It is situated about 80 km north-west of Coimbatore in the westernmost part of Tamil Nadu, on the interstate boundaries with Karnataka and Kerala states in South India. The park was created in 1940 to become the first wildlife sanctuary in southern India. Originally 60 square kilometres, the sanctuary was enlarged to 295 km² in 1956 and subsequently to its present size of 321 km². The sanctuary is contiguous with Bandipur National Park (874 km²), Wynad Wildlife Sanctuary (344 km²), Sigur and Singara reserve forests. The park is part of the Nilgiri Biosphere Reserve.
There are as many as 37 Tigers in Mudumalai forest area, whereas the Leopard is most often seen in the Kargudi area. Other carnivores include the Striped Hyena (Hyaena hyaena), the Golden Jackal and the Sloth Bear and the Asian Elephant.
