Teesta River is a 414 km long river that rises in the Pauhunri Mountain of eastern Himalayas, flows through the Indian states of Sikkim and West Bengal through Bangladesh, and enters the Bay of Bengal. It flows through North Sikkim, East Sikkim, Pakyong District, Kalimpong district, Darjeeling District, Jalpaiguri District, Cooch Behar districts, and the cities of Rangpo, Jalpaiguri, and Mekhliganj. It joins River Brahmaputra at Fulchhari in Bangladesh. 305 km portion of the river lies in India and the rest in Bangladesh. Teesta is the largest river of Sikkim and the second largest river of West Bengal after the Ganges.
There are several River Rafting points on Teesta. Our driver recommended trying this one, which was en route to Gangtok, from Bagdogra. For many in our group, this was a first-time experience. Overall, it was totally fun and an exhilarating experience for all.
The color of the River is green due to the mechanical grinding of bedrock from dam constructions that releases fine particles of rock or “rock flour” into the water. When sediments enter the water, light wavelengths are distorted, reflecting green or blue light. In Teesta’s case, it is more of the green.
