Silent Valley National Park
Overview
Silent Valley: Kerala's Last Untouched Rainforest
Silent Valley National Park sits deep in the Nilgiri hills of Palakkad district, protecting one of the few remaining stretches of virgin tropical evergreen forest in India. The park exists today because a wave of public protest stopped a hydroelectric dam project on the Kunthipuzha River in the early 1980s. Entry is permit-only, and every visitor must be accompanied by a guide from the local Forest Department.
A typical visit takes about half a day, and the road from the gateway village of Mukkali runs through coffee plantations before reaching the forest edge. Sightings of the lion-tailed macaque and the Nilgiri langur are among the biggest draws, along with the sound of the Kunthipuzha River running through the valley.
Open Hours
Open Days: All days of the week

Visitors report to the Forest Department office at Mukkali to collect their permit and guide before heading into the park. The park also stays closed to tourists for a stretch between March and May each year, so it's worth checking availability before planning a trip in those months.

About Silent Valley National Park
Silent Valley National Park lies in the northeast corner of Palakkad district, on the southwestern edge of the Nilgiri hills, about 40 kilometers northwest of Mannarkkad. The forest was marked as a Reserved Forest as early as 1888, but it was the movement to save it from a proposed hydroelectric dam in the late 1970s and early 1980s that brought it national attention. The government dropped the dam project, and the area was declared a national park in 1984, formally inaugurated the following year.
The park takes its name from the near-absence of cicadas in its forests, a quiet that struck early British visitors compared to the noisy jungles nearby. It forms the core of the Nilgiri Biosphere Reserve and is part of the Western Ghats UNESCO World Heritage cluster, recognized for sheltering one of the last undisturbed stretches of South Western Ghats rainforest in the country.
The Kunthipuzha River runs through the length of the valley before joining the Bharathapuzha, Kerala's second-longest river. Vehicles can travel only as far as Mukkali; from there, the road into the buffer zone leads to the watchtower and forest station at Sairandhri, beyond which the core zone is closed to general tourists and reserved for research and specially permitted treks.
Silent Valley holds an unusually rich botanical record, with more than 1,000 species of flowering plants and over 100 kinds of orchids recorded within its boundaries, some found nowhere else.
