What are the best places to visit in Germany?

You should go on the Rhine river, the castles are extravagant.

munchen.

Any place that has beer. Emmmmm, beer!

munich - go and eat spare ribs in the jazzbiergarten, and for the clubs... and of course: berlin.

Probably one of the best and most visited area is Bavaria, especially the southern part, i.e. Garmisch (Zugspitze, highest mountain in Germany, Berchtesgaden, the castles in F眉ssen etc.
The most visited tourist attractions/cities are:
1) Cathredal in Cologne
2) R眉desheim
3) Berlin (Reichstag building)
4) Rothenburg
5) Bad M眉nstereifel
6) Heidelberg (castle)
7) Neuschwanstein castle / F眉ssen

I was most pleasantly surprised with Berlin - it's exceptionally cheap and everybody is super friendly and English speaking! There is lot of things to see around the city (Brandenburg gate, Alexander Platz, Sony center,Zoo station etc),it's also great for shopping and clubbing.

BERLIN, OF COURSE!!!!IS THE CENTER OF GERMANY, EVERYTHING HAPPENS THERE. ONE MONTH AGO I WAS IN BAVIERA, NEAR MUNICH, A TOWN NAMED FUSSEN, FROM THERE YOU CAN WALK 5 KMS IN THE NICE FOREST TO GET THE CASTEL OF LUDWING OF BAVIERA, VERY NICE PLACE TOO.AND GOOD BEER!!!!

I think the best places are the smaller towns that were not destroyed during the war, like Rothenburg or Goslar. Old, charming, real.

Garmish, Frankfurt, and definitely Berlin.
