The Long Canyon road #135 used to allow camping at the rim but now that entire area is closed to camping. So back a ways and on BLM road #135 Long Canyon Well Road, there are still free dispersed sites. However, most side roads are rough sandy rocky narrow two-tracks that are ok for overlander types but NOT TTs or RVs. Note there are oil/gas wells in area and any good road likely ends at a oil/gas pad facility. Cell signal varies depending on location. Free dispersed, no water, trash or designated sites. Some State land mixed in also.
