Start at the concrete platform just N of the Blowhole. Traverse L with feet at the level of the platform (reasonably obvious footholds) until a tricky move leaving the jutting foot ledge. Finish more easily after the corner.
I think this is what I did, it's a traverse all the way from the concrete platform down to the mouth of the blowhole pinacle cave. It's very good and has deep water all the way. andy_pemberton - Solo - 18/Aug/13
