Approach as for Muline crag, then skirt around the left end this crag. Head up and right to the next band of cliffs (keep an eye out for cairns) and up a scrubby gully. The crag is a little further right and downhill from here.
Descent: there is a bollard on the far right (facing out) of the terrace at the end of Whipping Boy. It's fairly low down and requires careful scrambling to reach. As of 09/15 there was a healthy collection of tat around this. Double 50m ropes get you to the bottom of the gully.
