The wall on the West side of the main canyon is actually part of a big free standing boulder/tower. On the back side of this boulder are a handful of overhung 5.10 - 5.11 routes and a few easier problems.
Head down the stairs on the trail from the parking lot and take a left at the fork. Head into the main canyon, but after you pass a boulder and before you enter the canyon take a right. The climbs can be found on along the wall next to you.
