Downtown Houston Tunnel System - Houston (TX)

5 /5 Ian Murillo: It is a very good place to walk through the city without crossing streets or having sunburns. It is closed after evening and not open on weekends for safety, but open to the public during the day, it has A/C, big halls and easy to understand routes, it also has access to several buildings, and even has some underground food areas, restrooms and office spaces. Real cool and useful infrastructure.

4 /5 j b: The tunnels entrances arent signposted, so it took us a little while to find one. The entrance we found was a large lobby with just escalators. Once down in the tunnels there are maps. Down in the tunnels there are restaurants and shops, theyre clean and air-conditioned. The tunnels seem to be used by the office workers. Be prepared to get a little lost, there are signposts but theyre not always clear, some take you through Hotel function room corridors. Ive added a map but the tunnels do extend beyond this.

4 /5 X V: I finally saw this today after living here for over a decade. Very cool and fun. Air conditioned, safe, and clean! I went through 3 or 4 different paths. I was able to get over 15,000 steps in! Nice variety of food. Plenty of places to sit. Understory has foozeball. Some sitting areas have TVs. 4 stars because, I felt like I was on a scavenger hunt to find a person to ask for an access card for a bathroom. I will be back to go to the other paths I did not go on today! Cool art too.

5 /5 malathi govindaraju: Walking around the entire downtown Houston area for about the past 5 months, I suspected underground garages connected to buildings due to the building sizes, the lights on there and with so few people walking on the streets. Even though it was near the end of the pandemic something seemed amiss. I never imagined that there were so many interconnected tunnels, skywalks, entrances, streets, garages, buildings, offices, shops and patios. One person stated that it was six miles in total length! I thought only people who work in these buildings could enter. On impulse I stepped into one of the numerous entrances; few are clearly marked. The entire system is kept immaculately clean. On a stormy/windy/hot/sunny episodic day, it can be a life saver. It can also be an incident avoider. During office opening/closing/lunch hours it feels like a human bee hive. My blood pressure shot up. At times other than office business hours, it is deserted. Then it felt scary. Most of the shops open late and close very early. They appeared to serve one and all. Eateries may only be open two or three hours for breakfast or lunch. Upon an item purchase some eateries provide a code or key for restroom use. Some ring up a purchase then inform you they only accept cards. With so many cameras, computers, security personnel, workers and people, I suspect they evaluate one and all. (see photos) There are three marked entrances to the tunnels in the one square block of McKinney-Main-Travis-Lamar. Stairs and elevators to the tunnels reach maps and retail store lists. It might not be a good idea to explore without reason. (more assorted photos)

5 /5 Thomas Piland: The downtown tunnel system is a quick and convenient way to navigate the city from parking structure to office or concert venue. There are security cameras and the tunnels are clean. I do recommend having a companion if traveling at night as they can get pretty sparse.
