The Upper Mustang Walled Kingdom Trek
The Upper Mustang Walled Kingdom Trek (14 Days) is a rare pilgrimage into one of the most culturally preserved, geographically dramatic corners of the Tibetan plateau. Known as the Kingdom of Lo, this semi-independent monarchy remained strictly closed to outsiders until 1992. Situated north of the main Himalayan spine in the rain shadow of Dhaulagiri and Annapurna, Upper Mustang boasts a moon-like desert landscape of eroded sandstone pillars, deep river canyons, ochre cliffs, and fortified white-washed stone villages.
The crown jewel of the expedition is the 15th-century walled capital of Lo Manthang (3,840m), founded by the warrior king Ame Pal. Here, ancient Tibetan Buddhist monasteries such as Jampa Gompa, Thubchen Gompa, and Chode Gompa safeguard 600-year-old silk thangkas and gold-inscribed murals. Venture into the multi-story cliff dwellings of Chhoser (Jhong Sky Caves), marvel at the blood-red cliffs of Dhakmar, and receive blessings at Ghar Gompa, one of the oldest surviving Nyingma monasteries in the world.

Frequently Asked Questions
Direct answers from our senior expedition leaders covering Upper Mustang permits, Lo Manthang culture, and weather.
Is the $500 USD Upper Mustang RAP permit included in the package price? +
Yes, 100%! The official $500 USD government Restricted Area Permit (covering 10 days in Upper Mustang), plus the Annapurna Conservation Area Permit (ACAP) and TIMS card are fully included in our package price.
Can solo travelers join this trek? +
Yes. Government regulations require a minimum of 2 trekkers to issue Upper Mustang RAP permits. We pair solo travelers with our confirmed departure groups to fulfill the government requirement seamlessly.
Why is Upper Mustang called the best monsoon / summer trek in Nepal? +
Upper Mustang is geologically situated on the Tibetan Plateau, in the rain shadow of Annapurna and Dhaulagiri. The 8,000m peaks block all monsoon clouds, meaning Upper Mustang receives less than 200mm of rain per year. June, July, and August are dry, sunny, and warm.
What are the Chhoser Sky Caves and how do we visit them? +
The Chhoser caves are over 2,000-year-old multi-story cave dwellings carved into vertical rock faces. During our exploration day from Lo Manthang, we hike or take a short ride north to enter Jhong Cave and explore its interconnected rooms, windows, and ladders.
What is the Tiji Festival in Lo Manthang? +
Tiji (Tenchi) is a 3-day sacred festival held every May in the courtyard of the King's Palace in Lo Manthang. Monks perform sacred masked dances celebrating the victory of the deity Dorje Jono over evil demons. We offer special fixed departure dates for Tiji.
What is Ghar Gompa and why is it famous? +
Ghar Gompa in Gyakar was built in the 8th century by Guru Padmasambhava. According to Tibetan Buddhist tradition, anyone who makes a sincere spiritual wish inside Ghar Gompa will have it granted.
How difficult is the Upper Mustang trek? +
It is graded moderate (3/5). Maximum altitudes reach 3,840m at Lo Manthang (4,010m on Nyi La Pass). The trails feature gentle ascents and descents without extreme passes, making it very accessible for all fit hikers.
What happens if Jomsom flights are delayed due to weather? +
If morning flights between Pokhara and Jomsom are affected by weather, we have backup private 4WD Scorpio jeeps on standby to transfer you safely along the Kali Gandaki highway.
How does the 15% flexible deposit work? +
You pay 15% ($283) online to secure your restricted permit reservation and flights. The remaining 85% is paid upon arrival in Kathmandu. Deposits have lifetime validity with free date changes up to 30 days prior.
What meals and water are provided on the trek? +
Full board (Breakfast, Lunch, Dinner) is included for all 14 days on trek. Menus offer Dal Bhat, Tibetan bread, momos, noodle soups, porridge, eggs, potato stews, and hot tea.
How windy does it get in Upper Mustang? +
The Kali Gandaki gorge creates thermal winds from 11:00 AM to 4:00 PM daily. We start trekking early in the morning (around 7:30 AM) to finish daily walking before the peak afternoon breeze.
What equipment is provided free by Best Treks Nepal? +
