I'd been there yesterday with a couple of German friends and their family. Forcheim is a small and pleasant town close to (or part of) 'Frankische-Schweiz' (Franconian Switzerland). The best part is that, these places are its a bit typical and you dont see many tourists around. So, you can have a feel of festivals in Bavarian (or more precisely, Franconian) style. It was pretty hot yesterday, but the location in the woods and the drinks, gave us some respite.
Also, 'Frankische-Schweiz' (Franconian Switzerland) is said to have the most number of private breweries in the world. So, its worth it, to try different beer' over there.

Infact, in this part of the year, its commonplace for the cities/towns/villages to hold these festivals. There are lots of fests happening at the moment all over Franconia/Bavaria.
Apart from that, I also went to 'Nuremberg Classic Air Festival' (Picnic Im Park). It was nice to lie on the ground and listen to the music. For the last song, all the people stood up with candle lights/sizzling fireworks in their hands. It was awesome to look at that scene, in the dark.
I would also like to inform you folks about the event in Nuremberg (next week), called '
BardenTreffen' (meeting of the bards). There are 60 bands (not bigtime bands, but bands from all over Europe/world), who will be playing at many main parts of the city.
