These 589± acres feature exceptional improvements, seclusion, wildlife, scenery, extensive BLM boundary, productive cattle operations, and over a mile of both banks of the Big Lost River. Located 35± miles from Sun Valley over Trail Creek Pass and 20± northwest of Mackay. Large ranch holdings in the upper Lost River Valley rarely come for sale. The 589± acre Big Lost River Ranch is one of central Idaho's premier lifestyle, recreational, and ranching properties. Located in the upper Lost River Valley, 35± miles northeast of Ketchum/Sun Valley and 20± miles northwest of Mackay, the ranch is nearly surrounded by federal lands managed by the Bureau of Land Management (BLM) and encompasses over a mile of frontage on both banks of the Big Lost River, offering outstanding trout fishing.
Set up for year-round living, the ranch features a beautifully crafted and appointed owner's residence with two bedrooms and two and a half bathrooms. Designed with entertaining in mind, the owner's cabin is warm and inviting and highlighted by floor-to-ceiling windows that frame extraordinary views of Idaho's highest peaks. Additional building improvements include a wonderfully restored log guest cabin with a sleeping loft, a greenhouse adjacent to the owner's residence, a restored log tack shed, a horse barn, a calving shed, a shop building with adjoining equipment storage, and a set of working corrals with a scale house and cattle scale.
Originally run by the owners themselves as a year-round cow-calf operation producing high-quality branded beef, the ranch is currently leased for seasonal grazing to a local cattle rancher who emphasizes regenerative management practices. The property holds multiple irrigation rights covering up to 345 acres. The ranch's lush bottomland meadows are flood irrigated through a series of ditches, while approximately 130 acres are irrigated by a center pivot.
The ranch is a sanctuary for elk, moose, mule deer, whitetail deer, and other wildlife that utilize the Big Lost River corridor. With high-quality public lands in every direction, the ranch is an excellent base from which to explore the area's remarkable high country, with hiking, horseback riding, and ATV touring available right from the gate. In addition, the Sawtooth National Recreation Area, the Salmon River, and multiple federal wilderness areas are all within easy reach.
