Once you pass through Ione you will make it to the tribal reservation with a north/south road. At this point it says go straight at the intersection. Quite simply, you can't because the road isn't there. Go left, drive 100 feet, then turn right on Tribal Route 2. Set your odometer.
In .1 miles you will cross the Reese River
At 1 mile you will turn right on Columbine Road (it has a sign for Columbine CG there)
At 2.7 miles stay right at this intersection (has sign for Stewart and Clear Creek)
At 5.6 miles stay right at the sign for the Toiyabe National Forest
At 5.7 miles there will be a water crossing (during drought it could be dry)
At 6.3 miles there will be a cattle guard
At this point continue up the road to the campground a few miles distant. In October of 2016 I did the road in a Honda Civic Hybrid so high clearance should not be needed until snow flies or the road degrades considerably.
