Manas National Park is spread over an area of 391 square kilometers in Assam. The name of the park is originated from the Manas River, which is named after the serpent god Manasa. The Manas river is a major tributary of Brahmaputra River, which passes through the heart of the national park.

The extremely popular Park is situated near the foothills of the Kamrup district. On 1st October 1928 it was declared a sanctuary and in December 1985 it was designated a World Heritage site. It was declared a national park in 1980. Project Tiger, Rhino and Elephant were launched here.

The vegetation in the Forest is primarily tropical moist deciduous type. The fast disappearing hispid hare needs swampy atmosphere to survive. You can see Khairsissoo-bhabhar grass, mul, khoir, udal, sida, bohera and kanchan trees in and around the park.

The focus point of Manas National Park is the enchanting Manas River, named after the serpent goddess Manasa. It is the largest Himalayan tributary of the mighty Brahmaputra. Coming down the Bhutan Hills from the north, the crystal clear waters of the Manas river runs through the heart of the 500 sq. km core area of Manas Park. The main tourist spot of Mothanguri, on the northern border of Manas with Bhutan, is situated on the banks of this river.
