Full description

Discover why Houston, the most populated city in Texas and the 4th most-populated city in the United States can look like a ghost town during warm summer days. This is because just 20-25 feet below street level, there are more than 7.5 miles of underground tunnels that encompass Texas' tallest skyscrapers and serve as a corporate playground for a multitude of Fortune 500 companies. Start the tour in Downtown Houston and set off on a unique tour to some of the city's most well-renowned skyscrapers. Enjoy great photo opportunities alongside Texas' two tallest buildings, the oldest bank in Houston, and the newest portion of the downtown tunnel system. During the tour, learn all about the history of the city's extensive Tunnel System and its modern corporate appeal including a diverse range of great dining options and business amenities that resemble Houston's diversity.

Our tour guide Vanessa was so personable and so into her job. She has a genuine love for the city of Houston, as well as for the tunnels she guided us through. Her excitement and descriptions of each of the places we visited made this tour a memorable one.

It was a great experience. We weren’t expecting how alive the tunnels are but we loved it. Our guide Vanesa was extremely nice and fun to be around. She knew the history of the places and the people that works there. You could tell she has been doing this for a while. I fully recommend this activity

A friend recommended this tour to me and I have to say that it is the MUST DO thing in Houston. The mall and NASA are nice but the underground tunnel is the hidden gem of Houston. Thank you to Luis for such an amazing tour. I learned so much about Houston’s history. There were 6 people on tour and our guide answered all our questions. Great way to spend a day in downtown Houston!
