I am hopefully soon visiting Tiergarten Schønbrunn. This is a very good zoo, I have heard. It is the oldest in the world, and one of the best in Europe. I have a few questions about the zoo: 1. How long time would it take to see the zoo? I have heard it is pretty compact, but with many animal species. Is it possible to see the zoo and the rest of the Schønbrunn area in a day, even though the area is huge? 2. What rare and little known animal species among the general public, do the zoo have? Off course every one knows about the giant pandas and koalas. But they are not exactly little known. Are there any truely rare species there to look out for? 3. What are the biggest higlight areas in the zoo? Im interested in both older areas and newer ones.
