Coimbatore is a booming tier 2 city, reportedly the fastest growing among such cities. It already has two five star hotels, and a few more are expected to open shop in the next two years. It is the second largest city of Tamil Nadu.
It is a superb educational center, with at least ten very good engineering colleges, one of the best Agricultural Universities in India, and a topography similar to Bangalore. Since it is very much a part of the lovely Western Ghats, the city is well known for its lovely climate for ten months in a year --except April and May -- when it hots up a bit.
The next time you come to the city, please do visit the superb Lord Muruga temple at a place called Marudhamalai, which is also the place where the Bharathiyar University is situated. Though you have autos, you can jolly well take a bus to this place, as there are plenty of buses. And to go right up to the top of the small hill, you have buses that charge you just Rs.10/- per head and take you there.
Apart from the neatly maintained temple, the surroundings will offer you the most panoramic view of the booming city, which is now expanding to over forty kilometers on all the four sides.
