Beautiful trail on the Wilstedt quarry lake. In winter only with a mountain bike, in summer you can also go on a gravel bike and then into the cool water. The lake is near Norderstedt. The lake can be reached from the surrounding towns of Tangstedt (about 2 km from the lake), Henstedt-Ulzburg (5 km away) and Wakendorf II (about 6 km away).
