This trail takes riders from the area near the Quail Meadows picnic area (starts in the overflow parking across the street by the eucalyptus trees) all the way up to the top near the entrance to the Pipeline Trail
Some sections are very steep and there is one steep loose section that you should avoid in both directions and take the Toyon Ridge Alternate
(though it is a bit rutted and difficult also).
From the top, there are great views. Overall, this is a great climb, with some pretty fun sections.
