Ooty. a well known hill station located in tamilnadu. I have visited there 5 yrs back during winter and the temperature was badly chilling around 5 to 10 degrees. As you can visit ooty in any season, but summer season is best to visit there.
Tea gardens are the main attraction in ooty as ther look marvellous. You will love to have Tea there bcoz u will find a large variety of flavours in it.
The hill station is covered with large no. of eucalyptus and pine trees. There are some points in ooty to visit such as pykara lake, shooting point, rose garden, etc. Many films have been shooted at shooting point such as Raaz, Roza, etc.
Alas I will definitely recommend you to visit this place.
