Make the most of your time in Houston with this Guided Downtown Tunnel Tour + NASA Space Center Entry + Transfers combo. Begin with a guided walking tour through Houston’s famous underground tunnel system, the largest in the U.S., and see iconic architecture including Texas’s tallest skyscraper and its oldest downtown bank. Then, enjoy round-trip transfers to the NASA Johnson Space Center, where you’ll explore Independence Plaza, Rocket Park, and interactive exhibits on Mars, the ISS, and the Artemis program. A tram tour takes you behind the scenes of NASA’s working facilities. Spend five hours exploring at your own pace before returning to downtown. This all-in-one experience offers great value, convenience, and insight into two of Houston’s must-see attractions.
Voucher information: You can show your voucher on your smartphone (But if you’d rather print a copy – that’s fine too!)
Please note that on Holiday weeks, guests will be taken to the NASA Space Center first and do the tunnel tour following their return from NASA
