Ironside Castle Rock Ranch

At 31,191± deeded acres spanning Malheur, Grant, and Harney Counties, with associated Bureau of Land Management (BLM) grazing allotments supporting approximately 780 cow/calf pairs seasonally, Ironside Castle Rock Ranch is a working cattle operation at genuine scale. Rising more than 4,200 vertical feet from near Beulah Reservoir to the privately owned summit of Ironside Mountain at 7,811 feet, the ranch transitions through irrigated meadows, sagebrush uplands, mountain mahogany ridges, rugged river canyons, and timbered mountain country. Towering above ranch headquarters, Castle Rock serves as an iconic landmark overlooking the heart of the ranch and the surrounding landscape.

What truly sets this ranch apart from other large Western holdings is water. The ranch encompasses approximately 25 miles of private river and stream corridor, including roughly 8 miles along the North Fork Malheur River as it flows through remote canyon country immediately below the federally designated Wild & Scenic reach. Additional stream frontage includes portions of the Little Malheur River, Lost Creek, and Bridge Creek, creating an exceptional network of riparian habitat, wildlife corridors, and recreational resources rarely found within a single ownership.

These canyon fisheries are so isolated that 18+ inch trout go largely undisturbed, with the occasional horseback rider, hiker, or kayaker among the only visitors in a given season. Combined with nearby Beulah Reservoir, the ranch offers a remarkable diversity of water resources, wildlife habitat, and backcountry recreation. An undeveloped private hot spring along the river near the reservoir further enhances the property’s appeal.

Three livable homes, working corrals, and livestock handling facilities support day-to-day ranch operations, while the scale, water resources, wildlife values, and dramatic scenery create a property of unusual character. It is increasingly rare to find a ranch capable of supporting a substantial cattle operation while also offering world-class fishing, abundant wildlife, and remote corners that remain largely undiscovered. Ironside Castle Rock Ranch represents a rare opportunity to own a truly untamed piece of the American West.
