 The Nagelfluhkette is one of the last higher elevations of the Alps before further north the Alpine foothills of the Allgäu begin.In the north lies the valley of the west-flowing Weißach; in the southeast the Hörnergruppe rises beyond the valley of the northeast-flowing Aubach.The Nagelfluhkette Nature Park is the first cross-border nature park to be created between Germany and Austria, thus representing an international natural protection pilot project.
