In reply to j.hale: I was there for a couple of weeks a few summers ago. everyone seemed to suggest that the authorities were tough on wild camping. we camped up near the base of one of the sports crags with a steep approach (in the guide, can't remember which one). bit of a hike with camping stuff but we were guaranteed to be left alone (wasn't a particularly popular crag either).
use your head and you'll be fine.
