Because of vast distances, variable road conditions and hair-raising driving, it is advisable to travel long distances by air or train rather than road. Bus journeys can be uncomfortable and tough on the constitution, although a journey of several hours is certainly bearable in a decent air-conditioned coach. It is unwise to attempt to self-drive if you haven't done it before in a big Indian city; hiring a car with a driver from a reputable company is a much better idea. Distances are vast between other major cities (Kolkata, Mumbai etc) so it is more advisable to catch a  train or fly and hire a car and driver locally. During the rainy season, road travel out of town can be hazardous.

The government bus company operates from the huge Chennai Mofussil Bus Terminus (CMBT), Koyambedu (tel: (044) 2479 4705). Closer destinations include Puducherry (Pondicherry) (4 hours) and Mamallapuram (2 hours). There are also private bus companies operating opposite Egmore train station.
