In reply to Keith Jones:
The Cardiff wall is going to be a retail/indust unit behind TGI Fridays and across the railway tracks on the Newport Rd side of Splott. If you look online, the planning permission application to put in new windows is there for everyone to see.
It will nice and accessible from the A48, so that's ace!! It's not very tall though...I drove past the units the other day, and even the tallest can't be more than 27-29ft??? I asked at WICC and their walls are 50ft+. Hope its not a let down after all the Cardiff wall hype...I've been dying to find somewhere to climb closer to the City!!
