With around a hundred national parks, and more proposed, India offers some wonderful wildlife adventures and safaris. The heavily forested national parks of North India, such as Ranthambore and Corbett (the first national park in mainland Asia), and the vegetation rich national parks of Central India such as Kanha, Bandhavgarh, and Pench are best known wildlife. Some of the fascinating animals there are Asiatic elephants, tigers, gaurs (Indian bison), leopards, and the sloth bear - to mention but a few! Small populations of Great Single-horned Rhinoceros can be seen in several national parks, including Kaziranga National Park. A UNESCO World Heritage Site, Keoladeo Ghana National Park in Rajasthan, better known as the Bharatpur Bird Sanctuary, is an ornithologist's paradise. According to its website, the national park is home to over 230 species of birds. Gir Forest National Park is home to the endangered Asiatic Lions, the last population in the wild.
