Welcome to a rare legacy property along the legendary Missouri River-an extraordinary Montana retreat where luxury meets the untamed beauty of Big Sky Country. Spanning more than a mile of pristine river frontage, this remarkable estate offers a level of privacy, recreation, and natural splendor seldom found in today's market. Here, world-class fly fishing, boating, and quiet evenings along the water are simply part of daily life. Elk, deer, eagles, and other native wildlife move freely through the surrounding landscape, creating the kind of authentic Montana experience that defines premier riverfront ranch ownership. The castle-inspired residence is both striking and welcoming, designed for gathering family and friends while embracing the surrounding scenery. Inside, you'll find a cedar-lined sauna, an expansive wine cellar, multiple fireplaces, and a distinctive turret retreat ideal for a private library, reading room, or family lounge. The thoughtfully designed layout features separate wings for comfort and privacy, anchored by a grand entry and an open-concept kitchen, living, and dining space framed by sweeping river and mountain views. Outdoors, the property is designed for a true Montana lifestyle. A beautifully crafted boathouse provides effortless access to the river, while aviation enthusiasts will appreciate the airplane hangar and private airstrips-making arrival from anywhere in the West both seamless and memorable. Properties of this scale and character along the Missouri River are increasingly rare. Whether envisioned as a private family compound, a sporting retreat, or a generational ranch to steward and enjoy for decades to come, this is an opportunity to own a truly exceptional piece of Montana.
