The short version: three of the most asked questions, answered in a line each. The rest of the page goes into detail.
- Why does the Cho La need more care than the main Everest trail? The Cho La reaches about 5,420 m, and the villages around it, such as Dzongla and Dragnag, are high.
- How should I acclimatise before crossing the Cho La? Spend a rest night at Dingboche or Gokyo before the crossing, climb high and sleep low, and avoid adding days of rapid gain.
- Which symptoms mean I should descend at once? Confusion, loss of balance and severe breathlessness need immediate descent.
Why does the Cho La need more care than the main Everest trail?
The Cho La reaches about 5,420 m, and the villages around it, such as Dzongla and Dragnag, are high. Nights are cold and help is further away than on the main path. Plan your acclimatisation carefully, and do not treat the crossing as just another walking day.
How should I acclimatise before crossing the Cho La?
Spend a rest night at Dingboche or Gokyo before the crossing, climb high and sleep low, and avoid adding days of rapid gain. A sensible profile matters more here than on the main trail. Rest the night before the pass at Dzongla or Dragnag.
Which symptoms mean I should descend at once?
Confusion, loss of balance and severe breathlessness need immediate descent. Headache, poor sleep, loss of appetite and vomiting are early warning signs, and they mean you should not go higher. Tell your guide straight away rather than hoping the symptoms pass.
Do I need microspikes for the Cho La?
They help in early or late season, when the pass can be icy or snowy and the glacier on the far side needs care. Your guide will know current conditions. Go with someone experienced, and ask whether spikes are needed for your dates before you pack.
What insurance should I carry for a Cholatse trek?
Choose a policy that covers trekking to at least 5,600 m and includes helicopter evacuation. If you plan to climb the peak itself, you need cover that explicitly includes climbing at that altitude and helicopter rescue. Check the exclusions before you buy.
How much should I drink on the way to the pass?
Aim for three or more litres a day and eat even when your appetite is low. Cold air dries you out quickly, and a headache is often an early sign that you need more water. Keep your hands warm and wear layers so you stay comfortable.
Should I cross the Cho La if I feel unwell?
No. The crossing is a long day, often starting before dawn, so do not start if you feel unwell. If you do cross, descend to a lower village afterwards rather than staying high. Poor weather is another reason to wait, because a rest day is cheaper than an emergency.
