Silent Valley is considered one of the most ecologically diverse areas on the planet.

In the 1950s, the Kerala State Electricity Board wanted to build a dam across the Kunti river, which flowed in the deep forest. Nationwide protests in India by environmentalists and mass publicity by the media led the then prime minister, Indira Gandhi to order the state government to abolish the hydroelectric project. The area was declared a national park.
