Prague has a cheap and efficient public transport system consisting of an integrated network of buses, trams, metro and a funicular on Petrin Hill. The historic center is compact and pedestrian-only, but trams offer an inexpensive way of seeing the rest of the city and there are plenty of metro stations in the center. Tram lines criss-cross the center and are the best way to get around, after the metro. Buses need rarely be used, as they tend to operate outside the center and are more irregular. After midnight night trams and buses offer a limited service, usually every hour. Tickets are valid
on all modes of public transport, but must be bought in advance and validated before each journey. A number of travel passes are also available; these are the best way to avoid the hassle of different single tickets and need only be stamped once at the start. Prague is inundated with dishonest, unregistered taxi drivers who attempt to rip off tourists. It's best to book taxis over the phone and demand a receipt for the fare before setting out. ProfiTaxi or AAA Taxi are the most reputable companies. A car is unnecessary since much of the city is pedestrianized, parking is a major problem and vehicle crime is rife. Car rental is also expensive.
