From Lower Manhattan, take the green line trains -- 4, 5 and 6 -- to get to Rockefeller Center. Get on at the Bowling Green station if you're coming from Battery Park and the Statue of Liberty dock; at the Wall Street station from the Financial District; or at the Brooklyn Bridge station. Get off at Grand Central. Head west on 45th Street, then north on Fifth Avenue. From the Museum of Natural History and other points along Central Park West, take the B or D train heading south to the Rockefeller Center station. Times Square is within walking distance of Rockefeller Center; its subway station is serviced by a number of trains on different lines.
