The warmup starts on the face that looks down toward the houses. There's a thin, weed filled crack you can climb. It is not super awesome, but it is worth while for a warmup.
Park at the teal treatment plant, and walk up the trail for about 5 minutes. On the left, you will see a dirt road and the trail gets washed out for a minute or so. Keep walking up. After a few more minutes, there's a left turn, and right before you make that turn, look ahead. Maybe 100 yards off the trail is a dope looking boulder with a tall crack bisecting its face.
