Silent Valley National Park, Palakkad

Silent Valley National Park, located in the Nilgiri Hills of the Western Ghats in Palakkad, Kerala, is one of the most pristine and ecologically significant tropical rainforests in India. Known for its untouched wilderness and rich biodiversity, it is a haven for researchers, nature lovers, and wildlife enthusiasts.

Covering an area of about 237 sq km, Silent Valley was declared a National Park in 1984 and forms a core part of the Nilgiri Biosphere Reserve. The park preserves one of the last remaining stretches of undisturbed tropical evergreen rainforest in the country. Its name derives from the absence of cicadas often loud in other rainforests.

The park is home to endangered species like the lion-tailed macaque, Nilgiri langur, Malabar giant squirrel, and over 100 species of butterflies, 200+ birds, and a wide variety of orchids and medicinal plants. Silent Valley is also an important watershed area and plays a critical role in environmental conservation.

Entry into the park is strictly regulated to maintain ecological balance. Visitors can enjoy eco guided treks, nature interpretation, and breathtaking views from the Sairandhri watchtower inside the core zone.
