The Silent Valley National Park brilliantly tucked in the Palakkad district of Kerala is a treasured resource of biodiversity. Situated in the Kundali Hills, 40 Kms from Mannarkkad, in the Western Ghats in Kerala, the Silent Valley National Park is one of the few remaining pristine forest areas in the Western Ghats. It is reckoned as India's last tract of tropical evergreen rain forests. This green paradise faced severe threats during the 1970's, because of the construction of a dam across the Kunti River, which flows out through it.

It was declared a National Park in 1980 and forms the core area of the Nilgiri Biosphere Reserve.
