Diana was a great tour guide and made the tour fun and informative. It was fun to navigate the tunnels and we learned a lot about the downtown architecture and history of Houston. A great “all around” tour for visitors and Houstonians!

Diana was an amazing ambassador for Houston - very knowledgeable and knew how to “spin a yarn” for all types of folks. I am multi-generation Texan and worked in Houston for awhile, but still learned during the Tour!

Diana was a lot of fun to be with. She was knowledgeable and interesting as she told the stories of downtown Houston and the history of some of the buildings. The whole tunnel experience was well worth the cost! Our whole family had a great time.

Very interesting and informative. Our tour guide Diane made the tour enjoyable with her history knowledge of the Houston tunnel system. I learned things about Houston for the first time. Highly recommended.

DIANA was fabulous.... knowledgeable, witty, astute, very entertaining but boy did we learn a lot! GREAT tour - BEST KEPT SECRET! Be SURE to book the valet parking at Residence Inn next to Starbucks meeting place, saved us more than 50% on the posted parking rate!!!

We LOVED this! The tour guide (Diana) was absolutely amazing! She had so much knowledge abt the tunnels and the buildings we visited. And the trivia she added was so fun to know. She was very patient with the little boy on the tour that was very “needy”. I couldn’t have been so patient. This was well worth the tour price!

Diane was very knowledgeable about why the tunnels were built and how they are being used. Because of these tunnels I can see why there isn’t much street traffic.
