In reply to richard kirby:
I would very much recommend Gastlosen. Absolutely stunning scenery and only 10 minutes from the car. Single pitch, multi pitch, south facing limestone (very rough texture and a pure pleasure to climb on).
In particular I would recommend Nikita, which is a fully bolted (not run out) 16 pitch extravaganza, and it's quite frankly amazing that this crag isn't better known and frequented by us Brits.
Nikita goes free at 7b but I think is only 6c obligatory. It's also possible to just climb it for the first 9 pitches to the half way ledge. As far as I remember this was up to 6c or 6c+ (but very reasonable at that grade). We did the latter because Bonner bottled it. I was up for the full thing (honest).
