In reply to Al Doig:
I haven't contacted the Landowner when i've been and I don't know anyone who does. Just make sure you park on the main road and walk to the crag (It's a 5 - 10 minute walk) as people have been known to park outside drive way's nearer the crag on a residents only road and this could effect access.
Also beware if you have a dog, one of the houses you pass when walking in (possibly the landowner) has 2 pretty nasty dogs which jumped over the wall at my friends dog once when we were there!
