It costs £5 (member)/ £7.50 non-member to climb plus hire of kit. (harness £1.50 and shoes £2.50)
If you are not a member you may want to join at a cost of £5.50 (as we may be going to the wall a few times over the coming year).
If they have not seen you climb you will have to demonstrate your skills before being let free.
