The Wahnbach reservoir in the Rhein-Sieg district is an impressive destination for hikers and nature lovers, captivating with its vastness and strictly protected nature. As one of Germany's most important drinking water reservoirs, it supplies around 800,000 people in the Bonn/Rhein-Sieg region with soft drinking water. Since the entire area is designated as a Zone I water protection area, you can expect exceptionally pristine flora and fauna here, which you can explore on numerous trails. A special highlight for ambitious hikers is the approximately 23-kilometer-long Wahnbach reservoir trail, marked as the Erlebnisweg Sieg. The route circles almost completely around the body of water and, through the constant alternation between dense mixed forests, open meadows, and hills, repeatedly offers new perspectives on the glittering lake. Those who prefer a shorter route will find beautiful circular trails with moderate inclines around places like Happerschoß, Seligenthal, or Wolperath. Particularly worthwhile is the view from the 53-meter-high and almost 400-meter-long dam near Siegburg-Seligenthal, which provides an impressive overview of the valley and the technical facilities. However, due to strict drinking water protection, there are some important rules to observe that will affect your visit: Swimming in the lake is strictly forbidden for humans and dogs. Any form of water sports, fishing, or entering the shore areas is also prohibited. Hikers and cyclists must strictly stay on the marked paths to avoid endangering the sensitive nature and water quality. Picnicking and barbecuing are also not permitted in the direct protection zone, which is why it is advisable to take breaks in the adjacent villages or at the official rest stops. Getting there is uncomplicated. An ideal starting point is the large hiking parking lot directly below the dam in Siegburg-Seligenthal. Alternatively, parking is available in Hennef-Happerschoß or Neunkirchen-Seelscheid (Wolperath). Those arriving by public transport should best use the bus connections from the Siegburg or Hennef train stations to the Seligenthal stop. As the paths are partly natural and can become slippery in wet weather, sturdy footwear is absolutely recommended. A visit is worthwhile at any time of the year, but especially in autumn, when the colorful foliage is reflected in the deep blue water.

You are here in the water protection area of the Wahnbachtalsperre, which is considered a particularly sensitive area. Please note that heavy use by mountain bikers will result in vegetation being disturbed and irreparable damage to trees, shrubs and soil may occur. The multi-layered structured forest with the adjacent water change zones serves as a habitat for an enormous variety of species, which is also endangered. In addition, the forest floor has a filter effect, thereby contributing to better water quality and also serves as protection against erosion. For this reason, it is important not to leave the signposted hiking trail. This also applies to vantage points along the trail. Please do not leave any rubbish behind, take it home with you or dispose of it in the rubbish bins provided. To protect the drinking water resource, we ask that you comply with the specifications.
