Covering an area of 932 sq. kilometres, the park includes hilly areas of the Shivalik Range covered by deciduous trees. Parts of the park are floodplains of the rivers; Narayani, Rapti, and the Reu. These floodplains are covered by dense tall elephant grass, forests of silk cotton, acacia and Sisam trees. Chitwan National Park was officially established in 1973 and included as a World Heritage Site in 1984. Journey down the river by canoe, watch the sunset over the jungle.
