Ooty (aka Ootacamund - Kothar Mandhu - House of Kothars), is the Lovely place on Planet Earth. Best compared to Shimla, Kodaikanal and Yercaud.
With Dodabetta, peaking on the top and the Ketty valley (Santhoor) on the downside, this is one wonderful place on the Earth.
It can be reached from Two sides, one from Gudalur and the other Mettupalayam. It is about 2.5 hours uphill drive.
Coonoor comes first, on the way, with a view on the side - vallies and all.
All the Indian movies song scenes are shot here. There is Manjoor which is the best.
The cost of stay would be cheap from Rs 400/- to Rs 4000/-, based on budget per day. The sight seeing cost is cheap, with auto-rickshaws plying around.... Food is also cheap. Hot vegetarian food is served in most of the hotels.
What else can I say, having lived closer to Ooty at Kotagiri, just 18 kma away.
The best family vacation spot - cheap and best.
