The Wasserkuppe is a mountain within the German state of Hesse. It is a large plateau formation at an elevation of 950 metres (3,120 ft) and is the highest peak in the Rhön Mountains. Great advances in sailplane development took place on the mountain during the interwar period, driven by annual contests. Near the summit there is still an airfield used by gliding clubs and pilots of light aircraft.
