The birthplace of the Vltava lies in the Bohemian Forest. Dark yellow, like heavy gold, it fills its bed. The golden river, which has repeatedly overflowed its banks, has inspired poets, architects and composers. Today, badgers and wolves are just as much at home on the Vltava as the ground squirrel and the pouched tit. Moose are once again living in the moorland on the upper reaches of the river.
