River Kali is the largest and the most important river of the Kumaon region. It forms the border between India and Nepal, draining both Eastern Kumaon and Western Nepal. The Kali is fed by glaciers, some of which lie in Nepal and others in the Kali valley adjoining Lipulekh. Its many tributaries include Saryu, Gori, Kuti, Dhauli East and Ramganga East. Saryu is the largest tributary, which rises in the north-west area of Baijnath in Central Kumaon.
It merges with the Kali River at Pancheshwar. The temple town of Baijnath and Pancheshwar are important settlements along the Saryu River. The river flows through a fascinating environment that is home to a diversity of endangered species, and the best way to get a good glimpse of this is by rafting in the exhilarating rapids of the Kali. One will discover several species of very rare hornbills, monkeys, elephants, wild boars, sambar deer, crocodiles, giant squirrels and perhaps even leopards and black panthers.
