Original Berlin Walks

Whether your interests lie in Nazi or Cold War history, Queer Berlin, Jewish life, or even Berlin's famous Christmas Markets, Original Berlin Walks have something for everybody.  Their friendly expert guides create a wonderful walking tour experience where, depending on the tour, you will also take advantage of Berlin's fantastic public transport system.  Tickets are very reasonably priced and if you book on their website in advance they often give a discount.
During the winter months they operate on a reduced schedule - check out their website for up to date information.

Most of their tours operate in Berlin but they also run tours to the nearby city of Potsdam, and the Sachsenhausen concentration camp memorial near Oranienburg.
