Welcome to the Stonefly Inn & Outfitters, Montana's "Last Best Fly Fishing Lodge", located in the heart of Montana's Blue Ribbon Trout Country.

The Stonefly Inn and Outfitters is a privately owned Fly Fishing Lodge in rural Montana. No stop lights or tourist traps here – just countless miles of Blue Ribbon Trout Water, an overwhelming number of Trout and the occasional cattle drive. Based in Twin Bridges, we are licensed outfitters on the Big Hole, The Beaverhead, The Madison, The Jefferson, the Missouri and the Ruby Rivers. That's right - there is over three hundred miles of world class Montana fly fishing water within an hour’s drive of your cabin door. Because of our location, we often do not see the fishing pressure some of the other areas of the state have to deal with. In Twin Bridges, you can truly unwind and enjoy your Montana Fly Fishing Vacation along with the solitude and vastness of Southwest Montana. The days are longer, the fish are bigger and the beer is colder.

Here at The Stonefly, Dan “Rooster” Leavens and his entire staff of Montana Fly Fishing Guides are dedicated to providing you a Montana Fly Fishing Vacation that will leave you wanting to return year after year. Our average return ratio hovers around 95% season after season and Rooster goes out of his way to keep it that way. You can read some first-hand testimonials from industry leaders here.

A typical day at The Stonefly will start with breakfast with your Montana Fly fishing Guide before you head to one of our local rivers to fish. During the day, you can expect professional instruction while you employ seemingly endless techniques to catch fish. With so many rivers to pick from, each day is certain to be different. Returning to the lodge, you’ll find fresh appetizers in the Roost Lounge and take a little time to unwind and tell a fish story or two over a cocktail. Dinners are prepared nightly by our in house chef. Following dinner, nightly campfires are the norm complete with after dinner cocktails, joke telling, guitar picking and plenty of storytelling.

During your Montana Fly Fishing Vacation, you will always feel welcome at The Stonefly. You can count on professional instruction from your Montana Fly Fishing Guides, top shelf “Farm to Table” meals and courteous service from our staff. You have our word on it. Odds are, you’ll catch a few great fish while you are here as well!

The Stonefly Inn is unique in every sense. It's the perfect home away from home for flyfishermen.

Whether you are our guest for one night or five, comfortable cabins, clean sheets, warm showers and a family down home Montana atmosphere await you. During your stay in Twin Bridges, The Stonefly Inn will be your home away from home. Other amenities include complimentary wi-fi internet, satellite television and a fishermen's breakfast served each morning. After a long day of fly fishing, you're invited to unwind, maybe tell a tall tale or two and get to know other Stonefly Inn guests at the Stonefly "Roost" Lounge. Our outfitted guests can also enjoy nightly dinners from the grill. Montana beef and Alaskan salmon are just the tip of the iceberg - often times prepared by none other than the Rooster himself!

Outfitters Trip Planner

Not unlike any fishing destination, getting to Montana can require some homework before you leave for your trip. Before you string up your rod streamside, there are several things to consider ~ flight reservations, gear requirements, weather, river conditions, and car rentals.

We have put together this Outfitters Trip Planner to assist you with your planning. Starting from the top, we hope this will take some of the frustration out of dealing with your travel arrangements. This document is downloadable, and has contact information for Rooster, Holly and the rest of the Stonefly Staff.

Welcome to the roost

THe best dining in twin bridges

  When you return to the Stonefly after a day of fishing - you can look forward to appetizers and refreshments in the spacious screened in patio of "The Roost". Our guest lounge comfortably seats up to 20 guests, and is often the hub of information each night. Our "Farm to Table" meals are prepared by Fiona Oneil, our chef and range from Montana beef to Alaskan Salmon. Late night "seminars" are quite common, as our guides tend to migrate to the Roost just about the time dinner is served. One word of caution, when the liars dice gets started you might want to head for the barn!
