Mill Creek winds through standing dead timber killed in the 2013 Elk Fire. Brush and smaller trees are returning after the fire's devastation. Running through the Boise National Forest between Castle Creek and House Mountain Road, Mill Creek is a fun, interesting, scenic, and relatively easy road. The shelf road section views into and across the steep valley to the distant mountains are spectacular!
After less than a mile from the east end, the road makes a hard right and becomes a narrow shelf road cut into a steep mountainside. The primary hazards along Mill Creek include down timber, gullies, washouts, and pin-striping. This is open-range, so watch out for livestock on or near the road. The shelf section has a few pullouts for passing.
While dispersed camping is available along the entire road, it can be difficult to find a place both big and flat enough to set up camp in the shelf road sections.
