Arrival Information
Arriving from Frankfurt Airport
Coming from Frankfurt Airport it is strongly recommended to take a combination of train and taxi. The trip requires approx. 2.5 hours altogether. Take the direct train (40.90 Euro) from Frankfurt Airport (“Frankfurt(M) Flughafen Regionalbf”, regional train station) to Türkismühle (direction “Saarbrücken Hbf”). Tickets can be bought at the train station in the airport or on-line. It isn't possible to purchase tickets on the trains. Please note that Frankfurt airport has two train stations: the regional train station ("Frankfurt(M) Flughafen Regionalbf") and the long-distance train station ("Frankfurt(M) Flughafen Fernbf"). Take a taxi from Türkismühle to Dagstuhl (60 Euro). Make arrangements for the taxi at least three days in advance (further rates and contact details). The taxi company tries to organize shared rides with lower costs. Payment for taxis is often only possible in cash (in Euros). The participants list will be distributed prior to the workshop. People can then make contact to possibly share cabs or rental cars.
See the timetables from Frankfurt airport to Türkismühle with direct train connections for November 9, 2025: and for Türkismühle with direct train connections to Frankfurt airport on November 14th:
If you are familiar with public transport systems, don't mind waiting for the bus (waiting time of approx. 2 hours in St. Wendel), and would like to avoid the taxi fee, you can take this connection (train 43.30 Euro to St. Wendel, bus 9.30 Euro to Wadern). The bus ticket is available at the bus station or at the driver. See the website of the Deutsche Bahn for train and bus schedules. Use "Frankfurt(M) Flughafen Regionalbf" for Frankfurt Airport as start (station/stop) and "Wadern, Oktavie-Allee 1" for Dagstuhl as destination (address). Please make sure that you get into the correct bus (R2, direction Wadern ZOB) in St. Wendel. The bus driver stops on demand at the Dagstuhl institute. Then you can avoid the walk from the bus stop “Bahnhofstr. Dagstuhl, Wadern” to Dagstuhl (map).
