A wonderful way to gain a deeper appreciation for Houston and discover its history, architecture, beauty and even modern business ways. It opens your eyes and curiosity to want to explore and experience the underground tunnels again and again.

Tour guide was amazing and very informative of the history of the buildings and tunnels. The architecture and designs in the buildings were enriched with culture.

So informative from start to finish! Diane was very knowledgeable and gave us history lessons at each turn. Walking tour but goes by fast as you soak up all the history of a few business men/women and the tunnel systems and how they came to be. Definitely worth the money!

Very informative and fun. Great guide Dianna. Have lived here for 50 years and never knew all of what we learned today. All Houstonians should experience this as well as tourists.
