In reply to ewanjp:
I just don't get all this negative stuff about Tintern, why spend time and money developing a crag and then trying to frighten people off going there?
I have been there about 20 times, it's a perfectly good crag, big shiny new bolts and lower offs, that 30 foot wall is a great place for lower grade sport climbing, there is a decent range of grades, some trad, some long routes...it can be sunny or in the shade...easily accessible...of course there is some loose rock about, it's hardly terminal though, get down there, you won't be disappointed...
