Silent Valley. From the name itself it attracts tourists towards it and when they reach here, they simply fell in love with it. Let us clear that we are mentioning about the Silent Valley, near Munnar, Kerala and not about the Silent Valley National Park located in Nilgiri Hills, Mannarkkad, in the Palakkad District of Kerala. Both of these are two different places but equally eye-catching. The Silent Valley is a stunning green landscape and named as it is found inside the Silent Valley Tea Estate.
