On foot
The city centre is not that large and most attractions are in a walkable distance from another.
By car
Those who want to drive in the city center should be aware that it is an "environment zone" similar to that found in many other large German cities. Cars are required to have a sticker declaring the car's pollution category.
By Local Transportation
The bus, tramway and subway network Map is operated by Rheinbahn AG. There is also a suburban railway network S-Bahn. Most destinations in Düsseldorf can be reached by local transportation. Tickets must be purchased and postmarked before using the transportation service. Tickets are bought from vending machines on the tram or subway stops. There are many different ticket types and the vending machine's instructions are only in German. To the average traveler, these three are the most relevant ticket types:
Short trip ticket Kurzstrecke: At 1.40 ⬠and valid for 30 min, about 4 stops on each vending machine there is a list telling where one can travel on a short trip ticket bought from that particular machine.
A-class ticket Preisstufe A: adequate to reach your destinations within Düsseldorf. A normal A-ticket costs 2.40⬠and is valid for 90 min.
Day ticket Preisstufe A / Tagesticket: costs 5.70⬠and is valid until 2am of the following day.
The tickets for areas B, C and D are for the suburban areas. In general these tickets are needed only if you are visiting someone living or working there; the main sights and establishments are all located in the A-area.
