Krumme Lanke is a glacial, elongated lake located in the southwest of Berlin, bordering the Grunewald forest. Its name translates to 'crooked bend,' referencing its distinctive, winding shape. The lake is connected by a narrow channel to the neighboring Schlachtensee. The perimeter features a well-maintained 2.5-kilometer jogging and walking trail through woodland. Several sandy beach sections exist along the banks, specifically popular for swimming during the summer months. The water quality is consistently monitored, maintaining high standards suitable for recreational use. It serves as a primary local recreation area for Berlin residents, particularly those residing in Zehlendorf. The lake is entirely surrounded by mature trees, providing significant shade during warm weather.
