The arid region at the end of the Kali Gandaki, beyond the Annapurna and Dhaulagiri is generally referred to as "Upper Mustang". The route entails traveling across a desert like landscape, making it a truly memorable trek. It is a land of barley field and pasture and vast expanses of grey and yellow rolling hills erode by the wind.

It is one of the strenuous treks offering a chance to explore the far west Dolpa region of the country. Shey Phoksundo National Park with an area of 3000sq. km. falls under this trekking area with a variety of flora and fauna. Deep dark forests, wide river canyons and gorges are additional spectacular sights.

It is an ideal trek for those interested in experiencing life style of different ethnic people and their cultures and explore a myriad of glaciers, high pass crossing and vast untracked foothills of the world's third highest mountain- the Kanchanjunga (8598m). The glacial deep in Kanchanjunga range provides the incredible panoramic view of other concentrated peaks and it could be a fitting reward of your effort.
