Mustang is located in the western part of Nepal and is officially the name of the district having a Tibet like region. This mustang is divided into two parts Upper Mustang and Lower Mustang. Upper Mustang is largely occupied by Manangi people and goes up to the ancient capital of Lo Manthang. Whereas Lower Mustang covers the part of lower valley along the Kali Gandaki river. Mustang is the only district in Nepal with its own King. The citizens of Mustang call themselves Lobas. "Mustang" is a Tibetan lost valley and stands as a hidden treasure of Nepal. A vast breadth of rock; wilderness of huge proportions, Mustang opened only for selected organized groups since 1992. Mustang offers a truly outstanding opportunity to travel around an area rich in ancient tradition and mythology. An almost treeless, barren landscape with a countryside similar to Tibetan plateau. In lower Mustang the hills tend to be great, red fluted cliffs, while upper Mustang offers an endless expanse of yellow and gray rolling hills, eroded by the wind, which is prevalent in this area. The trek takes you to the walled town of Lo-Manthang, a visually extraordinary place, home of the present Mustang's King and full of beautiful temples and Gompa.
