The major taxi companies in Chattanooga include: United Taxi Operators, Millennium Taxi Service, Checker Cab, Mercury Cab, and Redbird Cab.  There are a few cab stands in downtown Chattanooga, but at most locations you will need to call for pickup.  The best method might be to enter the cab company’s telephone number into your cell phone before you leave for your trip, and then, when you know that you will be needing a cab, call for pickup.

As for rental cars, within seven miles of the center of town you will find Enterprise, Thrifty, Hertz, National, Avis, Dollar—all the big rental car names.  Most people, if flying into a nearby airport, will simply rent the car from the airport.  This is an especially good idea for Chattanooga, as the tourist sites are spread out, the public transportation is that of a minor city, and cab rides are relatively expensive.
