It's actually on the West side of Sierra Ave. The trails are not clearly marked. So when you get there at the park. There's no telling where it starts. Confusing where to go because none of the trails have any signage. The trails are steep and the dirt are light (gets dusty when there's a breeze). The disappointment hiking this trail you'll discover, its another "Trail of Shame" the boulders have been vandalized with graffiti.
