Upper Danube Nature Park - Geography

Geography

Two small rivers, the Brigach and the Breg at the eastern border of the Black Forest unite at Donaueschingen to form the Danube.

The Danube passes through the Upper Danube Nature Park between Immendingen and Ertingen, its deep bed dug deep into the jurassic stone of the Swabian Alb. In this break-through valley of the still narrow river mighty rocks like chalk rocks ("Kalkfelsen") are exposed: One of it is the "Knopfmacherfelsen" at Beuron. Beuron with its Beuron Archabby lies in the middle of the attractive scenery of the nature reserve.

This break-through valley in the area of the Upper Danube is known as Danube Valley.

The upper part of the Danube passes through following cities: Tuttlingen, Mühlheim, Fridingen, Sigmaringen, Scheer and Mengen.

Geologically and touristically interesting are also the seepages of the Danube ("Donauversickerungen") in Immendingen and to the south of Fridingen.

Quite a number of forts and castles are sitting on top of numerous rocks on this stretch above the Danube. These are: Schloss Bronnen, Altwildenstein, Unterwildenstein, Wildensteiner Burg Hexenturm, Wildensteiner Burg Hahnenkamm, Burg Wildenstein, Schloss Werenwag, Schloss Gutenstein (Gutenstein), Ruine Dietfurt, Gebrochen Gutenstein, Hohenzollernschloss Sigmaringen, Schloss Bartelstein and Schloss Scheer.

In parallel with the Danube runs the Danube cycle track which leads from Donaueschingen to Vienna. The Danube valley railroad from Donaueschingen to Ulm enables the visit of the nature reserve by train. Beside regular trains, the so-called nature reserve express train operates during summer months, especially for visitors of the nature reserve between Tuttlingen and Sigmaringen.

Tributaries to the Danube within the nature reserve are: from the south the Ablach and the Ostrach, and from the north the Bära, the Schmeie (or Schmiecha) and the Lauchert.
