There are bus services in Iran that connect every town and village of Iran to the rest of the country, particularly to Tehran, where there are three main bus terminals. Gharb (West) Terminal, is close to Mehrabad International Airport and Azadi Square. From there those who intend to travel to the north and west of Iran begin their journeys. Those who wish to go southwards or to travel to the central parts of Iran, must take buses at the Jonoob (South) Terminal, and anyone wishing to visit the eastern parts of the country must begin their journeys the Shargh (East) Terminal.
