This bunker from World War II, where deserted forced conscripts hid until liberation, can be reached via an approx. 1 km-long footpath. The walk is well worth it, as hikers near the bunker are rewarded by an impressive view over the Upper Sûre Lake.
The mill in Kalborn, which is over 200 years old, has developed into a nature conservation centre. Endangered river pearl and brook mussels are bred here. Information boards in front of the mill show how gardens can provide habitats for wildlife and insects.
