After coming out of FREUD MUSEUM take the 38th road to GRINGZING, and then change to 38A straight up Kahlenberg. Although the weather is very cold, I think it is worth going up and seeing. From there you can see the panoramic view of Vienna and Hungary, although I don't know where Hungary is at the bottom. Sitting on the top of the mountain drinking coffee and watching the panoramic view, it feels really good. On the way from Vienna to the Karen Mountain Observation Deck, you will pass by Greenjin Town. You must go for a walk, see, eat and drink. This is a place for new wine. If you see a pine branch hanging on the door of a winery, it means that he has new wine. Go in and sit down, and you can feel how Austrians live. There are beautiful songs, sweet wines and happy people.
