Exit the ubahn (subway) in the direction of 1972 Olympiadorf. At the exit there is a small green area with a fountain. Your guide will be waiting for you here. If you are arriving by taxi, have them drop you at the taxi rank on Helene-Mayer-Ring, alight and walk up the stairs to the fountain.
This tour will end inside the museum with free time to continue exploring after the guide leaves. Public transport and taxis are available outside the entrance.
