The Kall Dam, known as the Kalltalsperre in German, is a tranquil and natural dam in the Kall Valley near Simmerath in the northwestern Eifel region of Germany, not far from the Dutch border. This dam forms a reservoir that serves as part of the local drinking water supply and natural water management system. It is not used for swimming or water sports because it functions as a drinking water reservoir, and strict restrictions apply to keep the water clean and safe. Unlike larger tourist dams such as the Urft or Rur Dam, whose history and size are legendary, the Kall Dam is especially popular for its natural beauty and tranquil setting. Surrounding the water are forests, meadows, and gentle slopes, perfect for walks through tranquility and greenery. From the Kallbrück Wanderparkplatz car park near Rollesbroich, you can directly follow paths leading to the dam and around the water, making it a popular starting point for a circular walk around the Kall Dam. The hiking trails around the dam are generally easy to navigate and ideal for short or medium-length hikes. Although the dam itself is not a recreational swimming area, the surrounding landscape offers tranquility and a natural experience, with views over the water and wooded slopes that are resplendent in autumn and teeming with life in spring. Birds, small mammals, and a variety of plant species thrive in this environment, making the Kall Dam an attractive destination for nature lovers as well. Access to the dam and its paths is free and possible year-round, as long as you stay on the established hiking trails and respect the area's role as a drinking water supply (so no swimming or boating). From the Kallbrück car park, a circular route leads past the reservoir and through the surrounding Kall valley, making for a peaceful and varied walk lasting anywhere from an hour to several hours, depending on the route chosen. The Kall Dam's location in the Eifel region also makes it ideal for combining with other natural and historical attractions in the region. Around Simmerath and the Kall Valley, several hiking trails lead through valleys, streams, and forests, suitable for both day hikes and longer treks. For those seeking a more challenging experience, there are longer routes like the Kall Trail (approximately 8.8 km) or the Kalltalweg (approximately 7.5 km), which pass through the Kall Valley and surrounding areas. These routes are slightly more hilly and offer a richer view of the landscape.

At the old train station, you leave Sourbrodt and the Vennbahn behind and immerse yourself in the mysterious Venn.
