Why book the Langtang Gosainkund and Helambu trek?
This 19-day DIFFICULT-graded trek from Kathmandu to Kathmandu takes you through three of Nepal's most varied and rewarding Himalayan landscapes in a single journey. You walk through ancient oak and rhododendron forests past the poignant ruins of Langtang village (destroyed in the 2015 earthquake), spend three nights at Kyangjin Gompa at 3,849m with the option to ascend Tsergo Ri (4,984m) for views of Langtang peak (7,227m) and Shisha Pangma (8,027m), cross the sacred Gosainkund lake at 4,361m (a major Hindu pilgrimage site), cross the Llaurebena Pass at 4,610m, and descend through the green Helambu Valley to Kathmandu. Groups run 2-12, with a porter, trekking equipment hire (down jacket, sleeping bag, walking poles), and all lodge meals included.
Is this trek suitable for first-time trekkers?
Not ideal for complete beginners. The DIFFICULT grade and 4,610m maximum altitude mean you need prior trekking experience or excellent fitness and mental preparation. Strong hikers who have completed multi-day walks at home can consider it with proper preparation. If this is your first Himalayan trek, the Langtang and Tamang Heritage Trek (15 days) at a lower altitude is a better starting point.
What is the difference between this and your other Nepal treks?
Langtang, Gosainkund and Helambu is a 19-day DIFFICULT circuit reaching 4,610m. The Langtang and Tamang Heritage Trek (15 days) is shorter and lower-altitude. The Annapurna Circuit and Nar Phu Valley (21 days) and Everest and Gokyo Lakes (20 days) are longer, comparable-difficulty alternatives. This trek is distinctive for combining three separate Himalayan valleys in one continuous journey.
What is the best time of year to do this trek?
October to November is the prime season: clear skies, spectacular mountain views, and settled weather. March to April is excellent with rhododendrons in bloom. Avoid June to September: the monsoon makes trails muddy and views are obscured. We strongly recommend against the monsoon period for this grade of trek.
Why does this trek cost what it does?
At 19 days this is a substantial expedition. Included are 18 nights accommodation (2 nights 3-star hotel in Kathmandu plus 14 nights trekking lodges in the mountains), 18 breakfasts, 14 lunches, 13 dinners at lodge level, trekking equipment hire (down jacket, sleeping bag rated for altitude, walking poles), a porter (carrying up to 12.5kg of your gear), all transport and transfers, and an experienced English-speaking guide. This is a full expedition at a genuinely inclusive price.
What is actually included in the price?
Included: 2 nights at Thamel Park Hotel Kathmandu (3-star), 14 nights in trekking lodges, trekking equipment hire (down jacket, sleeping bag, walking poles), porter (max 12.5kg per porter bag), all transport and transfers, English-speaking guide, 18 breakfasts, 14 lunches, 13 dinners, and all permits and entrance fees.
What is NOT included and how much extra should I budget?
International flights, Nepal visa, travel insurance (must cover helicopter evacuation to 4,610m+), tips, drinks, personal trekking gear (boots, layers), extra drinks and snacks at lodges, and any optional extras. Your guide will brief you on current tipping norms at the start.
Can I pay in instalments?
Yes. Pay a deposit to secure your place and the balance 8 weeks before departure.
How physically demanding is this trek?
DIFFICULT. Trekking days range from 4-7 hours of walking at altitude. The Llaurebena Pass at 4,610m is the highest point and is genuinely challenging. You need to be fit, experienced at sustained uphill walking, and able to cope with altitude. Good cardiovascular fitness before departure is essential.
What if I am older than the rest of the group?
Altitude affects people regardless of age, and experience and acclimatisation matter more than youth. Fit, experienced trekkers in their 50s and 60s complete this trek regularly. The key is honest self-assessment of your altitude tolerance and fitness level.
What if I have mobility issues or a medical condition?
This is not a suitable trek for anyone with significant cardiovascular, respiratory, or mobility conditions. The combination of altitude (up to 4,610m) and long trekking days means any pre-existing condition can be seriously exacerbated. Consult your doctor before booking.
How do you handle altitude sickness?
Acute Mountain Sickness (AMS) is a genuine risk above 3,500m. Your guide provides a full AMS briefing before and during the trek. The itinerary includes built-in acclimatisation days at Kyangjin Gompa. If symptoms are serious, the protocol is to descend immediately. Your travel insurance must cover helicopter evacuation from the maximum altitude of 4,610m.
Is Nepal safe to visit right now?
Nepal is a safe, well-established trekking destination. The main safety consideration on this specific trek is altitude-related illness, which is managed through proper acclimatisation and your guide's AMS protocols.
Is it safe for women travelling solo?
Nepal is safe for solo female trekkers, particularly on a guided group trip where you are accompanied by an experienced guide throughout.
What happens in a medical emergency at altitude?
If a trekker develops serious AMS symptoms, the guide will arrange immediate descent and, where necessary, a helicopter evacuation. This is why travel insurance covering helicopter evacuation to 4,610m+ is not optional but critical. Your guide carries emergency oxygen and a pulse oximeter.
What is the accommodation actually like?
In Kathmandu you stay at the 3-star Thamel Park Hotel. On the trek itself, you stay in trekking lodges (also called tea houses): simple wooden or stone structures with twin rooms (some en-suite, some shared bathrooms at higher altitudes), electricity, and communal dining rooms serving hot meals and drinks. They are basic but warm and welcoming.
What is sleeping in a trekking lodge like?
Trekking lodges are the lifeblood of the Himalayan trail system. Rooms are simple with wooden beds, blankets, and often a window with mountain views. Bathrooms may be shared at higher altitudes. Your hired sleeping bag keeps you warm. The communal dining room, heated by a central stove, is where you eat, socialise, and acclimatise with fellow trekkers.
Will I have Wi-Fi?
Thamel Park Hotel in Kathmandu has Wi-Fi. Lower-altitude lodges may have Wi-Fi or mobile signal. Above Kyangjin Gompa (3,849m) and at Gosainkund (4,361m) connectivity is unreliable or absent.
Can I upgrade?
Kathmandu pre and post-trek nights can be upgraded. On the trek itself, lodge accommodation is fixed by the trail infrastructure. Extra nights in Kathmandu are available as an optional add-on.
What kind of food will we eat?
Trekking lodge food is hearty and carbohydrate-heavy, which is exactly what you need at altitude. Dal bhat (lentils and rice) is the Nepalese staple and the most calorie-efficient meal on the trail. You will also find pasta, noodles, omelettes, pancakes, and fresh soup. 18 breakfasts, 14 lunches, and 13 dinners at the lodges are all included.
Can you cater for vegetarian vegan or gluten-free diets?
Vegetarian food is the norm on Nepal's trekking trails. Vegan is manageable (dal bhat is naturally vegan). Gluten-free is harder in remote lodges. Inform us when you book.
Is it safe to drink the water?
Do not drink untreated water on the trail. Use the hot boiled water served at lodges, purification tablets, or a Water-to-Go filter bottle. Reducing plastic bottle use is important in fragile mountain environments.
Is this trek good for solo travellers?
Excellent. The small group size of 2-12 and the intensity of a 19-day trek creates strong bonds. Many solo trekkers find this one of the most socially rewarding travel experiences they have had.
Do I have to share a room?
The price is based on twin-sharing at the Kathmandu hotel and in trekking lodges. A single supplement is available for Kathmandu nights. In lodges at very high altitudes, single rooms may not be guaranteed.
What is the group size and who else will be on the trek?
Groups run 2-12. Expect experienced trekkers, likely 30-60 years old, who have done some walking before and are motivated by both the physical challenge and the cultural depth of the Langtang and Helambu valleys.
Can I book this as a private trek?
Yes. Private departures on flexible dates are available. Contact our sales team.
Is this trek suitable for kids?
The minimum age for this trek is 15. The DIFFICULT grade and altitude make it unsuitable for younger children.
Do I need a visa for Nepal?
Most nationalities can obtain a tourist visa on arrival at Tribhuvan International Airport in Kathmandu. Check current fees on the Nepal immigration website before you travel.
What should I pack?
Trekking boots (broken in before the trip) are essential. Layer up for high-altitude cold (down jacket, thermal base layer, fleece, waterproof). The tour includes a hired down jacket and sleeping bag. Bring moisture-wicking socks, a sun hat, sunglasses, high-SPF sunscreen, and trekking poles (included in hire). A lightweight daypack is essential. Nepal uses Type C and D plugs at 230V.
Are any vaccinations required?
Recommended vaccinations for Nepal include Diphtheria, Hepatitis A, Tetanus, and Typhoid. Malaria risk is mainly low on this itinerary. Consult your GP or travel clinic.
Do I need to book international flights through you?
No. The trek starts and finishes in Kathmandu. Fly into Tribhuvan International Airport (KTM).
What about tipping?
Tips are expected and highly valued by guides and porters. Suggested ranges are: guide around an amount per person per day, assistant guide slightly less, porters less again. Your guide will brief you on current norms at the start of the trek.
How should I train for this trek?
Start training at least three months before departure. Focus on cardiovascular fitness (hiking with a loaded pack, stair climbing, long walks on consecutive days) and leg strength. Breaking in your trekking boots thoroughly is critical. A pre-trek test day hike of 6-8 hours is highly recommended.
Can I do the Everest Mountain Flight from Kathmandu?
Yes. An Everest Mountain Flight from Kathmandu gives you a spectacular close-up aerial view of Everest and the Himalayan range. Available as a paid optional extra.
Can I add a Panauti Homestay extension?
Yes. A Panauti Homestay cultural extension adds a night in a traditional Newari community near Kathmandu. Available as a paid add-on.
Can I add extra nights in Kathmandu?
Yes. Extra nights in Kathmandu before or after the trek can be added. Contact our sales team.
How far ahead should I book?
October and November departures fill well in advance. Book four to six months ahead for peak season.
How does booking work?
Book online via the Dates and Prices page. Pay a deposit or hold a reservation. Balance is due 8 weeks before departure.
Do I need travel insurance?
Yes, compulsory, and critically important on this trek. Insurance must cover helicopter evacuation from the maximum altitude of 4,610m. World Nomads covers trekking and helicopter evacuation at this altitude.
What is your cancellation policy?
A sliding scale of charges applies. Full terms are in our booking conditions. Trust My Travel financial protection covers your funds.
What if my dates are already sold out?
