In reply to huh:
Ejector Walls is the fenced off bit, with Pumpernickel up the middle of a blankish wall to a fixed peg lower off near the top.
The Over the Moors guidebook says that The Rock Walls are reached by following Torside Road, so I guess they are on the opposite side of the river beyond the mill (?).
Playground is the scrappy bit on the right as you walk down from the Rock Inn.
These bits are all in the Over the Moors guide.
