In reply to cb294: Agree the Trubach valley is well worth a visit and is the area most people end up in on their first visit. Worth looking at would be the classic Fight gravity 8+ or if you like caves then
Orang Utan 9- Wolfsberger Grotte is a cool route. Also well worth a visit is Schlosszwergwand this is a large crag on two levels with a mixture of vertical often a little runout routes and very steep shorter routes, it has been very busy there the last two years though and is not good if it rains.
I would say you need a car, especially in the bamberg area. Its a good 30/40 min drive to Trubach from there, action direct area is around 1 hour away. closer to you and also really good is the area around Waischenfeld, Andeltodrom is a very steep short crag which is good in nearly any weather with good routes from 7+ to 9+. A drive along this valley is a must with loads of impressive crags either side of the river.
