Chinnar Wildlife Sanctuary in Idukki is home to the Great Grizzled Squirrel of India. Numbering less than 200, they are among the most endangered species on the planet. Its unique location in the Western Ghats has ensured it gets less than 2 months of rainfall annually. The wildlife along with the deciduous trees makes it an ideal spot for trekking aficionados.
The beautiful Sandalwood forest nearby is highly recommended for a visit. One can view herds of gaur and elephants strolling around casually in this area. Dry deciduous forests, high ranges and some grassland add to the diversity of the sanctuary. While making the journey from Karimuthi to Chinnar, Spotted Deer, Sambar, Hanuman Langur and peacocks can be spotted alongside the road.
