Kissel, Mountain summit in Thuringia, Germany.

Kissel is a hill in Thuringia that reaches approximately 649 meters and offers several hiking routes winding through forests and past rock outcrops. Multiple paths from different directions converge at the summit, allowing walkers to choose their preferred route through the wooded terrain.

The summit forms part of the Thuringian Forest range, which has naturally separated different German territories since medieval times. This strategic location made the forest zone an important geographical boundary that shaped regional divisions for centuries.

The name Kissel may refer to the hard porphyry rock found here, and a mountain called Kyselinge appears in a 1330 boundary description tied to the Frankensteiner sale document. Near the summit stands the listed Jagd- und Forsthaus Kissel, built in log-house style in 1868/69 for the Meiningen dukes.

Access to the Kissel area is via the Waldhaus Kissel junction on Landesstraße 1126, about 1500 m west of Schweina. The Pummpälzweg long-distance trail from the Wartburg to Bad Salzungen passes by the mountain. The summit lies roughly 1600 m south of the Rühler Häuschen on the Rennsteig, and the Arnsberg secondary peak adjoins to the southeast.

The name Kissel may derive from the hard porphyry rock found here, and a mountain called Kyselinge is recorded in a 1330 boundary description tied to the Frankensteiner sale deed.
