Eichkogel, Mountain summit in the Vienna Woods, Liesing, Vienna, Austria

Eichkogel rises to 428 meters within the Vienna Woods and displays limestone formations from the Jurassic and Cretaceous periods. The slopes show different rock layers that become visible during walks through the area.

Eichkogel is the highest mountain in Vienna's 23rd district, Liesing, reaching 428 metres in the far south-west of the city at Rodaun. It lies within the Vienna Woods, part of the Northern Limestone Alps, and is bordered on three sides by Lower Austria. Its wooded summit consists of light grey limestone from the Upper Jurassic and Lower Cretaceous. It is not the same as the Eichkogel several kilometres further south in Lower Austria.

The mountain is part of a protected nature area that shelters rare plants like Diptam and Spring adonis. Visitors notice the variety of forest vegetation during walks and see how this place is actively protected.

The summit lies in the far southwest of Vienna, in Rodaun, surrounded on three sides by Lower Austria. The Wiener Graben forms the border with Kaltenleutgeben at its southwestern foot, and the Dürre Liesing flows through the Kaltenleutgebner valley along the Kaltenleutgebener Bahn line. Approach from the Rodaun side.

The former cement plant on the southeastern slope, in the Kaltenleutgebner valley, processed limestone quarried at the neighbouring Teufelstein. The Dürre Liesing flows through this valley alongside the Kaltenleutgebener Bahn line. The Eichkogel is not the same as the mountain of the same name a few kilometres further south in Lower Austria.
