We will meet in the tiny village of Nüxei, a district of the town of Bad Sachsa. The tour starts at the entrance to the village. From there, we will walk a short distance along the new road and then enter the Sülzensee-Mackenroder Wald Nature Reserve, where you can admire sinkholes, stream sinks, giant trees and extensive beech forests. Today, it is quiet here, whereas in earlier times, a variety of events shaped the area and left traces that you can still find today. We walk along almost forgotten paths and old borders, discover old construction projects that were never completed, and enjoy beautiful views of the Harz Mountains. Insights into the flora and fauna of this region round off this wonderful walk.
