Named after the famous prime minister Indira Gandhi, this sanctuary is also referred to as the Anaimalai Sanctuary at times. It is at the core of the Nilgiri Biosphere Preserve. A wide variety of exotic animals can be seen here. Such animals include panthers, tigers, elephants, spotted deer, civet cats, and wild boars. Numerous birds can also been seen here.
The black headed oriole, rocket-tailed drongo, tree pie, spotted dove, and red whiskered bulbul are all birds that you could very well spot while in the sanctuary. It is possible to see all of the sites in the park by trekking or by riding in a safari van. The best time to visit this sanctuary is during the months of December to April.
