The train is the most convenient way to reach Karlsruhe from many locations in Europe. Connections can be checked on the Deutsche Bahn webpage where also tickets can be purchased. Karlsruhe’s main train station (Hauptbahnhof, Hbf) is centrally located, and within 25 minutes walking distance or 10 minutes tram ride to the venues. Many hotels are within easy walking distance, and there are taxis in front of the station. A public transport ticket (Sunday to Wednesday, Karlsruhe city) is included in the conference fee. You can find the ticket in the confirmation mail of your registration. Tickets for Saturday or Thursday can be bought from vending machines at the tram stops or online.
The best-connected major hub is Frankfurt International Airport (FRA) with a railway connection that brings you from the airport to the center of Karlsruhe in just a little more than one hour normally. However, there are major constructions works on the rails in September, which could cause longer and less convenient trips (bus + train, 1:45h). You might want to check the train connection and alternative airports below. Upon arrival at FRA, follow the signs to the long-distance train station (Fernbahnhof). We recommend booking tickets in advance by selecting "Frankfurt(M) Flughafen Fernbf" as Start and "Karlsruhe Hbf" as Destination. A one-way trip should cost approximately 44€ (excl. seat reservation). If you buy a "Flexpreis" ticket, you can use it for any train on that day. The cheaper tickets are only valid on the train you specified during booking.
A good alternative from many destinations is Stuttgart Airport (STR), which is best connected by bus (a little more than an hour, starting from 6€) or by train (1.5 hours, 35€). If you buy a "Flexpreis" ticket, you can use it for any train on that day. The cheaper tickets are only valid on the train you specified during booking.
The closest commercial airport is Karlsruhe / Baden-Baden airport, served by a limited number of airlines. Public transport brings you to Karlsruhe main station in around 1 hour (bus + train).
If you arrive by long-distance bus (e.g. from Stuttgart airport), walk through the main station (from south to north) to get on the tram or to get a taxi.
Parking within the city center is rather limited and expensive. If you should decide to bring your car, you may wish to pre-book a parking space at your hotel.
For free parking options, there is the big Messplatz square that can normally be used as park & ride. You can take the tram from Tullastr. to the inner city and your hotel. From the website there don't seem to be other eventy happening on that square at the time of the conference but we definitely recommend checking for any signs that might announce that parking is prohibited on certain days. Alternatively, you can use the free university parking or park on the curb of "Adenauerring" but you'll have to walk 700m to the next tram stop "Durlacher Tor".
A public transport ticket (Sunday to Wednesday, Karlsruhe City) is included in the conference fee. You can find the ticket in the confirmation mail of your registration. Google Maps is mostly accurate for walking and public transport options, the KVV local transportation website/app is sometimes more up to date and can also be used to purchase tickets. Alternatively, you can buy tickets at the vending machines at the major tram stops (cash and cards accepted) before boarding the tram.
