You can do a lot off of this road. To my understanding, it goes all the way into Challis or there is a semi-loop. I went out and was picked up after 5 mile creek. Really pretty ride, mostly easy terrain. I had to go up a steep hill toward the end after Custer Camp. Great ride following creeks, and to see high ridges, historical areas of dredging, Bonanza, and the old ghost town Custer. Lots of camping opportunities.
