In reply to J0E W:
Hi Joe, it's basically a hodge podge of information between different guidebooks, UKC, Rockfax and pdfs/blog posts. Essentially most of it takes digging around a lot on the internet and using guidebooks and ukc, and then going to the spots for an initial scoping visit and trying to work things out. I find that's quite often the way with dws (that's not in mallorca or on the south coast major spots).
I'll write a more detailed response later with all the crags I've visited in N.wales and the main info sources for them.
I've been asking about some recently on UKB and Andy Moles has been really helpful, he said he might be writing a mini-guide if there is demand so this might help persaude him... I think it would really help to get more people out to explore the N.Wales DWS as although it takes some effort to find and climb (with tides and weather etc) - it is really good! I try and upload some YouTube clips to show people what the climbs are like and get people psyched for it, i link them on the ukc route video section.
George.
