South Crane Road runs from just east of Weiser, OR, to Crane Creek Reservoir in the north. You'll see the West Mountains and the Sawtooth Mountains to the east and rolling hills all around as you drive down the windy, well-maintained gravel road.
You'll travel through BLM land, so camping is allowed off the road. The spur to the trail's north end will take you to the reservoir, traveling a slightly rougher dirt road, but no 4WD is required. This is an open range, so watch out for livestock.
