The name Mustang has a certain ring to it, conjuring images of a remote mountain land steeped in centuries-old complex culture. A Tibetan enclave in Nepalese territory, this ancient kingdom was long inaccessible to foreigners, visited only by a handful of pioneering explorers such as Guiseppe Tucci and Michel Peissel. While a trek to this fabled "forbidden kingdom" became possible for a limited number of travelers in 1992, the region's mystique remains, offering an experience entirely different from the more frequented Annapurna and Everest trails.
This 18-day Upper Mustang Trek is a challenging yet highly rewarding journey for those who have already experienced the wonders of Nepal and now seek a deeper, more profound adventure. You will follow the ancient salt-trade routes that were once part of the Silk Road, which offer a vivid lesson in the resilience and unique culture of the Loba people. Bordering Tibet, the trek explores regions that have preserved authentic Tibetan culture and tradition, with Lo Manthang, the capital, as the culmination of this exceptional journey.
As you traverse one of the driest regions of Nepal, you'll be rewarded with a landscape of red cliffs, canyons, and fairy chimneys that contrast dramatically with the high peaks of the roof of the world. For those who have already experienced the wonders of Nepal and now seek a journey into a world of ancient culture, profound history, and raw natural beauty, the Upper Mustang Trek is the ultimate adventure. It is an experience that will not only challenge you physically but will enrich you culturally and spiritually.

Kathmandu to KathmanduExpand all
Depending on how you plan to arrive at Kathmandu, we will arrange for you to rendezvous at your hotel in Thamel. In most cases, you will arrive at Kathmandu via Tribhuvan International Airport where you will meet your guide.
In the evening, you will join for a program briefing with your group members. In case you arrive late at night, you will meet your group members next day at breakfast during which you will also be briefed about your program.
You have the choice of a scenic 30-minute flight or a picturesque 5-6 hour drive from Kathmandu to the beautiful lakeside city of Pokhara. The flight offers magnificent mountain views, while the drive provides a fascinating glimpse into Nepal’s diverse landscapes. After settling into your hotel, you are free to explore the tranquil Lakeside area.
The day begins with a thrilling 20-minute mountain flight from Pokhara to Jomsom, the administrative center of the Mustang region. From Jomsom (2,743 m), your trek begins, following the windswept Kali Gandaki riverbed to the medieval village of Kagbeni. Known for its ancient chortens and a historic fort, Kagbeni is the official gateway to Upper Mustang. Here, a blend of Thakali and Loba cultures sets the stage for the journey into the heart of the forbidden kingdom.
Leaving Kagbeni, you officially enter the restricted area of Upper Mustang, following the classic route.
The trail ascends from the riverbed into a world of dramatic, arid landscapes. Today's trek involves navigating rocky paths and gradual climbs. You will witness the striking contrast between the green oases of the villages and the barren cliffs and canyons, a defining feature of the region's rain-shadow geography.
This is a long and challenging day with several ascents and descents over high passes. You will cross the Taklam La Pass (3,624 m) and Darjori La Pass (3,735 m), which provide stunning views of the surrounding peaks. En route, you will visit the sacred Chungsi Cave, a revered meditation site with a deep spiritual connection to Guru Rinpoche (Padmasambhava), the founder of Tibetan Buddhism. After a final ascent to the welcoming village of Syangmochen, you can reflect on the powerful legends etched into the very landscape.
Another long day of trekking on the classic route lies ahead.
Today's journey takes you to the heart of the kingdom. You will cross the high Nyi La Pass (4,010 m), the highest point of the main trail, which offers expansive views of the vast, arid plateaus. The trail then descends, leading you to the magnificent village of Tsarang. This village is home to a massive monastery and a crumbling five-story palace, which legend says was built using a human backbone as a pillar.
Finally, you arrive at the the walled capital of the former Kingdom of Lo Manthang.
The trail is relatively short, building a sense of anticipation for your arrival in Lo Manthang. After settling into your accommodation, the afternoon is dedicated to exploring the city's ancient mud walls, narrow alleyways, and its three main monasteries—Jampa Gompa, Thubchen Gompa, and Choede Gompa—which house some of the finest murals in the Himalayas.
This is a dedicated day of cultural immersion and exploration around Lo Manthang.
You'll hike to Chooser (3,857 m), a village known for its unique "sky caves." , where you will visit the ancient Shija Jhong Cave complex, believed to be the homes of ancient monks, as well as the revered Garphu and Niphu monasteries, which house ancient murals and relics. These sites are a testament to the region's deep and enduring spiritual history.
A challenging day of cultural exploration, today’s trek takes you to two of the region's most fascinating historical sites.
You will visit the Konchok Ling and Ritseling caves, ancient hermitages and homes carved into the dramatic rock faces, offering a glimpse into the isolated lives of early inhabitants and hermits. The journey offers unique geological and historical insights that are unparalleled anywhere else in the Himalayas.
The journey back begins, but the adventure is far from over as you get to explore the significant sites of interest on the western route of the Upper Mustang trek.
The long, demanding day of trekking that takes you to the village of Ghami. You will cross the high passes of Marang La (4,295 m) and Mui La (4,135 m), which offer some of the most spectacular views of the entire trek.
Along the way, you'll visit the ancient Ghar Gompa, one of the oldest monasteries in the world, believed to have been built by Guru Rinpoche in the 8th century. Legend says that a wish made here will be fulfilled. You'll also see the striking red cliffs of Dhakmar, where it is said Guru Rinpoche killed a demon, leaving the cliffs stained with its blood.
Another long and rewarding day of trekking. You'll rectrace your steps back to the picturesque village of Samar, a traditional trading post along the ancient salt route.
Today is a shorter, more relaxed day as you descend to Chhusang for some well-deserved rest. The village is known for its dramatic cliffs and unique geological formations.
The rest of the day is at your leisure. You can request an optional excursion to the small settlement of Tetang is you wish to continue exploring.
This is your last day in Upper Mustang as you retrace your steps back to Kagbeni.
From there, you will continue to the sacred pilgrimage site of Muktinath. Here, you can witness the peaceful coexistence of Hindu and Buddhist faiths, with its famous temples and 108 water spouts. It is a powerful cultural and spiritual highlight to end your trek.
Today, you'll begin your final long descent. Instead of following the motorable road to Jomsom, you'll detour you via the traditional village of Lupra, known for its Bon monastery, offering a final unique cultural encounter. The trail descends through the Kali Gandaki valley, eventually leading you back to the bustling town of Jomsom, where you can celebrate the completion of your trek.
You have the choice of a 20-minute flight or a scenic 7-8 hour drive back to Pokhara. The flight offers a final, sweeping view of the Himalayan ranges, while the drive provides a more in-depth experience of the beautiful landscape.
The morning is yours to relax by the lakeside in Pokhara, reflecting on the incredible journey. In the afternoon, you will take a short flight back to the capital, Kathmandu.
This is a free day in Kathmandu to unwind, explore the city, and shop for souvenirs. You can visit some of the UNESCO World Heritage Sites you may have missed or simply enjoy the vibrant atmosphere of the city.
In the evening, you're invited to a farewell dinner celebrating your trip in Nepal.
Depending upon your exit plans, with the most probable being your return flight back home, your guide or a representative will accompany you to the Tribhuvan International Airport.

Essential Information
The Rhythm of the Mountains: Best Seasons to Trek
- Spring (March-May) & Autumn (September-October): These are the classic Himalayan trekking seasons, offering stable weather, moderate temperatures, and clear skies for optimal mountain views.
- The Monsoon Advantage (June-August): Unique among Nepal's great treks, Upper Mustang lies in the Himalayan rain shadow. This makes it an excellent trekking destination during the monsoon months when other regions are inaccessible. This period also often coincides with major cultural events like the Tiji Festival (typically in May), a vibrant, multi-day Buddhist ritual in Lo Manthang.
Forging Your Strength: Physical Fitness and Preparation
- Endurance is Key: The primary physical requirement is exceptional cardiovascular endurance. The ability to walk for 6-9 hours daily, on consecutive days, with a daypack is essential. A training regimen focused on long-distance hiking, running, cycling, or stair-climbing for several months prior to departure is highly recommended.
- Mental Preparedness: The psychological demands of trekking in a remote, harsh environment should not be underestimated. The relentless wind, dust, and isolation can be as challenging as the physical exertion. Mental conditioning through visualization, breaking down long days into smaller, manageable goals, and maintaining a positive mindset are crucial for success.
Keys to the Kingdom: Permits and Fees
Trekking in Upper Mustang is a privilege, regulated by the Government of Nepal to preserve its unique culture and fragile ecosystem. The permit process is strict and non-negotiable.
- Mandatory Permits: All foreign trekkers require two permits:
- Mustang Restricted Area Permit (RAP): This is the primary permit, costing USD $500 per person for the first 10 days. Any additional days spent within the restricted zone (north of Kagbeni) cost an extra USD $50 per day.
- Group Requirement: A minimum of two trekkers is strictly required to obtain the RAP permit. Even if you plan on traveling solo, you will still need to hire two valid passports (with valid Nepali visas) to meet the mandatory group size for the permit application.
- Annapurna Conservation Area Permit (ACAP): As the trek begins and ends within the Annapurna Conservation Area, this permit is also required. The cost is USD $30 per person.
- The Process: Permits can only be obtained through a government-registered trekking agency in Nepal. Independent trekking is strictly forbidden. A minimum group size of two trekkers, accompanied by a licensed Nepali guide, is required to secure the permits.46 This regulation underscores the necessity of booking through an accredited operator.

Himalayan Hospitality: Accommodation, Food, and Water
- Accommodation: Lodging on the trek is in teahouses—simple, family-run guesthouses. Rooms are typically twin-bedded with basic furnishings. While clean and comfortable, trekkers should expect shared bathroom facilities and limited heating, which is usually confined to a stove in the main dining hall during the evenings. Extras such as charging electronic devices and hot showers are available for a small fee.
- Food: Teahouse menus offer a surprising variety of dishes, but the staple is Dal Bhat—a nutritious and energy-rich meal of rice, lentil soup, and vegetables, which often comes with free refills. It is advisable to stick to vegetarian options at higher altitudes, as meat is not always fresh.
- Water: Tap water is not safe to drink. To stay hydrated and avoid gastrointestinal issues, all water must be treated. The most environmentally friendly options are using water purification tablets/drops, a UV sterilizer, or a filter bottle. Boiled water can also be purchased at teahouses. Drinking 3-4 liters of water per day is crucial for proper acclimatization.
Your Mountain Companions: Guide and Porter Support
- Guide (Mandatory): The Upper Mustang trek is highly regulated, and solo trekking is not permitted, Hence a licensed guide is required by law. Beyond regulation, the guide is your most critical asset for safety, navigation, cultural interpretation, and logistical management. They bridge the language gap and provide invaluable insights into the Lo-pa culture.
- Porter (Highly Recommended): Hiring a porter is a practical decision that significantly enhances the trekking experience. A porter will carry the bulk of your gear (up to 18-20 kg), allowing you to walk with only a light daypack. This conserves your energy, reduces physical strain, and allows you to focus fully on the stunning scenery and cultural immersion.
Gearing Up: Essential Equipment Highlights
Key items specific to the challenges of Upper Mustang include:
- Layered Clothing System: A combination of moisture-wicking base layers, insulating mid-layers (fleece/down), and a windproof/waterproof outer shell.
- Footwear: Broken-in, sturdy trekking boots with good ankle support are essential.
- Face Protection: A buff, balaclava, or face mask is non-negotiable to protect against the persistent wind and dust.
- Sun Protection: High-altitude sun is intense. High SPF sunscreen, lip balm, a wide-brimmed hat, and UV-rated sunglasses are mandatory.
- Trekking Poles: Highly recommended for stability on rocky trails and to reduce stress on knees during long descents.

While this itinerary is a proven path, it can be customized to suit your specific interests or time constraints, including add-ons for the Tiji festival or more days in Lo Manthang.
