A tranquil natural idyll in the heart of the Ruhr region. Lake Böllertsee is part of the Sechs-Seen-Platte recreation area in southern Duisburg, an ensemble of six interconnected quarry lakes with approximately 158 hectares of water surface. Biotope conservation and development measures are in place on the southern shore of Lake Böllertsee.

The "holy spring" is a spring in Duisburg's city forest, south of the intersection of Rundweg and Kammerweg. The spring (also called "Marienquelle"), first mentioned in a city account in 1563 on the "hillgen bornschen Berg" (hilly born mountain), was once attributed with healing powers. The origins of this belief in the water's supposed healing powers remain unclear. In reality, the spring water, which seeps through the gravel and sand of the city forest and emerges above the impermeable clay layers, has no such effect (it is not drinking water). In 1935, the spring and its surroundings were lined with stones. Coal mining was carried out here as early as 1562, but without success. The tunnels were said to have been up to 45 meters deep.

The correct name of the parking lot is: Wanderparkplatz Uhlenhorst.
