Some opportunities simply cannot be recreated, and a rare few landscapes become part of a family's story for generations. In a region where large acreages are increasingly fragmented and developed, this extraordinary 65-acre property offers the rare chance to own and steward a remarkable piece of Boulder County's rural landscape. Protected by a conservation easement that helps preserve the area's agricultural heritage and open spaces, the property offers a lasting connection to the land and the opportunity to become part of its future. Situated between Boulder and Lyons at the doorstep of the Colorado foothills, the property is defined not by a single purpose, but by the freedom to create one of your own. Envision a private equestrian retreat, a multigenerational estate, a specialty agricultural venture, or a sanctuary where open skies, quiet surroundings, and the luxury of space become part of everyday life. The land is thoughtfully improved with 29 irrigation water shares, an irrigation pond, corrals, a climate-controlled 30' x 100' greenhouse, and hundreds of trees planted throughout swaled portions of the property. A cozy and inviting two-bedroom, two-bath home offers immediate comfort, while existing infrastructure, including a septic system designed for an additional four-bedroom home, provides exceptional future potential. Large acreages of this scale, with this level of infrastructure and such close proximity to Boulder, Longmont, and Lyons-the gateway to Estes Park and Rocky Mountain National Park-are becoming increasingly uncommon. This is more than a home or a ranch. It is an opportunity to create a legacy and preserve a way of life that is becoming increasingly rare in the Colorado landscape. The luxury here is not simply found in the land itself, but in the possibilities it holds-the freedom to build a life connected to the land and create a place that can be cherished and passed from one generation to the next.
