I visited Munnar in 2015, it was an awesome place. Fully green covered with tea plantations.
Below are the bullet points of my experience
Its heavenly covered in green.
There was a lake just opposite side of my hotel which made it look like a scenery and very beautiful.
I found a spa shop in local market and it was a refreshing experience in very less price.
There is high, pleaute and plain also.
Food is good, fish is tasty.
Local transport is cheap and since its a small price drivers knows all the tourist spots and very smoothly shown all the famous tourist spots in 6-7 hours.
I felt very near to nature, clean green free of pollution, joyful and awesome experience.
Will visit again with family again.
