Chinnar Wildlife Sanctuary is situated in the Devikulam Taluk of Idukki district of Kerala. Situated in the rain show region of the Western Ghats, it was declared a wildlife sanctuary in 1984 and is said to be the second habitat for the endangered species of Giant Grizzled Squirrels in India. A thorny scrub forest with an area of 90.422 sq km, Chinnar is an undulated terrain with rocky patches varying from the altitude of 500 m to 2400 m above sea level and thus, there is diversity of climate and vegetation here. The highest peaks in the sanctuary are 2144 m high Kottakombumalai, 1863 m high Vellaikal malai and 1845 m high Viriyoottu malai.
With a short monsoon period of only about 48 rainy days in October – November, the forest consists mostly of thorny scrub forests, dry deciduous forests, high sholas and wet grasslands. The other highlights of this wildlife sanctuary are Elephants, Gaurs, Panthers, Spotted Deers, Sambars, Hanuman Langurs, Peacocks, Star Tortoises and Travancore evening browns. The xerophytic species of scrub thorny forests do little to hide the splendid and graceful deers galloping away in the sanctuary. However, to get the excellent views of the game, watch towers have been recently erected that rise high above the vegetation. The nearest railway station here is at Ernakulam. One can visit the sanctuary throughout the year except for the monsoon season of October and November.
