The Kanchenjunga trek is hard because of its length and remoteness, not because it is technical. You walk for about three weeks, reach about 5,140 m, and spend many nights in camp. It suits strong walkers who have already trekked at altitude.
Length
Plan on long days and many of them. Even the north side alone is about two weeks of walking. Fatigue builds up, so fitness is not just about one hard day; it is about being able to repeat six or seven hours of walking day after day.
Altitude
The sleeping altitude rises slowly, with a rest day at Ghunsa, around 3,595 m. The last stage takes you to about 4,780 m at Lhonak and to about 5,140 m at Pangpema. Altitude sickness is a real risk above 4,000 m, so follow the usual rules: go up slowly, drink well and descend if symptoms worsen.
Remote conditions
Rescue is slow here. There are few clinics, no road above the lower villages and weather can stop helicopters. That is why we plan extra days, carry a medical kit and use guides who know the valley.
Terrain
Trails are narrow, rocky and steep in places, with long climbs and descents through the lower valleys and a final stretch over moraine. Bridges can be rough, and monsoon landslides sometimes change routes.
Fitness and experience
Build a base of hill walking or running for at least three months. Previous treks above 4,000 m help a lot. If you are unsure, ask us about your experience before you book.
How to train
Train for at least three months. Hike with a loaded pack, climb stairs, and do back-to-back long walking days on weekends. Build up to six or seven hours of hill walking, and practise in the boots and socks you will wear.
Warning signs to act on
Persistent headache, vomiting, unusual breathlessness at rest, confusion or loss of balance mean you should stop climbing and descend. Tell your guide at once. Do not wait for the morning, because symptoms often get worse overnight.
