In my younger days I would have said Mayfield but you have to be in pretty good shape to do the walk through the river and falls. If you are up to it I highly recommend it. You will have a guide with you and ours was very helpful. First time we went to YS was not long after they opened to the public and we loved it. Now it's all built up and I see they even have zip lines (shudder). Still well worth seeing and you can do it as part of a South Coast trip.
