The Chinnar Wildlife Sanctuary is among the most visited tourist destinations in Kerala. The entire sanctuary is covered with dry thorny scrub forest, deciduous forests, riparian types, sholas and grasslands that are interspersed within hillocks, plains, rocks and cliffs. Owing to the fact that this region receives less rainfall, the flora and fauna found here are mostly unique to the thorny vegetation.
The sanctuary is situated in the rain shadow area of the Western Ghats and therefore has almost a two-month long rainy season. In this deciduous forest, one can hope to spot the endangered Giant Grizzled Squirrel while enjoying a trek in the beautiful environs.
