Cologne/Bonn International Airport (Köln/Bonn) is situated in the Cologne suburb of Porz, 15 km from Cologne and 16 km from Bonn. The second name of the airport is Konrad Adenauer Airport.
The official website of the airport is www.airport-cgn.de.
There is a railway station on the lower level of the terminal, so getting to major German cities is easy. Not only suburban trains but also high-speed trains to, for example, Stuttgart, Munich and Berlin pass through here.
From the airport to Cologne
When exiting the airport, you should keep to the following sign: a white letter S in a green circle. This is how the S-bahn – the railway – is marked in Germany.

Hint: The vending machines have a table below the data screen, in which each city is marked with its own code; enter the code using the numeric keys, then the ticket price appears on the screen.
