This trail lives up to its name...it is technical, rocky, and steep singletrack winding up the backside of CSL. The first part of the trail winds through seasonal streams and oak groves while the second half becomes more exposed and views of San Luis Obispo abound.
From Lemon Grove Loop
at its intersection with CSL Perimeter Trail
take an immediate left after the cattle guard and start a steep climb. From here, when in doubt, continue left and uphill as a general rule until you reach the fire road at the very top of CSL. About a quarter mile into the hike, there is a 3-way intersection with a MTB bell station, take a left and continue uphill. Taking a right will lead you back to the CSL Perimeter Trail
. At the top of the hike, this trail terminates into the CSL standard route fire road, take a right and the top of CSL is a few hundred meters uphill.
