The Vltava, which runs through Prague, is the longest river in the Czech Republic. Its source is in the mountains and forests of Bohemia in the south. It then flows north through the center of the country to merge with the Elbe River, one of the major rivers of Europe that flows 680 miles from the Krkonoše Mountains in northwest Czech Republic to the North Sea at Hamburg, Germany.

The Vltava actually has more water than the Elbe, but since it joins the latter at a right angle, it is counted a tributary.

The Vltava is also known as “The Moldau,” which is the name of the most famous of Czech composer Bedřich Smetana’s six symphonic poems Má vlast (My Fatherland).
