Nature trail - "Gertrud Zetzmann" - Ohrdruf - Thuringian Forest

The route leads from Castle Ehrenstein along the Ohra and the mill channel to interesting and species-rich biotopes. A diverse plant and animal world can be admired in every season. Particularly impressive in spring is the bloom of the wood anemones in the princes' bushes or around the grass pond. There is always a lot to discover on the banks of the Ohra. This also applies to the area around the grass pond. Dippers and sometimes even kingfishers can be spotted. The grass pond is not only a fishing paradise but also a breeding and hunting ground for various water birds. The mill channel flowing alongside the path in sections was once the power artery for the early industrialization of the town. The technical monument Tobiashammer is a fully functional hammer mill from this early period.
