The Upper Mustang permit rules create confusion for one simple reason: most online information mixes Lower Mustang travel with Upper Mustang regulations.
You can reach Jomsom and Muktinath without special permits. But once you cross the Kagbeni checkpoint, the rules change completely.
I’ve guided this route repeatedly over the years, and the pattern is always the same. Trekkers don’t struggle because the permits are complicated. They struggle because different websites say different things.
Upper Mustang is a restricted region. It requires a Restricted Area Permit, an ACAP permit, a licensed guide, and a minimum of two trekkers. Solo trekking beyond Kagbeni is not allowed.
Once you separate Lower Mustang access from Upper Mustang regulation, the confusion disappears. This guide explains exactly what applies in 2026, what doesn’t, and what you actually need before crossing Kagbeni.
If you are still deciding whether this route fits your experience level or timeline, start with this definitive guide to Upper Mustang trek. To understand how permits connect to the actual walking days and route structure.

Before going deeper into permit details, it helps to understand how restricted areas differ from standard trekking routes in Nepal. The broader overview of trekking permits in Nepal explains how Mustang fits into the national permit system.
Where Upper Mustang Actually Starts
Upper Mustang doesn’t begin from Jomsom or Muktinath.
Those places are part of Lower Mustang. You can travel there freely with a standard Annapurna permit, and that’s exactly why the confusion starts.
Upper Mustang officially begins at the Kagbeni checkpoint.
Kagbeni is the checkpoint where the restricted region officially starts. Once you cross beyond Kagbeni toward Chele and Lo Manthang, you are entering a restricted region that requires a government-issued Restricted Area Permit and a licensed guide registered under that permit.
Reaching Jomsom or Muktinath without additional paperwork often creates the impression that Mustang is fully open. It isn’t. You are still in the unrestricted section.
If you attempt to continue north of Kagbeni without a valid Restricted Area Permit and a licensed guide, you won’t be allowed to proceed further. Permits aren’t issued at the trail. Beyond Kagbeni, the regulations of Upper Mustang apply immediately.
Why Upper Mustang Is a Restricted Area
Upper Mustang is classified as a restricted region by the Government of Nepal for three specific reasons.
Cultural preservation.
The region maintains intact Tibetan Buddhist traditions, monasteries, cave settlements, and social systems that have changed very little over time. Controlled access prevents rapid tourism development from reshaping that cultural fabric.
Managed tourism pressure.
Unlike Everest or Annapurna’s main corridors, Upper Mustang is not open-flow trekking. Entry limits help reduce infrastructure expansion, waste accumulation, and commercial overbuild in fragile high-altitude terrain.
Border sensitivity.
Upper Mustang lies near the Nepal–Tibet (China) border. Restricted status allows regulated movement and official oversight in a geopolitically sensitive zone. Access is simply controlled through permits and registered guides.
The permit system can feel restrictive at first. On the trail, it becomes clear that controlled access is what keeps Upper Mustang quiet and culturally intact.
Restricted routes operate very differently from mainstream treks such as Everest Base Camp, where infrastructure allows more flexibility. Understanding elevation patterns on routes like the Everest Base Camp elevation helps clarify why Mustang regulations exist.
Permits Required for Upper Mustang Trek
Upper Mustang requires two permits. Every trek I run in the region is processed under the same framework, with the structure remaining the same.
There are no hidden add-ons or seasonal pricing variations.
Restricted Area Permit (RAP)
The Restricted Area Permit is the primary document that allows entry beyond Kagbeni into Upper Mustang.
The cost is USD 500 per person for the first 10 days.
If your itinerary extends beyond 10 days inside the restricted zone, an additional USD 50 per person per day applies.
The permit is processed through Nepal’s Department of Immigration, which officially regulates restricted trekking permits in Nepal (see official trekking permit guidelines).
The permit is date-specific. Entry and exit dates are declared in advance, and the permit is valid only for that approved window.
It cannot be issued to a single foreign national and must be processed through a registered trekking agency in Nepal.
Annapurna Conservation Area Permit (ACAP)
Upper Mustang lies within the Annapurna Conservation Area, which means the Annapurna Conservation Area (ACAP) permit is still required in addition to the Restricted Area Permit. https://ntnc.org.np/project/annapurna-conservation-area-project-acap
The cost is NPR 3,000 per foreign national.
ACAP covers environmental management and conservation across the Annapurna region, including the Lower Mustang access corridor used to reach Kagbeni.
A TIMS card is not required for Upper Mustang.
Because this is a restricted region operating under the RAP system, TIMS does not apply.
Do You Need a Guide in Upper Mustang? (2026 Rule)
Solo trekking beyond Kagbeni is not allowed.
To enter beyond Kagbeni, you must be accompanied by a licensed Nepali guide whose registration is formally attached to your Restricted Area Permit.
When permits are checked at Kagbeni, officials verify the RAP document, the guide’s license number, and the group details before allowing entry. I’ve stood at that checkpoint many times, and the documentation is carefully reviewed before anyone is cleared to continue north.
Kagbeni is the primary control point, but inspections can also occur deeper inside Upper Mustang. Authorities have the right to verify permits anywhere within the restricted zone.
The guide is not optional. The guide is registered under the permit itself and is legally responsible for compliance and movement tracking throughout the trek.
Minimum Two Trekkers Rule Explained
The Restricted Area Permit for Upper Mustang is not issued to a single foreign passport holder. The government requires a minimum of two foreign trekkers listed under the permit structure. Authorities will not process a RAP for a single individual, regardless of payment.
If you are traveling solo, this does not prevent you from trekking. During permit processing in Kathmandu, agencies submit applications in compliance with the two-person requirement so that documentation meets government rules before it ever reaches Kagbeni.
Once the permit is issued properly, your paperwork is fully compliant and verified at checkpoints.
Can You Get the Permit Yourself?
No, the Upper Mustang Restricted Area Permit cannot be obtained independently by a foreign traveler.
The permit is processed through Nepal’s Department of Immigration, and applications must be submitted by a registered trekking agency. The system is structured this way for administrative control, movement tracking inside the restricted region, and coordinated documentation management.
Permits are issued with guide details attached and logged against fixed entry dates. This requires agency submission, official registration numbers, and verification before approval.
You cannot obtain the permit at a checkpoint, at Kagbeni, or by applying individually after arriving in Mustang. Processing is completed in Kathmandu before the trek begins.
How Permit Checking Works on the Trail (Authority Section)
At Kagbeni, your guide presents the original Restricted Area Permit, passport copies, and the ACAP permit. Officials review the permit number, verify the validity dates, confirm the approved number of days, and verify the guide’s license details against the document.
I’ve stood at that checkpoint many times, and the review is deliberate. They don’t wave groups through casually.
Your guide carries the original paperwork throughout the trek. Copies are not sufficient. If the dates don’t match or the documentation is incomplete, the entry is denied at the checkpoint.
Kagbeni is the main control point, but verification does not end there. Officials have the authority to conduct deeper inspections of permits within Mustang. This is why documentation must remain consistent from the first day to the last.
Once you pass Kagbeni, you are moving under a monitored permit system, not open-access trekking.
There is no option to fix paperwork later once you are on the trail. Documentation must be correct before you leave Kagbeni.
Documents Required for Upper Mustang Permit
The paperwork itself is simple. What matters is accuracy. I’ve submitted these permits many times, and small inconsistencies in dates or passport details are what delay processing.
For a Restricted Area Permit, the following documents are required:
- A valid passport with at least six months of remaining validity
- A valid Nepal entry visa
- Passport-sized photographs
- Confirmed travel dates for the Mustang itinerary
The travel dates must match the exact number of days requested under the Restricted Area Permit. The government issues the permit strictly based on those dates, and extensions are not automatic once you are already on the trail.
When these documents are prepared correctly, the process moves smoothly.
How Long Does Permit Processing Takes
Permit processing typically takes one to two working days in Kathmandu. I submit the application after you arrive, once your passport and visa details are confirmed and travel dates are aligned.
Permits are issued centrally through the Department of Immigration, not at trail checkpoints. When documentation is accurate, and group details meet the two-person requirement, approval is routine.
By the time you leave Kathmandu, your permits are already in place. You don’t deal with offices, queues, or last-minute surprises on the trail.
Common Mistakes Trekkers Make
Most permit issues I deal with aren’t caused by complicated rules. They happen because expectations were formed from mixed or outdated information before arrival.
Confusing Lower Mustang with Upper Mustang
You can travel to Jomsom and Muktinath without a Restricted Area Permit. That creates a false sense that the entire Mustang region is open. It isn’t. The requirement begins immediately after Kagbeni. I’ve had conversations at Kagbeni with travellers who assumed they could just continue north because they had already reached Muktinath without issue. That’s where the misunderstanding becomes expensive.
Relying on outdated solo trekking information
There is still old content online suggesting you can arrange the permit alone or “figure it out” on arrival. Current regulations require a licensed guide and at least 2 foreign passport holders under the permit structure. That rule is enforced at the application stage, not negotiated on the trail.
Miscalculating permit duration
The Restricted Area Permit is issued for fixed dates. If your itinerary exceeds the approved period, you cannot simply extend it from Lo Manthang. Dates must be correct before submission. Once the permit is printed, it reflects those exact travel days.
Assuming permits are available at the checkpoint
Permits are not issued at Kagbeni. They are processed in Kathmandu through registered agencies and cleared before you start the trek. If you arrive at the checkpoint without proper documentation, you will not be allowed to continue north. There is no on-the-spot workaround.
The rules themselves are not complicated. The confusion comes from mixing Lower Mustang access, outdated online advice, and assumptions about flexibility. When permits are structured correctly before departure from Kathmandu, the process is straightforward.
Planning Upper Mustang After Permits
Once the permits are clear, the only real question left is whether Upper Mustang is the right trek for you.
The regulations don’t make the route difficult. They simply structure access. What matters now is whether a dry trans-Himalayan landscape, long open valleys, walled villages like Lo Manthang, and a culturally preserved Tibetan-influenced region match how you want to experience Nepal.
If that aligns with how you want to spend your time on the trail, review the Upper Mustang trek itinerary and look at the route in practical terms, daily walking hours, altitude pattern, and timing.
If permits were your main hesitation, you now know the rules are predictable. The remaining question is whether Upper Mustang’s pace and landscape match what you want from a trek.
