In reply to BlakeyDerbyshire:
I've only been once or twice. At first I thought it was all a pile of choss but there are worthwhile routes not on the main wall that are more solid than they look.
To the right of main wall and the upper tier above the main wall are not too bad (in relative terms). I've done most of my climbing on sea cliffs though so what many people round here consider chossy seems pretty good to me.
