In reply to Ross B:
Hi Ross,
I've only been there once myself having recently discovered it (as it's only about 40mins or so from my house), but there are a few stakes about 3 or so meters away from the edge. There are also a few further back as well. There was some loose rock floating around so take a helmet with you if you don't normally.
We met someone up there who was giving a lesson to somebody else and he was kind enough to set up a rig for us.
