NYC SECRET: Tennis Court in Grand Central Station🎾 Did you know that you can play tennis on a hidden court within Grand Central Terminal? Vanderbilt Tennis is one of NYC’s best kept secrets. It’s open to the public, and offers kids classes! It doesn’t get more New York than this. Here you will find a one-of-a-kind single court, featuring Grand Central’s iconic arch window overlooking Park Avenue. The stunning court is regulation sized and made of US Open grade “Deco-Turf”. There are also 2 practice courts on the upper level, which have an automated ball machine that can be programmed to your level. The practice court also has a retrieval system (no need to pick the balls up!). The court and practice courts can be rented in a variety of ways - including for private court time, lessons or group lesson sessions. Children’s group lessons start at age 3.
