In reply to Darron: We just dropped back down the path towards the parking again, until we found another path on the right which lead round to the base of the next set of crags to the north of 'Solarium.' There is a fairly obvious line of paths running along the base of the crags, although there is a point where you can be drawn into a small gully which has a sign saying private at the entrance. Avoid this, although if you do end up following the path into it, it becomes obvious straight away that you are in the wrong place The crags are quite hidden by trees but are all pretty close together, and we had no problems locating Sector Duck. I can't be more specific, as my climbing partner has the guidebook, and he lives 60 miles away so I can't check the crag names to give you definite details.
On another note, we found the grading here to be pretty hard! At least at the 4/5/5+ end.
