In reply to Welsh Kate:
Hi
I have taken that traverse path along the N face of Cribyn (many years ago when in a hurry), and it didn't feel very stable then. Not surprised it is expected to fall. I'll take at look at the path from cwm Sere you mention, thanks. You say it is a grassy scramble, and that is problem, what we don't seem to have are any rocky scrambles.
I do climb (low grades) when I can get a partner, but am just as happy scrambling nowadays. Just had a few days enjoyable days in the lake district and scotland, which prompted me to ask the question. Only recently moved back to the area and was hoping there was something I had missed.
