General Description

Upper Sawmill Creek Ranch was originally homesteaded by a local settler in 1919 and represents one of only two private parcels in the Sawmill Creek Valley. The balance of the valley is in federal ownership and managed almost entirely by the Salmon-Challis National Forest. The property lies on the northeast side of Bear Mountain, a sprawling series of ridgelines and canyons that rise to almost 11,000 feet and separate Sawmill Canyon from the upper Little Lost Valley. Sawmill Canyon Road lies along the east boundary the property and continues up the canyon until culminating in a series of unimproved logging roads and mining trails. The granite peaks of the Lemhi Range lie east of the ranch and provide a spectacular backdrop. The ranch features a wonderful mix of open meadow, stands of aspen and cottonwood, and rafts of willow and river birch through which Sawmill Creek flows. The property also enjoys stands of Douglas fir that extend from Bear Mountain into the valley bottom. The ranch is perimeter fenced and suitable for pasturing horses and cattle.

Learn about the locale


Upper Sawmill Creek Ranch is located within Sawmill Canyon in central Idaho’s upper Little Lost Valley approximately two hours west of the popular resort community of Sun Valley and two hours north of the city of Idaho Falls. Friedman Memorial Airport in Hailey, 15 miles south of Sun Valley, offers regular commercial air service on Delta, United, and Alaska Airlines. Idaho Falls provides alternate commercial air service out of Idaho Falls Regional Airport on Delta and United. Vehicular access to the property is via the Little Lost Road, an all-season, gravel county road that bisects the valley, and Sawmill Canyon Road, a seasonal, secondary road that links the ranch and Sawmill Canyon with the rest of the valley. As mountain snowfall begins to accumulate late in the year, Sawmill Canyon Road closes until spring and access to the property is limited to snow machine. The town of Mackay, 40 miles west of the ranch, offers a runway capable of handling larger twin-engine aircraft, while the community of Arco, 65 miles southwest of the property, is home to a lighted runway suitable for most jet aircraft. The ranch also features its own 2,500± foot grass airstrip allowing for convenient fly-in access by small plane.


The Little Lost Valley lies in the heart of Idaho’s “big sky” country and encompasses one of the state’s most scenic areas. The massive Lemhi and Lost River Ranges – Idaho’s highest mountain chains – flank the valley and run for over 75 miles before ending near the Salmon River to the north. These two ranges boast eight of Idaho’s ten peaks over 12,000 feet, including Mt. Borah, the state’s highest at 12,662 feet, and provide spectacular views along with numerous backcountry recreation opportunities. The Little Lost River flows the length of the valley and provides irrigation water for the valley’s many farms and ranches, along with wildlife habitat and trout fishing opportunities, before disappearing into the basalt lava flows further south on the Snake River Plain. The majority of the land base in the valley is in federal and state ownership with the largest percentage of private lands situated around the small agricultural hamlet of Howe, 45 miles south of the ranch.  

The property spans Custer and Lemhi Counties, which are among Idaho’s largest counties covering an area of nearly 10,000 square miles. Despite their size, they are two of the state’s least populated counties with a combined population of around 12,500 residents. The recorded history of the area begins with fur traders and pathfinders traveling through the region as early as 1824, and prospectors and miners arriving in the 1860s and 1870s. The principle industry is cattle ranching with livestock operations often stretching back multiple generations. The mining and timber industries have also played important roles over time. More recently, tourism and outdoor recreation have emerged as important components to the local economy by capitalizing on the area’s natural beauty, diverse recreation resources, and low-key lifestyle. 


The elevation of the property is approximately 7,000 feet. Summer temperatures at this altitude are idyllic with highs reaching the 80s and then cooling to the mid-40s at night. Winters are cold with snowfall varying depending on annual moisture patterns.

Recreational Considerations

Sawmill Canyon and the upper Little Lost Valley offer a variety of high-quality recreation opportunities. Trout fishing, wingshooting, big game hunting, horseback riding, ATV riding, cycling, hiking, ski touring, and wildlife viewing can all be outstanding and enjoyed either on or minutes away from Upper Sawmill Creek Ranch.

The cold, clean waters of Sawmill Creek originate high in the mountains above the ranch and flow for approximately two miles through the property and a lush riparian corridor of aspen, willow, and Douglas fir. Sawmill Creek is home to a lively trout fishery with wild rainbow as well as an isolated population of native bull trout that thrives in the creek’s upper reaches. Perfect for fly anglers of all skill levels, Sawmill Creek is an intimate and inviting freestone stream that offers a trout-filled pool, riffle, or undercut bank around every turn. In addition, Sawmill Creek is one of the main tributaries to the Little Lost River, and expanded fishing opportunities exist a short distance from the ranch on the Little Lost as well as on other key tributaries such as Summit Creek and Wet Creek.  

An abundance of wildlife uses the surrounding mountains, foothills, forests, and grasslands throughout the year. Elk, mule deer, and antelope can be found browsing and grazing on the hillsides, while moose wander creek drainages and riparian areas. Chukar partridge are plentiful on ridgelines and rock outcroppings, and blue grouse and sage grouse utilize the area’s springs and abundant sage steppe habitat. Ducks and geese remain in the area until frozen water pushes birds further south, although numerous warm springs and spring creeks often remain open through the winter, providing year-round open water. A multitude of non-game birds and mammals are found in the valley as well. The ranch is located in Idaho hunt unit 51 and the Lemhi elk zone.
