Wackerstein mit Höhle, Limestone rock formation with cave in Pfullingen, Germany.

Wackerstein is a Weißjura limestone rock formation on the Swabian Alb near Pfullingen, reaching about 825 m above sea level. The rock and its hilltop are linked to the Albtrauf only by a narrow ridge and otherwise stand free. It is protected as a geotope and natural monument, together with a cave.

The formation originated as a reef during the Jurassic period when the region was covered by sea. Through geological processes over millions of years, this reef became the limestone structure visible today.

The name Wackerstein refers to the rock itself, which stands free of the Albtrauf and is linked to it only by a narrow ridge. The rock and the adjoining hilltop are protected as the geotope and natural monument "Wackerstein mit Höhle", roughly 2700 metres west of Unterhausen. The hiking trail Hochgehtürmt of the Hochgehberge region passes the rock as an intermediate stop.

The rock and the nearby barbecue area with shelter hut are reachable only on foot. Two approaches exist: from the path junction at the Hinteres Sättele below the Schönberg, or along the narrow ridge from the Won on the Alb plateau. The Wackerstein is an intermediate stop on the Hochgehtürmt trail of the Hochgehberge hiking region.

The rock and its hilltop are linked to the Albtrauf only by a narrow ridge and otherwise stand free. The Weißjura rock is a former reef of the Jurassic Sea, and the whole group with its cave is protected as a geotope and natural monument, roughly 2,700 m west of Unterhausen.
