The Vistula ( /ˈvɪstʃələ/; Polish: Wisła, German: Weichsel) is the longest river in Poland, at 1,047 km (651 miles) in length. The watershed area of the Vistula is 194,424 km2 (75,068 sq mi), of which 168,699 km2 (65,135 sq mi) lies within Poland (splitting the country in half).
The Vistula rises at Barania Góra in the south of Poland, 1,220 meters (4,000 ft) above sea level in the Silesian Beskids (western part of Carpathian Mountains) where it begins with the White Little Vistula (Biała Wisełka) and the Black Little Vistula (Czarna Wisełka). It then continues to flow over the vast Polish plains, passing several large Polish cities along its way, including Kraków, Sandomierz, Warsaw, Płock, Włocławek, Toruń, Bydgoszcz, Świecie, Grudziądz, Tczew and Gdańsk. It empties into the Vistula Lagoon or directly into the Gdańsk Bay of the Baltic Sea with a delta and several branches (Leniwka, Przekop, Śmiała Wisła, Martwa Wisła, Nogat and Szkarpawa).
