The land of "Lo". Remote and forbidden to travellers for centuries, it is now open to trekkers. One will have the opportunity to witness their vibrant culture and also a chance to get a look at Lamaist Buddhism little changed by time. Mustang, or Lo Manthang, the desert plateau located in the upper valley of the River Kali Gandaki, and to the north of the main Himalayan range also falls in this region. Tourist access to Mustang is controlled to help retain its exclusiveness. The highlight of the trek includes the visit to the Mustang Palace, the visit to Lo Manthang and pony rides to the Nepal-Tibet border.
