10,282 Acres in De Beque, CO - $14,490,000

Island Mountain Ranch encompasses approximately 10,282 contiguous acres of mountain terrain in Garfield County, Colorado, within Game Management Unit (GMU) 31. This expansive property offers diverse wildlife habitat, improved water systems, and exceptional hunting opportunities for elk, mule deer, bear, and upland game. Located minutes from De Beque, Rifle, and Grand Junction, the ranch combines seclusion, accessibility, and functionality for recreation and wildlife management.

The property features varied elevations, ranging from deep canyons and oak-covered slopes to wide mesa tops that provide excellent vantage points and feeding areas. Steep cliffs surrounding much of the ranch create a natural barrier that limits access, allowing game animals to use the land as a secure sanctuary. Island Mountain Ranch is bordered by the historic High Lonesome Ranch and tens of thousands of acres of Bureau of Land Management (BLM) ground—much of which is extremely difficult to access—further enhancing privacy and wildlife use. Panoramic views stretch across the western ranges, Castle Rock, Mount Blaine, and the Grand Mesa, adding to the property’s dramatic setting.

Located within Colorado’s GMU 31, the ranch is known for exceptional elk and mule deer genetics. It qualifies for the Colorado Landowner Preference Program and has historically received two or more mule deer vouchers per year. Hunters benefit from over-the-counter elk tags for 2nd and 3rd rifle seasons, as well as resident archery. Elk are frequently observed in the 360–380" class, with some bulls approaching or exceeding 400". Mule deer have historically scored in the 180–190" range, with multiple deer harvested above 200"; the largest approaching 240". Rugged terrain, surrounding private land, and nearly inaccessible public lands create minimal disturbance, allowing wildlife to thrive. Hundreds of recent trail-camera photos from 2025 highlight the ranch’s remarkable trophy potential.

Habitat improvement has been a major focus across the ranch. The property includes live, improved springs, four drinkers with catchment systems, and strategically cleared openings to increase grass growth and create additional feeding areas. Several food plots enhance forage diversity. An extensive interior road and trail network provides efficient access while minimizing disturbance to prime habitat zones. Access may be limited during heavy snow, though wildlife remains present year-round due to the favorable combination of elevation, feed, and cover.

A historic wildfire rejuvenated vegetation, resulting in dense oak brush and native grasses that now provide excellent bedding and browse. In October 2025, more than 110 bull elk were counted on the property, using the mesa as a resting and feeding area after the rut. Regrowth, paired with consistent water availability, has transformed the ranch into a productive and self-sustaining habitat system for wildlife and livestock.

Improvements include a recently constructed one-bedroom, one-bathroom off-grid cabin built in 2025 along Kimball Creek. The permitted cabin operates with generator power, a septic system, and a cistern water supply, offering functional lodging for hunting seasons or short stays. Its placement near the main access road minimizes disruption to the upper ranch, which remains a largely undisturbed wildlife sanctuary. Multiple elevated Banks Blinds are strategically positioned across the property for safe and effective hunting or wildlife observation.

Access to the ranch is via a well-maintained county road leading to a single gated private roadway that climbs to the upper mountain. This secure access ensures privacy while providing year-round usability for owners or managers. Despite its size, world-class wildlife, and thoughtful improvements, the ranch is offered at an exceptional price per acre—one of the best large-scale land values in western Colorado. Visitors consistently remark that nothing else compares: a rare blend of scenery, seclusion, and trophy-quality game that must be experienced to be fully appreciated.

Nearest towns include De Beque (approx. 20 miles), Rifle (approx. 35 miles), and Grand Junction (approx. 40 miles), each offering amenities, supplies, and commercial airports. Island Mountain Ranch represents a rare opportunity to own one of western Colorado’s premier big-game properties—where scale, genetics, and solitude come together in a setting that cannot be replicated. Properties of this size, quality, and accessibility seldom reach the market, making this a truly exceptional legacy offering.
