The Fly Side of the Dam Duplex is located in the small fishing village of Fort Smith, Montana. Come see what's rising on the Bighorn River, a world class trout fishery! We are located minutes from the After bay access boat ramp, gateway to the Big Horn. If you are not into ripping lips, take a cruise up to OK-A-BEH Marina for a lake cruise or a dip in the swimming area. The beautiful Bighorn Canyon National Recreation Area has something for everyone!
