Ooty

One of those 'must see' places in Ooty town, the place is thoroughly enjoyable and also informative for the kids, besides the place being very easily accessible. You can actually start the day by a quick stop at the Wax World and then move on to the farther places like Pykara Lake or Mukurthi National Park and so on.
The Wax World contains beautiful statues of Indian freedom fighters like Mahatma
Gandhi, Bal Gangadhar Tilak, Gopal Krishna Gokhale among many others. The museum also has wonderful replicas of social figures like Mother Teresa and our former President, Dr.A.P.J.Abdul Kalam.
Ooty hotels and Ooty restaurants are easily available near the museum for a quick bite before you carry on with your journey. The Wax World also has many replicas depicting the typical Indian way of life, especially in the villages. The whole setting of a village and people doing pottery and farming and so on all made entirely of wax is a wonderful site.
Being a museum, there is no concept of the best time to visit, other than when it is open!
