You can easily walk or bike around the city, but you can also take the bus, tram, trolleybus or metro around Bucharest. With these forms of public transport you can get around the city safely and efficiently. Bus, tram and trolleybus tickets can be purchased at any RATB kiosk. Punch your ticket in the machine board to avoid a fine. Transport runs from 4:30 am to 11 pm. Night busses are available after that. Bucharest’s metro has four lines. Trains run every 5-15 minutes, every 15-20 off-peak, from 5:30 am to 11 pm. Sit at the front of trains to avoid missing station signs which are not clearly signposted. The metro is good for travelling longer distances. Tickets can be used on all means of transportation except the express buses.
