In the far east of Nepal, on the border with Sikkim, rises Kanchenjunga (8,586 m), the third-highest mountain in the world. Its name means "Five Treasures of the Snow", after its five great summits, and for the Limbu and Sikkimese people it is a sacred guardian deity. The Kanchenjunga Base Camp trek explores the remote valleys around its western and southern sides, reaching both the north base camp at Pangpema (about 5,140 m) and the south base camp near Oktang (about 4,730 m).
It is one of the longest and wildest teahouse treks in Nepal, and one of the least visited. For experienced trekkers who want to get away from the crowds, it has old forest, glaciers, remote Limbu and Sherpa villages, and the third-highest mountain in the world. Below: the routes, permits, difficulty and how to plan it.
Quick answer: the Kanchenjunga Base Camp trek takes about 20–24 days from Kathmandu, visiting Pangpema (north base camp, about 5,140 m) and Oktang (south base camp viewpoint, about 4,730 m), linked by the Sele La and Mirgin La passes. It requires a restricted area permit, the Kanchenjunga Conservation Area Permit, a licensed guide and at least two trekkers. It is graded challenging, best in October–November and April–May, and costs about US$2,300–3,200 with a guide and porters.

Why trek to Kanchenjunga?
- Solitude: only a few thousand trekkers a year, compared with tens of thousands on the Everest trail.
- Two base camps of the world's third-highest mountain.
- Wild landscapes: dense forests, the Kanchenjunga and Yalung glaciers, high pastures and lakes.
- Culture: Limbu, Rai, Sherpa and Tibetan-influenced communities.
- Wildlife: the Kanchenjunga Conservation Area is home to red pandas, snow leopards, blue sheep and many birds.
Routes: north, south or the full circuit
There are three main options:
- North base camp only (about 18–20 days): up the Tamor and Ghunsa valleys to Kambachen, Lhonak and Pangpema, returning the same way.
- South base camp only (about 14–16 days): via the Yalung valley to Tseram, Ramche and Oktang.
- Full circuit (about 20–24 days): combining both base camps by crossing the Sele La, Sinion La and Mirgin La passes between Ghunsa and Tseram. If you have the time, this is the route to do, and most people do.

Highlights along the way
Ghunsa
Ghunsa is the main village in the upper valley, a Sherpa and Tibetan-influenced settlement of wooden houses, prayer flags and a small monastery. It is the natural acclimatisation stop before heading higher.
Kambachen and Lhonak
Above Ghunsa, the valley opens into high pastures at Kambachen, beneath the huge north face of Jannu (Kumbhakarna, 7,710 m). Further up, Lhonak is a stark, rocky plain beside the Kanchenjunga Glacier.
Pangpema: north base camp
From Lhonak, the trail follows the glacier moraine to Pangpema, where the enormous north face of Kanchenjunga fills the view. Few viewpoints in Nepal put you this close to so much ice.
The passes
The crossing from Ghunsa to Tseram over the Sele La, Sinion La and Mirgin La is a long, high day with panoramic views, possibly including Makalu and Everest in the far distance on clear days.
Oktang: south base camp
From Tseram and Ramche, a walk along the Yalung Glacier leads to the Oktang viewpoint, with the south face of Kanchenjunga rising above an amphitheatre of ice.
Permits
The Kanchenjunga region is a restricted area. You need a Kanchenjunga Restricted Area Permit, charged per week (about US$20 per week for the first four weeks at the time of writing), and the Kanchenjunga Conservation Area Permit (about NPR 3,000). Permits require at least two trekkers and a licensed guide through a registered agency. We cover this in our permits guide.
Difficulty
The Kanchenjunga trek is challenging. It is long, with many consecutive days of walking and big altitude gains and losses as the trail climbs in and out of valleys. The passes and base camps are high and remote. Lodges are basic, and some sections have few facilities. It is best suited to trekkers with previous high-altitude experience, such as Everest Base Camp or the Annapurna Circuit, and good fitness. Our training guide goes into more detail.
Accommodation and food
Teahouses now operate along most of the route, making Kanchenjunga a teahouse trek, although lodges are simpler than in the Everest or Annapurna regions and may be crowded in peak season. Some lodges at high points such as Lhonak, Pangpema and Sele Le are very basic, and some trekkers still camp. Food is simple: dal bhat, noodles, potatoes, Tibetan bread and eggs. Bring snacks and supplementary food from Kathmandu.
Best time
The trek is best in October–November, with clear skies and stable weather, and April–May, when rhododendrons bloom in the lower forests. Winter brings snow to the passes and very cold nights; the monsoon brings heavy rain, leeches and landslides to this very wet eastern region.
The journey, day by day
The adventure begins with a flight from Kathmandu east to Bhadrapur or Biratnagar in the lowlands, followed by a long drive north through tea gardens and terraced hills to Taplejung, the district headquarters. Newer roads now continue further up the Tamor valley, so the walking may start at villages such as Sekathum or Amjilosa, depending on road conditions and the season. The first days follow the Tamor River and then the Ghunsa Khola through thick subtropical and temperate forest, crossing suspension bridges, passing waterfalls and small villages of Limbu and Rai farmers who grow cardamom, millet and maize on the steep slopes.
As you climb, the forest changes to rhododendron, oak and fir, and the villages become Sherpa and Tibetan in character, with prayer flags and small gompas. Gyabla and Phale, the latter a former Tibetan refugee settlement, lead to Ghunsa, where you rest and acclimatise. Above Ghunsa, the trail crosses a landslide area and climbs to Kambachen, right under the enormous north face of Jannu. Another day brings you to Lhonak, a stark plain of glacial moraine surrounded by peaks, and from there, the final walk along the Kanchenjunga Glacier to Pangpema. Standing at the north base camp, facing the vast walls of Kanchenjunga, is the high point of the journey.
After returning to Ghunsa, the circuit crosses the high passes to the south side. It is a long, high day across three passes, with sweeping views of the eastern Himalaya, before descending to Tseram in the Simbua Khola valley. From there, you walk up the Yalung Glacier to Ramche and the Oktang viewpoint, where Kanchenjunga's south face and the peaks of the Sikkim border close in around you. The descent through dense forest via Torongding, Yamphudin and Limbu villages completes the circuit.
Wildlife and nature of the Kanchenjunga Conservation Area
The Kanchenjunga Conservation Area protects one of the richest mountain ecosystems in Nepal. Its forests of rhododendron (the region has dozens of species), oak, magnolia, fir and birch are home to red pandas, Himalayan black bears, musk deer and many bird species. Above the tree line, blue sheep (bharal) graze on the high pastures, and snow leopards hunt, although they are rarely seen. The area is managed with the participation of local communities, who benefit from tourism and conservation programmes. In spring the lower valleys are full of flowering rhododendron; autumn gives the clearest views of the peaks.
Culture of the Kanchenjunga region
The lower valleys are home to Limbu and Rai communities, indigenous peoples of eastern Nepal with their own languages, the Kirat religion that honours nature and ancestors, and distinctive traditions such as the chyabrung drum dance. The Limbu consider Kanchenjunga a sacred deity. Higher up, Sherpa and Tibetan-influenced communities practise Tibetan Buddhism, with monasteries in Ghunsa and other villages. Few tourists pass through these villages, and people are curious about you. Try tongba, the warm millet beer of eastern Nepal, sipped through a bamboo straw.
Acclimatisation and safety
With nights above 4,000 m and base camps above 4,700 m and 5,100 m, proper acclimatisation is essential. Our itinerary includes rest days in Ghunsa and Kambachen, and the circuit's gradual approach helps. The high pass crossing between Ghunsa and Tseram is long and exposed, and can be snowy in late autumn and spring; it should only be attempted in good weather with an experienced guide. Because the region is remote, evacuation by helicopter is the main option in emergencies, and your insurance must cover trekking to at least 5,500 m and helicopter rescue. Read our altitude guide and insurance guide.

Packing for Kanchenjunga
Pack as for any high Himalayan trek, with extra attention to warmth and self-sufficiency. You need a sleeping bag rated to −15°C or colder, a warm down jacket, layers, waterproofs, broken-in boots, gaiters and microspikes for the passes, a headlamp, water purification, a comprehensive first-aid kit and extra snacks. Leeches are common in the lower forests in spring and the monsoon, so bring leech socks. See our packing list.
Who should trek to Kanchenjunga?
The Kanchenjunga trek suits experienced trekkers looking for a true wilderness adventure, with the time and fitness for three weeks on the trail and a tolerance for simple lodges and long days. It rewards those who value solitude, pristine nature and unusual cultures over comfort. If you have done Everest Base Camp or the Annapurna Circuit and want something wilder, this is one of the finest treks in Nepal. For first-time trekkers, we recommend starting with a shorter, more developed route.
Getting to the trailhead
Reaching the start of the Kanchenjunga trek is an adventure in itself. Most trekkers fly from Kathmandu to Bhadrapur (Chandragadhi), a small airport in the south-eastern Terai near the Indian border, a flight of about 45 minutes with views of the eastern Himalaya on clear days. From Bhadrapur, a long drive of eight to ten hours climbs through the tea gardens of Ilam and the hills of Panchthar to Taplejung. An alternative is to fly to Biratnagar and drive via Dharan and Dhankuta. Occasionally, flights operate to Suketar airstrip above Taplejung, saving a long drive, but they are infrequent and weather-dependent. From Taplejung, jeeps continue up the valley as far as the road allows. Your trekking company will arrange the transport and advise on the best route based on current road conditions.
Lodges and life on the trail
Kanchenjunga's teahouses are simple family lodges, often built of stone and wood, with twin rooms, shared toilets and a smoky kitchen where the family cooks on a wood fire. In the evenings, trekkers gather around the stove with the lodge family, guides and porters, sharing stories over dal bhat and tea. Because few trekkers visit, you are often the only guests, and the welcome is warm and personal. Hot showers are rare higher up, charging is limited, and Wi-Fi is scarce or absent above Ghunsa, so the trek is also an opportunity to disconnect. Carry cash, as there are no ATMs beyond Taplejung.
Environmental and cultural responsibility
The Kanchenjunga region's remoteness has helped preserve its forests and wildlife, but it also means waste management and supplies are limited. Carry out all non-biodegradable waste, including plastic and batteries, use water purification rather than bottled water, and support local lodges and guides. Respect sacred sites, including the mountain itself, which the Limbu revere as a deity; never climb on chortens or remove stones from mani walls. Your visit, done responsibly, brings valuable income to communities that see few visitors.
A brief climbing history
Kanchenjunga was long thought to be the highest mountain in the world, until surveys in the mid-19th century confirmed that Everest was higher. It was first climbed on 25 May 1955 by Joe Brown and George Band of a British expedition led by Charles Evans. Out of respect for the beliefs of the Sikkimese people, who consider the summit sacred, they stopped a few metres short of the true top, a tradition that most climbers have followed since. The mountain remains one of the most dangerous of the 8,000 m peaks, with fewer ascents than Everest. Trekking to its base camps lets you appreciate its enormous scale without the risks of climbing.
Food and supplies
Food on the Kanchenjunga trek is simpler than on the popular trails, and menus become shorter as you climb. Expect dal bhat, noodle soup, fried rice, potatoes, eggs, Tibetan bread and porridge. Fresh vegetables are limited higher up, and prices rise because everything is carried in by porters or animals. Bring energy bars, nuts, dried fruit, chocolate and electrolyte tablets from Kathmandu to supplement your diet. Most lodges can boil water for purification; carry tablets or a filter. On a long trek like this, eating well is essential to maintain energy, so keep eating even when your appetite drops at altitude.
Photography on the Kanchenjunga trek
Photographers should aim for the vertical north face of Jannu at Kambachen, the vast glacier and north face of Kanchenjunga at Pangpema, sunrise over the eastern Himalaya from the passes, and the south face at Oktang. The lower valleys have thick forest, waterfalls and village life. Bring a wide-angle lens for the huge landscapes and a telephoto for distant peaks, plenty of batteries (charging is limited) and a way to keep them warm at night. Always ask permission before photographing people and religious sites.
Common questions from trekkers
Is the Kanchenjunga trek suitable for my first Himalayan trek? We generally recommend it for trekkers with previous high-altitude experience, because of its length, remoteness and simple facilities. Can I do only one base camp? Yes; the north base camp route is the most popular single option, while the south base camp route is shorter. Is there mobile coverage? Coverage exists in lower villages and sometimes in Ghunsa, but is unreliable higher up; your guide may carry a satellite phone or use local networks where available. How many trekkers go each year? Only a small fraction of the numbers on the Everest and Annapurna trails, which is a big part of its appeal. Can I extend to Sikkim? No, the border with Sikkim is closed to trekkers; the trek returns within Nepal.
Cost
Because of its length, flights to the east and restricted-area permits, Kanchenjunga is one of the more expensive teahouse treks. A guided trek typically costs US$2,300–3,200 per person including domestic flights, transport, permits, guide, porters, lodges and meals.
Guides and porters for Kanchenjunga
A licensed guide is compulsory in the Kanchenjunga restricted area, and on a trek this remote, their experience is invaluable. Choose a guide who has walked the full circuit, knows the conditions on the passes and has relationships with lodge owners along the route. Porters are usually hired from the region and know the trails intimately. On a long trek like this, porter welfare is especially important: make sure your company provides warm clothing, proper footwear, insurance and fair loads for its porters. Take a look at our guide to hiring a guide and porter.
Training for the Kanchenjunga trek
Train for at least three to four months, with a focus on endurance: long hikes with a pack, ideally on consecutive days, stair climbing, cardio and leg strength. The trek involves many days of steep ascents and descents, so strong knees and good stamina are essential. For the details, read our training plan.
Booking and planning timeline
Book the Kanchenjunga trek at least two to three months in advance, especially for October–November. Restricted area permits require your passport details, a minimum of two trekkers and processing in Kathmandu, so plan to arrive at least two days before the trek begins. Domestic flights to the east should be booked early, and you should keep one or two spare days at the end of your trip for weather or road delays.
Money matters
There are no ATMs beyond Taplejung, so bring enough Nepali rupees for the entire trek, including extras, snacks, charging and tips. Lodges accept only cash, and small notes are useful in remote villages.
Weather on the trek
Eastern Nepal receives more rain than the west, and weather can change quickly. Expect afternoon cloud even in the dry seasons, and be prepared for snow on the passes in late autumn and spring.
One practical point our guides always raise: the flights and drives to reach the trailhead in the far east take time, and weather can delay the Taplejung (Suketar) flight for a day or more. Build at least one spare day into both ends of the trip, and keep your international flight home flexible if you can.
Is Kanchenjunga right for you?
The Kanchenjunga Base Camp trek is one of the greatest wilderness journeys in the Himalaya. It asks a lot: three weeks of walking, simple lodges and high passes. In return, it gives you the world's third-highest mountain from two sides, pristine forests, rare wildlife and the warmth of communities that see few outsiders. For experienced trekkers who want something really remote, it's hard to beat. Contact us to plan your Kanchenjunga adventure.
