In reply to jules699: Climbed both at horseshoe and Harpur Hill, both pretty similar id say, quarried limestone is never going to hold the same sway as natural. Well bolted and easily accessible mind you. Id say the area down to the left of the main section is the best for easier stuff, round Christian Salvage Man etc.
As for access, Ive always parked at the Cafe and never had any bother with anyone asking me to leave, the old warden from the depot does wander up and say hello sometimes, but never been asked to move on!
