Mustang Trek is the region of Tibetan influence north of Kagbeni Village is generally referred to as Upper Mustang Region. The ancient Kingdom of Mustang – the capital Lo- Manthang was attached to Tibet in the 14th century. Upper Mustang Trek is retained its identity as an autonomous dynasty throughout the centuries - is a walled city with their own present King – Jigme Prabal Bista and the people still remain predominantly Tibetan. Mustang Trek is still restricted zone of Nepal (special permits are required). Mustang Trekking to Lo-Manthang (3730 m) refers to the arid Tibet-like region at the northern end of Kali Gandaki. Upper Mustang trek to Lo- Manthang is through an almost treeless barren landscape. Strong winds usually bowl across the area in the afternoon, generally subsiding at night. Annexed by Nepal in 17 century, but untouched by the outside world or the Chinese Cultural revolution, 14th century monasteries still remain active to preserve this magnificent Trans-Himalayan kingdom, with their unrivalled Buddhist shrines with cliff hanging monasteries, Thankas, Mandalas and deities and cave dwelling people. In this wild lunar landscape of unreal color and beauty, ruggedly carved mountains reach up to deep blue skies, while icy peaks glimmer majestically to the south. Vast and barren ridges extend to the northern horizon making one feel like an insignificant dot on a timeless landscape. Often described as the hidden or lost Tibetan kingdom, Nepal’s Mustang presents one of the last intact vestiges of Tibetan Buddhist religion, culture and lifestyle unchanged in centuries. Trekking to Mustang is a journey beyond the Himalaya, a journey to one of the most remote kingdoms on earth. Starting at Jomsom in the Kali Gandaki valley, the trek passes through a barren, desolate landscape carved deep by cayons, until the walled capital city of Lo Monthang is reached. Filled by a maze of narrow lanes and streets, the city presents a medieval setting with its ancient place, monasteries, and temples. This is an amazing experience that allows one to step back in time.
