The Bohemian Forest is a low mountain range in Central Europe. Geographically, the mountains exten from South Bohemia in the Czech Republic to Austria and Bavaria in Germany. They create a natural border between the Czech Republic on one side and Germany and Austria on the other. For historical reasons, the Bohemian and German sides have different names: in Czech, the Bohemian side is called Šumava (pronounced [ˈʃʊmava] (help·info)) and the Bavarian side Zadní Bavorský les, while in German, the Bohemian side is called Böhmerwald (literally, 'Bohemian Forest'), and the Bavarian side Bayerischer Wald (literally, 'Bavarian Forest'). In Czech, Šumava is also used as a name for the entire adjacent region in Bohemia.
