Hidden among pine forest, mountain meadows and granite outcroppings above Boulder, Whisper Mountain Ranch is one of the Front Range's rare private mountain estates: 108 acres at 8,500 ft, just 25 minutes from Boulder. The approach winds through tall pines and open meadow toward snow-capped peaks, a setting closer to the great family retreats of the Alps than to modern Colorado. Private trails lead deep into the forest, and wildlife moves freely across the land. At the heart of the ranch, a 10,175 sq ft timber-frame residence built by Harrington Construction, with 6 bedrooms and 7 baths, rises naturally from its surroundings. Walls of glass frame a panorama that shifts through the day, from sunrise on distant summits to alpenglow at dusk and star-filled nights. Under current county regulations, a home of this size could no longer be built here today, so this one simply cannot be replicated. No conservation easements encumber the 3 individually deeded lots, so the new owner keeps full flexibility to use and improve the land within county rules, a rare freedom at this scale. The land invites you outside in every season. A horse barn and meadows for grazing, a greenhouse, lush forests, private hiking trails, and dramatic rock formations offer endless ways to enjoy a true mountain lifestyle. In winter, Eldora ski resort is just 20 minutes away, including the children's ski program Eldorables, the expert alpine terrain of the Corona Bowl, and machine-groomed cross-country trails at its base. Historic Gold Hill is close by, yet the ranch feels a continent away. Whisper Mountain Ranch can be many things: a full-time mountain residence, a gathering place for family and friends, a quiet creative retreat, or a legacy property to be passed down for generations. Also available separately: an adjoining 36-acre parcel at 11320 Gold Hill Rd, offered with a set of fully approved construction plans, an opportunity to expand the estate or create a second residence nearby.
