The Upper Mustang Trek is one of Nepal’s most fascinating and culturally rich journeys, offering a rare glimpse into the ancient Himalayan kingdom of Lo-Manthang, once forbidden to outsiders. Known as the “Last Forbidden Kingdom,” Upper Mustang lies in the rain shadow of the Annapurna and Dhaulagiri ranges, creating a unique desert-like landscape unlike any other trekking region in Nepal.
This trek combines spectacular mountain scenery, deep canyons, ancient caves, and centuries-old Tibetan culture that still thrives untouched by modern influence. For travelers seeking both adventure and cultural immersion, the Upper Mustang Trek is an unforgettable experience.
Overview of the Upper Mustang Region
Upper Mustang, often called “The Kingdom Beyond the Himalayas,” was opened to trekkers only in 1992. The region retains its distinct Tibetan heritage, preserved for centuries due to its isolation. The capital, Lo-Manthang, is home to whitewashed mud-brick houses, monasteries, and royal palaces that reflect the spiritual and architectural legacy of ancient Tibet.
The Upper Mustang Trek is more than just a trek—it’s a journey through time, where trekkers witness how life once was in the remote Trans-Himalayan region. The rugged cliffs, barren hills, and colorful rock formations create a mesmerizing contrast against the backdrop of snowy peaks.
Trekking Route and Major Highlights
The Upper Mustang Trek usually takes 12 to 15 days, beginning with a flight from Pokhara to Jomsom, the gateway to Mustang. From there, trekkers follow the Kali Gandaki River northward through windy valleys, ancient villages, and high desert plateaus leading to the walled city of Lo-Manthang.

Cultural and Spiritual Experience
The Upper Mustang region is deeply influenced by Tibetan Buddhism. The people of Mustang, known as Lobas, practice age-old traditions passed down through generations. Trekkers encounter chortens, mani walls, and prayer flags fluttering in the wind, symbolizing the deep spirituality of the land.
Lo-Manthang, the spiritual and cultural heart of Upper Mustang, feels like an open-air museum. Its monasteries (gompas)—such as Jampa Lhakhang, Thubchen Gompa, and Chode Gompa—house ancient murals, thangkas, and relics. The annual Tiji Festival, a three-day celebration, showcases sacred dances and rituals depicting the victory of good over evil.
Unlike other trekking regions in Nepal, Mustang’s Tibetan-like culture and traditional way of life remain remarkably preserved, offering a rare cultural authenticity.
Unique Landscape and Natural Beauty
Upper Mustang’s landscape is unlike the lush greenery of the Everest or Annapurna regions. Instead, it features arid canyons, eroded cliffs, and multi-colored rock formations sculpted by wind and time.
The Kali Gandaki River Valley cuts through the heart of the region, creating one of the deepest gorges in the world. Trekkers walk along dry riverbeds and sandy trails surrounded by towering red and orange cliffs that glow under the Himalayan sun.
Despite its desert-like environment, the region’s stark beauty and spiritual aura make it one of the most photogenic trekking destinations in Nepal. Every turn reveals a new landscape—vast plains, hidden caves, and distant snow-capped mountains.
Best Time for the Upper Mustang Trek
The best seasons for trekking in Upper Mustang are spring (March–May) and autumn (September–November).
However, because it lies in a rain shadow region, Upper Mustang can also be trekked during the monsoon season (June–August), making it one of the few treks in Nepal suitable year-round.
- Spring: Clear skies, warm days, and the famous Tiji Festival.
- Autumn: Mild weather and excellent visibility.
- Monsoon: Fewer trekkers and unique colors across the dry landscapes.
- Winter: Harsh and cold; some teahouses may close.
Trek Difficulty and Preparation
The Upper Mustang Trek is graded as moderate. It does not require technical climbing, but trekkers should be in good physical condition due to long walking days and altitude gain up to 4,200 meters.
Most trails are dry and windy, with steep ascents and descents between passes. Regular hiking, cardio exercises, and strength training before the trek can greatly help endurance.
Hiring an experienced guide and porter is mandatory since Upper Mustang is a restricted area.

To trek in Upper Mustang, trekkers must obtain the following permits:
- Restricted Area Permit (RAP): USD 500 per person for 10 days (additional USD 50 per day beyond 10 days).
- Annapurna Conservation Area Permit (ACAP): NPR 3,000.
Solo trekking is not allowed; you must trek with a registered guide and through a government-authorized trekking agency.
Accommodation and Food
Accommodation along the Upper Mustang Trek is in local teahouses offering basic rooms and hearty meals. The teahouses are simple but comfortable, often built from local stone and mud.
Meals typically include dal bhat (rice and lentils), noodles, Tibetan bread, momos, and yak butter tea. In Lo-Manthang, some lodges even offer Wi-Fi and hot showers, providing comfort after long trekking days.
The warm hospitality of the local people makes every stay memorable.
