The Kingdom of Mustang is one of the most remote and isolated region of Nepalese Himalaya. Once an independent Buddhist kingdom, Mustang was annexed by Nepal at the end of the 18th century.
The landscape is also unlike anything that is to be found anywhere else in Nepal - deep gorges carved by the Kali Gandaki River, and strangely sculptured rock formations. The cliffs' face are pitted with an estimated 10,000 ancient cave dwellings, some of which are perched more than 150 feet above the valley floor. No one knows who dug them, or how people even scaled the near vertical rock face to access them.
