Berlin is huge, and you can't get by without public transport — 2 sights of interest are often 5 km apart. The network covers the U-Bahn metro, the S-Bahn suburban railway, trams in the eastern part of the city, and buses, all under a single fare system split into zones A, B and C. Visitors need zone AB at €3.80, or zone ABC at €4.70 for the airport. A day ticket for AB costs around €10 and pays for itself from the third ride. Tickets must be validated in the yellow machine on the platform before boarding — an unvalidated ticket counts as invalid, plain-clothes inspectors are common, and the fine is €60. There are no turnstiles anywhere, which tempts people to ride without paying, but checks are frequent. Buses 100 and 300 run from Alexanderplatz past Unter den Linden and the Brandenburg Gate to the Tiergarten for the price of an ordinary ticket, making it the cheapest sightseeing ride in the city.

BikesBerlin is flat, with a dense network of cycle lanes and bike-share schemes. A signed route along the Spree and the former Wall runs right across the city. Cycle lanes are often marked on the pavement in a different paving colour, and pedestrians shouldn't step into them. · from €1 to unlock
