This is a unique and fun ride that involves slickrock and riding through a long and dark storm tunnel under the freeway. The slickrock area is a bit confusing with signage, but there are several options on the rocks so just go with the flow. There wasn't much paint on the rocks for a trail to follow, but that is fine too. It is best to ride probably in clockwise order, but overall it is a good intermediate trail to enjoy some freeriding on the rocks for a short loop.
Start from Highland Park and ride a maze of singletrack that winds along the mesa to where you drop down a road to the storm drain. Check for riders coming down and then go for it (assuming there has not been raining).
