Mustang is one of the recently opened areas for limited trekking groups each year. It was the former Buddhist kingdom of Lo, extended to the upper Kali Gandaki River which has carved the deepest gorge in the world between Dhaulagiri and Annapurnas. Mustang has a long and rich history that makes one of the most interesting places in Nepal. There are records of events in Lo as early as 8th century.

The trek follows the west side of Jomsom Valley with magnificent views of the Dhaulagiri, Nilgiri and the Annapurna massif from the pass at 4,000 meters and reaches the fabled madieval walled city of Lo Manthang full of cultural and religious heritage.

Not suffered from mass influx of tourists, the region has retained its unique and un-spoilt nature by less human impact in the area. The countryside of Lo Manthang is similar to Tibetan plateau with its endless expanses of yellow and gray rolling hills. A trek into this fabled forbidden kingdom of vast, arid valleys, eroded canyons, yak caravans, colorful-painted mud brick houses on the back dropped of majestic mountain of Nilgiri, Tukche, Annapurna and Dhaulagiri - a Shangri-La rich in spiritual reward with a culture insight into the primitive settlement of Buddhists whose life style remain unchanged for centuries can justifiably a very special one.
