Getting to & from Tamil Nadu
Chennai Airport will be your probable point of entry if you’re flying into Tamil Nadu from overseas, although Trichy and Coimbatore have (limited) international services as well.
From inside India, there are domestic airports at Chennai, Trichy, Coimbatore and Madurai; these four cities are also the state’s major train junctions.
In addition, the Indian rail network is one of the best transport options in the country and provides the most affordable and convenient way to travel around Tamil Nadu. All Tamil Nadu cities and towns are well connected by rail.
The Tamil Nadu Goverment Bus services also connect the cities and towns within Tamil Nadu. However, it is advisable not to travel long distances by bus and to keep bus journeys to short distances as the roads in India are some of the worst in the world.
