Here is a look at the five tiger reserves of Tamil Nadu.

Anamalai Tiger Reserve

Carved out of the Anamalai hills, the tiger reserve falls within the Western Ghats, which in itself is one of the 25 Global Biodiversity Hotspots. The reserve consists of diverse habitats, including tropical forests, shola jungles, bamboo groves and vast grasslands. It is known for its many endemic species of flora and fauna. Some of the key animals found here apart from the tiger are the gaur, sloth bear, elephants, pangolin, deer, and over 350 species of birds. Crocodiles can be spotted in the Amaravathy dam reservoir. One of the most interesting places inside the reserve is the Karianshola forest.

Coimbatore, the nearest airport, is about 75 km away. Pollachi, about 35 km away, is the nearest town and railway station. Topslip, one of the most scenic areas within the reserve, is the best place to visit. Topslip is about 40km from Pollachi.

In 2007-2008, the?Anaimalai region was declared as a tiger reserve.?Previously,?it was called the?Indra Gandhi Wildlife Sanctuary. This reserve shows the presence of a minimum of 15 tigers and co-predators.The forest remains open throughout the year, except during the peak monsoon season. Accommodation in the form of forest resthouses, dormitories, trekking sheds, among others, is available at various points, including Topslip, Valparai, Pollachi, and other areas. Visitors can avail vehicle and elephant safaris from Topslip. Trekking on specific routes may also be undertaken with the permission and services of a guide.

Kalakad–Mundanthurai Tiger Reserve

Popularly known as KMTR, this reserve was created in 1988 by combining the existing and contiguous Kalakad and Mundanthurai wildlife sanctuaries.
Kalakkad–Mundanthurai was declared as the first tiger reserve in Tamil Nadu. It occupies the southern part of the Western Ghats and consists of wet evergreen forests; it is the catchment area of 14 rivers. It is also part of the Agasthiyarmalai?Biosphere Reserve, which is considered one of the five centres of plant diversity and endemism in India by the International Union for Conservation of Nature (IUCN). Apart from tigers, the forest is home to sambar, spotted deer, elephants, leopards, wild dogs, and a large number of bird species, reptiles, and more.

The most convenient gateway to KMTR is through Tirunelveli, nearly 50 km from Mundanthurai and 45 km from Kalakad. Trekkers, with permission from the forest office and a guide, can explore the forest along specified routes. Forest rest houses are available at both Mundanthurai and Kalakad. The best time to visit is between October and March.

Mudumalai Tiger Reserve

The most popular tiger reserve in Tamil Nadu, it stands at the state’s border with Karnataka and Kerala. Surrounded by the ancient ranges of the Western
Ghat hills (the name "mudumalai" means "old mountains"), it is part of the Nilgiri Biosphere Reserve. The forest contains teak, rosewood, and other plants, apart
from meadows covered with tall elephant grass. Other than the tiger, some of the key animals include elephants, gaur, wild dogs, sambar, several kinds of deer and
the Malabar giant squirrel. There are more than 260 species of birds.

The reserve is about 240 km by road from Bengaluru, 90 km from Mysuru, and 68 km from Ooty. The tourist entry point, Theppakadu, lies off the interstate highway that connects the state’s popular hill-station Udhagamandalam (Ooty) with Mysuru?(in Karnataka). As the interstate highway cuts through the forests, you may sometimes find wild elephants standing in the middle of or leisurely crossing the road. Remember, animals have the right of way here and you have to wait patiently
till the elephants decide to go away. The alternative route from Ooty via the Kalhatti Ghat is shorter but has 36 hairpin bends along the way. The nearest towns are Gudalur and Masinagudi.

Forest department-managed lodging is accessible at Theppakadu, Masinagudi and Abhayaranyam. Permits for vehicle or elephant safaris into the forest must be
obtained from the Reception Range Office in Theppakadu. Between November and March is the greatest time to come.

Sathyamangalam Tiger Reserve

A tiger reserve since 2013, it forms an important corridor between the Eastern and Western Ghats through the Nilgiris. According to the 2019 census, it has an individual tiger population of 83 and a 111-individual leopard population. With?its strategic location, the tiger reserve is contiguous with other important protected areas, including BRT, Bandipur, Mudumalai?and Nagarahole. Part of the Nilgiri Biosphere Reserve, it is home to tigers, spotted deer, sambar, gaur, elephants, leopards, wild pigs, and other animals, including over 200 species of birds. The vegetation ranges from dry thorn shrubs to patches of semi-evergreen forests in the upper regions. The forest is also home to several indigenous tribes, including the Irula and Soliga people.

Srivilliputhur-Megamalai Tiger Reserve

The latest tiger reserve in the state, the Srivilliputhur-Megamalai Tiger Reserve (SMTR), was formed in February 2021 by combining the Megamalai and Srivilliputhur wildlife sanctuaries. It lies in the Western Ghats region. Srivilliputhur-Megamalai Tiger Reserve is Tamil Nadu's fifth tiger reserve and India's 51st. Srivilliputhur was well-known as the Grizzled Giant Squirrel Wildlife Sanctuary. Bengal tigers, elephants, gaurs, Indian giant squirrels, leopards, Nilgiri tahrs, and other animals can be observed here.

It’s a blend of tropical evergreen and semi-evergreen forests, dry deciduous and moist mixed deciduous woods, and grassland in this area. SMTR is also adjacent to the Kalakad-Mundanthurai reserve. The Srivilliputhur end is about 45 km from Virudhunagar town.
