The municipality lies on the Hambach in the Hunsrück. The municipal area is 57.5% wooded.
Not far outside the village, to the west, is the Sauerbrunnen (“Sour Spring”), a health spring known for many centuries now, and still a popular spot for an outing. The minerals lend the drinkable springwater a flavour all its own, and many people come to drink it.

The German blazon reads: Unter rot-silbern geschachtem Schildhaupt in Blau ein goldenes Rechteck, darin zwei rotgewandete Figuren, die Aeskulap und Merkur darstellen.
The municipality's arms might in English heraldic language be described thus: Azure a block Or charged with figures of Aesculapius and Mercury of the same vested gules. the chief countercompony gules and argent.
The chief is a reference to the village's former allegiance to the “Hinder” County of Sponheim, which bore arms chequy gules and argent. Oberhambach was in the Sponheim Oberamt of Birkenfeld. The charge on the blue field is a simplified depiction of a Roman “eight-god stone” – now kept at the Birkenfeld local history museum – found near the Sauerbrunnen. Aesculapius especially supposedly refers to the spring, whose healing waters have been known for centuries.
