Start around the corner from the Spider starts. Climb up a rampy beginning until you reach the first horizontal crack. Traverse left and out around the corner until reaching a vertical crack. Finish on Spider Balls.
All these Spider Man climbs finish on the same bit, and there are two bolts up there. They have old hangers and are cemented in place, but might be handy for a quick bail. Don't TR on them. Also, the Spider Man climbs go trad. R to the crack then fine afterwards.
