Absolutely awesome! Took the Secrets of GCT tour with Justin this weekend and have done a private Subway tour with Justin in the past. Both were AMAZING. The tours are well planned out and chock full of interesting information. Justin is enthusiastic, very knowledgable and comes with visual aids/pictures including photos he has taken himself that really amplify the experience. You know you are learning from someone who has a passion for the secrets and history of NYC. Justin is approachable and makes sure everyone has a great experience. He texts prior to the tour to make sure you are appropriately prepared to get the most out of the tour and comes prepared with sanitized earpieces to ensure that everyone can hear him despite the loudest of subway trains or train announcements. Will definitely be taking more Untapped tours in the future and would not hesitate to recommend this group to anyone!!

One of the best NYC tours (especially for NYC natives) This was the best local NYC tour I'd been on in years (and I live in NYC). The tour should really be called "The History and Secrets of the NYC Subway." I thought Justin was great -- he knows so much, but he didn't overwhelm you -- he knew exactly how much information to give and truly the most interesting stuff. At two hours, it was just perfect. All I kept thinking was -- I can't wait to show off my new subway knowledge to my friends and kids. It was 100% cool.

Learned many fascinating things about the NYC subway system that I had absolutely no idea about. Loved all the personal background an inside stories, and how he pointed out things in the stations and explained why they were there and who put them there.
Wonderful tour

We did the tour with Heather, an architect and New Yorker of many years. She was awesome! She was so knowledgeable, friendly and funny, and the group enjoyed being quizzed about the facts and timeline of the New York subway details. She even showed us the hidden gems and lesser-known nooks and crannies of the subway stations we stopped by. A highly recommended experience!

Our tour with Justin was fascinating and gave us a much better understanding and appreciation of the nyc subway system. I’ll,from now on, feel a little smug knowing I have “secret, insider knowledge” about the history surrounding the subway and all its secrets whenever I’m aboard.

This is a great tour! Is you saw New York above ground, you should definitely see New York underground. Our guide was super enthusiastic and knew absolutely everything.

Wow, had such a great time on this tour! Justin was an awesome guide, and I loved the insider's view and random trivia about the city subway and all the abandoned stations!

What an urban adventure! Justin was knowledgable, interesting and engaging, we learned so much - not just of the NY subway system but of NY's history and the city in general. Highly recommend!

Such a cool tour! We got to see abandoned train stations from the subway that I would never have noticed on my own, learn about how the city is all connected, and how the subway system came to be. The tour is a fun underground exploration through Manhattan with awesome visuals. Justin made everything exciting and welcoming. This is a great tour for visitors or locals, or both!

This tour was amazing! Mandy is a fantastic guide who made the history of the subway fun and engaging by showing us old tokens and telling interesting stories about all of the stops we made. I would highly recommend this tour for anyone visiting NYC, or even for New Yorkers, it gave me a new appreciation for the subway.

Taking this tour made me realize all of the history and art I was passing just getting in and out of the subway. Justin pointed out so many cool things and had great stories to tell as we rode between stops. I definitely look at the subway now in a whole new light.

Loved learning about the history of the subway. The guide pointed at many things which I would never have seen on my own

As a New Yorker, I'm usually trying my best to get out of or avoid the subway. I did this tour with friends from out of town, and it was actually really good. I came out with a better appreciation for the intricacy of the subway and fun facts about the art in the stations. Justin also did a good job of keeping the group together while navigating the subway and all the characters you can run into. Definitely worth it.

This was such a cool tour! Whether you’re a longtime New Yorker or first-time tourist, there’s definitely something for everyone. Go on this tour, learn some really interesting facts, see cool underground sights you’d never expect, impress your friends with your street-savvy.

This. Tour. Is. Ridiculously. Cool. Can't recommend this experience more highly. Justin was an amazing guide (This is my 2nd tour with him! Dude rocks.). What I loved about his experiences are that they give you an inside view into some of the oldest NYC institutions -- in this case, the subway. This experience gets you behind the scenes of the NYC subway and it's super interesting. As someone who has commuted on the subway for years, there is so much I didn't know about the history of the thing or how it works. Highly recommend this tour!!

Thank you for an amazing tour, my wife and I had a blast! Although I have taken the NYC subway many times, I never saw any of the cool things Justin pointed out on this tour. And riding through City Hall station felt very special... highly recommend!

Best walking tour I've been on by far! My friends and I went on this tour because we are interested in architecture and urban planning. We learned a ton about the subway system and so many cool facts about old architecture in the Financial District. The tour ended with a trip through to the Oculus, and it was amazing to be able to look at the incredible architecture while hearing about the context of how and why it was built.

I would highly recommend this to both tourists and New Yorkers who want to learn about the history of the Subway and the Financial District. Honestly, I had a big grin on my face throughout the entire tour.
