An extraordinary NEW PRICE. An extraordinary OPPORTUNITY. It's hard enough to find 65 acres in Boulder County-let alone at this price. In a region where large parcels continue to be divided and developed, this remarkable property offers a rare chance to own a significant piece of Boulder County's rural landscape. Situated between Boulder and Lyons at the doorstep of the Colorado foothills, the property offers an exceptional combination of significant acreage, irrigation water, agricultural infrastructure, and an unbeatable location. Protected by a Boulder County conservation easement that preserves the area's agricultural heritage and open spaces, the property offers lasting privacy while ensuring the surrounding landscape retains its rural character for generations to come. Whether your vision includes a private equestrian retreat, a multigenerational estate, a specialty agricultural venture, or simply the luxury of open skies, quiet surroundings, and room to breathe, this property offers the freedom to create a lifestyle uniquely your own. 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 the swaled portions of the property. A welcoming two-bedroom, two-bath home provides immediate comfort, while existing infrastructure, including a septic system designed for an additional four-bedroom residence, creates exceptional flexibility for the future. Large acreages with established agricultural infrastructure, irrigation water, and close proximity to Boulder, Longmont, Lyons, Estes Park, and Rocky Mountain National Park are becoming increasingly difficult to find-especially at this price. More than a home or a ranch, this is an opportunity to invest in a lasting legacy and enjoy a way of life that is becoming increasingly rare in Boulder County.
