Embark on an unforgettable journey along Trail Creek Road, a route not recommended for heavy vehicles and trailers due to safety concerns. This gravel, minimally maintained road is closed during the winter but reopens with the return of warmer weather. For those seeking a thrilling drive, Trail Creek Road offers a scenic path between Sun Valley and Big Lost Valley. Locals often use it as a shortcut to U.S. 93, providing access to Mackay and Challis, Idaho.

The road's rough, gravel surface, barely wide enough for two lanes, includes steep drop-offs and is susceptible to rockslides and washouts. It is only passable in summer, as winter snow accumulates to double-digit depths, rendering it impassable. Additionally, dirt and rock avalanches frequently damage the road during winter. Reopening the trail each spring typically requires 4-6 days of work by a dedicated road grader.

Several turnoffs along the route allow you to either set up dispersed camping or stay in designated campgrounds.
