Originating in a great glacier mass in the Kailas range of Himalayas, Brahmaputra is one of the major trans-boundary rivers of Asia. Originating in southwestern Tibet, it breaks through great Himalayan gorges into the Indian State of Arunachal Pradesh, where it is known as Dihang. In Assam Dihang is joined by several other tributaries to form the mighty and angry Brahmaputra River. From Assam it turns south to enter Bangladesh where it merges with Ganges to form the Padma River which eventually empties itself in the Bay of Bengal. Brahmaputra is the fourth largest river in the World travelling a distance of 2,880 kilometers through China, India and Bangladesh. Along with Brahmaputra River, there are several other smaller tributaries over which boat-cruising activities are fast developing within Assam. The state government tourism department has initiated a number of steps to promote such activities, including a recently launched pedal and motor boating cruises on the Kolong River near Nagaon. Numerous private cruise operators are also offering a variety of Brahmaputra Cruise packages which is definitely an exciting way of witnessing Assam.
