Wiesbaden

Once you are in the city centre it's pretty comfortable to just walk around. There's a main pedestrian area Fußgängerzone which is similar to an open-air mall, but more relaxed. Shops line the street and alleys, and it's mostly closed off to cars. Many shops, cafes and restaurants can be found in this area. Be sure to walk around the "Old City" Altstadt as well.

If you want to go further out of the city centre, you can use the developed bus system. Buses travel frequently and on time. It is possible to buy tickets on the bus, just ask the driver because of possible language barrier issues, just say the name of the street you want to go to. Your trip will cost you a minimum of €1.55 adult, but probably no more than €2.50 one way. There's also a one day ticket, with which you can go wherever you want, available at the ticket machines for €5.90 and €3.50 for adults and children, respectively. Weekly tickets are available for €20.60, and have the added bonus of one other adult and all of your own children up to 14 y.o. travelling for free from 7PM weeknights, and all day Saturday and Sunday and public holidays.
