Getting there & away
S-Bahn line S7 links central Berlin with Potsdam Hauptbahnhof about every 10 minutes. Regional (RB/RE) trains leaving from Berlin-Hauptbahnhof, Berlin-Zoo and Berlin-Charlottenburg are faster; some also stop at Potsdam-Charlottenhof and Potsdam-Sanssouci, which are closer to Park Sanssouci than Hauptbahnhof. There’s also an hourly RB train to Berlin-Schönefeld airport. Berlin transit passes must cover Zones A, B and C (€2.60) to be valid for the trip to Potsdam.
Drivers coming from Berlin should take the A100 to the A115.
