Silent Valley National Park is a protected area in the Western Ghats of southern India that conserves an area of largely intact tropical evergreen forest. It is noted for its biodiversity and for the role it played in modern Indian conservation history.

Visitors to the park encounter primary evergreen rainforest, steep valleys, riverine systems and restricted-access trails; the area is valued for wildlife observation and scientific study more than for mass tourism. The main public access point is at Sairandhri, from which trails and guided visits start.

The park gained national and international attention during the 1970s and early 1980s when a proposed hydroelectric dam was opposed by conservationists; it was designated as a national park in 1984 to protect the valley and its ecosystems.

Geographically the park lies in the Nilgiri‑Western Ghats region of southern India, within Kerala’s upland terrain, protecting a steep, forested valley cut by the Kunthipuzha River.

• Protected status: The park was formally designated in 1984 following a high-profile conservation campaign to prevent a major hydroelectric project in the valley.
• Conservation value: The park protects largely intact tropical evergreen forest of the Western Ghats and is important for several endemic and range-restricted species.

What to See#

• Sairandhri entrance and visitor area: Sairandhri is the main entry and visitor area used for park access, trails and basic visitor services.
• Kunthipuzha River: The Kunthipuzha River drains the valley through the protected area and is a significant freshwater feature within the park.

The nearest towns with road access are Mannarkkad and Palakkad. From Mannarkkad, local transport and authorized guides provide access to the park; arrange permits through the Kerala Forest Department.

• Book permits and local guides through the Kerala Forest Department or official park offices-Silent Valley has strict conservation rules.
• Combine a trip with the neighboring waterfalls and the Mannarkkad basin; local guesthouses in Mannarkkad offer the best access.
• Expect steep forest trails and very limited services inside the park; guided treks are recommended.
