Singletrack through a forest of cholla cactus and up a rocky ridgeline to a dirt road, which can be followed uphill (south) to Cerro Piñon. It is hard to find this single-track off the two-track that climbs from SR 503.  Climb the two-track from SR 503 and you reach a distinct summit. The two-track goes downhill and then veers left (north).  Watch for the start of this single track on the right-hand side as it drops down gravel and rocky single track and crosses two narrow and deep arroyos perpendicularly.  After this, you are on a narrow single track with sand traps as you ride amongst a forest of cholla cactus.  Follow this until you leave the cholla area and climb a granitic base single track to Camp Frank Rand Road (County Road 123).
