In reply to mark_wellin:
Getting down to the cliff base path from the quarry is indeed the same as ever; either the rope in the gully or the rungs - which, now I've seen them, I can't believe that I'd not spotted before!
Dropping down from the main cliff to the beach climbs is perhaps a little more difficult - the steep muddy slopes down to triple slab seemed just a little more slippery and unstable than I remembered, and the way back up from Diamond slab was pretty overgrown and brambly (in fact, so was the cliff base path back from there to the quarry). Nothing was impossible, but it was all a bit unpleasant, and a couple of the novices I was with found it pretty intimidating.
