Langtang, Gosaikunda and Helambu treks compared

Langtang National Park, set up in 1976 as Nepal's first Himalayan national park, starts barely 30 km north of Kathmandu. Its southern edge touches Shivapuri Nagarjun National Park, which sits right on the city's rim, and between them lie some of the most accessible mountain walks in the country. You do not need a flight. Every trek in this guide starts and ends with a drive, most of them along the Pasang Lhamu Highway to Dhunche and Syabrubesi, or out to Sundarijal on the edge of the valley.

That shared geography makes the treks easy to confuse. They overlap, they join up and they are often sold under different names. In practice there are six main options: the Langtang Valley to Kyanjin Gompa, the Langtang Valley combined with Gosaikunda, the Gosaikunda and Helambu traverse, a short Helambu trek, the Tamang Heritage Trail and the Chisapani to Nagarkot rim walk. Each suits a different kind of traveller, and each has a different high point, in every sense.

The table gives our standard version of each trek. Nights count from Kathmandu and back, and the maximum altitude is the highest point you reach on foot, not where you sleep. Grades are ours: easy means anyone who walks regularly; moderate means long days on hills; challenging means long days plus real altitude or a pass. Prices for each are on the journey pages.

If you have a week and want snow peaks close up, this is the one. From Syabrubesi at 1,460 m the trail follows the Langtang Khola east through oak, rhododendron and bamboo forest, past Lama Hotel and Ghoda Tabela, into an open glacial valley. Langtang village, buried by an avalanche in the 2015 earthquake and since rebuilt beside the debris, is the last big settlement. Kyanjin Gompa, at 3,870 m, sits among yak pastures under Langtang Lirung, with a cheese factory first set up with Swiss help in the 1950s.

The walking is steady rather than steep, lodges are frequent and reasonably comfortable, and there is no pass to cross. Most people spend two nights at Kyanjin and climb Kyanjin Ri at dawn, or Tserko Ri, at 4,984 m, for a longer day. The weakness is that you return the way you came, which some walkers mind and others do not. The forest feels different on the way down.

Gosaikunda is a sacred lake at 4,380 m on the ridge south of the Langtang valley, one of a chain of lakes that together form a Ramsar wetland. Hindu tradition holds that Shiva made it with his trident, and every year on Janai Purnima, the full moon of Shrawan, thousands of pilgrims climb here. Outside the festival it is a quiet, stark place of rock, water and prayer flags.

You can reach it three ways. From Dhunche, the direct route climbs fast, from 1,960 m to 4,380 m in three days, so we add a night at Laurebina. From the Langtang Valley, via Thulo Syabru and Sing Gompa, you arrive already acclimatised, which is why we like the 12-night combination. Or you can cross the lake region as part of a traverse: over the Laurebina La at 4,610 m, down through Ghopte and Tharepati and into Helambu, the home of the Hyolmo people.

That traverse is our favourite route in the region for fit walkers. It has the drama of the pass and the lakes, then the softer, village-led days of Helambu, with old gompas, apple orchards and family lodges. The pass section between the Laurebina La and Ghopte is remote and easy to get lost on in cloud, so treat it with respect.

Helambu on its own makes a fine short trek. You walk out of the Kathmandu valley at Sundarijal, sleep at Chisapani with a view of Langtang and Jugal, follow the ridge to Kutumsang and Tharepati, and drop to Melamchi Gaon and Tarkeghyang. The highest point is 3,640 m, the trailhead is under an hour from Thamel, and the route works well in winter, when higher treks are cold and snowy. Lodges are simpler than in Langtang.

The Tamang Heritage Trail is a loop through the Tamang villages west of Syabrubesi: Gatlang, Tatopani with its hot springs, the meadow of Nagthali at 3,165 m, Thuman and Briddim. It was set up as a community route in the mid-2000s, and nights are mostly in homestays. Choose it if the people interest you as much as the peaks. It can be joined to the Langtang Valley by a forest trail from Briddim, making a two-week trip with very different halves.

If you have only three or four days, the hills around Kathmandu are worth more than most people think. The Chisapani to Nagarkot walk climbs from Sundarijal through Shivapuri Nagarjun National Park, follows farm paths and forest east along the rim, and descends past Changunarayan, the valley's oldest temple, to Bhaktapur. Views of the Himalaya are excellent from October to February. It is a good first taste of Nepal's trails for families, or a way to fill a gap before a longer trek.

Comfort varies more than the maps suggest. The Langtang Valley has the best lodges in the region: twin rooms with proper mattresses, solar hot showers in most villages, paid wifi in many and long menus from dal bhat to pizza. Kyanjin Gompa has the widest choice of lodges in the valley. On the Gosaikunda trail, lodges at Sing Gompa, Laurebina and the lake are fewer and simpler, and they fill quickly around Janai Purnima.

Helambu and the Tamang Heritage Trail are a step more basic. Many places are family homes with a few rooms, shared squat toilets and meals cooked in the family kitchen, and hot showers are a bonus rather than a given. In return you get conversation, home cooking and a clearer sense of how people live. On every route, rooms are unheated, so a good sleeping bag matters more than anything else you pack. Above 3,500 m, expect water bottles to freeze on clear nights from November to March.

Start with time and altitude, then think about what you want to remember. Every option below needs a licensed guide in national parks under rules in force since April 2023; check current status before you travel.

• Seven to nine days and big mountains: the Langtang Valley to Kyanjin Gompa.
• Twelve days and good fitness: Langtang Valley with Gosaikunda, for the best acclimatisation.
• Nine or ten days and a sense of journey: Gosaikunda over the Laurebina La to Helambu.
• Winter, a first trek or a short break: Helambu from Sundarijal.
• Village life and homestays at modest height: the Tamang Heritage Trail.
• Three days, children or a stopover: Chisapani to Nagarkot and Bhaktapur.
• Janai Purnima in July or August: Gosaikunda from Dhunche, accepting monsoon rain.
