TREK HIGHLIGHTS
- Trek through Humla, one of Nepal's least visited districts, and the Limi Valley, opened to outside trekkers only in the early 2000s.
- Follow the Karnali River along a centuries-old salt and pilgrimage trade route between Nepal and Tibet.
- Cross the Nara La (around 4,620 m), with views toward the Tibetan plateau.
- Cross the Nyalu La (around 4,940 to 4,950 m), the highest point of the trek.
- Spend time in Til, Halji, and Jang, three Tibetan-influenced villages where daily life still follows old patterns.
- Visit Halji's Rinchenling Monastery, one of the oldest Tibetan Buddhist monasteries in Nepal, close to 1,000 years old.
- See the Namkha Khyung Dzong Monastery in Yalbang, the largest monastery in Humla.
- Relax in the natural hot springs at Kermi, visited twice on this route, once on the way out and once on the way back.
- Walk into Hilsa, a Nepal-Tibet border village on the Karnali River, within sight of the checkpoint into China.
- Camp through a remote, largely unspoiled landscape, and plan around Simikot's weather-dependent mountain flights, which shape the pace of the whole trip.
Humla is the most remote district in Nepal, tucked into the far northwest corner of the country, hard against the Tibetan border.
Access to Humla is changing as new off-road routes gradually reach further into the region. Simikot is still the main gateway for air travel, but recent road development has opened an off-road connection toward Simikot, and vehicles are now also being used on sections toward the Hilsa checkpoint. Jeeps and tractors can be used for supplies and logistics along these rough roads.
For trekkers, however, the classic route remains a walking journey through remote valleys and old Himalayan trails. The changing road access is simply making some parts of Humla easier to reach and support than they were in the past.
Inside Humla lies the Limi Valley, a cluster of three villages, Til, Halji, and Jang, that sit closer in culture to Tibet than to Kathmandu.
People here speak Tibetan dialects, follow Tibetan Buddhist traditions, and live much as their ancestors did for centuries. The valley was closed to outside visitors until the early 2000s, so it has none of the tourist infrastructure found in places like the Everest or Annapurna regions.
The Humla-Limi Valley Trek is a 21-day route that follows the Karnali River out of Simikot, climbs over the Nara La into the border village of Hilsa, loops through Til, Halji, and Jang, and returns over the Nyalu La before dropping back down to Simikot.
Because the trail passes through areas with little or no lodging, this trek is organized as a camping trek, with tents, a cook, and full kitchen support carried along the route.
What sets this trek apart from Nepal's more established trekking routes is the remote landscape, the strength of Tibetan culture in the Limi villages, and the traditional way of life that has developed around the valley's connection with Tibet. Although road access is gradually changing parts of Humla, the Limi Valley itself still offers a very different trekking experience from Nepal's busier regions.
You will walk for days without seeing another trekking group, cross two high passes above 4,600 m, and spend nights camped in some of the quietest valleys in the Himalayas!
Why Trek Humla Limi Valley With HEN?
Running a trek like this takes more than a fixed itinerary. Humla has no road access, limited communication, and very little tourist infrastructure, so the route depends on careful planning long before the first flight to Simikot.
Our team at HEN handles the Restricted Area Permit and TIMS card in advance, since both are required to travel beyond Simikot and take time to process.
We also plan the camping side of the trek in detail, arranging tents, kitchen equipment, and a full cook and support crew who carry and set up camp each day, since most of this route has no lodges to rely on.
Our guides know the Humla and Limi trail well, including where water and camping grounds are reliable and how the two high passes usually behave in different seasons. Because flights in and out of Simikot are often affected by weather, we build a buffer day into the schedule and keep in contact with local flight operators so we can adjust plans if delays happen!
Food on the trek is prepared fresh by our kitchen crew at each camp, and we carry the gear needed to keep you comfortable through cold nights above 3,000 m.
If a problem comes up on the trail, our guides are trained to make the first call on next steps, whether that means rest, a change of pace, or arranging help from Simikot.
Important Note on Accommodation: Are There Teahouses on the Trail?
This is a common question, since some villages along the route do have very basic local guesthouses.
Places like Dharapuri, Kermi, Yalbang, and Tumkot sometimes have a small teahouse or homestay room, usually no more than a simple bed with shared, outdoor bathroom facilities.
However, this itinerary is organized as a full camping trek from Simikot to Simikot. In the Limi Valley villages of Til, Halji, and Jang, and at remote stops like Manepeme, Talung, and Shinjungma, reliable lodging does not exist, so camping is the only realistic option.
To keep the standard of accommodation, food, and hygiene consistent across all 21 days, we camp throughout the trekking section rather than mixing teahouse nights with camping nights.
You should expect a tent, a sleeping mat, and shared camp toilets set up by our crew each evening, with hot meals cooked fresh at every stop. Kathmandu, Nepalgunj, and Simikot are the exceptions, where you stay in a hotel with a proper room and bathroom.
Flights: What You Should Know
For the traditional trekking itinerary, access normally involves Kathmandu to Nepalgunj, Nepalgunj to Simikot, and the same route in reverse at the end of the trek.
Depending on your schedule and budget, you can also reach Nepalgunj by road from Kathmandu and use a charter or shared helicopter onward toward Simikot and Hilsa. The best option depends on whether you are travelling for the full trek, a pilgrimage, or a shorter visit to northern Humla.
The Kathmandu-Nepalgunj flight takes around 50 minutes and runs on standard domestic routes with few weather issues, since Nepalgunj sits in the lowland Terai.
The Nepalgunj-Simikot flight is the section that needs the most flexibility. Simikot's airstrip sits at around 2,950 m in mountain terrain, and flights here are often delayed or cancelled because of cloud, wind, or poor visibility, especially in the morning. It is common for flights to wait a few hours, or occasionally a full day, for conditions to clear!
Because of this, we recommend not booking your international flight home for the same day you plan to leave Simikot. Built-in flexibility, including the buffer day near the end of the trek, gives your schedule enough room to absorb a delay without missing your onward travel.
New Transport Options in Humla
Humla is becoming easier to access as road and transport links gradually develop. Recent off-road road sections have connected further toward Simikot, while the route from Simikot toward Hilsa and the border checkpoint is also being used for local transport, supplies, and logistics.
Jeeps and tractors are now used on some sections of these rough roads, although conditions can still be difficult and the road should not be confused with a standard paved mountain highway!
For the traditional Humla-Limi Valley Trek, you still fly into Simikot and continue on foot for most of the journey. However, these new transport links give the region more options than it had in the past.
The same route has long been important for people travelling toward Tibet for the Mount Kailash and Lake Manasarovar pilgrimage. Hilsa is a major access and exit point between Nepal and Tibet, and the route can also be important when pilgrims need to leave the Tibetan side because of altitude sickness or other health problems.
For travellers with limited time, helicopter travel is another option. Those who have a shorter schedule or prefer private helicopter travel can fly toward Simikot and Hilsa and reach the Lake Manasarovar pilgrimage area much faster than by following the traditional overland route.
Helicopter services can be arranged as private charters or shared flights, depending on availability and the travel plan!
A typical air-access option is to fly from Kathmandu to Nepalgunj, or drive to Nepalgunj if preferred, and then continue from Nepalgunj toward Simikot and Hilsa by charter or shared helicopter service. The exact routing depends on weather, helicopter availability, permits, and the purpose of the trip.
More About Importance of Buffer Days on This Trek
Day 19 of this itinerary is set aside as a buffer day in Simikot, and it exists for one main reason: flights between Simikot and Nepalgunj are unpredictable. Weather in the mountains can change quickly, and a delay of even a few hours can push a flight to the next day, or later.
This buffer day is not an extra trekking or sightseeing day built into the route. It is there so that if your flight out of Simikot is delayed, you still have time to reach Nepalgunj and Kathmandu before your international departure.
If the weather cooperates and flights run as planned, you simply have a relaxed day in Simikot before flying out.
Skipping this buffer to shorten the trip is not something we recommend. Humla's flight schedule is one of the least predictable in Nepal, and building in this flexibility is one of the most practical things you can do when planning a trip through this region!
Staying Safe on This Trek
The Humla-Limi Valley Trek passes through remote terrain, so a realistic understanding of the risks helps you prepare properly. The trail crosses two high passes, the Nara La at around 4,620 m and the Nyalu La at around 4,940 to 4,950 m, and altitude sickness is a genuine risk above 3,000 m if you climb too fast.
The itinerary is built with a gradual gain in altitude and rest points along the way, but you should still watch for symptoms like headache, nausea, or unusual fatigue, and tell your guide right away if you notice them. Drinking enough water, avoiding alcohol during the trek, and pacing yourself on the passes all help reduce the risk.
Mountain weather in Humla can change quickly, particularly around the Nara La and Nyalu La, so warm, waterproof layers and a good sleeping bag matter more here than on many other Nepal treks.
Distances between settlements are long in places, and some days have no village at all along the route, so following your guide's pace and instructions is important, especially on pass-crossing days!
Communication is limited once you are away from Simikot, and mobile networks do not reach most of the trail. Your guide carries means of contacting Simikot in an emergency, and it is worth confirming that your travel insurance covers high-altitude trekking and helicopter evacuation before you leave home, since rescue from this part of Humla would depend on it.
Flight delays out of Simikot can also leave you waiting longer than planned in a place with limited services, so packing a few extra days of medication and any personal essentials is a sensible precaution.
Main Attractions of Humla Limi Valley Trek
Here's what to expect on this 21-day adventure:
Humla and the Karnali River
As mentioned earlier, Humla is Nepal's most remote district, reachable only by air, and the Karnali River runs through nearly the whole length of this trek.
As Nepal's longest river, the Karnali carves a deep valley through Humla on its way south, and the trail from Simikot to Yalbang and beyond follows its banks closely, through pine forest, terraced fields, and narrow gorges.
The river has shaped where villages sit and how people here have farmed and traveled for generations!
The Ancient Salt Trade Route
Long before this became a trekking route, it was a working trade path between Nepal and Tibet. Salt, wool, and other goods moved along this trail by mule and yak caravan, and pilgrims heading toward Mount Kailash and Lake Manasarovar used the same route through Hilsa.
Walking this trail today follows the same line used for centuries, and the trade connection still shapes daily life in villages like Hilsa, where goods still move across the border.
Today, the same geographic connection with Tibet continues to shape the region. The Hilsa route remains important for pilgrimage, cross-border movement, and local supplies, while the newer road and transport links are gradually changing how goods and people move through Humla.
Simikot
Simikot is the administrative headquarters of Humla district and the starting and ending point of this trek.
It is a small hill town with terraced fields around it, and it also serves as a staging point for pilgrims flying in en route to Mount Kailash.
Because it holds the main airstrip serving the district and is also becoming connected to developing off-road routes, Simikot remains the main gateway for people, supplies, and logistics entering remote Humla.
Yalbang and the Namkha Khyung Dzong Monastery
Yalbang is one of the more developed villages along the trail, largely because of the Namkha Khyung Dzong Monastery, the largest monastery in Humla.
The monastery includes a small clinic that serves local people, and resident monks are often willing to show visitors around. Spending time here gives a useful early look at the Tibetan Buddhist culture that becomes more pronounced later in the trek, particularly in the Limi Valley.
Kermi and Its Hot Springs
Kermi is one of the older settlements on this route and one of the few places you pass through twice, once heading toward Hilsa and again on the return from Shinjungma.
Its natural hot springs are a genuine highlight after several long trekking days, and the village is also home to two old monasteries, Laikyo Gompa and Lhundrup Choeling Gompa, both worth a short visit if time allows!
Tumkot
Tumkot sits higher up the valley, where the landscape starts to turn drier and rockier.
The village holds the Dhungkar Choezom Monastery, one of the few Sakya monasteries in this part of Humla, reflecting a slightly different strand of Tibetan Buddhism than the Drikung Kagyu tradition found later in Halji.
The Nara La
The Nara La, at around 4,620 m, is the first of the trek's two major passes and marks the transition from the Humla valley into the high, dry country leading to the Tibetan border.
The climb is long, but the pass opens onto wide views of the Tibetan plateau, and on a clear day you can see prayer flags marking the top. Crossing the Nara La is one of the physically demanding sections of the whole route.
Hilsa and the Border Landscape
Hilsa sits directly on the Karnali River, facing a Chinese checkpoint on the far bank.
As the last Nepali village before the border, it has a different feel from the rest of Humla, shaped by cross-border trade and its role as a stop for Kailash pilgrims.
The dry, canyon-like landscape beyond Hilsa, on the way to Manepeme, is some of the starkest scenery on the entire trek.
Hilsa is also an important access point for pilgrims travelling toward Mount Kailash and Lake Manasarovar in Tibet. For travellers with limited time, helicopter services can shorten the journey considerably, while the Hilsa route can also serve as an exit point toward Nepal when pilgrims need to leave the Tibetan side because of altitude sickness or other problems.
Manepeme
Manepeme is a remote stop on the approach to the Limi Valley, set in dry, desert-like canyon country along the Karnali.
Few people live in this stretch of the trail, and the landscape of bare rock and layered cliffs is a clear signal that you are entering one of the more isolated parts of the route!
Til Village
Til is the smallest of the three Limi villages and the closest to the Tibet border.
Its stone houses and quiet, unhurried pace give a first real sense of the Tibetan Buddhist culture that defines the Limi Valley, after several days of harder trekking to reach it.
Halji and the Rinchenling Monastery
Halji is the largest of the Limi villages, and its Rinchenling Monastery is one of the oldest Tibetan Buddhist monasteries in Nepal, dating back close to 1,000 years to the era of the translator Rinchen Zangpo.
The monastery remains an active center of religious life for the village, and it is widely regarded as one of the most culturally significant sites in this part of the Himalayas. Spending time here is one of the clearest reasons to make this trek.
Jang
Jang is the last of the three Limi villages and keeps the same strong Tibetan character as Til and Halji, with its own small monastery and traditional stone houses.
It also sits close to the Chagzur hot spring, offering one more chance to rest before the trail climbs out of the valley toward Talung.
Talung
Talung marks the point where the trek leaves the Limi Valley behind and climbs into high, open pastureland along the Takchhe Khola.
The terrain here is more exposed and rugged than the valley villages, and it sets up the demanding crossing of the Nyalu La the following day.
The Nyalu La
At around 4,940 to 4,950 m, the Nyalu La is the highest point of the entire trek.
The climb from Talung is steep and demanding, but the pass rewards you with sweeping views across the Humla Himalayas. Crossing the Nyalu La is the physical high point of the trip and marks the start of the long return journey toward Simikot.
Shinjungma and the Return Valley
Shinjungma sits below the Nyalu La, along the Sali River, and marks the start of the long descent back toward Kermi and Simikot.
The surrounding valley is quiet and remote, with forested slopes replacing the high, bare ground of the pass. After the intensity of the Nara La and Nyalu La crossings, this stretch offers a more relaxed few days of walking back through familiar ground.
The Camping Experience
Because so much of this route has no permanent lodging, camping is part of what makes the trek possible at all!
Each evening, our crew sets up tents at a chosen camp spot, often near a river or village, and prepares a hot meal while you rest after the day's walk.
Camping here means truly remote nights, often with no other travelers nearby and very little light pollution, giving clear views of the night sky across much of the route.
