Kanchenjunga health and safety: altitude on the north trek and climbing risks

2 min readUpdated 2 Nov 2026By the Base Camp Hikes trek team

The short version: three of the most asked questions, answered in a line each. The rest of the page goes into detail.

  • How high do I sleep on the Kanchenjunga north route? Ghunsa is about 3,595 m, Khambachen about 4,050 m, Lhonak about 4,780 m and Pangpema about 5,140 m.
  • Which symptoms mean I should turn back or descend? A worsening headache, vomiting, confusion, unsteady walking or breathlessness at rest mean you should stop climbing and descend.
  • How should I prepare for the cold last days to Pangpema? The last days are high and cold, so pack a proper down jacket, warm sleeping bag, hat and gloves.

How high do I sleep on the Kanchenjunga north route?

Ghunsa is about 3,595 m, Khambachen about 4,050 m, Lhonak about 4,780 m and Pangpema about 5,140 m. The rise from Khambachen to Lhonak is the steepest, so ask your operator how the schedule handles acclimatisation. Add spare days if you can.

Which symptoms mean I should turn back or descend?

A worsening headache, vomiting, confusion, unsteady walking or breathlessness at rest mean you should stop climbing and descend. Mild symptoms can ease with rest at the same height. Tell your guide early, because the trek is long and help is far away.

How should I prepare for the cold last days to Pangpema?

The last days are high and cold, so pack a proper down jacket, warm sleeping bag, hat and gloves. Start early, keep snacks and water within reach and stay with your group. If the weather turns, follow your guide's decision to wait or descend.

How remote is medical help on the Kanchenjunga trek?

Very remote. The north trek is long, with basic lodges, camping at times and few supplies. Carry a good first-aid kit, take a guide trained in first aid, and ask your operator about evacuation plans and communication before you go.

What insurance should I take?

Choose a policy that covers trekking to at least 5,140 m and helicopter evacuation. Climbers need cover for the altitude they plan to reach. Check the exclusions and ask your operator what documents they require before departure.

Is the monsoon or winter safe for the trek?

Both bring risks. The monsoon brings rain, leeches and landslides, and snow can block the high trail in winter. Spring and autumn are the usual seasons. If you have a flexible schedule, ask your operator about conditions before choosing your dates.

What are the main dangers for climbers on Kanchenjunga?

Avalanches, crevasses, rockfall and altitude illness are all real risks, and records show it has been among the more dangerous 8,000 m peaks. Figures vary by source, so no rate is given here. Trekkers on the base camp routes do not face these technical hazards.
