Offered for the first time, this exceptional 45-acre Parlay Ranch estate combines luxury mountain living with unmatched privacy. A custom 2,130 sq. ft. timber-and-steel alpine home by Big Valley Construction anchors the property. Bordered by BLM land on two sides, the wildlife-rich estate offers panoramic views of the Continental Divide, Never Summer Mountains, Granby Ranch, Winter Park, and the Colorado River Valley.Situated at a commanding 8,200 feet in elevation, the property transitions from gently rolling foothills into expansive, native grass meadows perfect for horses, trail riding, and pasture use. An aspen grove surrounds the residence, interspersed with native sagebrush and tall grasses. Thoughtfully positioned on the protected north side of a prominent knoll, the home enjoys absolute privacy from the road without sacrificing its sweeping valley views. The ranch sits directly along a major elk migration corridor and physically borders public land, offering abundant wildlife watching, with frequent sightings of elk, mule deer, and native species right from the porch. Built in 2015 and meticulously maintained by its original owner, this custom residence was engineered from the ground up for maximum timber-and-steel structural integrity, thermal efficiency, and lifestyle comfort. Upper-Level Living The Great Room: The open-concept upper level showcases vaulted ceilings with exposed steel and rough-sawn wood trusses. Large southeast-facing panoramic picture windows frame uninterrupted views of the Continental Divide, Granby Ranch Ski Resort, Winter Park Ski Resort, the town of Granby, and the confluence of the Colorado and Fraser Rivers. A high-efficiency wood-burning fireplace with a secondary combustion chamber, Colorado stone surround, and timber mantle serves as the room's centerpiece. Chef's Kitchen: Designed for entertaining and showcasing beautiful views of the Never Summer Range, this culinary space features a commercial-grade BlueStar range, a solid butcher-block island with a prep sink, durable quartz countertops, a dedicated wine fridge, and a walk-in pantry with floor-to-ceiling shelving. The entire space is tied together with custom distressed maple and alder cabinetry. Primary Master Suite: A true mountain sanctuary capturing sweeping views of Parlay Ranch and the Never Summer Range, featuring premium finishes and rough-sawn hardwood flooring. The spa-like primary bathroom boasts dual vanities, an elegant accent wall of authentic antique barn wood paneling, a large soaking tub, and an expansive walk-in shower beautifully finished in rich travertine and glass, equipped with therapeutic body jets.   Lower-Level Living & High-Country Utility Heated Garage & Custom Workshop: A massive 1,230 sq. ft. heated footprint features two oversized doors, offering open room to easily park three vehicles or an extensive fleet of motorized mountain toys, with a portion of the space thoughtfully designated as a custom workshop with built-in workbenches, commercial in-floor drainage, and an extensive mechanical room footprint. The Mudroom: A spacious, highly functional transition zone featuring durable ceramic tile floors, a heavy-duty custom built-in coat and boot bench with cubbies crafted from authentic antique red and grey barnboard, a large coat closet, and a full laundry area. Custom alder wood cabinetry offers abundant storage, beautifully complemented by a deep stainless steel utility sink/wash basin. Guest Quarters: The lower level is completed by two private bedrooms and a beautifully appointed guest bathroom featuring an oversized walk-in shower finished in rich travertine and glass. Wraparound Porch: Expanding the home's functional footprint, a massive covered 1,160 sq. ft. half-wraparound porch serves as an elevated outdoor living and dining sanctuary. It is the ultimate space for hosting alfresco meals, enjoying quiet morning coffee, and fully immersing yourself in the cool, crisp summer alpine wonder, while its deep architectural overhangs provide natural shade to the lower level during the warmer months.   Advanced Engineering & Energy Efficiency Climate Control: The entire residence is heated by a premium hydronic radiant in-floor system, delivering consistent warmth throughout-from the rough-sawn hardwood floors to the durable mudroom tiling and lower-level living quarters. The home also features a whole-house air exchange system and is insulated with high-R-value closed-cell foam. Smart Maintenance: Features an oversized commercial water heater and a hot water recirculation system for instant hot water. The smart mechanicals effortlessly maintain a steady 55°F to prevent freezing when the home is unoccupied, and are designed to keep the home incredibly cool in the summer and warm in the winter with minimal utility draw. UV Protection & Window Construction: All the windows in the home are metal-clad, wood framed, dual paned windows. They are treated with a specialized ceramic film that blocks over 99% of UV and infrared radiation, protecting the custom interior woodwork and flooring from high-altitude sun exposure. Modern Connectivity: Unlike many mountain properties, the estate enjoys excellent, reliable cellular reception and high-speed internet access, offering the perfect blend of total wilderness privacy and seamless remote-work capabilities. Parlay Ranch offers unmatched access to the very best of Grand County's year-round playground. Direct Public Land Access: The western boundary of Parlay Ranch unlocks seamless entry to over 11,000 acres of public BLM land that connects directly to the Arapaho and Routt national forests. Similarly, the property shares its eastern boundary with approximately 900 acres of contiguous public BLM land, allowing you to hike, hunt, bike or snowmobile out from your backdoor. It is an exceptional setup for hunting (located in premium big game GMU 18), backcountry trail riding, and exploration. Fishing & Water: Located less than a mile from a coveted Gold Medal section of the Colorado River and just 10 miles from Lake Granby, world-class fly fishing and boating are right outside your gate. Rocky Mountain National Park, Grand Lake, Shadow Mountain Lake and the Arapaho/Roosevelt National Forests are just minutes away.

The topography provides a perfect foundation for a stable and paddocks, while the expansive adjacent BLM land serves as an extension of your own property, offering miles of private-feeling trail riding directly from your gate. Within this expansive 11,000-acre BLM landscape lies the Headwaters Trail System, featuring over 28 miles of dedicated hiking and horseback riding trails that connect directly into the vast Arapaho and Roosevelt National Forests beyond.
