Now let’s talk about the official paperwork needed for this adventure, how it can be issued and how much they cost.
Restricted Area Permit
This is the most important one for this trip, basically the most valuable paper for everything north of Kagbeni. If you don’t get this, then the trip is basically impossible.
It costs around $50 per person per day.
The policies have changed as of 2026; they used to be a flat $500 for 10 days, even if you were only there for 5 days. As of now, you can only pay the cost of the days you’re inside the restricted zone, and there’s no need for other days.
But still you need a licensed certified guide as trekking solo is restricted and the permit must be issued via a registered Nepali trekking agency mandatorily.
Annapurna Conservation Area Project (ACAP)
The Annapurna Conservation Area (ACAP) is needed for the Upper Mustang Trek because it sits inside the Annapurna Conservation Area. You’ll also need this along with RAP.
The cost ranges between $23-$25, which is around NPR 3,000, and it is valid for the entire duration of your trip until you leave the ACAP area.
TIMS card (Trekkers’ Information Management System)
The TIMS permit is a safety tracking permit in Nepal, typically costing around $15, approximately, which is valued at NPR 2000 Nepali. This permit can be booked via an agency, but as of 2026, this too can be mostly issued as e-TIMS with a QR code for easy scanning at the checkpoint to avoid the hassle of paper at Jomsom and Kagbeni.
The Solo Permit (March 2026)
One of the biggest changes and update in regards to the permit and paperwork was the group structure requirement criteria for anyone to get a permit in order to trek to the region.
For instance, if you wanted to travel to these regions that are labelled as restricted zones by the government, then you were supposed to get a permit (RAP) for two people on paper, even if you were only one travelling, as the guide was not considered your travel partner on paper, even if the company of a guide was mandatory.
But as of now, you can travel with a permit for yourselves only, but you still need a government-certified guide, and you’re not allowed to wander alone due to border restrictions and safety purposes for yourself.
But the good thing is, you no longer need a partner on paper for permit issuance.
Season and Weather
Since we have talked about the permits, let’s talk about weather and time regarding when it is best to visit.
Weather and seasons are not much of trouble while visiting Upper Mustang as majority the trekking that is usually affected is due to rainfall and slippery trils afterwards but as for the Upper Mustang since the region is a rain-shadow region it remains highly dry and unaffected from the rainfall keeping the trails dry and itact wven during the monsoon/offseason.
The only concern in this reion for trekking is the dusty storm and chilling wind that is to be kept into consideration.
Since June to August is a major monsoon period in Nepal and major trails receive the precipitation and the trail halt but as for the Upper Mustang you don’t need to worry as it remains highly unaffected and as a result not even a single day of your trip goes wasted.
High-altitude insurance and evacuation : A safety net
Previously, very long ago maybe insurance was a personal choice but as of now in 2026, it’s a mandatory requiemrnet. You don’t a acquire insurance, you don’t get to travel to the region.
And the reason for making the insrcance mandatory is much more of a concern of safety and security of travellers rather than just a legal fees and formality for insurance company.
Below are some of the details regarding the necessity for insurance and heli-rescue and why it’s required.
Search and rescue : The region is a high-altitude arid zone and forbidden one due to the proximity to the tibetan boarder and beside thar it is one of the highest region on earth surrounded by tall mountains from overall and dry climate it’s highly risky for outsiders to get lost in the vicinity and to make the matter worse it’s more difficult to get rescued via phone calls and messages as the topography doesn’t support network stability and in such case the only option to be saved is through a heli-search rescue operation as it helps find the lost travellers from high view from above.
In high-altitude regions, search operations alone are not enough. In case of a medical emergency, the only way to receive proper medical assistance is often through helicopter evacuation, as regular medical services are not available at such elevations.
When purchasing insurance, you should also carefully check the policy details. Make sure it includes coverage for rescues above 5,000 meters, as many standard evacuation insurance policies only cover up to 3,000 meters.
The 5,000m clause : Generally speaking, the standard travel insurance only covers the rescue operation around the elevation of 3000 meters. But since the upper Mustang goes beyond 3,800m at minimum just in Lo Mantang and much more beyond it as the elevation rises The general standard rescue doesn’t cover it, which is why you have to take the insurance policy that covers a 5000 meter rescue.
Heli-Evacuation, search and Rescue.
Speaking of the nearest medical facility in the region, it is either Kathmandu or Pokhara as you won’t find any medical services in such high-altitude regions and it might be very costly which is why it is recommended for you to be pre equipped with the insurance policy either from your native nation or while in capital because in emergency helicopter evacuation without an insurance might cost from $3000 to $6000 atleast and if you have good insurance policy than it might help you manage the cost.
Emergency contact: While you do your paper works for the insurance. You must provide the policy number and 24/7 emergency contact number to the insurance provider As they will cross-check this to ensure policy is active for duration of your permit in Nepal.
Accommodation and connectivity: The Teahouse Reality
Now, a most common misconception among the travelers are the restricted region is that they often think they will end up sleeping in tents or eating canned foods or packed lunches during the trip, which is far from reality.
Since this region is beyond the mountains, the clouds and rainfall do not affect the region even during the off seasons and monsoons, which is why the teahouses are usually open and you won’t have to worry about the lodging and fooding as you’ll get to have basic rooms, hot meals and attached bathroom in large.
The digital detox : Even with the shift e-TIMS QR codes, do not rely on your phone’s data. Upper Mustang is a “shadow zone” for many carriers.
Offline documents : Download your e-TIMS, your Nepal visa copy and your insurance policy to your phones local storage.
Wi-fi charge : Most of the houses charge of fee roughly in NPR 500 to 1000 for Wi-fi password. The high speed is often barely enough for Whatsapp text later than uploading drone footage or high resolution photos.
Charging : Electricity is largely solar powered in smaller villages. Be prepared to pay fee of 200 to 500 NPR to charge your power banks or camera batteries.
The “No solo trekking” Rule : why a guide is non negotiable.
While the 2026 rulel allows fora solo permit (meaning you don’t need a second traveler), the requirements for Govt. certified guide remains as well. This isn’t just a bureaucratic order, this guide is essential for several reasons.
The Cultural Bridge : Upper Mustang is the heart of Loba culture. Many of the interesting sites like this Sky Caves or private sections of Jamapa Lakhang requires local permission. Your guide acts as intermediary ensuring your respect local customs. Like walking clockwise around chortens and handling the monastery entrance fees which are separate from your RAP.
Navigation in the Dust Bowl : Different from the lush trails of the Annaourna Circuit, the path in the Upper Mustang can be obliterated by the fierce afternoon wins in the high altitude desert, losing the trail for even an hour can lead to several dehydration.
Checkpoint management : There are major checkpoints in Jomsom and Kagbeni. Your Guide manages the “Logbook” entries. Without a guide to sign you in and out, you are technically in the region illegally, which can result in immediate deportation and heavy fines for both you and your agency.
Health monitoring : High Altitude Pulmonary Edema (HAPE) can hit even for the fittest trekkers. The certified guide is trained personnel assigned to spot the signs of altitude sickness and will make the call for a descent before it becomes a life- threatening emergency for anyone.
Photography & Drones: Permits, Risk and Regulations
The region has become more sensitive as the Korala Border (China/Tibet border) in late 2025/early 2026 has been opened and is more sensitive in terms of traffic flow and security, due to which certain restrictions have been imposed for security reasons.
For instance:
Photography restrictions:
While the ancient walled city of Lo Manthang is the goal for most travellers, many now push further north to the Korala border
The rule
You are generally free to photograph the landscape and culture, but snaps of military personnel, checkpoints and the border barriers itself is strictly forbidden.
The risk
Performing photography acts in the border regions is always risky, as it is a very sensitive region.
Doing such activities in these regions without specific permits easily arouses suspicions of acts like spying and information supplying, and many more, which might get people in trouble with the act of immediate questioning, deletion of their files or even your resource being seized and held for questioning and investigation.
So let’s keep this point in mind, that is, to ask a guide before pulling out your zoom lenses or cameras anywhere near the border. If you see a uniform or a bunker, keep the lens caps on or the camera inside your bag. Before taking any snaps, ask your guide, know the regulations and then only take the pictures after they approve.
The drone Dilemma (2026 rules)
Another element of border intolerance is the Drone Act, as Nepal has now instated zero tolerance for unregistered drones in the vicinity, as it signals a hovering indication of spying and breach of security, just as mentioned before. This is why even a mini drone like the DJI Mini 4 Pro, which is exempt from rules in the US or Europe, must be registered in Nepal.
The 3-permit Gauntlet.
To fly legally in the Upper Mustang, you need more than just one paper. You’ll need:
- CAAN Registration : A unique identification number (UIN) from the Civil Aviation Authority Nepal.
- Home Ministry clearance : Because you are in a restricted area near an international border.
- ACAP Drone Permit : An extra fee is to be paid to the Annapurna Conservation Area project.
- The border no-fly zone : Even if you have all three permits, there’s a 5km no-fly buffer zone from the Chinese border.
If your drone’s GPS logs show you flying near the Korola fence. It is considered a national security breach.
The cost is expected to be between $300 to $800 in total peace and agency service charges to get these permits.
Cultural sensitivity in monasteries and sky caves.
Beyond the legal rules, there are unwritten ones. Upper Mustang is the Living museum of Tibetan Buddhism.
Sky caves:
These are ancient burial and meditation sites. Flying a drone near them is often considered a “Spiritual disturbance” by the local villagers. So it is necessary to respect the culture of the local people and try not to breach it.
Inside monasteries
Photography inside the Gumba (Monasteries) is universally banned to protect the ancient pigments in the murals from flash damage and respect for the sacred space.
Logistics: The ‘‘Original Passport rule’’
Something travellers need to pin as a notice is:
Presence in Kathmandu: Your agency usually needs an original passport for a couple of business days in Kathmandu to finalise the RAP, as it’s quite a hassle to get it in Pokhara or at the Kagbeni checkpoint. Travellers need to know they should budget 2 days in the city before flying to Jomsom.
Cost clarification: ACAP fee revision
Do your cost workouts on ACAP. While it was $20 for many years, 2026 resources are now reporting a revised fee of $30 (NPR 4000) for foreign nationals to account for inflation and conservation efforts. It’s worth adding a confirmation with your agency note here.
The Buffer Day advice.
Since the permit is now per day, the strategy for travellers has changed.
The strategy : Travellers are suggested. You calculate your days carefully. If they get a 7-day RAP but get stuck behind a landslide or flight delay for one day, they will face heavy fines at the Kagbeni exit checkpoint. Suggesting a one-day buffer in the permit application is a pro tip that saves people money in the long run.
| Permits type | Foreign Nationals | SAARC Nationals | Validity/Notes |
| Restricted area permit (RAP). | $50 per persona per day. | $50 per person. | Only covers days north of Kagbeni. No flat 10-Day fee required anymore. |
| ACAP Permit | NPR 3,000 (∽$23) | NPR 1,000(∽$8) | Valid for the entire duration of the Trek until you exit the ACAP area. |
| E-TIMS | NPR 2,000 (∽$15) | NPR 1,000 (∽$8) | Now issued as a digital QR code for faster checkpoint scanning. |
So how do you apply?
Your trekking agency in here handles the backend if you provide the following credentials:
- A scanned copy of a passport with at least 6 months’ validity.
- Copy of your Nepal visa.
- Two PP-sized photos (digital/ physical)
- Insurance proof (explicit mention of high-altitude heli-evacation)
