Fantastic tour of Nasa and Tunnels back in Houston - Great communication from tour operator regarding the tour pick up point in Houston. Enjoyed the Nasa experience along with the 45 minute Tunnel Tour back in Houston - very informative guide.

A great day underground and in space - The tunnel tour had many fascinating insights into Houston’s history and architecture, all delivered with a fun and quirky twist. Our visit to the Space Center was just as impressive. Everything from the transfer to the entry was seamless and well-coordinated. We received some smart, time-saving tips that helped us make the most of our visit, and our return to Houston was right on schedule. All in all, this was one of the best day tours we’ve ever experienced—both informative and enjoyable.

Amazing tour! - The tunnels were the highlight of our day-tour. Visiting Nasa we knew it was going to be amazing. But wasn't expecting to learn and see so much about the Houston's historic tunnels. Such a good additional to the Nasa tour. Our guide Diana was so passionate about the tunnels and having her guiding us through was a blessing. After that we got to be dropped off at Nasa Center and an amazing experience. Make sure to book the Mission Control tour (add-on), it's worth it. The shuttle was clean and nice. We had a movie playing during the drive to and from Nasa.

Tunnels/ NASA tour. - The underground tunnel tour was too long. Could have added more views around the city on way to and from NASA.

Nasa is a must see - The tunnels were closed so I didn’t get a guided tour there. They were open so I was able to see some of the tunnels later on. The nasa tour was great!

Houston's Tunnels - The Tunnel experience was so unexpected. A truly unique way of life for the people working in the Houston Financial District.
