The center of the Märkische Schweiz Nature Park is the 140-hectare Schermützelsee with its characteristic turquoise water. Situated only 50 kilometers east of Berlin, it almost has a Caribbean flair. The lake, which can be over 40 meters deep, probably originated from a gigantic melting block of ice in the Ice Age. The excellent water quality makes Schermützelsee a great swimming lake. Swimming is best done from the lido at Buckow, as entrances are otherwise rather difficult. All the more peace and idyll you will find at this lake, around which it is also excellent to hike.
