Navigating Berlin is remarkably easy thanks to its world-class public transport network, which is efficient, extensive, and relatively affordable. The system is divided between the U-Bahn (underground subway), distinguishable by its bright yellow trains, and the S-Bahn (suburban railway), which operates on elevated tracks and connects the city center with the outer suburbs. The S-Bahn also features the famous "Ringbahn," a circular line that loops around the inner city and serves as a helpful orientation marker for visitors. Together, these trains form the backbone of local travel, allowing you to cross the metropolis quickly.
Complementing the rail network are trams, buses, and ferries. The tram system (Straßenbahn) is primarily found in the eastern districts, a historical quirk from the city's divided past, and offers a scenic way to explore neighborhoods like Prenzlauer Berg and Friedrichshain. The bus network covers every corner of the city that trains don't reach. A favorite among tourists is the Bus 100, a double-decker line that passes many major landmarks, including the Reichstag and Brandenburg Gate, effectively serving as a budget-friendly sightseeing tour. Additionally, public ferries traverse the city's lakes and rivers, and they are fully integrated into the standard ticketing system.
The city is divided into three tariff zones: Zone A covers the city center inside the Ringbahn, Zone B extends to the city limits, and Zone C includes the surrounding area, such as Potsdam and Berlin Brandenburg Airport. Tourists typically need an AB ticket for general sightseeing or an ABC ticket if they plan to travel to the airport or visit palaces outside the city. You can purchase a "Kurzstrecke" (short trip) ticket for journeys of up to three train stops or six bus/tram stops, which is a cheaper option for quick hops. For those planning a full day of exploration, a 24-hour ticket is often the most economical choice.
Tickets can be purchased at multilingual yellow vending machines located on station platforms, or via mobile apps like BVG Fahrinfo and Jelbi, which are highly recommended for convenience. If you buy a physical paper ticket, you must remember the most important rule of Berlin transport: validate your ticket before your journey. Look for the small yellow or red stamping boxes on train platforms or inside buses and trams. Failure to stamp your ticket can result in a fine of 60 Euros, even if you have purchased one. For visitors, the Berlin WelcomeCard is a popular option, offering unlimited travel alongside discounts for museums and attractions.
Public transport operates generously, with most lines running from roughly 4:00 AM until 1:00 AM on weekdays. In the intervening night hours, an extensive network of Night Buses (marked with an "N") replaces the train routes. On weekends (Friday and Saturday nights), the U-Bahn and S-Bahn run 24 hours a day, ensuring that the city's vibrant nightlife is always accessible. This round-the-clock service makes getting home safe and easy, no matter how late you stay out.
If you prefer alternatives to mass transit, the city is extremely bike-friendly. You will find dedicated cycling lanes on most major streets, and bike-sharing services like Nextbike, Lime, or various e-scooter providers are ubiquitous; you can simply unlock them with a smartphone app. Taxis are cream-colored and can be hailed on the street or found at designated stands, though they are more expensive than in many other European cities. Ride-hailing apps like Uber, Bolt, and Freenow are also widely available and often offer a slightly cheaper alternative to traditional taxis.
For a unique experience, take a ride on the U1 line, the oldest part of the subway network. Much of this line runs on an elevated viaduct through the heart of Kreuzberg, crossing the stunning Oberbaum Bridge and offering picturesque views of the Spree River and the urban skyline. Whether you are rushing to a museum or leisurely crossing the city, the transport system is not just a utility but an integral part of the Berlin experience.
