New York City consists of five boroughs: The Bronx, Brooklyn, Manhattan, Queens, and Staten Island. When many people think of what’s in New York City, they are actually only thinking of Manhattan, which occupies Manhattan Island – the theater district of Broadway, the New York Stock Exchange, the Empire State Building, Times Square, and so on. Most of the big tourist areas in Manhattan are located on certain select streets in certain areas, and it’s quite possible to walk everywhere.
The New York City subway system serves all five boroughs and runs 24 hours a day. The system is crowded but most lines are relatively safe – except very late at night, when it is best to take a taxi to your destination, if you must travel that late.
