The Falkenstein lies southeast of the small town of Tambach-Dietharz in Schmalwasser bottom (Schmalwassergrund) and is the most important rock formation in the Thuringian Forest in central Germany. It consists of porphyry. On the valley side, the crags are 96 metres (315 ft) high. Because of its situation on the side of a hill, it appears most striking when one stands immediately in front of it.
