The Thuringian Forest Nature Park extends over the area around the Rennsteig in the Thuringian Forest, in the High Thuringian Slate Mountains with the Schwarzatal and on the western flank of the Franconian Forest between Eisenach in the northwest and Sonneberg in the southeast.
It includes, among other things, the so-called dam region around the Old Gotha Dam (also called the Tambach-Dietharz Dam), the Schmalwasser, the Ohra and the Lütsche Dams, the Erletor Dam, the Schönbrunn Dam at the transition from the Thuringian Forest to the Slate Mountains, but also the Schwarzatal with the Scheibe-Alsbach Dam and the Goldisthal pumped storage power station and the Lichtetal with the Leibis-Lichte drinking water dam.
The 170 km² Vessertal-Thuringian Forest Biosphere Reserve is enclosed by the nature park. The highest peaks in the Thuringian Forest Nature Park are the Großer Beerberg (982 m above sea level) and the Schneekopf (978 m above sea level). The Großer Farmdenkopf in the Thuringian Slate Mountains reaches 869 m above sea level, and the mountain peaks Kieferle (867 m above sea level) and Bleßberg (865 m above sea level) are almost as high. The Thuringian Forest Nature Park borders the Franconian Forest and Thuringian Slate Mountains-Upper Saale Nature Parks. Together, the three nature parks form a closed nature park area of approximately 4,000 km².
