Assam Himalayas, eastern section of the Great Himalayas, extending eastward across Sikkim state (India) and Bhutan, into northern Assam and Arunachal Pradesh states (India), and along the border with the Tibet Autonomous Region (China). The mountains run eastward for 450 miles (720 km) from the upper Tista River in the west to the great southward bend of the Brahmaputra River (there called the Tsangpo River) in the east. Important peaks include Kula, Chomo, and Kangto; the highest is Namjagbarwa (Namcha Barwa; 25,445 feet [7,756 metres]) in Tibet. The Subansiri, Manas, Sankosh, Raidak, and Jaldhaka rivers rise in the mountains and flow southward to join the Brahmaputra. Main settlements in the region include Gangtok and Kalimpang in India and Punakha and Paro in Bhutan. Important mountain passes include Natu, Jelep, and Tang.
