Start on the left face of the boulder (if you are facing the front with the painted guy). The climb starts on rounded rail with a sit start, right hand move, then bad heel, and bump left to a slopey pinch. Keep your feet, make a big move (if you're not tall) up to a jug, and top out straight up.
This is pretty far down the trail, on the left. It is not visible from trail, but you'll walk through a corridor with blocks on either side, then it's up the hill on your left. This is on the only tall boulder.
