S+U -Bahnhof Zoologischer Garten is one of very historical station in Berlin. It could take you to…read moreone of the most popular side of Berlin. Beside the Berlin zoo, there are also got many cool shops and malls around, it simply made it a great area to shop, you can also go from here to the Tiergarten, to have yourself a walk or a bicycle trip.
The station itself it quite big, there are come shops and restaurants inside as well. So no worries, if you are in hurry and hungry. It got information board everywhere to help the passengers better to find their way to the right train, the station itself is a city to city station. So it quite easy to get lost, just follow the signs on the wall.
If you just want to have a short trip to Potsdam, you can take RE7, which usually it will stop at platform 3 or 4. Also work with S7, which at platform 6. Don't forget to get a ticket for C area first and valid it. You can also take the S-Bahn here back the Berlin main railway station (Berlin Hauptbahnhof). It got quite a big bus station outside as well. It's very convenient.
The U-Bahn system of here does system a bit messy. For example, the U2 line, if you want to get to the other side, you have to go up and down for this, it really took some time away. For the people who in hurry, that's really a horrible experience. I hope, they can make it much more convenient for the passengers. U1, U2 and U9 are the available line that could switch here.
