The Krabachtal (Sieg) is an approximately ten-kilometer-long, largely uninhabited valley in the North Rhine-Westphalian Rhein-Sieg district, which forms the natural border between the municipalities of Hennef and Eitorf. Key Facts: • Location & Course: The Krabach originates near Meisenbach (together with the upper course Meisenbach) and flows north until it flows into the Sieg near Eitorf-Bach, opposite Merten. • Ecological Value: The valley is a valuable natural oasis with gallery forests along the stream, quiet forest areas, and wet meadows. • Nature Conservation & Care: Large areas are looked after by the Biologische Station Rhein-Sieg, which uses Moorschnucke sheep, among others, for landscape maintenance. Through the Chance7 project, an old fish pond facility was dismantled, making the stream course permeable again for fish and small creatures. • Leisure & Hiking: The valley is a popular destination for hikers and nature lovers (among others via tours of the Naturregion Sieg).

The local poet Hans Reyhing (1882-1961) described the reward of a wanderer, who roams nature and enjoys its beauties with open eyes, as follows: “The world has a different face every day and every hour, and the yield of our wandering life is… being filled with the infinite diversity and the immeasurable richness of the world.”

Here is the second opportunity to get the stamp for the stage of the Natursteig Sieg! This one also has the Naturregion Sieg logo and is nicer than the stamping point just before Süchterscheid!

The Einsiedlerbachtal valley is a special little stream valley in the Siebengebirge Mountains. The stream murmurs through the beech forest in a deeply cut, narrow ravine. The accompanying path is easy to walk, and is well-maintained. Here, you can also experience where the Siebengebirge got its name: many tributaries of the Einsiedlerbach have cut narrow ravines into the steep slopes on their way down.

A great hiking trail with a moderate incline. In spring, all the plants awaken, a vibrant green glowing from the dreary brown and gray. Old trees with large root systems line the path.
