Fact 7

7 most beautiful rivers in the world 

1. Danube River, Europe

At 1,770 miles long, the Danube is the second longest river in Europe after the Volga. But unlike the Volga, which only runs through Russia, the Danube snakes through Germany, Austria, Hungary, Croatia, Serbia, Bulgaria, Moldova, Romania and the Ukraine before emptying into the Black Sea. Vital to the settlement and political evolution of central and southeastern Europe, the Danube's banks are lined with castles and fortresses as it was the boundary between so many great empires. Today the lower portion of the Danube is a major avenue for freight transport, while the upper Danube is an important source of hydroelectricity. 

2. Ganges, South Asia

Hindus believe the Ganges River is the earthly manifestation of the Goddess Ganga, and they worship it as the holiest of all rivers. Beginning in the southern Himalayas, the 1,560-mile river flows through China, India, Nepal and Bangladesh before emptying into the Indian Ocean. Many of the practicing Hindus who populate the 52 cities and 48 towns along its banks believe in the river's ability to cleanse them of their sins and liberate them from the cycle of life and death. Pilgrimage sites are particularly significant, attracting hundreds of thousands of worshippers each year, and some people cast the ashes of their dead into the river, believing it will guide the souls of the deceased straight to paradise. 

3. Jordan, Southwest Asia

The Jordan River is both the Biblical and historical epicenter of the Judeo-Christian world. Not only is it where Jesus Christ was baptized by John, but it is also believed to be the scene of a number of miracles, including the crossing from Egypt to Canaan, and Biblical wars, such as the battle between Jonathan and Bacchides. Though part of the river's upper portion is still used for baptisms today, much of it is considered endangered due to domestic and agricultural use. 

4. Mississippi, North America

The Mississippi River is the largest river system in North America—so large, in fact, that it runs through 10 U.S. states and is divided into two main parts: the Upper Mississippi (from its source in Northern Minnesota to where it meets the Ohio River at the southern tip of Illinois) and the Lower Mississippi (from the Ohio River to the Gulf of Mexico). A major navigational route and settlement hub since the Native Americans settled there, the Mississippi River has been immortalized in American culture in everything from books like Mark Twain's The Adventures of Huckleberry Finn to the rhythm and blues music of the Mississippi Delta. 

5. Nile, Africa

At 4,132 miles long, the Nile is the longest river in the world. It also happens to be one of the most iconic. Flowing north through the deserts of Uganda and Egypt, it has been the lifeline of Egypt since the Stone Age, and, to this day, the vast majority of the Egyptian population is settled along its path. It is also one of the main routes of shipping traffic. In fact, the winter winds are so strong that ships can travel against the current using just a sail. 

6. Neretva, Southeastern Europe

Neretva is the world's largest "karst river" or river surrounded by karst topography, which is the phenomena of rock dissolution that creates caves, sinkholes, sinking streams and large springs. Running mostly through Bosnia and Herzegovina as well as Croatia, the river is considered among the 10 most endangered karst ecosystems—its cold, fresh water is maintained by dams and hydroelectric plants—but is still hailed as one of the most beautiful rivers in the world. Photo: Michael Short/Getty Images

7. Rio Negro, South America

At just over 430 navigable miles, the Rio Negro is the world's largest blackwater river, and forms the border between Colombia and Venezuela. Its color, which looks like darkly brewed tea, is caused by the release of tannins from decaying vegetation. The Rio Negro feeds into the Amazon just below Manaus, Brazil, and is its largest tributary, creating a beautiful contrast of color where the white waters of the Amazon and the black waters of the Rio Negro meet.
