Alfords Point - I remember this being OK. However I have never gone back as the SES sometimes use it for abseiling practice and I heard they got stroppy with the climbers. Could all be a vicious rumour though.
The Wok. Never go there.
BlueBells. Pass on this one. Its ok if you have done every other crag in southern sydney and are looking for something new. Same for all the other smaller crags in Sth Sydney
As you may have guessed, I am not a crag snob. Its all good if you are climbing - except for heathcliff in the blueys, which just sux (Ooooo, contraversial!)
