Böhmerwald
In Austria, the Danube runs to the north of the Alps, separating it from the majority of the Bohemian Forest, although some small areas, such as the Dunkelsteiner Wald south of the Wachau, belong geologically to the Bohemian Forest despite being south of the Danube. The Vienna Woods near Vienna forms the north-eastern corner of the Alps, and here the Danube passes at its closest to the Alps (see Viennese Basin).
