Travel Information

Flying to COLOGNE (CGN) Airport
 
The most convenient airport to arrive at is the Köln-Bonn Flughafen, known internationally simply as Cologne(CGN).
 http://www.airport-cgn.de
 
There are many direct flights from European cities, especially from budget airlines (EasyJet, GermanWings, TUIfly, Air Berlin...) but also from Lufthansa and other national carriers. There is a BUS service (line 670) to the Bonn Central Railway Station (Bonn "Hauptbahnhof" or "Hbf") leaving from outside the terminal building, roughly every 30 mins (this varies with time of day and day of the week). From March 2007 the bus only leaves from stand D (Terminal 2).

There is a more frequent (and faster) ICE train service to Siegburg (38 mins) from which there is a direct connection by TRAM ("S-Bahn") line 66 to Bonn Hbf (25 mins). A single tram ticket costs EUR 4.10 (see below)

Note that Ryanair does not fly to Frankfurt Airport (FRA) but to Frankfurt-Hahn (HHN). Although there are many cheap flights, this airport is a 2 hour drive from Bonn and very poorly connected by public transport.
From BONN (Hbf) to the hotels and the MPIfR
 
The Bonn Central Railway Station (Bonn Hbf) is the main transport interchange point. There are frequent trains to Bonn from many cities all over Germany and neighbouring countries.
