Location

Heidenrod lies in the western Taunus north of the main ridge and west of the Aar, between Koblenz and Wiesbaden, roughly halfway between the Rhine and the Lahn. The municipal area stretches east and west of the high ridge along which runs Bundesstraße 260, also known as the Bäderstraße (“Bath Road”). The two highest settlements in the western Taunus, Kemel (village centre, 510 m above sea level) and Mappershain (village centre, 500 m above sea level) are Heidenrod municipal districts. The Mappershainer Kopf, some 500 m northwest of its namesake place, is at 548 m above sea level the highest mountain in the Western Hintertaunus ("Farther Taunus").^{[3][circular reference]}

Within municipal limits, west of the municipal district of Kemel, rise the headwaters of the Wisper, which run together between the constituent communities of Wisper and Geroldstein. In the constituent community of Mappershain rises the Dörsbach. Some 60% of the municipal area is wooded.
