[Elias]: Beautiful walking trail just south of Jena. The walk through the Jagdanlage and Herzogstuhl is easy and the route is super greenish. The castle is closed as of now but one can walk across its verandah. (25/04/2021 )
[Andreas]: Long tour but totally worth it because you see peaceful villages and two castles and the hidden buildings in the forest: the Herzogstuhl, green house and the hunting facilities Rieseneck .
