The most convenient airport is Frankfurt (FRA). Further possible airports are Zürich (ZRH), Strasbourg (SXB), Basel-Mulhouse-Freiburg (BSL), Stuttgart (STR), and Karlsruhe/Baden-Baden (FKB).

Arriving by train

InterCity trains usually stop at Offenburg, in the south-west of Germany, and sometimes even at Hausach. Trains from Offenburg to Hausach or even to Wolfach run quite frequently. Do not mix up Hausach with Haslach. Do not get off the train at Haslach!

The current timetable is available at German Railways (Deutsche Bahn AG). The input "Wolfach" is said to be ambiguous by mistake. Just click on "Search connection" once again without making any changes. These pages contain a ticket service.

Coming from Strasbourg, you may buy a ticket "Europass 24h" valid 24 hours in Strasbourg and Ortenau (so, including Hausach, Wolfach, Oberwolfach) for local trains and busses. The ticket can be purchased at the railway station or at any automaton in bus/tram stations in Strasbourg, see: Europass and Europass-24h. These tickets can also be bought in any bus, at any railway station in Ortenau.

Information for electric car drivers

At the parking lot of the MFO you will find a charging station. The double box with 2 x 11 kW AC can charge two cars simultaneously. Depending on the type of vehicle and the battery size the charging will take 1.5 to 3 hours for a range of 100 km. Please come to the reception to obtain an RFID charging card and afterwards to pay your bill.


The Institute will offer free taxi transfer from the train station in Hausach to the Institute on Sunday evening at the following fixed times:

5:30 pm at Hausach (with stop 5:40 pm at Wolfach train station)
6:30 pm at Hausach (with stop 6:40 pm at Wolfach train station)

The taxis will wait directly in front of the station building in Hausach (or next to the station platform in Wolfach) and will display a sign "MFO". 

For the return trip we will organize car pools from Oberwolfach to the train stations in Wolfach and Hausach. For three groups we will also cover the taxi fare. 

Taxi fares at other times cannot be reimbursed, unfortunately. We recommend to carry some cash with you, since in our very rural area credit cards are sometimes not accepted.

Usually, taxis are waiting in front of the train station in Hausach and they run until midnight on Sundays.

The phone numbers of our local taxi companies are as follows:

• Taxi Heizmann +49 (0) 7834 333

A standard taxi from the railway station to the Institute costs about 42 EUR from Hausach (12 km) and about 30 EUR from Wolfach (7 km). Large taxis which are able to carry more than 4 persons cost about 57 EUR from Hausach and about 42 EUR from Wolfach.


Local timetables including buses and trains can also be searched. To find the bus from Wolfach Station to the Institute you would enter as starting point Wolfach, Stop: Railway Station, and as destination Oberwolfach, Stop: Walke.

Other stops like Stuttgart Airport (i.e. Flughafen) are possible. Due to the infrequency of the local bus service it is advisable to search the long distance and the local bus separately.
