In reply to phil666:
You are right, a cracking place with lots of powerful problems. I have only been once myself, but I was impressed. Similar to many other boulder venues in the district, the routes or variants of them have probably all been climbed over the years.
But to my knowledge, other than a passing reference in the old Clwyd guide, they have not been documented. If you want to share, you could produce an on line topo. This could help the place become more popular, but I doubt it will be so popular that you could just turn up and meet others as you would in the Peak or Yorkshire.
