In reply to All:
My OP was a bit tongue in cheek (particularly the downclimb). I have climbed on good solid Ogwen rock in p*ssing rain and thoroughly enjoyed it in a rather masochistic way. Coming down from the slabs this time i was recalling having soloed up the snowed up gulley into the nameless Cwm to do some winter routes and, yes, the whole place is far better "out of season". It wasn't my 1st choice on Sunday but events dictated it seemed the most sensible at the time.
A long time back it was where I spent my 1st day climbing ever. I suppose it didn't put me off. And I have been there a fair bit over the years and have fond memories of it. The last couple of times I have visited (separated by quite a few years, maybe six) I have had similar experiences, however, and this was just once too often. I suppose what I really meant was that perhaps, other than for relative novices, it is a pretty poor experience in the summer.
Aa Chris (?) said, wrong crag, wrong time or similar.
