On Day 4 the most important thing to do is start early so that you'll visit all the places and still make it - to reach Bangalore by night. I suggest you to take route of Bangalore while going back from ooty because ooty doesn't end at ooty town.
Pack your bags, checkout from the hotel and start your end journey towards mysore in a taxi. Do remember to talk to the taxiwala that you wish to see every place in between.
This place comes first while you start travelling towards mysore. The pine forest is a small place by the side of the road with a lot of Pine trees(As the name suggests) by the bank of a beautiful lake . The lake, the pine trees and the cool sand that touches your feet will make you be there of hours. Its ideal for photoshoots. The view is excellent here and can make you sit there for hours.
The shooting Spot:
This is basically a valley where you see greenary every where. You climb a few meters up hill and witness the beauty of mountains. Ideally as the mane suggests this is shooting spot where a lot of movie shoots happen. It also has the replica of the huts that local toda tribes used to live in and is as beautiful as you can imagine.
Pykara Lake :
I don't think there is a lake as beautiful as the pykara lake in the entire nilgiris. The spectacular visual of this lake has made me to just sit there and enjoy the beauty for hours. The lake also has boating facility. I suggest you to take an eight seater boat, irrespective of the number of people you are. If you are more than 8 take two ten seater boats but always opt for the slow boats with the root top. These boats will give you ample time to enjoy the scenic view and will let you blend in the beauty of the place slowly and i somehow got the feeling that we humans are destroying the beauty of the lake(my opinion).
This is perhaps the last destination of nilgiri hills while climbing down. This is the place where the moutain meets the clouds. You can see clouds touching the mountains from here and you can also see the entire plateau standing on the edge. Do visit this place.
Last but not the least
The Madhumalai or Bandipura wildlife sanctuaries:
Both are almost same but the only difference is that madhumalai comes under tamilnadu and Bandipura comes under karnataka states. You have to plan in such a way that you visit these places by 2:00 or 2:30pm otherwise the jeep safari into the jungle would be closed. Just don't miss the jungle safari. Though the visibilty of Tigers are veryless you will find ample other animals like elephants, peacocks, deers and a lot others. If you travel through the forest area in the evening you can see the animals crossing roads also. Its very pleasing to watch.
If you finish everything by four in the eveing you can reach bangalore by night and plan the journey from there on. I suggest you to stop at mysore for a day and visit mysore palace and the iconic church at mysore. This is my idea for an ideal tour to ooty.
Other important Things :
In Ooty lot of keralan food is available. The traditional food also is a mix of tamil and keralan traditional foods.
Hotel Coonoor Ramachandra is one of the best places to eat.
Hyderabad Biryani House also has some good biryani.
While travelling towards mysore in a place called gundlupet there is a restaurant called run restaurant (i don't remember the name exactly) where you get excellent food.
Don't buy chocolates at factory outlets instead buy them at local vendors.
If you are roaming in ooty town try hiring an auto.
Although all the rates are displayed by the taxi unions tryin bargain for some concession.
Try to be a little far from the town so that you can enjoy the calmness of nature.
Camp fires are available in various hotels and home stays. Which may cost a bomb but don't miss on the opportunity to sip a glass a whisky with your loved ones under the sky with camp fire, you will not regret it.
Always start the trip early, nights become calm very early at ooty.
