Mustang was an important route of crossing the Himalayas between Tibet and Nepal. Many salt caravans travelled through Mustang in the old times. Once a major thoroughfare for the trade of salt and grain between Tibet and Nepal's southern hills, the Mustang District in Nepal's western Himalayas remains a trading route to this day. For centuries, caravans travelled along the Kali Gandaki river trading salt, yak wool, cereals, dried meat spices and more in Tibet, China and India. and the Kali Gandaki gorge was used as a trade route between India and Tibet for centuries. The mountain pass of Kora La is one of the oldest routes between the two regions. It was historically used for salt trade between Tibet and Nepalese kingdoms.
