If you’ve ever wanted to see a side of New York City most visitors don’t get to experience, this tour might be just what you’re looking for. It promises a mix of secret tunnels, stunning architecture, and iconic landmarks, all packed into a two-hour journey for around $50 per person. While I haven’t tried it myself, I’ve gone through the details and reviews to give you a balanced look at what you can expect.
What immediately appeals to me about this experience is the idea of walking through a hidden underground tunnel that doubles as an art gallery—something that feels like exploring a city’s secret passageways rather than just ticking off a tourist checklist. Plus, the stops at Grand Central Terminal and the NY Public Library are real highlights, offering a chance to slow down and appreciate some of NYC’s most celebrated spaces.
A small, potential drawback is the short duration—just about two hours—meaning it’s more of a quick taste than an in-depth exploration. Also, since the group is limited to 12 people, it could feel a bit crowded during peak times, but the intimate setting is a plus for those who prefer smaller tours.
This tour could be ideal if you’re into discovering hidden corners, enjoy a mix of art and architecture, and want a manageable, well-paced way to see some of Manhattan’s most famous spots with a twist. It’s perfect for curious travelers who want a bit of adventure without spending a whole day on it.

Stop 1: The Secret Tunnel & Art Gallery at LIRR Concourse
Our adventure begins with a walk into a hidden underground tunnel that’s relatively new but feels like stepping into a secret world. This space is styled like a gallery and features art from globally recognized artists and photographers, making it a surprising addition to a city known more for its skyscrapers and museums.
Travelers can expect to step off the street into an elevator that takes them down into what almost feels like a private art exhibit, with the added thrill of discovering something not on most travelers’ radar. The 40-minute visit here, with admission included, is a chance to see some impressive works while feeling like you’re in on a secret.
Stop 2: Grand Central Terminal
From the underground, we emerge into the heart of NYC at Grand Central Terminal—a place that truly needs no introduction. Standing underneath the 125-foot high ceilings adorned with constellations, you’ll probably find yourself gazing upwards, marveling at the architecture that’s both grand and intricate.
Highlights include the famous gold clock, the whispering gallery, where sound travels in a way that allows you to have a secret conversation from opposite corners, and the Oyster Bar—a historic spot worth a quick peek. The 30-minute walk also hints at some behind-the-scenes secrets, like the secret speakeasy, which adds an extra layer of curiosity.
Travelers love the timeless beauty of Grand Central, and many reviews mention the peaceful moment of slowing down amid the bustling city. It’s a perfect spot for photos and soaking in some classic NYC atmosphere.
Stop 3: The New York Public Library
Our final stop is the Stephen A. Schwarzman Building, better known as the NY Public Library. This site is a cherry on top, boasting a grand main room, a famous mural in the McGraw Rotunda, and three floors of inspiring architecture and exhibits.
The 25-minute visit allows you to admire the ornate interiors, gaze at the stunning murals, and get a sense of the library’s role as a palace of knowledge. While free to enter, this stop offers a chance to enjoy the museum exhibit and soak in the timeless elegance of this NYC institution.
The Flow and Experience: What It’s Like

The tour begins at 420 Madison Ave, a convenient location near public transportation, at 1:00 pm. The group size is capped at 12, promising a more personal experience and fewer crowds.
The pace is relaxed, giving enough time to appreciate each space without feeling hurried. The hidden tunnel and art gallery set the tone with a sense of discovery, while the stops at Grand Central and the library serve as a chance to breathe in the city’s history and architecture.
Expect a mix of guided commentary and free exploration. The admission tickets are included for the tunnel and Grand Central, but the library is free. The entire experience runs around 2 hours, making it a great addition to a day of sightseeing without overloading your schedule.
What Do Travelers Say?

Since reviews are still building, some comments from those who have experienced the tour hint at what to expect. One traveler appreciated the unique aspect of the secret tunnel, describing it as “a hidden gem that felt like unlocking a secret part of the city.” Others enjoyed the intimate group size, noting, “It’s nice to have a small group, so we could ask questions easily.”
Some comments also point out that the tour is quite fast-paced—if you’re a lover of slow sightseeing, you might want to add extra time at each site. But overall, the value for the price seems solid, especially with the included admission fees and the chance to see some lesser-known spaces.
The Bottom Line: Who Is This Tour Best For?

This experience is perfect for curious travelers who enjoy uncovering hidden corners of a city and aren’t just after the typical sightseeing. It’s suited for those who appreciate a mix of art, architecture, and history in a very manageable, small-group setting.
