Langtang Ganja La Pass Trek

You arrive at Tribhuvan International Airport in Kathmandu (1,400 m), where our representative meets you and transfers you to your hotel.

Your guide runs the pre-trek briefing. The Langtang Ganja La Pass trek is a serious undertaking — it combines the accessible and beautiful Langtang valley with a crossing of the Ganja La (5,122 m), a technical high pass that links Langtang to the Helambu region.

The pass is what sets this route apart. It frequently holds snow and ice, involves steep and exposed ground on both sides, and may require a rope and basic mountaineering equipment. The section beyond it is genuinely remote camping country with no lodges, so the trek is crew-supported from Kyanjin Gompa onward.

Your guide checks your equipment carefully — a four-season sleeping bag, crampons or microspikes, and proper layers are all necessary. The rest of the day is free to rest or walk around Thamel. Overnight in Kathmandu.

A long day on the road, around 120 km but taking seven to eight hours.

The route climbs out of the Kathmandu valley and heads north-west, and it is worth stopping at the Kakani ridge on a clear morning for the view of Ganesh Himal, Langtang and Manaslu along the horizon. The road then descends in long switchbacks toward the Trishuli river.

Beyond Trishuli Bazar the road turns north and begins climbing again toward Dhunche, the district headquarters and the checkpoint for Langtang National Park, where permits are registered. This upper section is spectacular and rough — a narrow track cut into steep hillsides with substantial drops, and the surface deteriorates as you climb.

From Dhunche the road descends to Syabrubesi (1,467 m), at the confluence of the Bhote Koshi and Langtang Khola. Overnight in Syabrubesi.

The first walking day, a climb of around 1,000 m up the Langtang valley through dense forest.

The trail crosses the Bhote Koshi and turns east up the Langtang Khola, following the river upstream. The lower valley is a deep, steep-sided gorge, and the path crosses the river several times on suspension bridges as it works its way up.

The forest here is excellent — oak, bamboo, pine and rhododendron, thick with moss and ferns, with the river loud below. This is good wildlife country: langur monkeys are common in the canopy and the birdlife is varied. Red pandas live in this valley, though sightings are very rare.

The climbing is sustained rather than steep, with several stiff sections in the afternoon.

Lama Hotel (2,470 m) is a cluster of lodges in a forest clearing rather than a village. Around 5–6 hours. Overnight at Lama Hotel.

A climb of around 980 m out of the forest and into the open upper valley.

The trail continues east beside the Langtang Khola, climbing steadily. The forest thins through the morning and by around 3,000 m the valley opens out, with Langtang Lirung (7,227 m) appearing above and glaciers visible at the head of the valley.

You pass Ghoda Tabela, an army post and checkpoint, and from there the landscape becomes pasture and scrub, with yaks grazing and the first mani walls, chortens and prayer flags marking the Tibetan Buddhist character of the upper valley.

Langtang Village (3,450 m) should be approached with some awareness of its history: the original village was completely destroyed by a landslide triggered by the 2015 earthquake, with heavy loss of life. What stands today has been rebuilt by the survivors, and there is a memorial to those who died.

Around 5–6 hours. Overnight in Langtang Village.

A short, gentle day of around 420 m to the highest permanent settlement in the valley.

The walking is easy by the standards of this trek and the day is deliberately short — it puts you at 3,870 m with a full afternoon to rest and acclimatise.

The trail climbs gradually through open alpine country, past yak pastures and some of the longest mani walls in Nepal — stone walls faced with carved prayer stones, which by custom you pass on the left. Chortens and prayer flags line the route, and the valley walls rise steeply on both sides.

Kyanjin Gompa (3,870 m) sits directly beneath Langtang Lirung (7,227 m) in a spectacular position at the head of the valley. There is an old Buddhist monastery here, a small cheese factory originally established with Swiss assistance, and views of the Lirung glacier tumbling off the mountain.

The afternoon is free to rest or walk gently. Around 3 hours. Overnight at Kyanjin Gompa.

An essential acclimatisation day before the Ganja La, and one of the best days of the trek in its own right.

The principle is climb high, sleep low, and there are two excellent options. Kyanjin Ri (4,773 m) is the shorter and steeper climb directly above the village, taking three to four hours return, with a panorama of Langtang Lirung, the glaciers and the whole valley. Tserko Ri (4,984 m) is longer and harder — six to seven hours return — but gives an even wider view east toward the Tibetan border peaks.

Either gets you around 1,000 m above sleeping height and back, which is exactly the preparation the pass requires.

Back in the village there is the monastery, the cheese factory and the glacier viewpoint. It is also the last day with lodges, shops and mobile signal.

Spend the evening preparing: the crossing ahead is technical and committing. Overnight at Kyanjin Gompa.

The trek leaves the Langtang valley and its lodges behind, climbing 560 m to the first camp beneath the pass.

The trail turns south out of Kyanjin, crosses the Langtang Khola and begins climbing the valley's southern wall. Within an hour the well-trodden main route is behind you and the character of the trip changes completely — from a teahouse trek to a supported camping expedition in empty country.

The climb is steady over open ground, and there is no vegetation to speak of beyond grass and low scrub. Behind you the whole Langtang valley opens out, with Langtang Lirung and its glaciers directly opposite.

This is high pasture where yaks are grazed in summer, and blue sheep are often seen on the slopes above.

Nyengang Kharka (4,430 m) is a herders' grazing ground with no permanent structures — the crew pitches camp. It is cold and exposed. Around 4–5 hours. Overnight camping at Nyengang Kharka.

Today is the most challenging and adventurous day of the trek as you cross the high Ganja La Pass. Begin early because the route involves steep and rugged terrain, and conditions around the pass can change quickly.

The trail climbs steadily through rocky alpine terrain toward the pass. As you approach Ganja La, the path can become steep and challenging, particularly if snow or ice is present. Reaching the top at 5,130 m is a major achievement and rewards you with spectacular views of the surrounding Himalayan peaks and remote valleys.

After spending some time at the pass, begin the long descent toward Keldang. The trail gradually becomes less steep as you move into the remote Helambu landscape. Arrive at Keldang after a demanding day and rest well.

A long day on a high, remote ridge, with less climbing than yesterday but sustained walking at altitude.

After the effort of the pass crossing, today's profile is gentler in net terms — a loss of around 230 m — but the trail undulates persistently along a high ridge system, climbing and dropping across a series of spurs, so the actual work is more than the figures suggest.

This is the most isolated stretch of the trek. There are no settlements, no lodges and no reliable water for long sections, so the crew carries everything. You are unlikely to see another group.

The compensation is the position. The trail follows open ridgelines with views in every direction — north back toward the Langtang peaks, and south over the ranges and valleys of Helambu. Blue sheep and Himalayan griffons are common.

Dhukpa (4,040 m) is another exposed camping ground. Around 6–7 hours. Overnight camping at Dhukpa.

A long descent of around 1,450 m that brings you off the high ridges and back into inhabited country.

The trail drops steadily south, and the transformation over the course of the day is dramatic. You start on bare alpine ridge with no vegetation, pass through juniper and stunted rhododendron, then into proper rhododendron and oak forest, and finish among terraced fields and houses.

The descent is sustained and hard on the knees — poles are worth using — but the return of oxygen, warmth and greenery after several days above 4,000 m is a considerable relief.

Tarkeghyang (2,590 m) is the largest and most important village in Helambu, and a genuinely interesting place to arrive. It is a Sherpa settlement — the Helambu Sherpa are distinct from those of the Khumbu — with traditional stone houses, an old gompa, mani walls and prayer flags, set on a hillside among apple orchards.

Around 6–7 hours. Overnight in Tarkeghyang.

An easy, level day along the Helambu ridge — a genuine rest after the high country.

The net height change is negligible, and the trail contours along the hillside rather than climbing or descending significantly. After the demands of the pass and the ridge camps, this is a pleasant walk rather than a day's work.

The route runs through pine and rhododendron forest, past terraced fields, apple orchards and a string of small Sherpa and Tamang settlements. There are gompas, chortens and mani walls throughout — Helambu is strongly Buddhist and the religious architecture is everywhere along the trail.

On a clear day the views north take in the Langtang range, including the peaks around the pass you crossed, and east toward Dorje Lakpa.

Sermathang (2,610 m) is an attractive village on a broad ridge with an old monastery and wide views over the Melamchi valley. Around 4–5 hours. Overnight in Sermathang.

The final walking day, a long descent of more than 1,700 m to the roadhead.

The trail drops steadily off the Helambu ridge, losing height continuously through the day. The landscape changes accordingly: pine and rhododendron forest gives way to terraced farmland, then to the warm, green, densely cultivated country of the lower valley, with rice paddies and banana palms near the bottom.

The route passes through a series of villages and the walking is on well-used paths, shared with local people going about their day. It is a good final stage for taking in ordinary rural Nepal after two weeks in the mountains.

The heat is noticeable by the afternoon — from a camp at 4,040 m three days ago to under 900 m is a substantial change.

Melamchi Pul Bazar (870 m) is a busy market town on the Melamchi river, and the roadhead where the trek ends. Around 5–6 hours. Overnight in Melamchi Pul Bazar.

The drive back to the capital, around 80 km and four to five hours.

The road follows the Melamchi and then the Indrawati river valleys south-west before climbing toward the Kathmandu valley rim. It is a scenic route through terraced farmland, riverside settlements and green hills, and the surface is mixed — rough in sections, sealed closer to the city.

This is also the corridor of the Melamchi Water Supply Project, the long-running scheme that pipes water from this valley to Kathmandu, and you will see elements of the infrastructure along the way.

As you approach the capital the landscape becomes progressively more built up.

You arrive in Kathmandu (1,400 m) and transfer to your hotel. The evening is free — a hot shower after nearly a week of camping, and time for a farewell dinner with the guide and crew. Overnight in Kathmandu.

The last day of the Langtang Ganja La Pass Trek.

Depending on your flight time there may be free hours in the morning. Thamel is the obvious place for last-minute shopping, and Boudhanath — the great stupa at the centre of Kathmandu's Tibetan Buddhist community — connects directly to the gompas and mani walls of Langtang and Helambu.

Our representative collects you from your hotel and transfers you to Tribhuvan International Airport around three hours before departure.

You leave having completed one of the more demanding routes in central Nepal: the full Langtang valley to Kyanjin Gompa, the technical crossing of the Ganja La (5,122 m), several days of remote ridge camping with no lodges or settlements, and a descent into the Sherpa villages of Helambu.
