Lainzer Tiergarten

At 25 sq km, the Lainzer "Zoo" is the largest (and wildest) of Vienna’s city parks. The former hunting ground of Ferdinand I, over 80% of it is covered in woodland. Take in the view from Hubertus-Warte, a six-story-high viewing platform on top of Kaltbründlberg (508m above sea level) or scout for the park’s animal population, from deer and wild boar, to woodpeckers and squirrels.
