Just back from Thekkady. Booked a car for the whole trip and found absolutely nothing worthwhile. Spending time, effort, and money just for the boat ride on Periyar Lake is not worth it. Not sure what the hype is all about. Not a single animal was seen. The 7.30 am boat ride takes lot of effort and hard work as there is rush of people for misty ride. There was absolutely no mist and no animals, 9.30 am ride is almost the same.
Its better to stay in Munnar for extra day and return than wasting time, effort, and money here. Not worth it.
