Sitting astride the Nepal-India border, Kanchenjunga for the time being is still the domain of camping trekkers. That said, the lower approaches are seeing road and lodge development. There are two popular routes into the Kanchenjunga Peaks and mountains.
In general more popular option is to the North Base Camp and pang pema. It shows off the immense glaciers and towering ramparts of Kanchenjunga and Jannu to the most effect. The other option is via the Yalung glacier to the South Base Camp approach, close to the Sikkim border. Taking just a little extra time, the two base camps can be combined by crossing the Mirgin La (4665m)
Most approach the area from Suketar/Taplejung by rough dirt road or unreliable flight. Treks in the region are longer because of the greater distance from the trailheads to the peaks. Three weeks is an absolute minimum for a well-planned trek.
Hrading from Taplejung the north base camp trail crosses the middle hills and passes through Chirwa, Sakathum, Amjilosa and Gyabla to Ghunsa (3410m). This is a major village and resting point before the arduous route begins into the high country. From Ghunsa the route is all up via Khambachen for a rest day then Lhonak and on to Pang Pema (5400m).
The views of Kanchenjunga are said to be sublime from here. It takes around 6-7 days to return to Suketar airstrip via Ghunsa. Those heading across the demanding Mirgin La and satellite passes need to retreat to Ghunsa (2 days). From here the high trail takes 2 days to reach Tseram for the hike to the yalung Glacier viewpoints.
Those only doing the South Base Camp approach trek should allow 14-15 days if starting and ending in Taplejung/Suketar. The route heads via Tembawa, Khesewar, Mamake, Yamphudin, Amji Khopla, Torontan, Tseram and Ramche.
