The Gleichberge are the most imposing witnesses to the Tertiary volcanic activity of the Heldburger Gangschar, which once ran from here to south of the River Main.
They lie southwest of the Werra valley, roughly east of the village of Römhild, on the northeastern perimeter of the Grabfeld country.
West and northwest of the Gleichberge are the Rhön Mountains, to the northeast and east is the Thuringian Forest, to the southeast lie the hills of the Lange Berge, to the south are the Haßberge Hills and to the southwest is the region of Grabfeld, to which the Gleichberge belong and of which they are its highest peaks.
Whilst the water of the Milz, which is fed by various headstreams on the eastern side of the saddle between the two mountains, flows towards the southwest via the Franconian Saale and Main into the Rhine, the short streams that rise on the extreme northeastern side of the Kleiner Gleichberg and the hills north of it drain via the Werra into the Weser.
The closely spaced mountains, kuppen and hills of the Gleichberge and its outliers include the following – sorted by height in metres (m) above Normalhöhennull (NHN)[1]:
