This downtown, multimillion-dollar tunnel system gives new meaning to the term underground. Those who venture beneath the city will be delighted at what they find hidden there. Restaurants, hotels, gift shops, and many more fun spots line the corridors. The temperature below is always pleasant and allows the busy people of downtown to navigate in comfort, regardless of the season. Major buildings that are connected by the tunnel system include One Allen Center, Shell Plaza, Alley Theatre and Wortham Center. If you are not familiar with the layout, you might want to pick up a tunnel map, or call to schedule a Tunnel Tour. Even the natives get lost in the jungle on occasion. Reservations are suggested for all tours. Guided Tours: USD5 per person.
