The evapo-transpiration from these forests is much higher than from any other surfaces. This cools the atmosphere, helps easy condensation of water vapour and thus causes the summer rains.
But sightings of these animals are all but assured. However, this place is ideal for watching other animals in their natural habitat. Other animals include elephant, wild pig, sambar, gaur, Malabar flying squirrel, stripe-necked mongoose and over 260 species of birds including blue-winged parakeet, Nilgiri wood pigeon, white-bellied tree pie, laughing thrushes and flycatchers. Located close to the border of the states of Kerala and Tamil Nadu, the park makes an ideal base to have a sojourn while undertaking long journey across the Ghats between Madurai and the coast. It's also a convenient place for excursion to the Cardamom hills, combined with the well known pilgrimage center of the Sabarimala, a couple of tea factories, spice plantations, and spectacular view of the forest waterfalls all of them a stone's throw distance.
