Fodor's Expert Review USTA Billie Jean King National Tennis Center

Each year, from late August through early September, 700,000 fans come here for the U.S. Open, which claims the title of highest-attended annual sporting event in the world. The rest of the year, the 34 courts (19 outdoor and 12 indoor, all DecoTurf, plus three stadium courts) are open to the public for $38–$72 hourly. Make reservations up to two days in advance. Parking is free but limited.
