If you are interested in nature, you should definitely count the ant hills on this route. I discovered 70 hills full of life. Some quite flat, others over a meter high. You become a child and forget the time.
Fascinatingly many anthills, sometimes also connected by ant trails on the trail. A great way to the lookout point Ackeburg / Selketalblick. The climb is steep, but the view and nature make up for it. Absolute recommendation.
