The Rheingau Mountains or Rheingau Hills form the westernmost section of the High Taunus and extend for 20 kilometres in a south-west to north-east direction between the Rhine valley near Lorch and Assmannshausen in the west and the Walluf valley near Schlangenbad in the east.
[1] The Rheinhöhenweg Trail on the right bank of the Rhine runs along the ridgeline of the mountains which are part of the main crest of the Taunus.
The centre of the Rheingau Mountains is formed by the ridge line from the Kalter Herberge to the 580p-metre-high Erbacher Kopf.
About one kilometre southeast of the Kalter Herberge, and thus in front of the ridge line, the Hallgarter Zange also reaches a height of 580 meters.
[2] Due to its south-facing location, the Hallgarter Zange appears from the Rhine as the highest elevation and partially covers the Kalte Herberge.
