Make your way to the Zoologischer Garten train station or Hackescher Markt train station to meet your guide. You will need a Berlin Transport ABC Zone ticket. Relax and enjoy the scenery on the ride to Oranienburg, which takes about 45 minutes.
Arrive at the Sachsenhausen Memorial and Museum, where you'll have pre-purchased entrance fees included with your tour. Follow your guide, who will fill you in on the history of the camp, where 200,000 people were imprisoned between the years of 1936 and 1945.
Visit the burial pits, gallows, gas chambers, and punishment cells located inside the prison. Hear stories of prisoner bravery as well as the atrocities that took place at the camp, which now serves as a national memorial to the prisoners who lived and died here.
At the conclusion of your tour, return to Berlin the way you came.
