Stay on the 6 train at Brooklyn Bridge−City Hall, and when it circles back to head uptown, you’ll pass through a 1920s-era subway station that is no longer in use. Ride the Staten Island Ferry: not for the commute, but for a fabulous—and free—way to take in the downtown Manhattan skyline. Don’t be afraid to solicit help. City residents have gained a reputation for being rude because they are caught up in the hustle and bustle—but if you’re lost, they will happily oblige with directions. Just ask! Avoid the subway at rush hours in the morning and evening: It might be cheaper than a cab, but the crowded trains and terminals could prevent you from getting off at the right stop. Just walk, because the city is at its most beautiful in twilight anyway.
