The Wienerwald (Vienna Woods), also called the green lung of the city, is a huge climb west of Vienna. Actually mostly belonging to Niederösterreich, its foothills also form the landscape of the western outer districts.
When you walk along any outbound arterial road there, you sooner or later will find yourself in the Wienerwald. In case you prefer to abbreviate this experience I recommend you visit Pötzleinsdorfer Schlosspark.
The main entrance is right next to the final station “Pötzleinsdorf” of tram line 41. This park originally belonged to Pötzleinsdorf Palace, which still exists there, currently used as a school, and in contrast to the park is not open to the public.
The park itself was laid out in the 18th century in a romantic English style, enhanced with lots of monuments, wayside shrines, and other decorative lithic constructions. Some of them remained till this day. Present there are also street-soccer grounds, vivariums housing local animal species and other leisure facilities, but they are all located close to the entrance.
The more you move away from the entrance the more the park merges into Wienerwald. First you leave these facilities behind, then the decorative elements become less and less, and instead of the intentionally planted rare sorts of trees, you will face the naturally grown typical mixed forest.
Being engrossed in thoughts or talks you easily won’t even realise at which point it changes from a proper park to the wild. I love this soft transition from man-made to nature-made environment.
