In reply to PaulTanton:
I'd imagine it's pretty quick drying as it gets a fair amount of morning sun - in fact not much of it will get wet as it's quite steep!!
As for how clean it will be - I'd expect cobwebs and some amounts of cornflake lichen on the faces. Considering how often it gets climbed on it's pretty clean.
What routes are you hoping to do? I think it's a great crag in a lovely valley. I'd whole-heartedly recommend Astoroth (expect a tussle!), Oriole (apparently Phoenix is better but I haven't done it and blasting up the wall is exciting on Oriole), and Snowdrop (one of the best E4s I've done in North Wales). Haven't done Phoenix, either of the Clonus routes or Astoroth Direct but they all look great!
Don't expect soft-touches!
Have a great time and report back how you got on!
