Berlin

Must-see historical sites include the Brandenburg Gate, the remnants of the Berlin Wall (East Side Gallery), Checkpoint Charlie, the Reichstag Building, and Museum Island.

The public transportation system in Berlin is excellent. The U-Bahn (subway), S-Bahn (overground train), trams, and buses provide easy access to all parts of the city. Walking and cycling are also great options.

Explore the East Side Gallery, visit the DDR Museum, wander through the charming streets of Prenzlauer Berg, visit the Berlin Cathedral, and experience the vibrant nightlife in areas like Friedrichshain.
