Mustang trek is an exploration of the concealed valleys of upper Mustang in Nepal, nestled between Tibet and the Himalayas – a place different from the rest of the world. The wall city of Lomanthang used to be a part of Tibetan kingdom of Gungthang until 1830s. The early history of Lomanthang is embellished in myths and legends rather than the recorded facts. Even though the upper Mustang is changing it still surprises the visitors with its stunning vista and the stubborn way it clings to its unique culture. Indeed, the culture is fighting back; crumbing art works are being restored. Crumbing monasteries have been rebuilt and refilled with the sound of bald-headed children in robes studying the ancient Buddhist ways. There are around 275 houses in Lo Mangthang having four castes: the royal caste, the everyday folk, the blacksmiths and the butchers and millers. The whole Lo manthang village has solar electricity now, along with a small herb garden of various holy decorations, flapping flags and of course stacked firewood. There was a time when it was the mandatory of certain family to supply the firewood for the royal family. Sky burial and polyandry are still remaining practice in this upper mustang region. Once Nepal got republic in 2005 the royal family is symbolic only. There is no any major effects or damage of April 2015 earthquake in the whole Mustang region – totally safe for trekking.

It is believed that Guru Rinpoche had fought with demon among the Mustang ‘s snowcapped mountain, desert canyons, and grassland. Once Guru Rinpoche killed the demon, it is said he scattered the demon’s body parts across Mustang valley: its blood formed the towering red cliffs and its intestines tumbled near to Ghami where people have later on build the stone prayer wall, the longest in Nepal, on top of the demon’s intestines.
