The Vltava is the longest river in the Czech Republic, running southeast along the Bohemian Forest and then north across Bohemia, through Český Krumlov, České Budějovice and Prague, and finally merging with the Elbe at Mělník. It is commonly referred to as the "Czech national river".

The Bohemian Forest, known in Czech as Šumava and in German as Böhmerwald, is a low mountain range in Central Europe. Geographically, the mountains extend from Plzeň Region and the South Bohemian Region in the Czech Republic to Austria and Bavaria in Germany, and form the highest truncated uplands of the Bohemian Massif, up to 50 km wide. They create a natural border between the Czech Republic on one side and Austria and Germany on the other.
