout fishing trip of your dreams.
