This remote and scenic loop around Yellow Peak, for advanced riders only, follows Big Timber and Rocky Creeks. You’ll start and end on a well-used ATV trail, but the rest of the ride is singletrack, crossing two mountain passes high in the southern Lemhis, southwest of Leadore. Trails here are wide and well defined, making for great riding. Route-finding is a snap, but several stream crossings and tough stretches will wring you out. Sections of upper Big Timber Creek Trail may be eroded, expect to push your bike.

Ride this loop in either direction. But know that the upper end of Big Timber Creek has several chunky rock sections which are fun descending, but not so fun to climb. Either way, this is one of the most scenic and remote rides in Idaho.

Access: From Salmon drive 45 miles southeast on ID 28 to Leadore. Hang a right in downtown Leadore onto Lee Creek Road (aka Farm-to-Market Road). Go about 1 mile west and turn left at the old yellow grader onto Timber Creek Road. After about 7 miles you’ll come to a cattle guard and a forest service info panel. Stay on Road #6105. It is 5 miles from here to the next gate, which closes the road to full-size motorized traffic. Nearing this closure the road gets rough and turn-around spots few, so start the ride where you can park. The Route map above shows the entirety of Road 6105 included in the loop.
