b. From Munich main station, take a (direct) train to Göppingen.
From Frankfurt Airport to Göppingen:
a. Go to the long-distance train station inside the airport (Frankfurt Flughafen Fernbahnhof).
b. At the ticket counter, ask for an ICE train ticket to Göppingen via Stuttgart. You will need to change trains in Stuttgart, and, depending on the train, possibly also in Mannheim.
c. Take a local train from Stuttgart main station to Göppingen.
From Stuttgart Airport to Göppingen:
a. Go to Stuttgart Main Station (Hauptbahnhof).
b.From Stuttgart main station, take a train to Göppingen.
2. Once in Göppingen you have two options:
a. Take a taxi to Ev. Akademie, Akademieweg 11, Bad Boll.
b. Take Bus 20 leaving from the central bus stop in Göppingen (5 minutes walking distance from the station). The bus takes you directly to the venue in about 30min. Exit at the stop called EV Akademie/Reha-Klinik, Boll.
