The sanctuary is located in a rain-shadow zone, receiving significantly less rainfall than neighboring areas in the Western Ghats.
It is home to the Mugger crocodile, found specifically in the Pambar River.
The sanctuary contains megalithic burial sites known as dolmens, dating back to the Iron Age.
It supports 225 species of birds, including the rare yellow-throated bulbul.
The park serves as a critical corridor for elephant migration between the Anamalai Hills and the Palni Hills.
Prehistoric rock paintings can be found in the Attala, Manala, and Kambakkoor regions of the sanctuary.
Chinnar Wildlife Sanctuary is a unique rain-shadow region in the Western Ghats, characterized by dry deciduous forests rather than typical tropical wet forests. It is one of 12 wildlife sanctuaries in Kerala and serves as the only habitat for the endangered Grizzled Giant Squirrel in the state. The landscape transitions from thorny scrub forests at lower elevations to high-altitude shola grasslands. Visitors can observe the sanctuary through trekking tours guided by the local tribal community. The Chinnar and Pambar rivers traverse the park, providing vital water sources that support a diverse fauna including elephants, leopards, and crocodiles. The area is also significant for its prehistoric dolmens and rock paintings located within the sanctuary boundaries.
The viewpoint overlooking the Pambar River valley provides wide-angle vistas of the dry forest canopy.
Book trekking and nature walk guides through the Eravikulam-Chinnar eco-development committees.
Bring binoculars and a telephoto lens, as animal sightings often occur at a distance.
Wear neutral-colored, comfortable clothing and sturdy walking shoes suitable for rugged, uneven terrain.
Do not attempt to trek off-trail or enter restricted zones without an authorized forest department guide.
Strictly follow 'no plastic' policies, remain silent during wildlife treks to avoid disturbing animals, and do not litter.
