Nagarhole National Park, also known as 'Rajiv Gandhi National Park,' is located 94 km from Mysore. It is spread between Kodagu and Mysore districts. The exclusive hunting reserve of the former rulers of Mysore, the park has rich forest cover, small streams, valleys, and waterfalls. In 1975 its area stretched to 575 km².

The place derives its name from Kannada, Naga meaning snake and hole meaning stream. Set up in 1955, it is one of the best-managed parks in the country. The climate is tropical; summer is hot and winter is pleasant. The park boasts a healthy tiger-predator ratio, and tiger, bison, and elephant are much more populous here than in Bandipur.

The park is part of the Nilgiri Biosphere Reserve. The Western Ghats, Nilgiri Sub-Cluster (6,000+ km²), including all of Nagarhole National Park, is under consideration by the UNESCO World Heritage Committee for selection as a World Heritage Site.
