I will be in Berlin for the umpteenth time for the week beginning Monday 28 November. Having already seen most of what Berlin has to offer, I am wondering if there is anything of interest towards the end of the U- and S-Bahn lines. In this vain, I have already been to Potsdam, Spandau, Alt-Tegel, Oranienburg, Rathaus Steglitz, Osloer Straße, Uhlandstraße, Warschauer Straße, Wannsee, and naturally, both ends of the U55, namely Hauptbahnhof and Brandenburger Tor, and, although not at the end of the line, Köpenick.
Do any of the other end of line stations have something of interest in their vicinity? I am thinking perhaps of going to Henningsdorf or Ahrensfelde or Bernau or Pankow. Maybe you can offer some advice on places of interest.
Thank you in advance.
