The guide
Why Silent Valley National Park?
Silent Valley is one of the last undisturbed tracts of tropical evergreen forest in India, tucked into the Nilgiri plateau southwest of Palakkad. It is famous for the lion-tailed macaque and for a rich endemic flora, and it was at the centre of a landmark conservation campaign in the 1970s and 1980s that stopped a hydroelectric project.
Access is tightly controlled. Visitors need a forest permit, usually arranged through the Mukkali forest office, and exploration is on foot with guides. There is basic accommodation at Mukkali and a forest rest house. This is not a casual day trip: the humidity, leeches and limited facilities demand preparation. For travellers who are patient and physically able, it offers a rare sense of primary forest.
Why go
One of India's most important rainforest reserves, with a genuine sense of remoteness and strong conservation history.
What makes it different
The valley's intact evergreen forest and lion-tailed macaque population make it a site of national ecological significance.
