Manhattan, although the smallest of the 5 boroughs in size, is the most densely populated in New York City. It is also the premier destination of tourists while in the Big Apple. People come here for the bustling streets and bright lights of Times Square, the historic sites of Lower Manhattan, to walk around in Central Park, to shop in Fifth Avenue, and to take in the sweeping views from the observation decks of the Empire State Building and Top of the Rock.
