All city tour boats start from Friedrichstraße, Nikolaiviertel, or Alte Borse, however, Berlin sightseeing cruises have multiple boarding points scattered throughout the River Spree. You can board your cruise from Friedrichstraße, Liegestelle Seminarschiff, Janowitzbrucke, or the Caprivi Bridge. The Berlin Lake cruises, which sail across 7 lakes in the city or go towards the Muggelsee Lake start from Anlegestelle Wannsee or the Treptow Harbor. You can choose a boat tour depending on your nearest boarding point or the kind of route you want to take.
