EuroVelo 6, named The Rivers Route, is a EuroVelo long-distance cycling route running along 3,653 km some of Europe's major rivers, including much of the Loire, some of the Saône, a short section of the upper Rhine and almost the entire length of Europe’s second longest river, the Danube — from the Atlantic coast of France to the city of Constanța on the Black Sea.
The EV6 traverses 10 countries from Saint-Nazaire in France at the mouth of the River Loire, eastward along the Loire to the River Saône, across the border to Switzerland, along the Rhine to Lake Constance, north into Germany, down the River Danube and through Austria, Slovakia, Hungary, Serbia, Croatia, Bulgaria, and Romania to the Danube Delta, before terminating at Constanța on the Black Sea.
