The Falkenstein ridge (Kamm des Falkensteins) is a very small and not especially high subgroup on the northeast edge of the Allgäu Alps between Pfronten and Füssen. Locally it is called the Falkensteinkamm or even the Zirmgrat. The Vils river separates the subrange from the Tannheim Mountains. On the far side of the River Lech are the Ammergau Alps.
