Gosaikunda Lake Trek

• The Sacred Lakes of Gosaikunda (4,380 m): Reach a chain of high alpine lakes revered by Hindus and Buddhists alike, set in a bare rocky basin.

• Sing Gompa and the Cheese Factory: Stay at a monastery settlement in the forest that has produced yak cheese for decades.

• Langtang and Ganesh Himal Views: Take in Langtang Lirung, Ganesh Himal, and the Tibetan border ranges from the ridge above the lakes.

• Rhododendron and Oak Forest: Climb through dense middle-hill forest rich in birdlife and, in spring, full of flowering rhododendron.

• High Altitude in Seven Days: Reach 4,380 m and return to Kathmandu inside a week with only three walking days.

March to May and October to November are the two main seasons. Spring brings flowering rhododendron on the climb from Dhunche and reliable weather at the lakes. Autumn gives the clearest views across to Langtang Lirung and Ganesh Himal and the most settled conditions on the exposed shelf above Sing Gompa.

Winter brings heavy snow to the lake basin and the trail above Sing Gompa is frequently impassable between January and March, with the lakes themselves frozen. The monsoon is generally poor for views, but it is worth knowing that August brings the Janai Purnima pilgrimage, when thousands of devotees walk to the lakes — an extraordinary spectacle, if you are willing to accept rain and cloud in exchange.

For a month-by-month look at weather and trail conditions, see our guide to the best time to trek in Nepal.

This is a short trek that reaches a genuinely high altitude, and the profile deserves respect. You sleep at 1,950 m in Dhunche, 3,330 m at Sing Gompa, and 4,380 m at Gosaikunda on consecutive nights — a gain of well over 1,000 m on each of the two climbing days, which is faster than the usual guidance.

Mild headache and disturbed sleep at Gosaikunda are common as a result. Your guide will set a deliberately slow pace on the climb from Sing Gompa and will check the group carefully on arrival at the lakes. Drink at least three litres of water a day from the first day, avoid alcohol entirely, and report symptoms early — the descent from Gosaikunda back toward Dhunche is quick and resolves altitude illness reliably. If you have time, adding an extra night at Sing Gompa makes this trek significantly more comfortable, and we are happy to build it in.

Prevention, symptoms and treatment are covered in depth in our guide to altitude sickness in Nepal.

Travel insurance covering trekking to at least 5,000 m is required, giving a safe margin over the Gosaikunda lakes at 4,380 m. Standard policies often cap at 3,000 m, which would leave you uninsured for the highest and most exposed part of the route, so check the altitude clause specifically before you buy.

The policy must include emergency helicopter evacuation and medical treatment. Above Sing Gompa there is no road access and the altitude gain on this short itinerary makes altitude illness more likely than on a longer route, so evacuation cover is not a formality here. Send us your policy number and the insurer's 24-hour emergency contact before you leave Kathmandu.

Our guide to travel insurance for trekking in Nepal explains the altitude limits, evacuation terms and common exclusions to check before you buy.

The lake basin is exposed, windy, and much colder than the forest below. Bring waterproof trekking boots, three base layers, a fleece, an insulated down jacket, a windproof and waterproof shell jacket and trousers, trekking trousers, a warm hat, sun hat, gloves, and wool socks. A sleeping bag rated to -10°C is right for the Gosaikunda lodge, which is unheated at night.

Also pack a 30-litre daypack, trekking poles for the steep descent back to Dhunche, a headlamp with spare batteries, high-SPF sunscreen and lip balm, sunglasses for the glare off snow and water, a reusable bottle with purification tablets or a filter, a small first aid kit with blister care, a quick-dry towel, toiletries, and a power bank, since charging at the lakes is solar-only and limited.

For the complete kit list, organised by the altitude you will reach, see our Nepal trekking packing list.

You stay in a tourist-standard hotel in Kathmandu and in teahouses at Dhunche, Sing Gompa, and Gosaikunda. Dhunche and Sing Gompa have reasonable lodges with twin rooms, blankets, and warm dining rooms. The lodges at Gosaikunda are the most basic on the route — simple rooms, shared toilets, no heating outside the dining room, and limited water — and they fill quickly during festival periods.

Three meals a day are included on the trek. Menus are short: dal bhat with free refills, noodle soup, fried rice, eggs, chapati, potatoes, and porridge. Sing Gompa is worth stopping at for its locally made yak cheese, which appears on the menu in various forms. Everything at the lakes is carried up on foot, so prices rise and choice narrows. Refill your bottle at the lodges and treat it with tablets, a filter, or a UV pen; the lake water itself is sacred and should not be used for washing or drinking.

What the lodges are really like, from rooms and meals to showers and charging, is covered in our guide to teahouse trekking in Nepal.
