- Trail Creek Road is an 80-mile drive on gravel and paved roads from Sun Valley and into Challis.

- The roadway has steep drop offs and is often plagued with rockslides and/or washed out areas.
A trip over Trail Creek Road is not for the faint of heart. There is a reason that heavy vehicles and vehicles pulling trailers are not allowed on this "trail". The gravel, basically non-maintained roadway is closed during the winter months, but is plowed open when warmer weather comes back to the area. For a heart-stopping thrill, try the scenic route between the Sun Valley area and the Big Lost Valley known as the Trail Creek Road. For locals, this road is used as a shortcut to U.S. 93 and access to Mackay and Challis, Idaho.
The rough, gravel – barely two lane – roadway has steep drop offs and is often plagued with rockslides and/or washed out areas. Only passable during the summer, the road is closed by double-digit feet deep show during the winter. Many times during the winter, the road is also damaged by dirt and rock avalanches. Opening the "trail" each spring generally takes 4-6 days and a concerted effort by a large road grader and its driver.
From Sun Valley take the Sun Valley Road north toward the mountains. Before long you will be on the Trail Creek Road and making your way up to the top of Trail Creek Summit.
Trail Creek Road is an 80-mile drive on gravel and paved roads from Sun Valley up a pleasant valley and over Trail Creek Summit, east to the base of Borah Peak, Idaho’s highest point, through Grand View Canyon, and into Challis.
