Nepal – Langtang Valley Gosaikunda Lakes Trek

Nepal – Langtang Valley Gosaikunda Lakes Trek


Langtang region, located to the north of the Kathamandu Valley and bordering Tibet, is the 3rd most popular trekking destination in Nepal, after Annapurna and Everest regions. This narrow valley, squeezed in between the main Himalayan range to the north and a slightly lower mountain range to the south, offers spectacular close-up views of  the snow-capped Himalayan range. Contain within the valley are the emerald green Gosaikunda Lakes (sacred to both Hindus and Buddhists) and Langtang Glacier (the longest glacier in the Himalyan range). The valley, though sparsely populated, has strong Tibetan influence with Buddhist monasteries dotted the valley. Despite its close proximity to Kathmandu, the Langtang region is surprisingly relatively uncrowded, making it an ideal trekking destination for those who wish to experience Nepal’s unique combination of cultures, landscape and mountain vistas yet without encountering the massive crowd of trekkers.

For those with less time to spare, are beginners or trekking with families, the shorter  11D Tamang Heritage Trek without venturing higher up the Langtang Valley is a good option. Or, the 16D Langtang Valley with Tamang Heritage Trek

About The Trek

The trek starts from Syabru Besi (1400m), heading up to the upper valley. The first two days of the trek are spent ascending from the gorge-like lower valley, passing an old moraine, before the trail opens up into a vast glacier valley with looming snow peaks. The highest rest point of this section of the trek is Kyanjin Gompa (3750m). We'll spend a day exploring Kyanjin Gompa, climbing up to the peak of the nearby Kyanjin Ri (4600m) and visiting the monastery and cheese factory. We then start our descend down the same trail before skirting to Sing Gompa (3250m) to start our ascend to Gosaikunda Lakes (4380m). Above Sing Gompa, the trail are above the tree line with panoramic views of the snow peaks. The trail goes upward to reach the barren upper reaches of the Trisuli River, where glacial moraines and rock slides have left a string of some half-dozen lakes (kund) to form the Gosaikunda Lakes. We spend a day exploring the lakes area before starting our descend southeast of Gosaikunda Lakes. We'll cross the Laurabina La Pass (4610m) and slowly making our way down to Sundarijal (1460m) during the last few days of our trek. The descend to Sundarijal is through a ridge, passing through lovely rhododendron and oak forests via Mangengoth (3390m) to Kutumsang (2470m), a Sherpa village where the Langtang National Park headquarters is based. Sundarijal (1460m), where there're frequent buses to Kathmandu is only 1 to 1.5hours drive away from Kathmandu.

Trekking Seasons

There are four main seasons in Nepal. The best seasons to visit Nepal are spring, autumn and winter. Trekkers can trek from March to early June in spring. The next trekking season starts in mid-September and goes up till March. During this period, the visibility is good and it does not rain usually. You can get excellent views of landscapes and mountain ranges in this season. After November the temperature in higher altitudes becomes very low and snowfall starts

Autumn (September to November): Autumn season is considered the best time for trekking in Nepal. It offers excellent weather and tantalizing mountain views. Moderate temperatures, clear sky with outstanding views, making it a great time to do any of our trek. Occasional short storms may dump snow at high altitudes.

Winter (December - February): Winter is when snowfall at higher elevations in the Himalayas is a common occurrence. Though it gets colder in night, it offers the clear day / blue sky and relatively less trekkers on the trail. However, not all treks are suitable to be done in winter especially those involving climbing and crossing high passes.

Spring (March - May): Different varieties of wild flowers, specially the rhododendrons make the hillside a wild flowers  paradise during the spring season. The temperature is warmer as compared to autumn and winter.

Experience Required

Good to have some high altitude trekking experiences. You will be trekking at above 3500m in undulating mountain terrain with a personal backpack load of 5-6kg for more than 10 days. The villages in Langtang region are further apart as compared to the Annapurna or Everest regions. The daily ascend and gain in elevation is thus much faster and higher.

Equipment and Gear

You will need thermal base layers, a fleece jacket and an outer shell jacket. When at the teahouse and after sundown, a down jacket will help keep you warm. A down sleeping bag is also needed and provided.

A packing list will be provided to all our participants. Please refer to our Resource Centre page to learn about the layering system and choose the right gear/equipment for your trek.

Training: Regardless of your level of fitness and physical conditions, it is advisable to train prior to embarking on a trekking or mountain climbing trip.

Pure cardiovascular fitness is NOT enough.

Focus your training effort in the following areas, assuming that you are in good health and injury-free:

  1. Climbing conditioning – stairs and load training.
  2. Cardio training - Jogging/running and interval training like CrossFit or HIIT.
  3. Strength training for the lower body, shoulder, back and core
  4. Flexibility training - eg: Yoga and stretching exercises

A good four months of training would be a good preparation for this trek.

A recommended training guide specific to the trek or climb will be given to you upon signing up.

Refer to our Grading chart for an overview on the technical difficulty and fitness required for this trek.
