Jannu and Kabru trek health and safety: altitude, cold and remote help

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 does the trail to Jannu views go? The route climbs steadily and reaches high, cold places.
  • How should I acclimatise on the north Kanchenjunga trail? Sleep lower than the highest point you reached in the day where possible, take rest days when advised and rise gradually.
  • What altitude symptoms mean I should go down? A headache that keeps getting worse, repeated vomiting, unsteady walking, confusion or breathlessness at rest are serious signs.

How high does the trail to Jannu views go?

The route climbs steadily and reaches high, cold places. Ghunsa is at about 3,595 m, and the trail continues up the valley to Khambachen, Lhonak and Pangpema. Ask your operator for the sleeping heights of your itinerary and take acclimatisation seriously.

How should I acclimatise on the north Kanchenjunga trail?

Sleep lower than the highest point you reached in the day where possible, take rest days when advised and rise gradually. Stay a night in places such as Ghunsa rather than rushing through. Never go higher with symptoms, and tell your guide if you feel unwell.

What altitude symptoms mean I should go down?

A headache that keeps getting worse, repeated vomiting, unsteady walking, confusion or breathlessness at rest are serious signs. Descend and seek help. Mild headache and tiredness should ease with rest and fluids, but do not climb higher until they have gone.

What insurance do I need for the north Kanchenjunga trek?

Choose a policy that covers trekking at the altitudes of your route and emergency helicopter evacuation. This is a remote trail, so confirm with your operator how evacuation would work and keep your policy number and the insurer's emergency contact with you.

How do I stay warm at the viewpoints?

Carry a warm layer for viewpoint stops, since the wind is cold even on a clear day. Add a hat and gloves, and keep camera batteries warm inside your jacket. Mornings are often cold at the higher camps, so dress in layers you can adjust.

Are there hazards for trekkers in the shadow of Jannu?

Trekkers stay on the valley trail, not on the mountain, so the main risks are altitude, cold and changing weather. The stories of climbers belong to the face itself. Follow your guide, start early and accept a delay if the weather turns.

Is the water on the north Kanchenjunga trail safe to drink?

Treat all water. Use purification tablets, a filter or boiled water, and avoid buying plastic bottles where you can. Stomach upsets are harder to manage in remote places, so wash your hands before meals and carry basic medicines.
