"It would be a win-win-win for Berlin. If the initiative called Flussbad – which translates to “river bath” in English – clears its remaining bureaucratic hurdles, it would not only enhance the city’s already flush tourism portfolio, it would also send an important environmental message, encourage Berliners to indulge in perhaps the healthiest sport there is, and provide recreation for all ages in literally the exact center of Berlin."
