Nagarhole National Park, the enchanting 247 square-mile park in Karnataka has an astonishing abundance of wildlife including large mammals such as tiger, leopard, wild elephant, Dhole (Indian wild dog), and Gaur (Indian bison).
The park derives its name from the combination of two Kannada words. 'Naga,' meaning snake, and 'hole,' meaning streams. True to its name, quite a few serpentine streams fork through the rich tropical forests of the park. The landscape is one of gentle slopes and shallow valleys. Dry deciduous forest trees are leafless in the summer rather than in the winter. There are grassy swamps where the soil is clayey, perennially moist, and which support a luxuriant growth of green grass all year. The change in terrain throughout the park in refreshing and the river system provides a unique wildlife viewing experience. The park has been recently renamed as Rajiv Gandhi National Park after the late Prime Minister of India.
