If you wonder why there are so few pedestrians on the city streets --it's cause of the tunnels. Great when it's raining or too hot. Shops of every type, services like hair salons, and lots of places to eat. Oh yes, it also provides a safe comfy way to get around downtown.

cool idea but not much going on. Confusing directions and not much to see. OK for a hot day activity but not that great.

Of the Houston residents i know, none had ever visited the tunnels. Clearly they are used by the working stiffs who commute into the business and banking high rises downtown and by tourists, but if these... More

Visit with family. Ate at a great Mediterrean restaurant. A lot of walking. But definitely a way t beat the Houston Heat!
