How long are the Vienna Woods?
The Vienna Woods are forested highlands that form the northeastern foothills of the Northern Limestone Alps in the states of Lower Austria and Vienna. The 45 kilometres (28 mi) long and 20–30 kilometres (12–19 mi) wide range of hills is heavily wooded and a popular recreation area with the Viennese.
The Vienna Woods are bounded by the rivers Triesting, Gölsen, Traisen and Danube, and are on the border of the Mostviertel and the Industrieviertel, two of the four quarters of Lower Austria. Reaching into the city of Vienna itself, they are a favourite outdoor destination for the densely populated area around the city.
