We went to Hamburg, Germany to celebrate the New Year in 2008. We lived in Germany at the time and my friend was dating a guy who lived in Hamburg. We met up with them there and spent a few days hanging around the city and having fun at the Christmas market. We also went to a New Year's eve party and it was great.
Weihnachtsmarkt also known as Christmas market are very popular in Germany. It is basically a street market associated with the celebration of Christmas. It was by far one of my favorite thing about Germany. They are definitely a must see if you are in Germany during the holidays.
