A walled city that held its own kingdom for six centuries. A desert plateau above the world’s deepest gorge. A corner of Nepal where Tibetan civilisation survived intact.

Upper Mustang was closed to foreign visitors until 1992. When Nepal opened the region it required a restricted area permit costing significantly more than any other trekking permit in the country, a deliberate policy to limit the volume of visitors and preserve the character of the place. The result, three decades on, is that Lo Manthang remains one of the most complete survivals of medieval Tibetan culture anywhere in the world. The walled city was built in the fifteenth century as the capital of the Kingdom of Lo. Its walls, its royal palace, its gompas, and the social structure of its community have endured in a form that the Chinese annexation of Tibet erased from most of the plateau further north.

The approach follows the Kali Gandaki, the deepest river gorge on earth by some measures, a corridor cut between Dhaulagiri and Annapurna through which the wind funnels south from the Tibetan plateau with enough force to make afternoon walking genuinely difficult. The landscape changes within a day of Jomsom: the monsoon vegetation of the lower valley gives way to the rain shadow desert of the upper gorge, the cliffs turning red and orange, the villages shifting from stone and timber to mud-brick compounds built into the hillsides. This is not Nepal as most visitors encounter it. It is a different country entirely.

Lo Manthang sits at 3,780 metres behind its encircling wall on a wide plain above the gorge. The wall is the first thing visible from the Nyi La pass on the approach: a band of white across the brown plateau, the buildings of the old city rising inside it. The royal palace is four storeys of mud-brick at the northern end. The gompas date from the fifteenth century and contain murals and thankas of exceptional quality. The king of Mustang still maintains a formal role in the community, though the legal status of the kingdom within Nepal changed in 2008. An audience with the royal household, when it can be arranged, is one of the more singular experiences available on any trekking expedition anywhere.

The eastern valleys beyond Lo Manthang hold the hermitages and cliff monasteries that represent the more solitary dimension of this region’s religious life. Luri Gompa is built into a cave in a cliff face, its frescoes maintained by a community that has used this site for centuries. Muktinath, at the southern end of the return route, is sacred to both Hindus and Buddhists: a temple complex where a natural gas seep produces a flame that burns above water, combining elements in a way that has drawn pilgrims for over two thousand years. The expedition ends in Pokhara and then Kathmandu, both of which feel, after the desert plateau of Mustang, enormously alive.

21 Days Through the Last Surviving Himalayan Kingdom

Days 1 to 3  |  Kathmandu

Arrive in Kathmandu and transfer to the hotel for the expedition briefing. The first three days are spent in the Kathmandu Valley, visiting the UNESCO World Heritage Sites that make the valley one of the densest concentrations of cultural monuments on earth. Swayambhunath on its hilltop above the city, Pashupatinath on the Bagmati river, the medieval Durbar Squares of Kathmandu, Patan, and Bhaktapur. These days are not simply preamble: the temples, the iconography, and the religious traditions visible in the valley provide the cultural context that makes Lo Manthang legible when the group arrives there. The restricted area permits for Upper Mustang are arranged during this time.

Days 4 to 8  |  Jomsom to Tsarang

Fly from Kathmandu to Pokhara and continue by small aircraft to Jomsom at 2,720 metres, the administrative centre of the Mustang district. The trek begins immediately into the Kali Gandaki corridor, the wind already present in the upper valley even in the morning. The trail north to Kagbeni passes through juniper scrub and red cliff formations before crossing the checkpoint into restricted territory. Above Kagbeni the landscape empties. The villages of Chele, Syangboche, and Ghami are mud-brick settlements built into the hillsides, their walls the same colour as the cliffs behind them. Lo Gekar, one of the oldest monasteries in Nepal, stands on a ridge above the trail. Continue to Tsarang, a substantial settlement below the last ridge before Lo Manthang.

Days 9 to 11  |  Lo Manthang

Cross the Nyi La pass at 3,950 metres to see Lo Manthang for the first time from above. The walled city sits on the plain below, its encircling wall visible from the ridge, the buildings of the old capital rising inside it. Spend two full days exploring the city: the four-storey royal palace at the northern end, the fifteenth-century gompas with their original murals and thankas, the narrow lanes between the mud-brick houses, and the daily life of a community that has maintained its traditions in this location for six centuries. An audience with the king and queen of Mustang is arranged when their schedule permits.

Days 12 to 16  |  The Eastern Valleys

Trek east from Lo Manthang into the remote valley system that few visitors explore. The cliff monastery of Luri Gompa is built into a cave in a vertical rock face, its interior containing frescoes that are among the finest surviving examples of fifteenth-century Tibetan Buddhist art. The village of Tangya, further into the eastern valleys, is small, largely self-sufficient, and receives almost no passing traffic. The return south to Muktinath crosses high ground above 4,000 metres with views across the upper Mustang plain to the Tibetan border ridges. Muktinath at 3,800 metres is the most important pilgrimage site in the region: a temple complex sacred to both Hindus and Buddhists, home to the eternal flame that burns above water through a natural gas seep.

Days 17 to 21  |  Pokhara and Kathmandu

Descend the Kali Gandaki back to Jomsom for a final evening with the expedition crew, a proper celebration of a journey that very few people complete. Fly to Pokhara for two nights on the shores of Phewa Lake, the Annapurna range reflected in the water to the north. Return to Kathmandu for the final day of sightseeing in the valley before the international departure.

Day by Day

Days 1 to 3  Kathmandu  The Medieval Gateway

Arrive at Tribhuvan International Airport and transfer to the hotel with a welcome from the SherpaHolidays team. The expedition briefing that first evening covers the full 21-day itinerary: the restricted area protocol for Upper Mustang, the cultural conventions appropriate for Lo Manthang and its royal household, the altitude profile of the trek, and the logistical arrangements for the internal flights. The briefing also introduces the cultural context of the journey: the history of the Kingdom of Lo, the Tibetan Buddhist traditions that define the region, and the specific religious sites the group will visit. Guests come to breakfast the following morning knowing clearly what the coming three weeks will involve.

Kathmandu is not simply a staging point for this expedition. The valley contains seven UNESCO World Heritage Sites and a depth of living religious culture that is directly continuous with what the group will encounter in Mustang. Swayambhunath sits on a hilltop above the western edge of the city, its whitewashed stupa and the eyes painted on its tower watching over the valley from a site that has been a centre of Buddhist practice for over two thousand years. Pashupatinath on the Bagmati river is the most sacred Hindu temple in Nepal, its ghats and its courtyards carrying the continuous activity of a site where the dead are cremated and the living come to pray in equal measure. The Durbar Squares of Kathmandu, Patan, and Bhaktapur are medieval royal court complexes in various states of preservation and ongoing life. The stone carvings, the timber lattice windows, and the pagoda temples of the Newari architects who built them represent a tradition of religious art that has been producing work of exceptional quality for over a thousand years. The restricted area permits for Upper Mustang are processed during these three days, allowing the group to move north without administrative delay on arrival in Jomsom.

Stay: Luxury Hotel in Kathmandu

Days 4 to 8  Jomsom to Tsarang  The Desert Plateau

The flight from Kathmandu to Pokhara and then to Jomsom is one of the more dramatic approaches to a trekking region in Nepal. The aircraft from Pokhara climbs north over the Annapurna foothills and then turns west through the gap in the main range, the great walls of Dhaulagiri and the Annapurna massif visible on both sides before the aircraft descends into the wide valley of the Kali Gandaki and lands at Jomsom. The airstrip here is at 2,720 metres and the wind is already present in the upper valley by mid-morning. This is the wind that defines life in the Mustang corridor: a thermal flow that funnels south through the gap between the two great massifs, strong enough in the afternoons to make walking slow and uncomfortable. The morning hours are the trekking hours in this valley.

The trail north from Jomsom to Kagbeni follows the river through a landscape that changes with every kilometre. The lower valley is still green in the monsoon season, juniper and scrub growing on the lower slopes, the river grey with glacial silt. By Kagbeni, the last village before the restricted zone checkpoint, the vegetation has thinned and the cliffs have begun to show the red and orange colouration of the upper desert. The checkpoint at Kagbeni is where the restricted area permit is verified. North of it, the trail enters a different country. The villages above Kagbeni are mud-brick settlements the colour of the hillsides they sit against, their flat roofs and enclosed courtyards built for a climate of cold winters and almost no rainfall. Lo Gekar monastery stands on a ridge above the valley above Ghami: one of the oldest religious institutions in Nepal, its foundation attributed to Padmasambhava, the eighth-century master who brought Buddhism to Tibet. Continue south of Tsarang for camp at one of the finest positions on the route, the red cliffs of the eastern wall above and the trail to Lo Manthang visible on the ridge ahead.

Stay: Traditional Mountain Lodges

Days 9 to 11  Lo Manthang  The Walled City

The Nyi La pass at 3,950 metres is a short but steep climb from Tsarang, and the view from the top is the one that justifies every step of the approach. Lo Manthang sits on the plain below: a rectangle of white wall enclosing the buildings of a city that has been in continuous occupation since the fifteenth century. The plain around it is brown and flat, the mountains of Tibet visible on the northern horizon, and the city in the middle of it all looks precisely like what it is: a walled capital built to be seen from a distance, its walls a statement of permanence in a landscape that otherwise offers none.

The city inside the wall is smaller than the wall suggests from above, its lanes narrow and its buildings close together in the way of settlements that were planned around defence as much as convenience. The royal palace at the northern end is a four-storey structure of mud-brick and timber that has been the seat of the Lo royal family since the kingdom was founded. The gompas of Lo Manthang are the reason that art historians and religious scholars have been making the journey here since the restricted zone opened: Champa Lhakhang and Thugchen Gompa contain original fifteenth-century murals and thankas of a quality and completeness that has survived here precisely because the isolation that made Lo Manthang difficult to reach also protected it from the destruction and looting that affected most comparable sites on the Tibetan plateau during the twentieth century. A local guide accompanies the group through the gompas on both days in the city, providing context that a self-guided visit cannot offer.

An audience with the King and Queen of Mustang is arranged through the SherpaHolidays team when the royal household’s schedule permits. The Kingdom of Lo lost its formal legal status within Nepal in 2008, when the country’s new constitution ended the recognition of hereditary monarchies. The royal family remains in Lo Manthang and continues to hold a respected ceremonial and cultural role in the community. An audience is not a tourist attraction. It is a formal meeting with a family that has governed this place for twenty-five generations, and it is conducted with the corresponding courtesy on both sides.

Stay: Local Lodge and Professional Tented Camp

Days 12 to 16  Luri Gompa to Muktinath  The Hidden Valleys

The eastern valleys beyond Lo Manthang are the least visited part of an already rarely visited region. The trail leaves the city through the eastern gate and crosses open plateau toward a valley system that drops into a series of narrow gorges cut through the red sandstone of the upper Mustang geology. Luri Gompa appears in the cliff face above the valley floor as a cluster of painted facades built across the mouth of a cave, the cave itself containing a temple and a chorten that archaeologists have dated to the fourteenth century. The interior murals are in a state of preservation that the altitude and aridity of this region make possible: the pigments still vivid, the figures still legible, the composition still coherent. Very few people see these paintings each year. The monastery is maintained by a small community whose commitment to preserving what is inside is evident in the condition of what remains.

The village of Tangya is further into the eastern valleys, a small community that the main trekking traffic does not reach. The people here are Loba, the traditional inhabitants of Lo, and the village functions on the same seasonal rhythms it has followed for centuries: agriculture in the summer, trade in the autumn, the long cold of the winter. The return south from Tangya crosses high ground above 4,000 metres with clear views across the upper Mustang plain to the ridges of the Tibetan border, then descends to rejoin the Kali Gandaki corridor for the final approach to Muktinath.

Muktinath at 3,800 metres is a religious site of a different order from the gompas of Lo Manthang. It is sacred to both Hindus and Buddhists, which is unusual in a region where the two traditions generally maintain separate institutions and pilgrimage routes. The sacred character of the site comes from a natural phenomenon: a gas seep that produces a flame burning above water, fire and water in the same place at the same time, which has been interpreted as a divine sign by both traditions for over two thousand years. The 108 water spouts arranged around the temple precinct are used for ritual bathing by Hindu pilgrims who believe the water carries purifying power. The gompa above the spring serves the Buddhist community. Both are in active use on any given day of the pilgrimage season.

Stay: Professional Tented Camp and Lodge

Days 17 to 21  Jomsom to Kathmandu  The Return

The descent of the Kali Gandaki from Muktinath to Jomsom is a single long day on a trail that the wind makes easier going south than it was going north. The vegetation returns gradually as the altitude drops: first the scrub juniper, then the larger trees of the middle valley, then the green of the lower slopes approaching Jomsom. The final evening in Jomsom is the traditional expedition dinner, the full crew gathered for a meal that marks the end of the mountain section and the beginning of the return. The connection between a group and the people who have carried the loads and cooked the meals and kept the camp for three weeks is one of the less expected rewards of this kind of travel.

The flight from Jomsom to Pokhara retraces the dramatic mountain approach of Day 4 in reverse, the great walls of Dhaulagiri and Annapurna flanking the aircraft as it turns south through the gap. Pokhara at 800 metres feels, after two weeks above 3,500 metres, warm and dense and extravagantly green. Two nights on the shores of Phewa Lake with the Annapurna range reflected in the water to the north is a considered end to the high-altitude section of the expedition rather than a rushed transit. The final flight back to Kathmandu returns the group to the valley where the journey began, the UNESCO temples and the medieval courtyards available for a final day of unhurried exploration before the international departure.

Five Things That Define This Journey

Lo Manthang: A City That Survived

The walled city of Lo Manthang was founded in the fifteenth century as the capital of the Kingdom of Lo, and it has been in continuous occupation since. While the Tibetan plateau to the north lost most of its historical monasteries and royal institutions during the twentieth century, Lo Manthang’s isolation preserved what it contained: the royal palace, the gompas, the murals, the traditions, and the social structure of a Himalayan kingdom. Walking through the lanes of the old city is walking through a place where the connection between the present and the medieval past is not curated or reconstructed. It is simply still there.

The Kali Gandaki Corridor

The Kali Gandaki river cuts between Dhaulagiri at 8,167 metres and Annapurna at 8,091 metres in a gorge that is, by the measure of the depth between river and adjacent summit, the deepest in the world. The trail north through this corridor is a walk through a landscape that changes from green Himalayan valley to red desert plateau within a day’s walking, the wind accelerating up the funnel between the two great massifs until the afternoons are genuinely difficult to move through. The red cliff formations of the upper valley, the abandoned cave dwellings cut into the faces above the trail, and the mud-brick villages that appear without warning in the hillsides are unlike anything on the standard Nepal trekking circuits.

Luri Gompa and the Cliff Monasteries

The cave monasteries of the eastern Mustang valleys represent a tradition of religious retreat that places the practitioner as physically far as possible from the world below. Luri Gompa is built across the face of a cave in a cliff, its fourteenth-century murals maintained in a state of preservation that the low humidity and extreme altitude of the region make possible in few other places on earth. The paintings inside belong to a period and a style that has been largely destroyed elsewhere. Seeing them in their original setting, in a functioning monastery reached by a trail that very few people walk each year, is an encounter with religious art that no museum visit can replicate.

Muktinath: Where Two Faiths Meet

The pilgrimage site of Muktinath at 3,800 metres is sacred to both Hindus and Buddhists in a way that is not merely a matter of shared geography but of genuine theological significance to both traditions. The natural gas seep that produces a flame burning on water at the centre of the site has been interpreted by both faiths as a manifestation of divine power for over two thousand years. Hindu pilgrims bathe in the 108 water spouts arranged around the temple precinct. Buddhist pilgrims circumambulate the gompa above the spring. On a busy pilgrimage day, both communities are present simultaneously, conducting their separate practices in the same place. It is one of the rarer encounters available on any journey in Nepal.

The Landscape of the Rain Shadow

Upper Mustang sits in the rain shadow of the Annapurna and Dhaulagiri ranges, which block the monsoon moisture that defines the rest of Nepal’s summer. The result is a desert plateau at 3,000 to 4,000 metres with an annual rainfall measured in tens of millimetres, a landscape of coloured sandstone canyons, wind-shaped rock formations, and a sky that is clear and bright in a way that the monsoon cloud cover renders impossible south of the ranges. The Himalayan blue sheep and snow leopard inhabit the high ridges above the valley. The amber and red cliffs of the sculpted canyon country between Kagbeni and Lo Manthang are a geological phenomenon that the wind has been shaping for millions of years and continues to work on with each passing season.

Things Guests Ask Before Booking

Real questions, answered by people who have actually made these crossings.
  • Yes, and they vary by country. Nepal's visa is available on arrival for most nationalities. Tibet requires a special Tibet Travel Permit, arranged through us it cannot be obtained independently through us. Bhutan requires a Bhutan visa, which we handle as part of the booking process. India requires a tourist visa applied for in advance. We
    walk every guest through exactly what's needed for their specific journey, well before departure.

  • Every Beyond Nepal journey we offer can be adjusted in duration, pace, accommodation tier, specific sites, and rest days. If none of our fixed routes match what you have in mind, we can build a multi-country itinerary from scratch. That's not an upsell, it's actually how most of our returning guests book.

  • Flights from your home country to Kathmandu are not included, as these vary
    significantly by departure city, and we want you to book what works for your schedule and budget. All regional flights within the journey, Kathmandu to Lhasa, Kathmandu to Paro, and so on, are included unless your itinerary specifies otherwise. We'll confirm every included and excluded flight clearly before you book.

  • Autumn (September to November) and spring (March to May) are the strongest
    windows for most multi-country journeys. That said, each destination has its own rhythm. Tibet is best visited before the summer rains, Bhutan has a spring festival season worth planning around, and India's north is at its finest from October through February. When you book with us, we advise on the exact timing based on where you're going and what you want to see.

  • In Nepal, your journey is led entirely by our Sherpa team. In Bhutan, Tibet, and India, we work with trusted local guides who meet our standard people we've partnered with for years, who know their regions the way our Sherpas know the Himalayas. You will always have someone beside you who actually knows where they are.

  • We handle everything: permits, accommodations, inter-country transfers, regional flights, border crossings, and on-the-ground coordination in each country. The only thing you arrange independently is your international flight to Kathmandu. From the moment you land, it's ours to manage.
