Kanchenjunga Circuit Trek (North and South Base Camp)

No. The same USD 20-per-week restricted-area permit that covers the North Base Camp Trek also covers the full circuit to Oktang, South Base Camp, with no second application required, per the Kanchenjunga permit and restricted-area guide. Because this itinerary spends roughly three weekly periods inside the restricted zone rather than two, the permit line totals about USD 60 per person instead of USD 40, still the lightest restricted-area cost of any Nepal region by a wide margin.

The same two-trekker, licensed-guide minimum applies, filed once with a registered agency through the Department of Immigration in Kathmandu. Trekkers who book the North-only trip and later decide to add the south side need only an amended group filing, not a fresh application, since Immigration checks the group roster rather than a specific base camp destination.

A 2026 group departure runs USD 2,800 to 3,500 per person, roughly USD 500 to 600 above the North Base Camp Trek's USD 2,300 to 2,900 range for the same trip's core, plus four to six extra days of camping crew, food, and permit weeks. The connecting section between Lapsang La and Sinion La carries no lodge or resupply point, so the extra cost concentrates in that stretch: more food carried per trekker, and a slightly larger crew than the North-only trip needs to manage two base camps instead of one.

Compared with Manaslu Circuit's USD 1,500 to 2,100 group rate in the Nepal trek costs guide, the Kanchenjunga Circuit costs more for a genuinely different reason: Manaslu's price reflects its restricted permit and conservation fees on a teahouse-supported route, while Kanchenjunga's price reflects a much longer camping section with almost no lodge infrastructure at all past Ghunsa. A quote noticeably under USD 2,500 for this circuit is worth questioning closely, since the crew and food carried across the connecting passes are the one part of this itinerary with no shortcut.

From Ghunsa, the circuit climbs back past Kambachen toward a high camp below the Lapsang La (5,160 m), the trek's highest point, crossed on firm morning snow before the pass typically clouds over by mid-morning. The descent from Lapsang La leads to a second climb over the Sinion La (4,660 m) within the same push or the following day depending on group pace and weather, and this stretch, roughly four to five days from Ghunsa to the south-side village of Tseram, has no lodge, teahouse, or resupply point anywhere along it.

Every meal across this section is carried in by the camping crew from the moment the group leaves Ghunsa, the same no-resupply discipline used on the Upper Dolpo Circuit's Numa La-Baga La stretch, though Kanchenjunga's connecting section runs longer. Weather holds are the main planning risk here: a storm at either pass can add a full day to the crossing, which is why our itineraries build one spare day into this section rather than the tighter margin a shorter trek allows.

Oktang, South Base Camp, sits at approximately 4,730 m and looks directly onto Kanchenjunga's Yalung face, a completely different aspect of the mountain from Pangpema's view of the north wall, plus a clear line to Jannu (7,710 m), a peak barely visible from anywhere on the North-only itinerary. Reaching Oktang from Tseram is a shorter, gentler push than the approach to Pangpema, since the south side's base camp trail climbs less steeply over its final stretch.

The exit from the south side runs through Tortong and down to Yamphudin, a lower-altitude Limbu village that the North-only itinerary never passes through, before rejoining a jeep-accessible road back toward Taplejung. This means a circuit trekker sees meaningfully more of the region's cultural and geographic range, both faces of the mountain, two distinct approach valleys, and villages on both the Tamor and the southern watershed, than the North Base Camp Trek alone covers.

Strenuous is our grading, a step above the North Base Camp Trek alone: 195 km, roughly 9,600 m of cumulative ascent, and multiple nights above 4,500 m spread across both the Pangpema approach and the Lapsang La-Sinion La crossing. No single section is technical, but the extended high-altitude exposure, several days in a row above 4,000 m with two separate passes above 4,600 m, asks more of a trekker's acclimatization than either base camp alone.

Our itinerary holds acclimatization days at Ghunsa (3,595 m) and Kambachen (4,050 m) before the push to Pangpema, the same schedule as the North-only trip, and adds a rest day at Tseram (3,870 m) on the south side before the group descends toward Yamphudin, giving the body a lower-altitude buffer after the connecting-pass crossing rather than pushing straight down to the road. The Himalayan Rescue Association's 500-m-per-day sleeping-altitude guideline, covered in the altitude sickness prevention guide, governs every stage of this itinerary, and our guide runs twice-daily pulse-oximeter checks from Kambachen through the Tseram rest day. Because this circuit spends more consecutive days above 4,000 m than almost any other route we operate, a policy covering helicopter evacuation to at least 5,500 m, detailed in helicopter evacuation insurance coverage, is mandatory, not optional.

Late September through November gives the surest crossing conditions on both the Lapsang La and Sinion La, per the best season to trek Kanchenjunga guide, since Kanchenjunga carries no rain-shadow protection and both passes need firm, settled snow rather than the fresh, unstable cover an early-season or storm-affected window can leave. Late April into May is the second window, once lingering winter snow has had time to clear from both crossings; an earlier spring departure risks a pass closure that a North-only itinerary, with its single approach and no connecting crossing, doesn't carry.

We do not run this circuit during the June-to-September monsoon or the December-to-February winter closure, the same restrictions that apply to the North Base Camp Trek, but the stakes are higher on the full circuit specifically because a weather delay at either pass has no lower-altitude bailout route the way a single-approach trek does.

Booking timing matters more here than on the North-only trip: a spring departure needs confirmation by February to secure the crew and permit slots this longer itinerary requires, since the camping crew for the connecting-pass section is larger and harder to assemble on short notice than the North Base Camp Trek's staffing. Autumn departures should be confirmed by July for the same reason, ahead of the October-November peak window most groups target for the surest crossing conditions.

Start from the Nepal trekking packing list's four-season sleeping bag, rated to at least -15 C comfort, and the same layered clothing base every high route on this site requires. The connecting-pass section between Lapsang La and Sinion La runs colder and more exposed than either base camp approach alone, so pack an extra insulating layer and windproof shell beyond what the North Base Camp Trek alone needs, plus trekking poles for the longer sustained descents on both the north and south sides.

Because this circuit carries more consecutive high-altitude camping nights than most routes we operate, a closed-cell foam sleeping pad as backup to an inflatable mat is worth the extra weight; a punctured mat has no easy fix on the multi-day stretch between Ghunsa and Tseram.

An eight-person circuit group runs with seven to nine support staff across the full itinerary, one or two more than the North Base Camp Trek's six to eight, since the connecting-pass section needs enough hands to move camp faster than a single-approach trek requires. The extra crew member typically covers additional food-carrying capacity for the Lapsang La-Sinion La stretch rather than a specialist role, since no technical climbing skills apply anywhere on this route.

Local porters are hired in Taplejung and Ghunsa for the north-side approach and, where the itinerary allows, supplemented near Yamphudin for the return leg, the same local-hire pattern detailed on the sustainability page. This split hiring keeps costs from concentrating in one village's labor market and follows the porter-welfare approach we apply on every remote-region departure, camping-based or not.

Trekkers who've already completed a shorter restricted-area route, or who specifically want both faces of Kanchenjunga rather than a single approach, are the clearest fit for the full circuit. The extra four to six days and roughly USD 500 to 600 buy a genuinely different second half of the trip, not a repeat of the first: a different valley, a different village culture on the exit through Yamphudin, and a mountain aspect, the Yalung face, that the North-only itinerary never reveals.

Trekkers with a tighter schedule, a first restricted-area trek under their belt, or less certainty about multi-day high-altitude camping should start with the North Base Camp Trek instead; it reaches the same first close view of Kanchenjunga in six fewer days and without the connecting-pass section's no-resupply demands. Both itineraries run on the same permit and the same guide, so upgrading from one to the other on a future trip needs no new paperwork beyond an amended booking.
