The Bardia National Park is spread over 968 sq. km. and located in the western Nepal Terai. It is easily the largest and least disturbed wilderness spread in the terai and is predominantly sal forest sprinkled with tall grasslands. It is bounded on the north by the Churia Hills and is skirted on the west by the Geruwa River. It is here that your chances of spotting a tiger in Nepal are the highest. Other animals include the rhinoceros, swamp deer, leopard, jungle cats, blue bulls, sloth bear, barking deer, and languor. There are a few wild elephants and some of the males are considered the largest in Asia.
The Geruwa River that rushes in through a break in the hill range, is home to the famous masher game fish, gharial, marsh mugger crocodiles and the freshwater Gangetic dolphins. The park also has cobras, kraits and pythons.
The park boasts more than 250 species of birds, including the endangered Bengal florican, Sarus crane and many species of geese, duck and parakeets.
