By train
The train route from Bonn Hauptbahnhof to Frankfurt is especially beautiful as it runs along the the rhine and you will see many old towns and castles on the way. It takes about 2 hours. If you are in a hurry, however, better take the fast train ICE from Siegburg as it takes only 50 minutes to Frankfurt.
By plane
The closest airport to Bonn is the Cologne-Bonn German: Köln-Bonn airport (http://www.koeln-bonn-air...) IATA: CGN, ICAO: EDDK. The airport handles far more air cargo traffic than passengers, but since the airport has become the hub for a few low-cost air carriers such as Germanwings (http://www.germanwings.com) and TUIfly (http://www.flytui.co.uk) the airport has seen a nearly two-fold rise in passenger traffic. Outside Europe the airport is a very well kept secret - airlines will often offer on par or better rates to CGN than some of Europe's larger airports like Gatwick, Heathrow, or Charles de Gaulle. Several flights from New York City cost as low as $400 round trip.
From the airport, take the SB60 airport bus â¬6.70 to Bonn's central bus station near the Hauptbahnhof. It leaves every 30 minutes from outside Terminal 1 arrivals. You can also take a train from the airport to Bonn-Beuel, which is on the other side of the river from Bonn city Zentrum. A taxi to central Bonn will cost around â¬45.
