Upper Mustang Trek: Journey to the Forbidden Kingdom of Lo
The Upper Mustang Trek offers a chance to explore one of Nepal’s most remote and culturally preserved regions. Known as the “Hidden Kingdom of Lo,” Upper Mustang features high-altitude deserts, red canyons, and ancient Tibetan-style villages that have changed little over centuries.
Upper Mustang remained closed to foreign visitors until 1992, which earned it the name “Forbidden Kingdom.” Today, trekkers can stay in local teahouses instead of camping, making the journey more accessible while still preserving the region’s traditional lifestyle and spiritual atmosphere.
Founded by Ame Pal in the 14th century, the Kingdom of Lo ruled for 25 generations. Because of its cultural and historical importance, Upper Mustang remains a restricted area, and trekkers need a special permit to enter.
The trail passes through dramatic landscapes shaped by wind and erosion, including red cliffs, deep canyons, and rock formations. You also travel through traditional villages such as Chhusang, Chele, Syangbochen, Ghami, Dhakmar, and Charang.
The trek’s main highlight is Lo Manthang, the historic walled capital. Here, you can explore narrow alleys, ancient monasteries like Namgyal Gompa, and the former King’s Palace.
If you visit in mid-May, you can experience the Tiji Festival, a three-day Buddhist celebration featuring masked dances and rituals performed by monks.
Along the way, the trek also offers wide views of Annapurna, Dhaulagiri, Nilgiri, and Tilicho Peak. Nyi La Pass (3,990 m) is one of the best viewpoints on the route, with panoramic views of Upper Mustang’s rugged landscape.
