Pleasant hike through the beautiful valley of the Wurm river, a gem hidden between various towns north of Aachen. The edges of the valley are covered with woods and meadows cover the valley bottom around the meandering Wurm. The hike also includes a short and steap climb of Bergehalde Gouley, a heap of mine debris north of Teutenhof. You can find the Bayern-style Teutenhof on the road between Kohlscheid and Würselen if you want something to eat and drink.
You start out at the parking at the end of the Zum Blauen Stein road at the Paulinensaüle. You first walk into the Paulinenwäldchen wood where you descend (twice) to the valley of a small stream, and follow this valley to the Wurm valley. Here you follow a path on the edge of the forest and the meadows surrounding the meandering Wurm all the way to the Kohlscheid-Würselen road. The views on the way of the meadows, Wurm and Adamsmühle are great. You cross the road and continue to the bridge at the Pumpermühle. After crossing the Wurm you climb a bit on the road, and then descend on a path towards the valley floor. Here you also find the “Stollenmundloch Grube Gouley”, a tunnel beneath the mountain where water from the Gouley mine flows through. You then climb quite steeply on a broad forest track out of the valley and walk behind some houses on the edge of a field. You then descend via steps onto a former railway track (Bahndamm), and then steeply ascend on the heap of debris called Bergehalde Gouley. You then follow paths on the edge of a valley with good views until you descend to the Kalkhaldenblick. On the way you find some large stone eggs, and you have a view of the lime heap of the former Solvay plant, a small lake and the Bergehalde Gouley. From here you follow the lower Bahndamm towards Teutenhof. On the way you pass a viewpoint of the Kalkklippen (‘lime cliffs’). You cross the road from the Teutenhof towards the Adamsmühle and follow the semi-paved cycling path along the Wurm valley all the way to Wulfsfurth. Here you cross the Wurm and climb back to the starting point. On the left you see parts of the municipal waste water treatment plant of Aachen.
