Umpfen-Berg, Mountain summit in Rhön, Germany

Umpfen is a 700.6 m high mountain in the Vordere Rhön, north of Kaltennordheim and west of Kaltenlengsfeld. On its western plateau lie the remains of Celtic ramparts, and on the western slope a former basalt quarry. A track from Kaltenlengsfeld leads past the Rhönbrise ski and hiking hut, which has a restaurant and dormitory, to a transmission mast and a circular path around the summit.

The western summit plateau holds remains of Celtic ramparts between 2,000 and 2,500 years old. Basalt was first quarried by hand around 1910; in 1914 Leimbach & Co. built a crushing plant on the Feldabahn, fed by a cableway from the Umpfen quarry. Soviet prisoners of war performed forced labour in the quarry during the Second World War. The quarry and plant closed in 1978 and the buildings were blown up.

The name Umpfen refers to the 700.6-metre summit above Kaltennordheim. On the western plateau, ramparts of a Celtic hillfort between 2,000 and 2,500 years old remain visible. The Rhönbrise ski and hiking hut, with its restaurant and bunk beds for walkers, stands near the top.

A farm track branches off at the Kaltenlengsfeld village community house and climbs to the Rhönbrise ski and hiking hut, which has a restaurant and a bed camp for hikers. From the hut a circular path passes a transmission mast and the rim of the former basalt quarry, with views over the upper Feldatal to Fischbach/Rhön and Diedorf. A second ascent leaves the circular path to the right towards Kaltennordheim, and the Dachstein viewpoint above the hut looks down on Kaltennordheim and Kaltensundheim.

The summit's western plateau holds the remains of Celtic ramparts between 2,000 and 2,500 years old, a detail many walkers pass without noticing. Below the former basalt quarry on the west side, Soviet prisoners of war were forced to work during the Second World War.
