If Brooklyn were its own city, it’d be the fourth largest in the US – bigger than Houston, Philadelphia and Phoenix. It is home to more than 2.5 million people and is a rambling 71 sq miles (easily three times larger than Manhattan). It is split in two, with one set of subway lines servicing the north end of the borough, and another set traveling to points south. So if you think you can see it all in a day, as the locals say: ‘Fuhgeddaboudit!’
For day-trip purposes, it is best to pick a neighborhood and stick to it. South Brooklyn, especially brownstone-studded Brooklyn Heights, offers lots of history and great Manhattan views. Fans of vintage amusement parks should head to Coney Island. For the night owls, the trendy enclave of Williamsburg lies just a single subway stop from Manhattan and is loaded with bars and restaurants.
If you are interested in other parts of town, ask around first. The borough may be all the rage, but it’s not without its sketchy parts.
