Climb a short offwidth to a chimney/tunnel. Tunnel through this to the back side of the rock. You will be wiggling like a worm through this section, just don't get stuck! A whole lot of adventure here for a boulder problem. Highly recommended.
This climb will be harder to start if you are short.
I have not tried going straight up above the tunnel but it looks like it may be an option for the bold.
Location
On offwidth rock, facing the road. This rock is located on the east hill of Santee Boulders. The rock itself is one of the larger rocks at Santee.
