The Annapurna to Mustang Traverse via Teri La Pass is one of Nepal’s most remote and challenging high-altitude trekking expeditions, linking the secluded valleys of the Nar Phu Valley with the restricted Himalayan kingdom of Upper Mustang. Operated by Mountain of Nepal, this 23-day journey is designed for experienced trekkers seeking adventure beyond traditional routes in the greater Annapurna region. The trek passes through isolated Tibetan-influenced settlements, high mountain passes, ancient monasteries, and stark trans-Himalayan landscapes, culminating in the legendary walled city of Lo Manthang.
The itinerary begins in Kathmandu and progresses through the Annapurna Circuit trailhead at Koto before entering Nar Phu Valley. From there, the route climbs steadily through Kyang, Phu Gaun, Nar, and onward to high alpine camps before crossing the demanding Teri La Pass (5,540 m). After the pass, the trail descends into Mustang, eventually reaching Upper Mustang and concluding at Jomsom, followed by flight connections back to Pokhara and Kathmandu.
This expedition is both a cultural immersion and a physical challenge, combining wilderness trekking with high-altitude endurance. Mountain of Nepal ensures full logistical support, including experienced guides, permits, and safety management for this remote Himalayan traverse.
The best seasons for the Annapurna to Mustang Traverse via Teri La Pass are spring (April–May) and autumn (September–November). During these periods, weather conditions are relatively stable, skies are clearer, and mountain views are at their best. Because the route crosses extremely high terrain, including Teri La Pass and remote sections of the Annapurna and Mustang regions, weather plays a critical role in safety and success.
In spring, rhododendron forests bloom in the lower Annapurna regions, while higher valleys like Nar Phu Valley remain crisp and dry. Autumn offers the clearest visibility and most stable trekking conditions, especially in the rain-shadow areas of Upper Mustang. Winter is not recommended due to heavy snowfall blocking Teri La Pass, while summer/monsoon brings landslides in the lower sections near Annapurna approaches.
Mountain of Nepal carefully selects departure dates to align with optimal weather windows and ensures contingency days in locations like Nar Gaon for acclimatization and weather delays.
Seasonal summary:
This trek is classified as very strenuous to expedition-level difficulty due to long trekking days, high altitude exposure, and technical navigation across remote terrain. The highlight, Teri La Pass (5,540 m), requires strong physical endurance and prior trekking experience above 4,000 meters. Daily walking ranges between 3 and 9 hours, often on rugged, unmarked trails with significant elevation gain and loss.
Transportation begins with arrival in Kathmandu, followed by a long road drive to Koto. The trek then continues on foot through isolated valleys, with no road access until lower Mustang. After reaching Jomsom, travelers take a short mountain flight to Pokhara, followed by a drive or flight back to Kathmandu. Mountain of Nepal arranges all ground logistics, domestic flights, permits, and emergency evacuation support if required.
The route requires acclimatization days in Phu and Nar to reduce altitude sickness risks. Terrain includes glacier-fed rivers, rocky ascents, snow passes, and high desert plateaus.

Transport summary:
Accommodation on this route is a combination of basic teahouses, homestays, and high-altitude camping. In lower sections, such as Annapurna approach villages, simple lodges provide meals and bedding. However, once entering Nar Phu Valley and approaching Teri La Pass, camping becomes essential due to the lack of permanent settlements. Mountain of Nepal provides full camping equipment, including tents, kitchen support, and trained cooks for higher camps.
Meals are typically Nepalese and Tibetan-influenced, including dal bhat, noodles, soups, tsampa, and seasonal vegetables. As altitude increases, food becomes simpler but energy-rich. In remote sections like Upper Mustang, local lodges offer basic but warm meals. Hydration and calorie intake are strictly managed by guides to maintain stamina at altitude.
Hygiene conditions vary depending on remoteness. In teahouses, shared bathrooms are common, while camping sections rely on portable toilet systems managed by the crew.
Food & accommodation highlights:
Mountain of Nepal ensures safe food handling, hygienic cooking, and proper altitude nutrition planning throughout the expedition.
This trek passes through restricted and protected areas, requiring multiple official permits issued by the Government of Nepal. Since it includes both the Annapurna Conservation Area and the restricted Upper Mustang region, proper documentation is mandatory and strictly checked at various checkpoints.
The key permits include the Annapurna Conservation Area Permit (ACAP), Restricted Area Permit (RAP) for Nar Phu Valley, and the Upper Mustang Restricted Area Permit. Additionally, special trekking arrangements are required for crossing Teri La Pass, as it lies in a remote high-altitude corridor between two restricted zones.
Mountain of Nepal handles all permit processing on behalf of trekkers, ensuring compliance with Nepal Tourism Board regulations. Solo trekking is not permitted in restricted areas; therefore, a licensed guide and minimum group requirement apply.
Permit summary:
Permits ensure environmental protection, cultural preservation, and controlled tourism in fragile Himalayan regions like Upper Mustang and Nar Phu Valley.

The Annapurna to Mustang Traverse via Teri La Pass is a challenging high-altitude expedition that connects the lush Annapurna region with the arid landscapes of Upper Mustang through the remote Nar Phu Valley and the high Teri La Pass. Organized by Mountain of Nepal, this trek is considered one of the most adventurous routes in Nepal due to its isolation, high passes, and cultural diversity. It combines classic Himalayan trekking with expedition-style camping. Trekkers experience dramatic changes in landscapes, from green valleys and glaciers to Tibetan-influenced deserts, making it a rare and rewarding Himalayan traverse.
This traverse is graded as extremely challenging, suitable only for experienced trekkers with strong physical fitness and prior high-altitude trekking experience. The route includes long trekking days, remote wilderness, and crossing the high Teri La Pass at 5,540 meters. Because of the altitude and isolation, mental endurance is equally important. Mountain of Nepal recommends that participants have previous experience above 4,000 meters and are comfortable with camping conditions. Beginners are generally not advised. Proper preparation, acclimatization, and guided support are essential for safety throughout the journey.
Altitude sickness is a major concern on this route due to prolonged exposure above 4,000 meters and the crossing of Teri La Pass at extreme altitude. Mountain of Nepal incorporates a carefully designed acclimatization schedule, including rest days in places like Nar Gaon. Trekkers are closely monitored for symptoms such as headaches, nausea, or dizziness. Guides are trained in first aid and emergency response. Gradual ascent, hydration, and proper pacing are strictly enforced. In severe cases, descent is prioritized immediately to ensure safety.
Connectivity is extremely limited throughout the Annapurna to Mustang Traverse. While mobile networks may work occasionally in lower villages such as Koto or Jomsom, most of the route, especially in the Nar Phu Valley and high pass regions, has no reliable signal. Internet access is almost nonexistent in camping zones. Mountain of Nepal advises trekkers to inform family in advance about communication gaps. Satellite communication is sometimes used by guides for emergency purposes. This disconnect from technology is part of the raw wilderness experience of the trek.

In villages like Lo Manthang, trekkers may find simple guesthouses. Comfort is secondary to the adventure experience in this remote Himalayan environment.
Food during the expedition is prepared by the support crew of Mountain of Nepal, focusing on high-energy meals suitable for high-altitude trekking. In lower regions like Phu Gaun and villages in Upper Mustang, trekkers may enjoy traditional Nepali and Tibetan-style meals. During camping sections, meals include rice, pasta, soups, lentils, vegetables, and occasional meat when available. Snacks, tea, and energy foods are also provided daily.
