In reply to ultramarathon2006:
You could have a look at the climbing shop at the Baerenbrunnerhof camping (or call them).
The climbing is great. The trad is very good from II to VI (up to 6a). The sport is very good from VIII (7a). Grade VII tends to be a mix of both: either some bolts and some gear, or bolts with runouts.
I quite like the mixed routes . There are loads of great lines there that I would never try without the bolts, but having a single bolt waiting for you at 10 to 15 meters is a temptation.
