Like every river, the Danube comes from small beginnings. It rises in Fürstenberg palace park in Donaueschingen only to seep underground at the Danube Sink on 150 days of the year. But it soon re-emerges before reaching Ulm, home to the world's tallest church tower, and picturesque Donauwörth, on the Romantic Road. It then passes through the spectacular Danube Gorge. In UNESCO World Heritage Regensburg, there are almost a thousand monuments in the old quarter. The German Danube route, part of the EuroVelo 6 European long-distance cycle route, ends in Passau.
