Research Institute for Discrete Mathematics

How to Reach the Institute

Deutsche Version | Home page of the institute

The institute is in the same building as the Arithmeum. It is located in the centre of Bonn, at the southern corner of the Hofgarten park, only a few hundred metres from Bonn Hbf (main station) and the downtown pedestrian precinct. It is easy to reach by train, by car and by airplane.

• Arriving by train

  From Bonn Hbf (main station), it is a 5-minute walk: go to the bus station (ZOB) next to platform 1, then cross Kaiserplatz and walk along Am Hofgarten until you reach the institute (the red building marked "Arithmeum" on this map). There are signs which point you to the Arithmeum.
  To find out about schedules of national and international trains to Bonn Hbf, use the DB timetable query page.

• Arriving by car

  Please note: drivers are strongly recommended to leave their car in one of the public car parks (marked "P" on the map). The "Universität" car park is close to the institute; it is located at the northern corner of the Hofgarten park and can be accessed from Adenauerallee.

  • If you approach Bonn from the north (from Köln, Düsseldorf etc.) via the A555 or A565 motorways: follow Bonn-Zentrum. At the Verteilerkreis Bonn (Potsdamer Platz), take the second roundabout exit and follow Heinrich-Böll-Ring, which will be renamed to Thomastraße. After 1km, you will have to turn left into Am Alten Friedhof (left edge of this map). Follow Berliner Platz and Oxfordstraße. At the end of Bertha-von-Suttner-Platz, make a right turn into Belderberg (B9). After passing under a baroque building (Koblenzer Tor), you are on Adenauerallee, from where you can immediately make a right turn into Stockenstraße to access the "Universität" car park. (To reach the institute building itself, take the next right turn instead, which is Am Hofgarten.)

  • Otherwise, if you approach Bonn via the A562 motorway, take the very last exit (named Bonn-Zentrum), then make a right turn into Friedrich-Ebert-Allee (B9). Follow this road for 4km (it is renamed Willy-Brandt-Allee and then Adenauerallee). Before you would pass under the baroque gate (Koblenzer Tor), turn left into Stockenstraße to access the "Universität" car park. (To reach the institute building itself, take the previous left turn instead, which is Am Hofgarten.)

• Arriving by plane

  • From Köln/Bonn Airport (CGN):
    You can take the SB60 shuttle bus outside the arrivals terminal, which brings you to Bonn Hbf (main station) in half an hour. Note that this service has a special fare (approximately 9€ for a single ride) different from that of most other local public transport lines. To search for more connections, use the DB timetable query page.
    A taxi from the airport to downtown Bonn or vice versa costs about 70€.
    The car ride is about 22km or 20 minutes (assuming free-flowing traffic).

  • From Düsseldorf Airport (DUS):
    The airport railway station (Bahnhof Düsseldorf Flughafen) is about 3km from the terminal (D-Flughafen Terminal A/B/C). You can reach it by the SkyTrain. suspension train (Schwebebahn) in 5 minutes. Note that this service might not be included in your flight or train ticket, in which case you can buy a "Kurzstrecke" ticket from a vending machine (more information here). Alternatively, the S7 regional train, which does not stop at the airport railway station, takes you from the terminal via other intermediate stops to Düsseldorf main station (Düsseldorf Hbf) in 12 minutes. From either the airport railway station or Düsseldorf main station, take a connecting train to Bonn Hbf (main station). The entire ride to Bonn takes about 65 minutes. To search for connections and fares, use the DB timetable query page.
    If you come by car, first follow the direction Köln, then Flughafen Köln/Bonn, then Bonn.

  • From Frankfurt(M) Airport (FRA):
    There are several intercity links from the airport railway station (Frankfurt Flughafen Fernbahnhof) to Bonn Hbf (main station), including direct trains. Additionally, there are fast ICE (intercity express) trains to Siegburg/Bonn station, from where tram line 66 takes you to downtown Bonn in 25 minutes. (Get off the streetcar at Universität/Markt, which is just one stop after Bonn Hbf, take the "Kreuzkirche/Kaiserplatz" exit to leave the underground station, then turn left at street level, following the signs to the Arithmeum.)
    The trip from Frankfurt takes between 70 and 100 minutes. To search for connections and fares, use the DB timetable query page.
    If you come by car, first follow the direction Köln and then Bonn.
