Upper Mustang, often called the Forbidden Kingdom, sits in the far northern corner of Nepal, tucked beyond the Annapurna and Dhaulagiri mountain ranges. Getting there is not complicated, but it does require proper planning, the right permits, and a clear understanding of the available routes. Most travelers fly from Pokhara to Jomsom and then trek or drive north to reach the restricted zone of Upper Mustang.
Upper Mustang lies in the Mustang District of Gandaki Province, in the northern part of Nepal, sharing a border with the Tibet Autonomous Region of China. It sits in the rain shadow of the Himalayas, which means it stays dry even during Nepal’s monsoon season. The region covers an area of roughly 2,178 square kilometers and sits at an average elevation between 3,000 meters and 4,000 meters above sea level.
Geographically, Upper Mustang, Nepal, forms the upper portion of the Kali Gandaki River valley. The landscape here is strikingly different from the rest of Nepal. Instead of green hills and dense forests, you find red and ochre cliffs, eroded canyon walls, high-altitude desert plains, and ancient cave settlements carved into hillsides. The region borders the Dolpa District to the west and Lower Mustang to the south.
Because of its remote location and proximity to Tibet, the Forbidden Kingdom remained closed to all foreigners until 1992. Even today, access is tightly controlled through a special Restricted Area Permit. This controlled access is exactly what has preserved Upper Mustang’s unique Tibetan culture, ancient monasteries, and traditional way of life, making a trek in Nepal to this region feel like stepping into another century.
To reach Upper Mustang, the standard route is: fly from Kathmandu to Pokhara, then take a short mountain flight from Pokhara to Jomsom, and finally trek or drive north from Jomsom through Kagbeni into the restricted Upper Mustang zone. There is no direct road or flight to Lo-Manthang, the walled capital of Upper Mustang, which is why either trekking or a jeep journey from Jomsom remains the primary method of access.
The first leg of the journey takes you from Kathmandu to Pokhara, which is the main gateway city for Upper Mustang, Nepal.
You can reach Pokhara in two ways:
From Pokhara, the most common and practical way to reach Jomsom is by a short mountain flight. The Pokhara to Jomsom flight is one of Nepal’s most thrilling domestic routes, lasting just 20 to 25 minutes. During this flight, you get close aerial views of Annapurna I, Dhaulagiri, Nilgiri, and Tukuche Peak.
Jomsom sits at an altitude of 2,713 meters and serves as the headquarters of Mustang District. Once you land, the journey into Upper Mustang truly begins. Flights are operated by airlines such as Tara Air and Summit Air, and they run early in the morning since afternoon winds in the Kali Gandaki valley make flying difficult.
It is worth noting that flights from Pokhara to Jomsom are frequently weather-dependent. Delays are common, especially during winter and the early monsoon period. Therefore, building buffer days into your Upper Mustang trekking itinerary is strongly recommended.
After landing in Jomsom, the trek into Upper Mustang begins with a walk north toward Kagbeni. This stretch takes approximately 3 hours on foot and follows the wide, windswept Kali Gandaki valley. Kagbeni is the last major settlement before the officially restricted zone of Upper Mustang begins.
Alternatively, a jeep can cover the Jomsom to Kagbeni stretch in about 45 minutes, but most trekkers choose to walk to begin the experience on foot.
Beyond Kagbeni, you officially enter the restricted zone of Upper Mustang. This section is only accessible with a valid Restricted Area Permit issued by the Nepal government. The Upper Mustang Jeep Tour is an increasingly popular option for those who prefer to cover more ground without trekking every day. A jeep from Kagbeni to Lo-Manthang takes approximately 1 to 2 days depending on road conditions, while trekking the same route takes 4 to 5 days.
The Upper Mustang Trek route from Kagbeni to Lo-Manthang passes through:
Each of these villages offers a unique window into the Loba community’s way of life, ancient monasteries, and the dramatic trans-Himalayan landscape.
The Upper Mustang Trek is rated as moderate in difficulty and does not require any technical climbing skills. Most healthy adults with a basic level of fitness can complete it with proper preparation. The daily walking hours range between 5 and 8 hours, and the highest point on the standard itinerary reaches around 4,230 meters near Gyu-La Pass.
However, “moderate” does not mean easy. The trail presents its own set of challenges that trekkers should prepare for:
Compared to treks like the Everest Base Camp Trek or the Annapurna Circuit, the Upper Mustang trek in Nepal sits at a lower altitude range, which reduces the risk of severe altitude sickness. Nevertheless, gradual acclimatization, proper hydration, and slow pacing are essential. Trekkers with prior hill-walking experience will find the journey more comfortable, though well-designed itineraries from operators like Trexmount Ventures build in appropriate rest days to help everyone adjust.
The hardest trek in Nepal is generally considered to be either the Dhaulagiri Circuit Trek or the Kanchenjunga Base Camp Trek, both of which involve extreme altitude, technical passes above 5,000 meters, and very remote terrain with limited rescue options. The Upper Mustang trek Nepal, while challenging in its own right, is not classified among Nepal’s hardest treks.
What makes a trek hard in Nepal is usually a combination of altitude, technical difficulty, remoteness, and physical demand. The Dhaulagiri Circuit, for example, crosses passes above 5,200 meters and involves glacier travel. The Kanchenjunga region sits in the far east of Nepal and requires a multi-week commitment with almost no infrastructure along large sections of the trail.
The Upper Mustang trekking experience stands apart because its challenges are more environmental than physical. The isolation, cultural unfamiliarity, basic accommodation, and long days in a desert landscape are what test trekkers most. For many people, that combination makes it mentally one of the most demanding journeys they have ever undertaken, even if it does not rank among the technically hardest treks in Nepal.
No, Nepali citizens do not need the Restricted Area Permit that foreign trekkers are required to hold. However, they must still carry valid identity documents and respect all local regulations within the Upper Mustang area. The Restricted Area Permit system applies specifically to foreign nationals visiting the region.
For foreign trekkers, the permit structure for the Upper Mustang Trek Nepal is as follows:
It is also worth noting that a minimum group size of two trekkers is required to obtain the Restricted Area Permit. Solo foreign trekkers must join a group or arrange for a partner through their trekking agency. Additionally, the permit must be accompanied by a licensed trekking guide at all times inside Upper Mustang.
No, Muktinath is not technically in Upper Mustang. It falls within Lower Mustang, near the town of Ranipauwa at an altitude of approximately 3,800 meters. However, Muktinath is a significant spiritual stop on the Upper Mustang Trek Nepal itinerary and is often visited on the return journey.
Muktinath Temple is sacred to both Hindus and Buddhists. For Hindus, it is one of the 108 Divya Desams, or sacred Vishnu temples, mentioned in ancient scriptures. For Buddhists, it is associated with Guru Rinpoche and represents a Dakini power place. The temple complex features:
The Trexmount Ventures Upper Mustang trek itinerary includes a dedicated day at Muktinath on Day 15, where trekkers ascend from the Chusang area to this sacred site and have time to explore and participate in the temple rituals before continuing down toward Jomsom.
Trexmount Ventures offers the Upper Mustang Trek Nepal at a starting cost of USD 2,440 per person, covering a 20-day itinerary from Kathmandu to Kathmandu. This package includes all necessary permits, domestic flights, accommodation, guide fees, and meals as specified in the itinerary.
The 20-day Upper Mustang trekking journey follows this broad structure:
The Upper Mustang Jeep Tour option is also available for those who prefer covering certain legs by vehicle. Jeep tours typically run between Jomsom and Lo-Manthang with stops at key cultural sites, making the journey accessible even for those with limited trekking experience.
Reaching Lo-Manthang, the heart of Upper Mustang, from Kathmandu typically takes around 8 days on a standard trekking itinerary. The first 2 days cover Kathmandu preparation and the drive to Pokhara. Day 4 involves the flight to Jomsom and trekking to Kagbeni. From Kagbeni, it takes roughly 4 more trekking days to reach Lo-Manthang through Chele, Geling, and Tsarang. With the Upper Mustang Jeep Tour option, you can cut the Jomsom to Lo-Manthang portion down to 1 to 2 days.
No, foreign trekkers cannot legally enter Upper Mustang without a licensed guide. The Restricted Area Permit specifically requires that trekkers be accompanied by a registered guide from a licensed trekking agency at all times. This rule applies within the entire restricted zone beyond Kagbeni. Trexmount Ventures provides experienced and licensed guides for all Upper Mustang treks, ensuring both legal compliance and safety throughout the journey.
Upper Mustang can be visited almost year-round because it lies in a rain shadow zone. However, the best times are spring (March to May) and autumn (September to November) for clear skies and comfortable temperatures. The monsoon months from June to August are also excellent because the region stays dry while other parts of Nepal receive heavy rain. Winter months from December to February are cold but possible with proper preparation.
It depends entirely on what you want from the experience. The Upper Mustang Jeep Tour is faster and physically easier, making it ideal for older travelers, families, or those with limited time. Trekking, on the other hand, allows you to absorb the landscape more deeply, visit remote cave sites, and fully immerse yourself in the cultural environment at a natural pace. Many trekkers choose a combined option: trekking on the way in and jeeping on the way out, or vice versa.
To obtain the Restricted Area Permit for Upper Mustang, you need a valid passport, two recent passport-sized photographs, a copy of your travel insurance, and confirmation of trekking through a registered agency like Trexmount Ventures. The permit cannot be obtained independently by individual trekkers. Your trekking agency handles the full application process on your behalf, which is one of the key reasons working with a reliable operator matters significantly.
Mobile network coverage in Upper Mustang Nepal is limited but improving. NTC (Nepal Telecom) provides some coverage in major villages like Lo-Manthang, Ghami, and Tsarang. However, connectivity can be unreliable in remote sections of the trail, especially between Tange and Chusang. WiFi is available in some teahouses in Lo-Manthang at an additional cost, but speeds are slow. It is best to set realistic expectations about staying connected during an Upper Mustang trek.
Lo-Manthang is the ancient walled capital of the Kingdom of Lo, which is the historical heart of Upper Mustang Nepal. Founded in 1380 CE, the city is surrounded by high mud-brick walls and contains four major monasteries, a royal palace, and a community of around 1,000 Loba residents. It is one of the few remaining medieval Himalayan walled cities still inhabited by people following ancient Tibetan Buddhist traditions. Reaching Lo-Manthang is the primary goal of the Upper Mustang Trek Nepal.
Yes, combining the Upper Mustang trek Nepal with the Annapurna Circuit is a popular option for trekkers who have three to four weeks. The Annapurna Circuit naturally passes through Jomsom and Muktinath, both of which are key points on the Upper Mustang trekking route. You can enter Upper Mustang from Kagbeni after completing part of the Annapurna Circuit, or combine it as a separate extension before or after. Trexmount Ventures can customize an itinerary that connects both routes efficiently.
Accommodation on the Upper Mustang trek consists mainly of locally run teahouses and small guesthouses. Rooms are simple, usually twin-sharing, with basic bedding and limited heating. Attached bathrooms are rare in more remote sections but are available in larger villages like Lo-Manthang and Kagbeni. While the facilities are basic by international standards, the warmth of Loba hospitality and the authenticity of the experience more than compensate for limited amenities.
The Restricted Area Permit for Upper Mustang costs USD 500 per person for the first 10 days and USD 50 per day for every additional day. This cost applies to all foreign nationals regardless of nationality. On top of this, trekkers also need to pay for the ACAP permit at approximately USD 25 and the TIMS card at approximately USD 25. The total permit cost alone can reach USD 540 or more, depending on the length of your stay inside the restricted zone.
