Your adventure begins in Grand Central Terminal’s modern-day heart: the lively main concourse. Marvel at the famous clock perched atop the information booth—and learn the eye-watering amount it’s rumored to be worth—as your guide regales you with the story of Cornelius Vanderbilt, the mastermind behind Grand Central Depot (as it was originally called). From there, head into Vanderbilt Hall, itself a living testament to Grand Central’s rags-to-riches transformation in the 1980s.

Next, pop outside for a moment to gaze upon the largest Tiffany clock in the world from the busy Pershing Square plaza.

Heading back inside, it's time to travel back in time to the Roaring 20s and see a speakeasy style bar that, a century ago, served as the private office of one of New York’s most prominent railroad tycoons.

After a foray into the Whispering Gallery, where you’ll learn just how whispered secrets travel across the busy interchange to be perfectly heard on the other side, you’ll get a peek at one of the largest lost-and-found departments anywhere in the world. Then, peruse the handcrafted designs and jewelry on sale from local artisans in the Graybar Passage before stepping into a fascinating former movie theater, where travel-weary youngsters could enjoy some entertainment back in Grand Central’s heyday.

Last but not least, you’ll weave through the colorful Grand Central Market before making your way back to the main concourse, having gotten a true insider’s look at the most famous train terminal in the world.
