Langtang Valley Trek

Syabrubesi (1,550 m) is a Tamang market town on the Bhote Kosi river in Rasuwa district, 117 km from Kathmandu by private jeep. The Langtang National Park gate sits 2 km above the village; permits are checked here and again at the Ghoda Tabela army checkpost (3,030 m). Above the gate the trail enters sub-tropical and temperate forest of rhododendron, oak, and bamboo along the Langtang Khola gorge. Red pandas (Ailurus fulgens) have been documented in this zone between 1,800 m and 3,800 m; early morning walking between Syabrubesi and Lama Hotel produces the highest probability of a sighting on the route.

Bamboo (1,970 m) is a teahouse cluster in a bamboo-forested section of the gorge, the overnight stop added on the 16-day schedule. Lama Hotel (2,470 m) sits at the upper edge of the dense forest at a river bend where the valley begins to widen. The stage from Lama Hotel to Langtang Village (3,430 m) gains 960 m through thinning forest and open pasture past Ghoda Tabela, crossing the Langtang Khola on suspension bridges. Langtang Village was rebuilt between 2016 and 2018 following the 2015 earthquake; the memorial garden is on the debris field side of the settlement.

Langtang Village to Kyanjin Gompa (3,870 m) is a 6 km walk on a flat valley floor through yak pastures and mani walls, reaching the monastery in 3 to 4 hours. Langtang Lirung (7,227 m) is directly visible to the north above the glacier terminal moraine. The Kyanjin Gompa monastery dates to the 18th century and is in daily active use. The adjacent cheese factory, established in 1955 with Swiss development assistance, sells hard yak-milk cheese by the block at the factory door.

Tsergo Ri, also spelled Tserko Ri, stands at 4,984 m / 16,352 ft on the east side of the Kyanjin Gompa basin. The ascent begins from Kyanjin (3,870 m) and gains 1,114 m on a route that is steep but non-technical: grass slopes to approximately 4,400 m, then scree and loose rock to the broad summit ridge. A fit, acclimatised trekker reaches the top in 4 to 5 hours; descent takes 2.5 to 3 hours. Total time from Kyanjin including rests is typically 7 to 8 hours.

The summit panorama covers the Langtang Himal in full: Langtang Lirung (7,227 m) fills the north horizon; Dorje Lakpa (6,966 m) stands to the east above the Jugal Himal border; Shishapangma (8,027 m), the only 8,000 m peak lying entirely in Tibet, is visible on clear days 65 km to the north-west. The Langtang Glacier is fully visible below Kyanjin, and the Langshisha Glacier further east can be traced up the valley from the summit ridge.

Departure from Kyanjin for Tsergo Ri is 4:30 to 5:00 am, before afternoon wind increases above 4,500 m. Required kit: headlamp, warm layers, trekking poles, packed lunch, and 2 litres of water. Swotah guides carry a pulse oximeter and check SpO2 before departure; a reading below 80 percent at rest is grounds for postponing. On the 16-day itinerary this is Day 8, after two nights already at Kyanjin and one Kyanjin Ri day confirming acclimatisation.

Langshisha Kharka (4,084 m) is a high seasonal grazing pasture 9 km east of Kyanjin Gompa, reached by following the Langtang Khola upstream along the north edge of the Langtang Glacier. 'Kharka' is the Nepali word for a high seasonal yak pasture; this one sits below the west face of Langshisha Ri (5,693 m / 18,678 ft) and is used by herder families from July to October. Most Langtang trekkers turn back at Kyanjin; the Langshisha day extends the route into terrain that sees a fraction of the visitor numbers at the valley head.

The trail from Kyanjin to Langshisha Kharka is mostly flat, crossing glacial meltwater streams on log bridges and passing the terminal and lateral moraines of the Langtang Glacier. The altitude gain is 214 m over 9 km. Eastward views of the Jugal Himal, including Dorje Lakpa (6,966 m), are the clearest visible from ground level on the entire route. The round trip from Kyanjin Gompa takes 5 to 6 hours.

Langshisha Kharka falls on Day 9 of the itinerary, the day after Tsergo Ri. The flat valley walk acts as active recovery before the three-day descent begins. No overnight accommodation exists at Langshisha Kharka; both the night before and the night after are at Kyanjin Gompa (3,870 m).

Two permits are required for the 16-day Langtang Valley Trek. The Langtang National Park entry permit costs NPR 3,000 (approximately USD 23) per person for non-SAARC nationals. Langtang National Park was established in 1976 and covers 1,710 km2 of Langtang, Ganesh, and Jugal Himalayan ranges. The park gate above Syabrubesi and the Ghoda Tabela army checkpost (3,030 m) both verify the permit on trail. The TIMS card (Green TIMS for non-restricted routes) costs NPR 2,000 per person when trekking with a registered agency. Swotah processes both in Kathmandu before departure; both are included in the trip cost.

Documents required for permit processing: passport with 6-month validity, two passport-size photographs, Nepal visa copy, and travel insurance certificate. Total permit cost is approximately NPR 5,000 (USD 38) per person. The Langtang Valley route, including the Langshisha Kharka extension, is a standard non-restricted area. No additional special permit is needed beyond the pair above. Trekkers adding the Ganja La Pass crossing (Swotah trip 103) require a separate permit not covered here.

Nepal entry visa: USD 30 for 15 days or USD 50 for 30 days, available on arrival at Tribhuvan International Airport. Swotah does not arrange visas but covers the process in pre-departure briefing materials.

Acute mountain sickness (AMS) occurs when the body cannot acclimatise fast enough to reduced atmospheric oxygen. The 16-day Langtang itinerary includes three design features that reduce AMS risk compared to faster schedules. First, the Bamboo (1,970 m) overnight limits Day 3 altitude gain to 420 m, keeping the first two acclimatisation days below 2,500 m. Second, three consecutive nights at Kyanjin Gompa (3,870 m) before any summit attempt allow the body to adapt; International Society for Mountain Medicine guidelines recommend a minimum of two nights before ascending to a new altitude tier. Third, the summit days return to 3,870 m each night, following 'climb high, sleep low' throughout the high-altitude section.

Common early AMS symptoms: persistent headache, nausea, fatigue, disturbed sleep. If any worsen over 12 hours at the same altitude, descend 500 m immediately. Swotah guides carry pulse oximeters, Acetazolamide (Diamox), and Dexamethasone. SpO2 readings are checked each morning above 3,000 m and before summit departures. Trekkers who choose to take Diamox prophylactically should consult their physician before departure; the standard preventive dose is 125 mg twice daily starting 24 hours before ascent.

Travel insurance covering helicopter evacuation to 5,000 m is required. A helicopter from Kyanjin Gompa to Kathmandu takes approximately 25 to 30 minutes. The Kyanjin landing pad operates year-round. Confirm that your policy explicitly covers helicopter evacuation at altitude; general travel policies often exclude this even when they cover emergency medical treatment.

The Tamang are one of Nepal's largest indigenous ethnic groups and the primary community of the Langtang Valley and Rasuwa district. Tamang society follows Tibetan Buddhism mixed with local animist traditions; prayer flags, mani walls (stone slabs carved with 'om mani padme hum'), chortens, and active gompas appear from Syabrubesi onward. The Tamang language belongs to the Tibeto-Burman family; most teahouse owners in the valley speak Tamang, Nepali, and basic English. The Kyanjin Gompa monastery, dating to the 18th century, is maintained by a resident monk and receives morning puja attendance from the local community throughout the year.

The April 25, 2015 earthquake (7.8 Mw) triggered a rockfall and ice avalanche from Langtang Lirung's south face that buried the upper half of Langtang Village within minutes. Of the 243 people killed, 175 were Tamang residents and 68 were foreign trekkers. The rebuilt settlement was completed between 2016 and 2018; a memorial garden at the debris field boundary names those who died. Many teahouse owners in Langtang Village and Kyanjin Gompa lost immediate family members; your guide provides context when the group passes through.

Cultural courtesies: remove shoes before entering monasteries and homes; walk clockwise around mani walls and stupas; ask before photographing religious items or ceremonies. Tipping guides and porters is standard: USD 10 to 15 per day for the guide, USD 5 to 8 per day for the porter, paid at the end of the trek in Kathmandu.

Every overnight stop on the 16-day route has teahouse accommodation. All stops except Bamboo have been rebuilt since 2015 and standards are solid. Room quality ranges from basic plywood-partition twin rooms with shared squat toilet at Bamboo to stone-wall rooms with attached Western toilet at upper-end Kyanjin Gompa lodges. Private rooms with attached bathrooms are available at Syabrubesi and some Kyanjin teahouses for a supplement.

Notes by stop: Bamboo (1,970 m) has 4 to 5 teahouses with basic twin rooms and no reliable electricity for device charging. Lama Hotel (2,470 m) has a wider selection with solar charging and warm common rooms; hot showers cost NPR 150 to 200. Langtang Village (3,430 m) has post-earthquake lodges with clean rooms. Kyanjin Gompa (3,870 m) has the most choice: electric blankets, solar water heating, and the widest menu on the route; hot showers cost NPR 200 to 300. A sleeping bag rated to -10 degrees Celsius is required above Lama Hotel; -15 degrees is recommended from October through April at Kyanjin.

Teahouse menus follow the standard Nepal trekker format throughout the route. Dal bhat (lentil soup with rice and vegetable curry, free refills) is the highest-value item at every stop; it costs NPR 400 to 500 at Lama Hotel and NPR 700 to 900 at Kyanjin Gompa. All menus include Tibetan bread, momos, fried rice, noodle soup, pasta, omelette sets, and porridge. Kyanjin Gompa adds yak-milk products from the 1955 cheese factory: hard cheese, yak butter tea, and curd. Avoid meat above 3,000 m; protein freshness at altitude is unreliable and digestion adds physiological load at reduced oxygen levels.

Tap water is not safe on any section of the route. Boiled water costs NPR 50 to 80 per litre at lower stops and NPR 100 to 150 at Kyanjin. The preferred personal option is purification tablets (Aquatabs or Micropur) or a SteriPen UV purifier. Target 3 to 4 litres of fluid daily above 3,000 m. Single-use plastic bottles cost NPR 100 to 200 per litre above Lama Hotel.

Nepal Telecom (NTC) provides the most consistent signal. Ncell 4G covers Syabrubesi and the lower valley to Lama Hotel; NTC 3G is available at Kyanjin Gompa, slow and intermittent. WiFi is available at Lama Hotel and Kyanjin teahouses for NPR 200 to 500 per session. Device charging costs NPR 200 to 300 at solar lodges. Bring a 20,000 mAh power bank for 11 trek days. Connectivity is limited from Day 5 through Day 12.
