With a population of roughly 70 inhabitants, Mühlpfad is the district’s smallest municipality.

The municipality lies in the eastern Hunsrück 7 km south of Emmelshausen, right at the beginning of the Baybach valley.

[4] The German blazon reads: Geteilt durch einen grünen Leistenstab, oben in Silber ein blauer Mühlstein, begleitet rechts und links von einem roten senkrechtstehenden Mühleisen; unten in Gold ein blau gekrönter, -bewehrter und -gezungter, herschauender roter Löwe.

The municipality’s arms might in English heraldic language be described thus: Per fess a barrulet vert between argent a millstone azure between two millrynds palewise gules, the whole in fess, and Or a lion passant guardant, tail forked, of the fourth, armed, langued and crowned of the third.

The lion in the gold field refers to the village’s former allegiance to the Lower County of Katzenelnbogen.
