Kanchenjunga Base Camp Trek (18 Days) — Kathmandu to Kathmandu, Nepal

Kanchenjunga Base Camp Trek — 18-Day Itinerary (Kathmandu to Kathmandu)

Route: Kathmandu — Suketar/Taplejung — Chirwa — Sekathum — Amjilassa — Gyabla — Ghunsa — Kambachen — Lhonak — Pangpema — Kambachen — Ghunsa — Sekathum — Taplejung — Kathmandu

Day 1: Arrive Kathmandu (1,400m) — Orientation & Permit Preparation

• Arrive at Tribhuvan International Airport (KTM) and private transfer to hotel in Thamel.
• Afternoon reserved for permit processing — your guide will coordinate the Restricted Area Permit (RAP), Kanchenjunga Conservation Area Permit (KCAP), and TIMS Card. Both permits must be in hand before the trek departs Taplejung; this is not a formality but a legal requirement for entry into the restricted zone.
• Evening trek briefing: 18-day route overview, altitude profile, acclimatisation strategy, the restricted area protocol, tea house and camp logistics, and what to expect on the high glacier sections above Kambachen.
• Optional walk around Thamel for last-minute gear or currency exchange.
• Overnight: Hotel Amaryllis or similar, Kathmandu
• Meals: Dinner

Day 2: Fly Kathmandu to Suketar / Taplejung (2,420m)

Flight: ~55 minutes to Suketar Airport

• Morning flight to Suketar Airport (2,420m) — the gateway to the Kanchenjunga region in Nepal's far east. The approach over the Himalayan foothills is spectacular; on clear mornings the Kanchenjunga massif itself is visible on the eastern horizon from the aircraft.
• Suketar sits on a ridge above the market town of Taplejung — a different Nepal entirely from Kathmandu. Eastern Nepal is less visited, culturally richer in Limbu and Rai heritage, and geographically distinct from both the Khumbu and the Annapurna regions. The pace of life is slower; the mountain that defines this landscape is, by any measure, one of the most extraordinary on earth.
• Afternoon walk through Taplejung to orientate, meet the full guide and porter team, and review the complete route. This is the last point at which gear adjustments or additional equipment can be sourced — Taplejung has limited but functional supply options.
• Overnight: Local lodge, Taplejung (2,420m)
• Meals: Breakfast, Dinner

Day 3: Trek Taplejung to Chirwa (1,270m)

Trek: ~14 km | 5–6 hours | Altitude loss: ~1,150m

• The trek descends steeply from Taplejung's ridge into the Tamor River valley through cardamom and banana plantations, terraced rice paddies, and the first Limbu villages of the route. The descent is rapid — from 2,420m to 1,270m in a single day — and the environment shifts dramatically from temperate ridge to warm subtropical valley floor.
• Mani walls, prayer flags, and traditional Limbu longhouses line the trail throughout. The Tamor River below is one of the major tributaries of the Koshi system and carries turquoise snowmelt even at this low elevation. This section has the character of rural eastern Nepal at its most authentic — a world that bears no resemblance to the trekking infrastructure of Namche or Pokhara.
• Chirwa (1,270m) is a large Limbu market village at the valley floor, well-established as a tea house stop for the small volume of Kanchenjunga trekking traffic that passes through.
• Overnight: Tea house, Chirwa (1,270m)
• Meals: Breakfast, Lunch, Dinner

Day 4: Trek Chirwa to Sekathum (1,660m)

Trek: ~12 km | 5–6 hours

• The route follows the Tamor River upstream through a narrowing valley, crossing suspension bridges and passing through the settlement of Yamphudin and smaller Rai communities where the trekking population thins further. This is a journey deeper into a Nepal that most visitors never reach.
• Sekathum (1,660m) marks the confluence of the Ghunsa Khola and the Tamor River — a significant trail junction. From here the route turns due north and begins its serious sustained climb toward the high Himalaya. The Ghunsa Khola will be the companion for the next four days of ascent, growing from a wide lowland river to a glacial torrent above 3,500m.
• Overnight: Tea house, Sekathum (1,660m)
• Meals: Breakfast, Lunch, Dinner

Day 5: Trek Sekathum to Amjilassa (2,490m)

Trek: ~13 km | 6–7 hours | Altitude gain: ~830m

• The trail climbs steadily alongside the Ghunsa Khola through increasingly dense forest — oak, maple, and the first rhododendron stands that will dominate the mid-altitude sections of the route. In spring (April), these rhododendron forests are among the finest in Nepal: multiple species in simultaneous bloom, the forest floor covered in fallen petals, the canopy red and pink above the trail.
• The valley narrows progressively as altitude is gained. Settlement becomes sparse. The sound of the river below is constant; occasional waterfalls drop from the cliffs above. This is the heart of the lower Kanchenjunga approach — unhurried, forested, and deeply peaceful.
• Amjilassa (2,490m) is a small tea house settlement in a forest clearing — remote, quiet, and the last reliable resupply point before Ghunsa three days ahead.
• Overnight: Tea house, Amjilassa (2,490m)
• Meals: Breakfast, Lunch, Dinner

Day 6: Trek Amjilassa to Gyabla (2,730m)

Trek: ~10 km | 4–5 hours | Altitude gain: ~240m

• A shorter day through dense rhododendron and birch forest as the valley character begins to change. Prayer flags appear more frequently; the stone architecture of the scattered settlements takes on a more Tibetan character; the vegetation shifts from subtropical to sub-alpine. Below the trail, the Ghunsa Khola narrows and quickens.
• At Gyabla (2,730m) — a small cluster of tea houses beside a yak pasture — the first clear indications of the Tibetan cultural world that will define the upper valley appear. Stone walls carved with Om Mani Padme Hum, a small chorten at the trail head, and the first yak herders encountered on the route. The temperature at camp in the evening is noticeably cooler than the valley below.
• Overnight: Tea house, Gyabla (2,730m)
• Meals: Breakfast, Lunch, Dinner

Day 7: Trek Gyabla to Ghunsa (3,595m)

Trek: ~11 km | 5–6 hours | Altitude gain: ~865m

• The forest clears above Gyabla and the valley opens into high pasture. For the first time, significant sections of the Kanchenjunga range become visible above the ridgeline ahead — the scale of the massif, even at this distance, is genuinely arresting. The altitude gain on this day is the most significant since Taplejung; the pace slows and the mountain air thins.
• Ghunsa (3,595m) is the most significant settlement in the upper valley — a permanent Tibetan Buddhist community with stone-built houses, a working gompa, a small cheese factory, and yak herds grazing the surrounding plateaus. It is one of the most isolated year-round villages in all of eastern Nepal, and it has the particular atmosphere of a place that exists entirely on its own terms. This is the acclimatisation base for the approach to Pangpema.
• Overnight: Tea house, Ghunsa (3,595m)
• Meals: Breakfast, Lunch, Dinner

Day 8: Acclimatisation Day at Ghunsa — Hike to Rampuk Kharka (4,200m)

Acclimatisation hike: ~8 km return | 3–4 hours

• A mandatory rest and acclimatisation day before entering the high glacier zone above 4,000m. The body has climbed from 1,270m at Chirwa to 3,595m at Ghunsa in five days — a meaningful altitude gain that requires consolidation before proceeding further.
• Morning: Visit the Ghunsa gompa — a working monastery with wall murals, butter lamps, and prayer rooms that are open to respectful visitors. The head lama, if present, may be willing to offer a brief blessing for the journey ahead. Allow an unhurried hour here; this is one of the most authentic religious communities accessible from any major Nepal trekking route.
• Afternoon: Acclimatisation hike to Rampuk Kharka (4,200m), a yak pasture with early views toward Kanchenjunga's west face and the glacial terrain above. Follow the "climb high, sleep low" protocol: ascend to 4,200m, assess how the body responds, and descend to sleep at Ghunsa. Blood-oxygen readings taken and recorded at the high point.
• Overnight: Tea house, Ghunsa (3,595m)
• Meals: Breakfast, Lunch, Dinner

Day 9: Trek Ghunsa to Kambachen (4,050m)

Trek: ~10 km | 5–6 hours | Altitude gain: ~455m

• The trail leaves Ghunsa and climbs through the upper valley past yak herding summer pastures. The terrain becomes increasingly rocky and alpine — glacial moraines appear on the valley walls, the Ghunsa Khola narrows to a boulder-choked torrent, and the air thins perceptibly with every hour of ascent.
• Above the treeline entirely, the landscape is vast and open in a way that is qualitatively different from the forest sections below. The sense of remoteness deepens: there are no villages ahead until the return, no settlements, no facilities beyond what the small tea house at Kambachen provides.
• Kambachen (4,050m) sits beneath the south face of Jannu (7,711m) — one of the most dramatic and technically imposing mountain walls visible from any trekking route in Nepal. The peak rises almost vertically from the valley to its summit in a single sweep of ice and granite. It is worth arriving at Kambachen with enough time and energy to simply sit and look at Jannu before dark.
• Overnight: Tea house, Kambachen (4,050m)
• Meals: Breakfast, Lunch, Dinner

Day 10: Trek Kambachen to Lhonak (4,780m)

Trek: ~9 km | 5–6 hours | Altitude gain: ~730m

• Above Kambachen the valley narrows into a true glacial corridor. The trail traverses moraine ridges along the edge of active glacier systems, with the Kanchenjunga massif growing steadily larger ahead. The five summits — now clearly distinguishable — fill the northern skyline as the day progresses. The environment is cold, wind-exposed, and utterly remote.
• This is the most altitude-demanding day of the ascent — 730m gained to a camp at 4,780m with the body already operating at significant altitude. The pace is slow and deliberate from Kambachen. Hydration, warm clothing, and an early arrival at camp are the priorities.
• Lhonak (4,780m) is a wind-exposed wilderness camp at the glacier edge — the most basic overnight on the entire route. Facilities are minimal: a small stone shelter or expedition tents. This is high-altitude wilderness accommodation in the truest sense. An early dinner, warm sleeping bag, and an early night are non-negotiable.
• Overnight: Tea house / camp, Lhonak (4,780m)
• Meals: Breakfast, Lunch, Dinner

Day 11: Trek to Pangpema — Kanchenjunga North Base Camp (5,143m)

Trek: ~6 km | 4–5 hours | Altitude gain: ~363m

• The final approach to Pangpema crosses the Lhonak glacier moraine on a route that requires careful footing on rocky, uneven terrain — slow and deliberate at 5,000m. The trail climbs progressively to the North Base Camp at 5,143m — the highest point on the route and the viewpoint for which 10 days of walking exist.
• Pangpema (5,143m) sits directly beneath the Yamatari Glacier with an unobstructed panorama of the complete Kanchenjunga massif: Kanchenjunga Main (8,586m), Kanchenjunga West (8,505m), Kanchenjunga Central (8,482m), Kanchenjunga South (8,476m), and Yalung Kang (8,505m) — five summits above 8,400m visible simultaneously across the glacier basin. Fewer than a thousand trekkers stand here in a full year. The scale, silence, and remoteness of Pangpema are difficult to convey in any medium other than standing in the place itself.
• Arrive, eat, rest. The altitude demands respect — move slowly, eat well, drink constantly, and report any symptoms immediately to your guide.
• Overnight: Tea house / camp, Pangpema (5,143m)
• Meals: Breakfast, Lunch, Dinner

Day 12: Rest and Exploration at Pangpema

• A full day at Kanchenjunga North Base Camp — to recover from the altitude, explore the immediate glacier margins, and experience the surroundings without time pressure. The morning light on the massif before 9:00am is the finest photographic opportunity on the entire route; the alpenglow sequence as the summits catch the first sun is one of the most extraordinary experiences in Himalayan trekking.
• Optional extension for fit trekkers: hike above Pangpema to a higher moraine ridge at approximately 5,400m for broader views north toward the Tibetan plateau and the Kanchenjunga glacier system. This hike is entirely non-technical but demanding at altitude — the guide will assess individual readiness on the morning and advise accordingly.
• Afternoon free at base camp. Many trekkers find this the most contemplative and satisfying day of the journey — the summit achieved, the pressure lifted, and nothing required except presence.
• Overnight: Tea house / camp, Pangpema (5,143m)
• Meals: Breakfast, Lunch, Dinner

Day 13: Trek Pangpema to Kambachen (4,050m)

Trek: ~15 km | 6–7 hours | Altitude loss: ~1,093m

• The descent from Pangpema begins the long return journey. The altitude drop from 5,143m to 4,050m brings immediate physical relief — breathing deepens, energy returns, and the landscape that appeared so austere on the ascent reveals new detail on the way down.
• The trail retraces the ascent route through Lhonak and back across the glacier moraine to Kambachen. Jannu's south face commands attention throughout the descent, its scale arguably more impressive on the return than on the approach. Arrive at Kambachen in time for a hot meal before dark.
• Overnight: Tea house, Kambachen (4,050m)
• Meals: Breakfast, Lunch, Dinner

Day 14: Trek Kambachen to Ghunsa (3,595m)

Trek: ~10 km | 4–5 hours

• Return to Ghunsa through the upper valley pastures. The familiar scale of the village after the exposed high glacier zone feels genuinely welcoming — stone houses, smoke rising from the gompa, yaks on the surrounding meadows. The descent through the alpine terrain above the treeline is easier in the legs than the ascent but requires continued care on moraine and rocky sections.
• Ghunsa's tea houses offer the best meal quality on the upper route — use the evening to eat well, dry equipment, and rest properly. A hot shower, where available, is one of the small luxuries of the return to Ghunsa.
• Overnight: Tea house, Ghunsa (3,595m)
• Meals: Breakfast, Lunch, Dinner

Day 15: Trek Ghunsa to Sekathum (1,660m)

Trek: ~22 km | 7–8 hours | Altitude loss: ~1,935m

• The longest day of the entire trek and the most demanding on the knees — a sustained descent of nearly 2,000m through Gyabla, Amjilassa, and the full rhododendron forest section back to Sekathum (1,660m) at the valley floor. Trekking poles are essential; the pace on the steeper descent sections through the forest should be controlled and deliberate.
• The environmental transition on this day is one of the most dramatic on the route — from the cold, open, treeless terrain above Ghunsa back through the birch and rhododendron belt (in spring, still in bloom on the return) to the warm, forested lower valley. Birdsong returns. The air thickens. The subtropical world reasserts itself by mid-afternoon.
• Overnight: Tea house, Sekathum (1,660m)
• Meals: Breakfast, Lunch, Dinner

Day 16: Trek Sekathum to Taplejung / Suketar (2,420m)

Trek: ~16 km | 6–7 hours | Altitude gain: ~760m

• The final trekking day. The trail follows the Tamor River downstream through Chirwa before climbing back up the ridge through cardamom plantations and Limbu villages to Taplejung (2,420m). The full arc of the journey — from the subtropical Tamor valley at 1,270m to the glacier world at 5,143m and back — is visible in retrospect with the end in sight.
• Arrive Taplejung in the afternoon. Final group dinner with guide and full porter team — tips are customary, genuinely meaningful, and reflect the logistical complexity and physical demand of running a 16-day restricted area trek in eastern Nepal.
• Overnight: Local lodge, Taplejung (2,420m)
• Meals: Breakfast, Lunch, Dinner

Day 17: Fly Suketar to Kathmandu — Overnight Kathmandu

Flight: ~55 minutes from Suketar Airport

• Morning flight from Suketar Airport back to Kathmandu. Suketar flights are weather-dependent and morning-only — afternoon winds consistently prevent operations. If the morning flight is cancelled due to weather, this day absorbs the delay. International onward flights should not be booked before Day 18. Trekkers with tight connections should discuss this explicitly with Summit Routes before booking.
• Transfer to hotel on arrival. Rest afternoon — hot shower, laundry, and the considerable pleasure of being back at 1,400m after 17 days. The contrast between Pangpema and a Kathmandu hotel room is not easily bridged in a single afternoon, but the attempt is worthwhile.
• Overnight: Hotel Amaryllis or similar, Kathmandu
• Meals: Breakfast, Dinner

Day 18: Departure from Kathmandu

• After breakfast, private transfer to Tribhuvan International Airport (KTM) for onward departure.
• Meals: Breakfast
