 Schönbuch Nature Park is an almost completely wooded part of the Swabian terraced landscape between the Black Forest and the Swabian Jura.The giant steps of the Schönbuch are formed by alternating strata of sandstone and clay which have eroded at different speeds.The hard Keuper mountains rise up from the agricultural land of the Gäu plain to the west, forming the characteristic southern edge of the Schönbuch with their hard sandstones.
