In reply to Dominion:
Oh, and the Stalagmite/Stalactite combo is a must do. I did 3 or 4 warm up routes, and then thrutched my way up whatever was the easiest route (F6a, I think)..
They do have some routes with autobelays, so climbing in a group of three, I was going up those routes when I wasn't belaying or climbing (and being belayed).
You do need to get a member of staff to demonstrate the autobelay system to you before you use it. I still downclimbed the first route I did on it, as I didn't trust it, so test it out before you get too far from the ground. And don't forget to clip in to them!
