New York City’s annual West Indian American Day Carnival, held on Labor Day, will head to Crown Heights in Brooklyn once again for a day of festivities that celebrates the history, culture, music, food, and people from myriad Caribbean countries. Each year, the parade attracts more than a million people, making it one of the, if not the, largest Caribbean celebrations in the country.

Expect the route to be packed with revelers (say goodbye to your personal space), including many people in gloriously colorful costumes. As the various floats go by, enjoy sounds of reggae, soca, calypso, and dancehall and the unique dance styles that go along with them. Vendors will also be selling clothing, food, and other goods that are representative of the various countries involved.

How to get to the West Indian Day Parade

The MTA’s subways and buses will be operating on a Sunday schedule, and many train stations in Brooklyn may be affected by the parade; the 2, 3, and 4 trains are going to be your best bet, since they stop at various points close to Eastern Parkway.

There are, however, some service changes in effect on Monday. According to the MTA, the 4 train will be making all local stops in Brooklyn. The Eastern Parkway-Brooklyn Museum stop will be closed, and trains will bypass it, from 6 a.m. to 8 p.m. on the day of the parade. And “certain staircases will be designated entrance/exit only” at the Crown Heights-Utica Avenue stop.

There are also various buses that stop along the route, including the B12, B14, B17, B41, B43, B44, B44 SBS, B45, B46, B46 SBS, B48, B49, B67 and B69; check the MTA’s website for more information on those routes. Be warned, though: those are likely to be slow, given all the people who will be out and about for the event.
