Kodaikanal is the best hill station to visit in tamil nadu they say ooty is more famous than kodaikanal but I personally say kodaikanal has more place to visit then ooty, talking about the climate it is no less than ooty, the climate is always cool and it will be below 19 to 22 degree during summer. the view of silver falls will be awesome since the falls run under the road way( bridge) the boating is as usual as in ooty and many other place such as thopithoki, guna caves etc are awesome to visit and the most special item over there is home made chocolates which will be so yummy.
