Post from Scottish Climbs, posted on 6th June:
I was wandering in the quarry itself on Saturday, and a friendly member of staff told me, with some regret, that they weren't allowing anyone to climb in the quarry at the moment, due to work being carried out on the top, involving the big fire escape thing. He said that he hoped it would be allowed at some stage, but wasn't sure when.
