An excerpt from the article 48 facts about Vienna

There are 990 city parks there. Thanks to the Vienna Forest complex and the Danube area, almost half of Vienna’s total area is green (the greenest district is Hietzing, where about 70 percent of its area is green). These green areas consist of meadows, parks, vineyards, forests, fields, and gardens. From the city center, you can reach the nearest recreational areas (such as Danube Island) in 15 minutes.
