The highlight of any tourists stay at Nisargadama can be the three-kilometer walk around the island, along the river. Dewdrops hang like fresh pearls, glistening in the morning sun, on the webs of wolf spiders. Many varieties of butterflies can be seen flitting around. A pied Maratha woodpecker can put up an appearance, followed by a Rufous woodpecker. Flocks of blossom-headed parakeets flit from treetop to treetop, calling to each other constantly.
Lorikeets join in the cacophony.
Crimson-colored scarlet minivets and nuthatches can be spotted too. From across the river one can hear the drum beat-like calls of a crow pheasant. The river itself is a major attraction. Here the Kaveri is rapid, unlike in the plains and is a river of many moods. In addition to the myriad life forms in the water, the river sustains a vast network of terrestrial creatures Nisargadama gives you an idea of a riverine forest, the kind of forest that once clothed the banks of the Kaveri right from Kushalnagar to Salem.
