Mustang has a long, rich and complex history that mskes it one of the most interesting place in Nepal.The early history of Lo is Shrounded in legend. Myth and mystery,But there are records of events in Lo as early as the 8th century. It is quite likely that the Tibetan poet Milarepa, who lived from 1040 to 1123, visited Lo. Upper Mustang was once part of Ngari, a name for far western Tibet.Ngari was not a true political entity, but rathere a loose collection of feudal domains that also included parts of Dolpo.By the 14th Century, much of Ngari, as well as most of what today is western Nepal, was part of the Malla empire governed from the capital at Sinja, near Jumla.It is generally belived that Ame Pal (Ama-dpal in Tibetan ) founded Lo in 1380 and was its first king. The Ancestry of the present Mustang Raja can be traced 25 generations back to Ame Pal. Ame Pal, or perhaps his father, conquered a large part of the territory in the upper Kali Gandaki and was responsible for the development of the city of Lo Manthang and many gompas.

Completely closed to foreign trekkers until 1991, Mustang is an ancient Himalayan Kingdom. Inside the walled city of Lo Manthang are some of the largest Tibetan Buddhist gompas in Nepal. A difficult trek because of high altitude, exposed terrain and continual Strong winds.
