For all Berlin visitors who would still like to look around in Potsdam and Sanssouci. For the journey to Potsdam offers the German Railways regional trains every 30 min. of tact which need only 30 min. to Potsdam city. Because the historical Old Town of Potsdam can be crossed comfortably by feet on the way in the garden Sanssouci. Both is „UNESCO world cultural heritage“, the huge expansion of the Sanssouci garden landscape offers numerous historical buildings between which a relaxed walk can be arranged. (I´m owner of a valid Sanssouci Garden Tour License), e.g., Chinese Teahouse, Big Orangery Castle, Dragon's House (with restaurant), Belvedere on the Klaus's mountain, the great New Palace, Castle Charlottenhof and of course Castle Sanssouci. The way back must not been done by feet, at the rear end of the garden there is a bus stop which brings us back to the central station Potsdam.
