Downtown tunnel system

Frommer's Review

There are 6 miles of tunnels below Houston's downtown; most of the system is private property. Along those corridors are restaurants, shops, and businesses of all varieties. You can get a map of the tunnels from the city's visitor center or you can take a guided tour if you schedule it in advance.
