In reply to James Oswald:
I've done the VF there (currently closed) and there's got to be more DWS than you can shake a stick at, however it does catch swells, and you'll want a boat - accessing much of the area might be impossible otherwise. There's also a big stack a short way offshore too. Also look at Pain Di Zucchero if you're down at the SW end of the island.
