I vaguely remember coming across a topo for some newish sport routes along the A55. As far as I remember there were between 6-10, up to 6b with some longish ones of maybe 30m. I have not been able to find the topo or any reference to the area when trying to find them again recently. I think they are inland, perhaps between Llandullas and Llandudno. Is the collective memory of the UKC able to pin the topo down with such limited information.
It might have been the ones publicised by V12 on their news feed/blog/Facebook. I recall seeing something a while back (possibly including a comically well bolted, long grade 3 for beginners). Worth a google perhaps.
