In reply to matt perks:
We (my brother and I) were there last month poking around, there´s a few cliffs on the East side which could be o.k. but in an extremely adventurous way (and that´s from a combined 90 years of adventurous sea cliff climbing)!
The top-out´s are pretty well impossible and the whole area is a nature reserve so bashing stakes in is not going to be approved of. You´d need to get boat access and lower-off.
There are some sport routes on the East side in the old quarry areas as you go toward the cape which looked so vile that we didn´t bother.
