3. Berlin, Germany
Travelers claim that the best part of Berlin is the nightlife. Pub crawls in the city are also a top pick for tourists. Aside from the Berlin Wall, Brandenburger Tor, Unter den Linden, many tourists drop by the Ampelmann stores, entirely dedicated to Ampelmann, the iconic traffic light men. The Holocaust Memorial, Holocaust Mahnmal, is also an incredibly unique location to visit in Berlin.
