What You Can Expect

Houston from Above and Below: Chase Tower and Underground Tunnel Tour

Underground Shopping District

Greet your knowledgeable guide at a central Houston location and receive a fascinating introduction to Houston’s epic Downtown Houston Tunnel System. Discover the function of this subterranean system and then stroll down Main Street to see the majestic stained-glass windows of the Chase Bank Building. 

Leave the sunlight in favor of the darkened depths of the tunnel system and descend 20 feet (6 meters) below ground to explore the air-conditioned labyrinth. Make your way to the underground entrance of the Chase Tower, Texas’ highest building, and ascend to the 60th-floor sky lobby in a swift elevator. 

Absorb incredible panoramas before capturing photographs beside Joan Miro’s magnificent ‘Personage and Birds’ sculpture in the lobby. Stroll onward to admire the award-winning skyscrapers of Pennzoil Place, and then return to the city depths to visit the underground One Shell Plaza and meet the owners of a subterranean gift shop.

Return to street level via an escalator and enjoy a leisurely wander through Hermann Square Park, passing City Hall and Wells Fargo Plaza, the tallest all-glass building in the western hemisphere. 

Delve into the tunnels one last time and opt to enjoy lunch in the underground network’s varied food court (own expense). Revitalized, return to sea level and bid your knowledgeable guide farewell.

Very interesting guided tour. Guide was a bit late, but that was no problem in the end as we got some basic history and overview of Houston. Fascinating city.

Who would have guessed there are 7 miles of tunnels (but more like an underground connector, people connector and shops/restaurants to support the high rise buildings in downtown Houston. The architecture in each building is quite different and our guide described the differences as we walked underground through part of the tunnels. Since the tour, we talked to many people from the Houston area on a cruise that had heard of the tunnels, but never visited.
One temporary downside to the tour, the Chase Skylobby with aerial views of the city, has been closed for renovation for several months.

The two tour guides were very well educated and complimented each other well. Got a lot of good history of the city, enjoyed tunnels. Was a little disappointed that we could not go up to the sky lobby as if was closed. Only drawback is that the description talks about entry fees being included, and I was a little disappointed to find out that was because they don't actually take you anywhere that requires entry fees.
