I visited Bamberg in June 2013. I was very lucky with the weather which was sunny contrary to what had been forecasted till the day before. Perhaps this was one of the reasons why there weren't huge crowds of tourists, who knows? I did not complain and explored all the sites the city has to offer and enjoyed walking through the narrow winding alleys and found a couple of welcoming and quaint beer gardens in the process. The Rathaus is an incredible sight, seeing is believing as they say. It appears to be almost floating in the middle of the river and is adorned with colourful murals on its sides. To me, Bamberg is one of the top WHS Germany has to offer and definitely well worth a visit!
