The short version: three of the most asked questions, answered in a line each. The rest of the page goes into detail.
- Which symptoms mean I should stop climbing? Persistent headache, vomiting, unusual breathlessness at rest, confusion or loss of balance mean you should stop climbing and tell your guide.
- What insurance cover do I need? You need travel insurance with climbing and rescue cover, and it should include helicopter evacuation and cover for altitudes above Pangpema at about 5,140 m.
- How do I stay safe on narrow trails and rough bridges? Walk slowly, keep your trekking poles ready and let animals pass on the uphill side.
How serious is altitude sickness on this route?
It is a real risk above 4,000 m. The sleeping altitude rises slowly, with a rest day at Ghunsa at about 3,595 m, then Lhonak at about 4,780 m and Pangpema at about 5,140 m. Go up slowly, drink well and descend if symptoms worsen.
How quickly can I be rescued if something goes wrong?
Rescue is slow. There are few clinics, no road above the lower villages and weather can stop helicopters. That is why itineraries include extra days, a medical kit and guides who know the valley. Tell your guide about every symptom early rather than waiting.
Which symptoms mean I should stop climbing?
Persistent headache, vomiting, unusual breathlessness at rest, confusion or loss of balance mean you should stop climbing and tell your guide. Rest or go down if they do not improve. Do not push higher to reach the base camp when you feel unwell.
Why do groups often sleep at Lhonak and visit Pangpema in a day?
Because the sleeping altitude stays lower. Many groups spend a night at Lhonak, at about 4,780 m, then walk to Pangpema, at about 5,140 m, and back in a long day. It is a standard way to reduce the risk of sleeping above 5,000 m.
How should I train for such a long trek?
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. Previous treks above 4,000 m help a lot.
What insurance cover do I need?
You need travel insurance with climbing and rescue cover, and it should include helicopter evacuation and cover for altitudes above Pangpema at about 5,140 m. Read the exclusions carefully. Bring the policy details with you, and give your operator a copy before you leave Kathmandu.
How do I stay safe on narrow trails and rough bridges?
Walk slowly, keep your trekking poles ready and let animals pass on the uphill side. Trails are narrow, rocky and steep in places, and bridges can be rough. Monsoon landslides sometimes change routes, so follow your guide and do not cross damaged sections.
