The sanctuary is unique because it has more than 1000 different plant species, a majority of which are endemic to the area. Elephants, leopards, bison, sambars, wild boars, langurs, deer, etc., reside in this tropical semi-forest. Many endangered species, including the lion-tailed macaque and birds like the Great Eared Nightjar, can be seen here.
It is the only wildlife sanctuary in Kollam and is a part of the Agasthyamala Biosphere Reserve. Its name comes from the endemic tree species Gluta Travancorica, which is also referred to locally as ‘Chenkurinnji’. Here, you can find Myristica swamps, a special kind of vegetation. On the Parappar Dam in Shendurney, you can go boating, bird- and butterfly-watching, and hiking. The reservoir that the Thenmala Dam created completely encircles the region.
As part of the camping packages offered by Shendurney Ecotourism, the region offers overnight stays in specially constructed camping houses inside the forests. Idimuzhanganpara, Pallivasal and Rockwood are just a few of Shendurney's camping and trekking options. Options are available for hiking, jungle camping, jeep safaris and bird watching.
