The Old Danube and the New Danube are Vienna’s most popular bathtubs. While the New Danube is still connected to the actual Danube river, the Old Danube is not. The inland water spreads over 1,6 square kilometres with an average depth of 2,5 meters (the maximum depth is 6,8 meters). Counting between 700.000 and 1 million bathers per year, the Old Danube is a major recreational area for Vienna’s population. And people do not just visit for bathing, but for all kinds of water sports like rowing or sailing or simply for enjoying the scenery like we did for our recording with Tanzhausgeiger.
