Some Lizard details:
Mullion Cove has a few good bits on serpentine. Including the video in this thread.
Poltesco has a small circuit again on serpentine, with a couple of ok aretes at about 6B each. Ed's aforementioned stuff similarly on serpentine. IMO most of the serpentine is a bit too far on the wrong side of chossy to actually be good. Whenever the sea gets at it properly it improves a lot.
I developed Lizard Point a few years ago, which I think is by far the best area on the Lizard. Easy access, ok rock, enough to go at. Some details on UKC.
A few bits:

Including this:

Lankidden Cove has recorded stuff on UKC which is absolutely rubbish. Don't bother with that. Nice beach though.
Finally, Porthleven beach has some amazing shapes that got me all excited on first acquaintance, but it turned out to be weirdly soft and spoogy shale. Worth a play if you're nearby.
