Assam Himalaya is a traditional designation for the portion of the Himalaya range between the eastern border of Bhutan, on the west, and the Great Bend of the Tsangpo River, on the east. The highest peak of this range is Namcha Barwa. Other high peaks include Gyala Peri, sister peak to Namcha Barwa; Kangto, and Nyegyi Kansang. The area is still poorly surveyed in general, and little visited by outsiders.
