This GeoRoute begins at the Old Observatory (Alte Sternwarte) on the Kleiner Seeberg near the south-eastern outskirts of Gotha. The route passes over the Grosser Seeberg hill (nature reserve), which is famous for the very special 220 million year old sandstone that is found here. The Seeberg Sandstein has been used in many important buildings such as Erfurt Cathedral. At the Düppel (lookout and traditional country inn on the Seeberg) one can see the reddish-grey, sparsely vegetated Badlands, which are also found on the south slope of all three castle hills. The Seeberg Route not only takes you past geological and archaeological sites but also historically important places such as the Bach family residence in Wechmar. As the trail continues it passes a former water castle (today an Infocentre for Regional History and Geology) in Günthersleben, old mills and historic water channels. The Seeberg Route shares some sections with the Luther Route, the Graf-Gleichen-Trail and the Nature Trail Apfelstädt-Mühlen.
