In reply to SeanSmith:
No huge fences. My understanding is it is part of a farmer's land. I have always been under the impression that as long as you are discrete, and generally abide the countryside code
then all is ok. Also if you are doing any of the routes don't whoop and holler at the top of the crag as you're brining up your second. Also park down the road and not by the bit where you enter the wooded area.
Its a lovely place, with some great problems. Have fun.
Ps. I'm sure someone will be along soon to put me right so... caveat - the above is only what I have been told and abided by.
