Karlsruhe has three handy airports nearby (as well as the airports in Basel and Strasbourg):

Frankfurt Airport

The Frankfurt Airport is Germany's busiest airport. It serves most international destinations and is relatively easy to access from Karlsruhe.

The ICE high speed train from Karlsruhe main station leaves every half hour. You can travel either directly and non stop into Terminal 1 (Lufthansa Terminal) or change at Mannheim. Travel time is about one hour.

If you plan ahead you can reserve long-stay vacation parking at Frankfurt Airport via this link.  Be sure to read the fine-print though.

If you don't live that close to the train station, special airport taxis (Flughafenzubringer) can pick you up at home and meet your flights at the airport. It is sometimes the most convenient option and is often supported for business travel.

Don't confuse Frankfurt Airport with Frankfurt-Hahn Airport — the two are nowhere near each other.

Karlsruhe Baden Airpark — is only 40 km from Karlsruhe. The airport is used by Ryanair and Air Berlin.  You can drive or go by tram/bus or private coach from the main Karlsruhe train station (Hauptbahnhof).

Information about public transportation between the Baden-Baden train/bus station and the airpark is available on the airport's website. Be sure to read your timetable carefully before you make your plans, as they do not always seem logical.

Stuttgart Airport -—1.5 hours from Karlsruhe by train. Train passengers from Karlsruhe must change at Stuttgart main station.


As an alternative to air travel...

Karlsruhe to Paris via Strasbourg on the TGV takes just 3 hours!.

London can be reached in 7 to 8 hours by train and if you plan ahead and don't travel during busy times, it can be relatively cheap.
