*Additional living space with a 1,200 sq ft detached guest home on the property, complete with two bedrooms and two full bathrooms. 1805 River Ranch draws its name from the summer of 1805, when the Lewis & Clark Expedition worked its way up the Jefferson River corridor. In one of Lewis’s entries, he notes passing a “point of rock on the starboard side” before the party “encamped on a small island”—a quiet marker of how the ranches corridor carries the earliest chapters of the West. Today, that history is paired with a rare combination of live water, privacy, and a turnkey legacy ranch setting. Set in the lower Jefferson River Valley near Three Forks, Montana, the ranch totals approximately 194± deeded acres with about 1.5 miles of live water (roughly 0.75 mile of Jefferson River frontage and an additional 0.75 mile along a parallel side channel). That water presence—paired with productive riparian cover—creates reliable fishing, a strong waterfowl and wildlife corridor, and a sense of seclusion that is hard to replicate this close to Bozeman. A complete, controlled package: a legacy river property in two separate legal parcels, unencumbered by covenants, restrictions, or conservation easements—creating exceptional flexibility for future use and planning. High-quality, move-in-ready improvements with river frontage, a trout-stocked pond, and a riparian sanctuary with widening mountain views combine to deliver immediate enjoyment and day-one confidence. With easy access to Three Forks, Bozeman, and nearby amenities, the property balances seclusion with convenience. Whether envisioned as a private retreat, equestrian base, or multi-generational holding, it offers enduring value in one of Southwest Montana’s most historically rich and naturally compelling river valleys available today on the market now.
