2. Hidden Tennis Courts

The hidden tennis courts on the fourth floor of Grand Central Terminal are a favorite stop on ourSecrets of Grand Central Terminal tour. The courts, run by the Vanderbilt Tennis Club, are open to the public but few people even know they are there. The space where the full-sized hard court and two practice courts of the tennis club are now located, called The Annex, once served as an art gallery and then as a television studio for CBS. In the 1960s, Hungarian immigrant Geza A. Gazdag founded the Vanderbilt Athletic Club in the terminal and constructed a 65-foot-long indoor ski slope made of astroturf and two clay tennis courts in the Annex. In the 1980s, the club was taken over by Donald Trump and catered to the rich and famous as a private court until the early 2000s. At that time, a new fourth floor was built and new courts became more accessible to the general public.

The easiest way to access the facility is to head to the Campbell Apartment, where you will find elevators in the lobby outside the bar that will bring you directly there. Alternatively, you can also take the elevators located halfway down the ramp that leads to the Oyster Bar and Tracks 100-117. There is even a street entrance on Vanderbilt Avenue (between Madison and Park Aves.) between 42nd and 43rd streets.
