Bardia National Park is located in the Far-Western Region, Nepal and was established in 1988 as Royal Bardia National Park. Covering an area of 968 km2 it is the largest and most undisturbed wilderness area in the Terai, adjoining the eastern bank of the Karnali River in the Bardia District.
The northern limits of the protected area are demarcated by the crest of the Siwalik Hills. The Nepalgunj-Surkhet highway partly forms the southern boundary, but seriously disrupts the protected area. Natural boundaries to human settlements are formed in the west by the Geruwa, a branch of the Karnali River, and in the southeast by the Babai River.
