Chimmony Wildlife sanctuary is in Mukundapuram Taluk of Thrissur District. Established in 1984, the sanctuary with an area of about 100 sq. kms is on the Western slopes of the Nelliyampathi hills. The forests here are Tropical Evergreen, Semi-Evergreen and the Moist Deciduous forests.

These forests which were once extensive and extremely thick, have been over the years been denuded by continuous over exploitation. The sanctuary makes for a wide variety of flora still. All major species of fauna of peninsular India are well represented in the sanctuary. However, due to years of human interference, the fauna is sparse. Some minor wildlife and some elephants and Gaur are also seen occasionally. The sanctuary also offers trekking paths for the adventure traveller.
