Park at the second parking lot up a steep hill ("Scenic Overlook", not by bathrooms), walk to the ledge, and head right on the upper trail. Hike on this trail for 10-15 mins until you get to a fork, with a bench a little way down the curving right fork. Take the straight/left fork, continuing along the ledgetop for 1-2 minutes until you see another fork (see pic). Go left here and head through the narrow mini canyon, walking across a large hollow log. When you emerge on the other side, you will see a long passageway with a mossy wall on the right. There are a few routes on the left wall. Additional routes, including Vacant Fractal, are accessed by following the wall around to the left.
