In reply to Radarbailey:
Castleberg is OK but do take care re. loose rock. I was there cleaning up 2 weeks ago and removed a lot of loose stuff from routes 3-5 (the worst of the loose routes at the crag), route #4 is still a bit loose but the routes either side of it are reasonably sound in comparison - #5 is actually quite good now. That's not any sort of guarantee of course. Giggleswick South has some easy stuff too, but again the very easiest stuff can be a bit loose.
