Vistula River

Vistula River, Polish Wisła, largest river of Poland and of the drainage basin of the Baltic Sea. With a length of 651 miles (1,047 kilometres) and a drainage basin of some 75,100 square miles (194,500 square kilometres), it is a waterway of great importance to the nations of eastern Europe; more than 85 percent of the river’s drainage basin, however, lies in Polish territory. The source of the Vistula is found about 15 miles south of Bielsko-Biała on the northern slopes of the western Beskid range, in southern Poland, at an altitude of 3,629 feet (1,106 metres). It flows generally from south to north through the mountains and foothills of southern Poland and across the lowland areas of the great North European Plain, ending in a delta estuary that enters the Baltic Sea near the port of Gdańsk.
