Silent Valley National Park, Kerala

“A mystery half revealed and half concealed, that is a story older than mankind”

Silent Valley National Park occupies an area of 237.5 sq km within the abode of Western Ghats. A place bustling with life forms of all kinds lies shielded by the cover of unique rainforests, the last of its kind to be surviving in the state of Kerala. A varied blend of habitats supporting a huge biodiversity can be found here. Even amongst such chaos, this place emanates with serenity. The park also has immense historical significance. For starters, you might be walking on a land aged as much as 50 million years! It is believed to be the setting for the epic Mahabharata. This land has also witnessed the revolutionary movements to protect these magnificent forests. It is due to these movements and people’s determined efforts that the park has been preserved in its pristine condition.
