(German, 'Devil's Lake') is a glacial lake in the Grunewald forest in the Berlin borough of Charlottenburg-Wilmersdorf.[1][2]
The Teufelssee in Grunewald forest is not to be confused with the lake of the same name in the Berlin district of Köpenick.
Nude bathing is permitted at the lake as in many parts of Germany.[3]
The lake's western and northern banks belong to the Teufelsfenn and thus to the 13.1-hectare Postfenn and Teufelsfenn nature reserve. The southern shore is a swimming area.
The oldest surviving waterworks in Berlin, the Teufelssee waterworks built in 1872-3, are located on the east bank. The waterworks were decommissioned in 1969, and today belong to the Naturschutzzentrum Ökowerk Berlin.
To the north-east is Teufelsberg, an artificial hill made from heaped-up rubble of the Second World War.
Teufelssee is of Ice Age origin. It lies in the Teufelssee-Pechsee-Barssee channel, a glacial meltwater channel. All of the lakes in the channel with no outflow were created by dead ice.
