This was our second tour with Untapped New York, and we absolutely loved it! This was our first tour during the pandemic, and we were able to appropriately social distance. I love the in depth stories and fun facts that the guides tell so eloquently. The GCT tour was 90 minutes—perfect length for learning but not too long that our feet were tired. We learned about the ceiling of the main atrium, the windows, secret walkways hidden in plain sight, and the architecture of the building. Can’t recommend Untapped tours enough—feel like they’re great for locals or tourists who want more in depth knowledge, and the guides are very personable and able and willing to answer all your questions!
