I think we are having many Hill stations in Tamil Nadu, there are lot of people who are coming as tourists in visiting these places. The most important Hill stations in Tamil Nadu are Ooty, Kodaikannal, konor etc., People often visit the first two namely Ooty and Kodaikannal and there are various colleges and schools that tend to take their students to these places for tours. I think these are the perfect locations to tour with your family members. I think Ooty is somewhat clean than Kodaikannal, but in case of Cheap mode Kodaikannal is best.
