The Long Rhön (German: Lange Rhön) is a ridge in the Central Rhön which forms part of the High Rhön within the Rhön Mountains. The Long Rhön is an elongated basalt plateau in the centre, roughly 800 metres above sea level, which is only occasional interrupted by mountain peaks. Its highest mountain is the Heidelstein (926 m above sea level (NHN)). A majority of the area is part of the Long Rhön Nature Reserve. In this area of the Rhön is the Black Moor.
