The Berounka is a river in the Czech Republic. It carries the name Mže (German: Mies) from its source in Germany, next to the Czech border, until its confluence with the Radbuza in Pilsen. It then continues under the name of Berounka until it enters the Vltava on the edge of Prague. The river is a favourite destination among canoeists, who enjoy the picturesque sceneries around, especially when it flows along the Křivoklátsko Landscape Protected Area where three castle ruins erect over the Berounka river valley. <a href="http://en.wikipedia.org/wiki/Berounka" rel="nofollow">en.wikipedia.org/wiki/Berounka</a>
