5.00Vanessa was fabulous. She was easy to hear, engaging and knowledgeable. It was an easy pace, toilet stop along the way, mostly in the cool, and so many interesting facts about the history of Houston and their buildings.
Awesome Tour!

4.00This was a great tour and our tour guide Diana was extremely knowledgeable and informative. The only reason I didn’t give it 5 stars is because out of close to 100 excursions I have experienced this was the first tour that ended in a different place that it began, so that was a bit confusing because I am not familiar with Houston so I was a bit turned around. I had to get the tour guide to assist me with how to get back to my hotel (with a little help from iMaps too). Also, usually on tours you normally get 15-30 minutes to shop and/or take pictures or in this case, purchase food at the shops in the tunnels especially since the tour guide suggested how great the food was down there. I was by myself so there was no way I would’ve found how to get back in the tunnels on my own to get to those restaurants, so I was not able to experience any of those recommended restaurants.
Great Astroville Experience
