Surfing is a popular water sport you would not expect in Munich, hundreds of kilometers away from the next coast line. The location is at the Eisbach, which translates to ice brook just next to the Haus der Kunst in Munich. The standing wave can be surfed the whole year, but even in summer the water is very cold.
The history of surfing the Eisbach goes back into the year 1972 (according to Wikipedia).
The Eisbach flows under ground for some kilometers and is a part of the Isar river. After the popular surf spot it flows through the Englischer Garten a large park where you can relax just in the heart of the city.
