Public Bus 100 is an easy and cheap way to see Berlin’s top sights including the Reichstag, Brandenburg Gate, Unter den Linden, and the UNESCO World Cultural Heritage listed Museum Island.
Berlin is very flat and thus great for exploring on foot. However, at nine times the size of Paris, Berlin’s excellent public transportation system is a great help when exploring the city. Berlin uses double-decker buses and for visitors, Berlin bus line 100 and bus line 200 are great ways to see the major sights cheaply. Bus 100 and bus 200 pass directly in front of top sites or are within easy walking distance of the best-known sights in central Berlin. Visitors with a cheap transportation card, may enjoy taking bus 100 all the way to its terminus and then return to sights that are of particular interest. Otherwise, bus 100 requires a standard Berlin AB ticket — €3.
At the far end of Unter den Linden are several classical buildings including those of the Humboldt University (former students include Marx, Engels, and Lenin, while Einstein taught here), the German National Opera (one of three opera houses in Berlin), and the New Guard (Germany’s official memorial for the victims of war and tyranny). The late 17th-century Zeughaus (Armory) is the oldest building on the boulevard and suitably houses the very interesting and comprehensive German Historical Museum. Its ultra-modern IM Pei-designed annex has excellent temporary exhibitions.
Bus 100 now enters Museum Island in the Spree River. Museumsinsel is a UNESCO World Cultural Heritage site with some of the finest museums in the world. The most popular are the Pergamon and Neues Museum. Despite its Renaissance appearance, the Berliner Dom (Cathedral) is just over a century old. The former Prussian Palace (Berliner Schloss) was rebuilt and opened in 2021 as the Humboldtforum with the ethnological and Asian art collections and several futher major temporary exhibitions.
After about half an hour, bus 100’s journey ends at Alexanderplatz, a huge square that was the heart of East Berlin during the communist years. It is once again lively but mostly due to its important transportation hub and large shopping centers where Berliners outnumber tourists by far.
Bus 100 returns to Zoologischer Garten after a brief stop making now a good time to grab the front seats on the top deck for the best views. Alternatively, change to Bus 200 and follow a slightly different route via Potsdamer Platz and Kulturforum back to Zoologischer Garten.
