Kaltenbronn, Nature reserve in Northern Black Forest, Germany
Kaltenbronn is a protected nature reserve in the northern Black Forest characterized by peatlands and lake systems. The landscape sits at roughly 900 meters elevation and consists of marshy terrain surrounded by forest.
The landscape formed following the last ice age when glacial retreat left behind conditions favorable for peat accumulation. Over thousands of years, thick organic layers developed in areas where water remained trapped by underlying rock.
The area serves as a place where visitors can understand the relationship between forests, water, and wetlands that shape the local landscape. Walking through it reveals how different plant and animal communities depend on these specific conditions.
Wooden boardwalks provide safe access through the wetland areas without damaging the ground. The paths are generally easy to walk, though wet conditions can make surfaces slippery in places.
Two connected lakes, Wildsee and Hornsee, sit within this protected area as a rare pairing in the region. Their presence makes this one of the few places where visitors can observe both open water and bog ecosystems side by side.
