Nonnenmattweiher

The Nonnenmattweiher forms a protected area of 71 hectares in the Black Forest, featuring a glacial cirque lake surrounded by steep rock walls.

The lake was transformed into a millpond in 1758 for fish breeding, but the dam broke in 1922, leading to reconstruction and elevation in 1934.

The name derives from medieval farming practices when the meadows near the lake were used for grazing pigs, called 'nunnen' in the local dialect.

Visitors can access the lake via a narrow road branching from the main route between Badenweiler and Neuenweg, leading to the Fischerhütte restaurant.

The lake contains a floating peat island with rare fen vegetation, separated from the public swimming area by a barrier of floating logs.
