Flights & getting there
Drivers coming from Berlin should take the A100 to the A115.
Regional trains leaving from Berlin Hauptbahnhof and Zoologischer Garten take about 25 minutes to reach Potsdam Hauptbahnhof; some continue on to Potsdam Charlottenhof and Potsdam Sanssouci, which are actually closer to Park Sanssouci. The S7 from central Berlin makes the trip in about 40 minutes. You need a ticket covering zones ABC (€3.40) for either service.
