The short answer: very green. It's just one of the reasons why Austria's capital tops the list of most livable cities nine years running. Vienna is a place you can experience it all: Stroll through bustling downtown Vienna, marvel at the splendid Imperial buildings or the modern architecture, and relax under ancient shady trees while listening to melodic bird song.
In addition to Vienna’s well-known parks there are still a number of hidden treasures to be discovered. For example, if you can't get enough of Gustav Klimt's landscape paintings in the Belvedere Palace's permanent exhibition, you should experience your own green wonder only a few steps away at the Botanical Gardens next to Belvedere Palace. Over 11,000 plant species from six continents are tended and cultivated here.
If you're hungry for even more nature, just hop on the underground and ride it for a mere ten minutes to the city’s biggest green space. The Prater boasts some extensive fields and woods. The 2.8 mile-long (4.5-kilometre-long) Hauptallee is lined with some 2,500 trees. If you simply turn off the main boulevard and wander into the narrow, wooded paths you'll be surrounded by breathtaking nature, amidst a number of small clearnings and ponds.
Carry on for just two more subway stops to encounter yet another natural paradise in the city. The Alte Donau ("Old Danube") is a popular destination for anyone who wants to enjoy a snack or a cool drink right on the water while watching the sailboats execute their tacks and jibes – and all in front of the futuristic backdrop of the Donau City business district.
