Spent two nights here in August.  There were 4-5 spots in this area, which is right on the San Juan River.  I was here on a Sunday night / Monday night and it was not crowded.  There were a couple of other folks who were there.  There are a couple of trailheads (about 1/2 mile up the road).  I took the Quartz Ridge trail - which was nice - except having to cross a creek .20 miles into the hike).  

I have AT&T and had no cell coverage at all.
