In reply to TimhNorthBASE:
I have the old guide from the RAF PT dept, I did some exploration and new routes back in 2006 as of 2014 the official guide is held at the PT wing APC. Not that I am the guide to the FI but I can direct you around to areas for the best climbing if required. Totally depends on what time of year you are going!! last time i was there within the same week we did new rock climbing routes one day and quality snow and ice routes on the same crag the next.
