The short version: three of the most asked questions, answered in a line each. The rest of the page goes into detail.
- How should I acclimatise on the way to 5,364 m? Climb gradually, add rest days at recommended stops and drink plenty of water.
- Which symptoms mean I should go down? Go down for a worsening headache, vomiting, breathlessness at rest, confusion or poor balance.
- How do I stay warm in a teahouse? Teahouses are not heated, except for a stove in the dining room that is usually lit in the evening.
How should I acclimatise on the way to 5,364 m?
Climb gradually, add rest days at recommended stops and drink plenty of water. Everest Base Camp is at 5,364 m and Gorak Shep at about 5,164 m, so the air is thin for several days. Follow your guide's pacing instead of trying to hurry.
Which symptoms mean I should go down?
Go down for a worsening headache, vomiting, breathlessness at rest, confusion or poor balance. The main safety rule is not to ascend with symptoms and to descend if they get worse. Tell your guide early rather than hoping they pass.
How cold are the nights at Lobuche and Gorak Shep?
Very cold. Nights at the highest villages can be minus 15 C or lower in the cold months. In spring and autumn the daytime temperature at base camp is around zero to 10 degrees Celsius in the sun, but nights are often minus 10 or colder.
How do I stay warm in a teahouse?
Teahouses are not heated, except for a stove in the dining room that is usually lit in the evening. Bedrooms are cold, so bring a warm sleeping bag, wear layers to bed and ask your guide about hot water bottles.
Do I need helicopter evacuation insurance?
Yes. Choose travel insurance that covers trekking at high altitude and helicopter evacuation, and check the maximum altitude it covers. Take the policy details with you. The trail is remote and weather can delay rescue.
Is the water on the trail safe to drink?
Treat all water. Use purification tablets, a filter or boiled water, and avoid drinking from streams. Buying bottled water adds plastic waste in the mountains, so a treatment method is better. Hot drinks are also a safe choice.
Is a guide necessary for safety on the Everest trail?
A guide is strongly advisable. They help with pacing, weather, route decisions and symptoms of altitude illness, and can organise help if something goes wrong. Check current rules and what your operator provides when you plan.
