Kalakkadu Wildlife Sanctuary

Introduction: The Southern Stronghold of the Western Ghats

Situated in the southern fold of the Western Ghats in the Tirunelveli district of Tamil Nadu, at an elevation ranging from 100 meters in the foothills to over 1,770 meters (Agasthyamalai peak region) above sea level, approximately 275 kilometers (a 5.5-hour drive) south of Tiruchirappalli (Trichy) and 45 kilometers from Tirunelveli city, the Kalakkadu Wildlife Sanctuary (also spelled Kalakad Wildlife Sanctuary) is an ancient, biodiversity-rich forest reserve. Formed in 1976 and later integrated with neighboring Mundanthurai to establish India's first tiger reserve in Tamil Nadu—the Kalakkad Mundanthurai Tiger Reserve (KMTR)—this reserve spans over 250 square kilometers of protected wilderness.

As part of the UNESCO World Heritage Agasthyamalai Biosphere Reserve, Kalakkadu is world-renowned for its wet evergreen rainforests, endemic flora, high-altitude rivers, and crucial role in protecting endangered primates like the Lion-tailed Macaque.
