Berggeistweiher

Berggeistweiher is a freshwater lake in southern Brühl, surrounded by dense forest and covering about 14 hectares. The water sits in a natural depression marked by steep banks and woodland, extending to the boundary with the village of Walberberg.

The lake formed during lignite mining operations in the 1930s. It received protected status in 1990 to preserve the habitat that developed in this reclaimed landscape.

The name reflects local folklore tied to woodland spirits and natural forces in the region. Today visitors come to experience the quiet surroundings and the contrast between this protected habitat and the developed areas nearby.

Visitors should stick to established paths along the shore, though the southern access point is no longer available and the northern bank remains the main route. Visit during dry weather when the forest floor is manageable and easier to walk through.

The site was fully closed for several years while experts investigated World War II remnants discovered on the lake bottom. After extensive safety assessments, the area was reopened to the public once authorities confirmed no immediate hazards remained.
