a)Mudumalai National Park

It shares its borders with Kerala and Karnataka and is separated from Karnataka's Bandipur National Park by the Moyar river.
The lowest point of the sanctuary is the picturesque Moyar Waterfalls. Its rich topography is as varied as the vegetation, which ranges from dense deciduous forests in the west to scrub jungles in the east interspersed with grasslands, swamps and bamboo brakes.
b)Guindy National Park
Originally a part of the private forest reserve surrounding the Guindy Lodge in the sub-urbs of Chennai, a portion of it was declared as theGuindy National Park in 1977 and is one of the very few national parks situated within a metropolis.
The park is the home to the endangered Blackbuck and the Spotted deer and has over 130 varieties of birds including raptors such as the honey buzzard and the white-bellied sea eagle. Bird-watching is popular in winter, when migrant birds visit the region. Also located within the park is the Snake Park where one can see the King Cobra, the Python among other reptiles.
For ex-situ conservation, about 22 acres (8.9 ha) of the Guindy National Park has been carved out into a park known as the Children's Park and play area at the northeast corner of the national park with a collection of animals and birds. The park attracts more than 700,000 visitors every year
