Have you ever felt the cool embrace of glacial water? Welcome to Teufelssee a hidden gem nestled within Berlin’s Grunewald forest. This isn’t just any lake. Teufelssee meaning Devil’s Lake holds a captivating history. It was formed during the Ice Age a remnant of a glacial meltwater channel. Imagine the massive glaciers carving this landscape millennia ago. Today the lake’s calm surface belies its dramatic origins. Teufelssee’s waters are surprisingly clean. Despite its popularity as a swimming spot the water quality remains excellent. The Landesamt fur Gesundheit und Soziales Berlin diligently monitors the lake. They even account for fecal contamination from bathers and wildlife. Don’t worry though the water is still considered excellent for swimming.
Teufelssee boasts a unique charm. Its southern shore is a designated bathing area. Here you’ll find a mix of nudists and textile-clad sunbathers. There’s no fancy infrastructure just nature and a floating pontoon in the middle of the lake. It’s a wonderfully casual atmosphere. The northern and western banks are protected. They are part of the Teufelsfenn nature reserve. A beautiful and tranquil space. This area is fenced and swimming is prohibited here. In fact dogs are banned from the lake itself though they must be leashed on surrounding paths.
The eastern bank holds a piece of Berlin’s industrial past. The Teufelssee waterworks stand there. Built between 1872 and 1873 they are the oldest surviving waterworks in Berlin. Though decommissioned in 1969 they remain a testament to the city’s history. Today the waterworks belong to the Naturschutzzentrum Okowerk Berlin. Looking northeast from the lake you’ll see Teufelsberg. This artificial hill was created from World War II rubble.
Teufelssee is home to the European bitterling. This rare fish is classified as very vulnerable in Germany. It’s part of a fascinating symbiosis with swan and painter mussels. Protecting this delicate ecosystem is crucial. Fishing is strictly prohibited in Teufelssee. To maintain the lake’s water level groundwater is constantly fed into it. This also helps preserve the adjacent Teufelsfenn moor a valuable biotope.
