5.00It’s a whole other world in the tunnels. I’ve live in Houston for 40 years and never knew the extent of this system. Our tour guide, Diana, was awesome. She was well-spoken, energetic, friendly, full of details and facts, fun to listen to, and spoke loud enough for everyone to hear.
Houston underground with Blanca.

5.00Even native Houstonians are not aware of the existence of these amazing tunnels. Blanca’s enthusiasm is contagious. She’s the right person for the tour.
Discovering the tunnels of Houston on a walking tour is insightful and fun.

5.00I didn’t know anything about these tunnels and wasn’t sure what to expect when I booked. What a delight it was exploring the tunnels with our very knowledgeable and engaging guide Diana 🙌 my own curious nature was fuelled by Diana’s answers and her own enthusiasm for the history of this city. It was more than just a tunnel tour, learning how people live and work and this city and a step back in time to the development and growth of Houston through the decades was fascinating.
A must do

5.00Wonderful and very informative tour. Inside most of the time in air conditioning. Learned about many of the fabulous buildings in downtown Houston. You'll know more than many of the people who live in Houston.
Loved it!
