Found this place after discovering Bog Springs Campground full on a Monday. Proctor Road is back down Madera Canyon Road near Whitehouse Trailhead and Picnic area. The road is gravel and the first little stretch is a rough dip with some larger stones. Our 25 foot Class C cleared, but use caution with low clearance vehicles. After that the road improves and there are 10 designated dispersed sites separated by lots of distance. Some sites are large enough for trailers up to 20ft and /or a couple of rigs. We stayed in site 1, so only drove in maybe 1/4 mile or less. We walked down the road to scout out the other sites. Very nice views of the valley and the mountains, and very private compared to the busy Madera Canyon road. Nice little creek (we crossed in the dip) for our golden retriever to cool down! No fees, no services, except 2 bar AT & T. A few cows in the area.
