General Description

Twin Bridges Retreat is part of a unique 1,360±-acre property known as Twin Bridges Ranch, which was purchased by Sun Valley interests in the early 1990s and divided into 12 estate parcels ranging from 40 to 300 acres. Totally insulated from the outside world, Twin Bridges Ranch is surrounded by federal lands managed by the Bureau of Land Management (BLM) and is without any public access. The individual parcels are subject to CC&Rs as well as conservation easements that prevent further subdivision of the properties. Preserving the quiet, secluded nature of Twin Bridges and its rural western character is a shared priority among the owners, and respect for the community and each other’s privacy is an important part of the Twin Bridges culture. 

The gated main entrance is located half a mile north of Trail Creek Road via a gravel road maintained by the owners. The access road continues north, paralleling Twin Bridges Creek and offering access to each parcel. Twin Bridges Retreat lies just over a mile north of the main gate. Oriented in an east-west direction, the property encompasses bottomlands along the creek and rugged uplands that extend from either side. The creek and its willow-lined riparian area snake through the property for a quarter mile, providing habitat for wild brook and rainbow trout, moose, mule deer, beavers, and songbirds. The cabin sits on an elevated site on the west side of the property and commands outstanding views of the creek and valley below and the Pioneer Mountains to the south. Approximately 40 acres of the property are fenced and cross-fenced with three-rail wooden jack fencing.  

Broker's Comments

Twin Bridges Retreat is a secluded mountain getaway with a beautiful log cabin offering unlimited access to some of Idaho’s best backcountry.

In today’s market, a property of this quality and in this location and price range is difficult to find.

Location

Twin Bridges Retreat lies in the upper Lost River Valley, approximately 25 miles north of the famous all-season resort community of Sun Valley and 30 miles northwest of the small ranching community of Mackay. Access from Sun Valley is less than a 45-minute drive over Trail Creek Pass from May through November. As mountain snowfall begins to accumulate late in the year, Trail Creek Pass closes until spring, and primary access to the ranch shifts northward. Access during the winter months involves driving through Mackay via US Highway 93 and then south on Trail Creek Road. 

Friedman Memorial Airport (SUN) in Hailey, 15 miles south of Ketchum/Sun Valley, is the nearest commercial airport and offers regular air service on Delta, Horizon/Alaska, and United. Idaho Falls, approximately two hours southeast of the property, provides alternate commercial air service out of Idaho Falls Regional Airport (IDA) on American, Delta, and United. Mackay is home to a 4,400’x60’ asphalt airstrip capable of accommodating larger twin-engine aircraft. Of interest to backcountry pilots, a state-owned and managed 4,450’x100’ turf airstrip is located near the entrance to the property along Trail Creek Road. This runway features a windsock, perimeter markings, and tie downs.

Locale

The Lost River Valley is considered one of Idaho’s most scenic areas and is among the state’s top regions for outdoor recreation. The stunning Lost River Range flanks the east side of the valley and spans over 70 miles from Arco to Challis. The Lost Rivers claim seven of Idaho’s ten peaks over 12,000 feet, including Mt. Borah, the state’s highest peak at 12,662 feet. Various ranges, including the Pioneers and Whiteknobs, extend westward from the valley, providing incredible vistas and miles of backcountry to explore. The Big Lost River meanders through the valley, providing irrigation water for farms and ranches as well as outstanding trout fishing opportunities. Four miles north of Mackay, the Mackay Dam impounds the Big Lost River, providing camping, boating, and fishing opportunities.

Sun Valley, Ketchum, and the other Wood River Valley communities of Hailey and Bellevue are a short distance from Twin Bridges and offer a suite of exceptional summer and winter activities, including golf, hiking, fly-fishing, mountain biking, and world-class downhill and Nordic skiing. One will also find numerous gourmet restaurants, art galleries, shopping opportunities, and cultural events to enjoy.

Mackay, with a population of 566, lies at the heart of the Lost River Valley and serves as the local service and social center. It is an agriculturally based community, although its roots go back to the mining days in the early 20th century. All general amenities can be found in Mackay, including groceries, fuel, restaurants, and sporting goods. Each June, Mackay holds its famous rodeo event, “Idaho’s Wildest Rodeo,” which attracts competitors and spectators from across the region.

Recreational Amenities

Recreational Considerations

The upper Lost River Valley offers a variety of world-class recreation opportunities. Trout fishing, big-game hunting, horseback riding, mountain biking, UTV riding, hiking, and wildlife viewing are all outstanding and enjoyed either on-site or minutes away from Twin Bridges Retreat.  

Trout fishing is among the most highly pursued activities in the area. The Big Lost River is a mid-sized freestone stream that originates high in the Pioneer and Boulder Mountains and is a destination for fly anglers from across the region. Quality reaches of the Big Lost are located minutes away from the property, and public access is available throughout the upper river on BLM and Forest Service lands. Trout fishing is also available on Twin Bridges Creek, where small rainbows and brook trout eagerly rise to dry flies. The property features a beautiful stretch of the creek offering numerous pools, meanders, and undercut banks.  

For the upland hunter, chukar partridge are abundant on the lower sagebrush and grassy slopes, while blue grouse are common on the higher elevation Forest Service lands. All of Idaho’s big game species can be found within proximity to the ranch.   

For the hiker or horseback rider, the upper Big Lost area enjoys some of the state’s most spectacular high country. In addition to unlimited cross-country hiking and riding opportunities, an extensive public lands trail network provides access to the area’s vast alpine riches.
