A once-in-a-lifetime chance to own a piece of the legendary Old West. For the first time in nearly 150 years, Hogan Ranch-a 450-acre stretch of wild Colorado wilderness-opens its gates to private ownership. Three exceptional 35-acre parcels - are now available, offering a rare opportunity to stake your claim where the rugged spirit of the West still thrives. Accessed via a private road from Hwy 93, the Legacy Estates at Hogan Ranch are bordered on three sides by City of Boulder Open Space, ensuring perpetual privacy and protection from development. Direct access to nearby trailheads connects residents to miles of hiking and riding paths into the iconic Flatiron foothills. Coal Creek Reserve (Lot 2) sits atop a broad, west-facing plateau with sweeping 180-degree views of the Flatirons, Coal Creek Canyon, and untouched Jefferson County ridge lines. A 3-acre buildable envelope overlooks the lush, wildlife-rich Coal Creek corridor, offering complete seclusion-hidden from roads and neighbors. Here, abundant wildlife roam freely in a landscape that transforms beautifully with the seasons. Within the envelope, owners may build a single-family residence and two accessory structures such as a detached garage, greenhouse, barn, or corral. Recreational amenities-a pool with cabanas, tennis or basketball court-are also permitted. The residence may include a separate apartment Accessory Dwelling Unit (ADU) as part of the residential structure; not a separate structure, for use by a caretaker or family member. Accessory structures may not exceed a combined 6,000 square feet. There is no limitation on the size of the primary residence. All structures are restricted to a maximum roof height of thirty (30) feet. Owners can design expansive living spaces with soaring ceilings, walk-out basements, and architecture that frames the panoramic views. Owned by the same family since 1876, Hogan Ranch embodies history, solitude, and unspoiled beauty-more than land, it is a legacy.
