From its headwaters in the Black Forest of southwestern Germany, the Danube flows through some of the most beautiful landscapes in Europe. Pristine flood-plains, picturesque villages and small towns, and a wealth of cultural landmarks line the river as it begins its long march to the distant Black Sea.§These tranquil valleys are also ideal for cycling. In recent years, many of the paths and lanes along the river have been paved specifically for bicycle tourists. As a result, almost the entire route follows smooth quiet roads that make it ideal for families with children. sakriti opis
