For much of the year, the Billie Jean King National Tennis Center in Queens, New York, is mostly quiet. But for two weeks late in the summer, the place becomes the center of the tennis world as thousands of fans flock to Flushing Meadows for the U.S. Open.

Qualifying matches are already underway, and the main draw of the U.S. Open begins on Aug. 26. The Australian Open, French Open, Wimbledon Championships and the Olympics are in the books, so this is the last chance for the world’s top tennis players to win a major title this year.

A few are favored to win this year, but the U.S. Open has been known for upsets, thrilling matches that can run late into the night.

Here’s what to know about this year’s tournament.

All aboard the No. 7 train.

From Manhattan, one of the simplest — and fastest — ways to travel to the U.S. Open is by taking an eastbound No. 7 subway train to the Mets-Willets Point station. Once you’re there, just follow the crowds to the tennis grounds.

Those in Long Island or Manhattan can also take Long Island Rail Road to Mets-Willet Point. The Port Washington Branch departs Manhattan from Penn Station, with a stop at Grand Central Terminal.
