The Royal Bardia National Park, situated in the mid far-western Terai, east of the Karnali River, is less developed than Chitwan and the largest untouched wilderness area in the Terai. The terrain is similar to that of Chitwan – forested hills and grassy flatlands cut by water channels. A former royal hunting preserve gazetted as a park in 1988, Bardia is inhabited by crocodiles, hordes of birds and nearly 50 species of mammals, including antelope, monkeys, leopards, jungle cats, sloth bears, blue cows and a thriving rhino herd from Chitwan. There are at least two wild male elephants, and one is believed to be the largest in Asia. Endangered bird species include the Bengal florican, lesser florican, silver-eared mesia and Sarus crane. Bardia also offers a better chance of seeing a tiger than any other place in Nepal. The Geruwa River, which rushes through the park, is home to the famous mahseer game fish, gharial and mugger crocodiles, and the strange Gangetic dolphin.
