In reply to petegunn:
Yep, organised a club meet there on Thursday. It was very saddening. Half of us bailed to Denham and the others managed to clean two routes and climbed them a couple of times.
There is three feet of brambles around most of the base and the lower section is all but inaccessible. The only line that want totally overgrown was fortunately Mandarin but nobody has the bottle to go for it as it was probably very dusty.
It's sad to say but with the current access restrictions - limited hours for two months per year - are going to prevent it from ever being in great condition.
Really the BMC needs to intervene but it looks like they've done really well just getting us this limited access so I'm not sure what else can be done.
