South-east of Berlin stretches a mysterious river landscape - more water than land - a region like something out of a fairy tale. Here the Spree ends its swift course and changes its shape. It splits into a network of countless watercourses and islands: The Spreewald. To this day, there are hidden corners of the Spreewald that hardly anyone has ever entered. This is where the black stork, crane and white-tailed eagle have retreated.
