This is the first national park of Nepal established in 1973 to preserve a unique ecosystem significantly valuable to the whole world. The park covering a pristine area of 932 sq. km is situated in the subtropical inner Terai lowlands of the southern central part of Nepal. The park has gained much wider recognition in the world when UNESCO included this area on the list of World Heritage Site in 1984.

Formerly, the Chitwan valley was well known for big game and was exclusively managed as a hunting reserve for the Rana Prime Ministers and their guests until 1950. In 1963, the area south of Rapti was demarcated as a rhinoceros sanctuary. In 1970, His late Majesty King Mahendra had approved in principle the creation of Royal Chitwan National Park.
