Long Lake

The Lange See is a lake of about 34 hectares located in Garzin, a district of the municipality of Garzau-Garzin in the Brandenburg district of Märkisch-Oderland. The lake is located in the western part of the Märkische Schweiz Nature Park.
The elongated natural lake is part of a side channel of glacial meltwater from the Vistula on the southeast of Barnim, which begins in the 168-hectare nature reserve of Ruhlsdorfer Bruch with the Ruhlsdorfer See and, like the Lange See, is crossed by the Lichtenower Mühlenfließ. The water, which is largely surrounded by forest, is used for fishing and fishing. On the eastern shore, near Garzin, there is a public and natural sandy beach with a lawn for sunbathing. The European Cycle Route R1 passes in front of the lake.
