Peering down into a running river, there are many things we’d expect to see, from rocks, to fish, to plant life. But a boy in Austria looked into the Danube and saw something moving through the water that was completely stunning.
It is incredible to think that the start of the Danube is formed at the mouth of two streams in Germany’s Black Forest. From there, it grows into the European Union’s longest river and the second-longest on the continent.
The Danube snakes its way through ten European countries: Austria, Bulgaria, Croatia, Germany, Hungary, Moldova, Romania, Serbia, Slovakia and Ukraine. Its path cuts through four countries’ capitals too – Belgrade, Bratislava, Budapest and Vienna.
