The short version: three of the most asked questions, answered in a line each. The rest of the page goes into detail.
- At which viewpoints should I worry about altitude sickness? Take it seriously on anything above about 3,000 m.
- How cold is a sunrise climb and what should I wear? Dawn is cold at any viewpoint, even on short hikes.
- Do I need travel insurance for the high viewpoints? Yes, especially for Gokyo Ri and Kala Patthar.
At which viewpoints should I worry about altitude sickness?
Take it seriously on anything above about 3,000 m. Poon Hill is about 3,210 m, Kalinchowk about 3,842 m, Tengboche about 3,860 m and the Mardi Himal upper viewpoint about 4,200 m. Gokyo Ri and Kala Patthar are far higher, so walk slowly and drink water.
What should I do if I get a headache on a high viewpoint hike?
Stop, rest and tell your guide or group. If the headache and nausea get worse, descend, because going down is the most reliable treatment for altitude sickness. Do not climb higher until symptoms clear, and remember that the view is never worth ignoring warning signs.
How cold is a sunrise climb and what should I wear?
Dawn is cold at any viewpoint, even on short hikes. Wear a warm hat, gloves and a windproof layer over your base layers, and add a down jacket at higher spots. Mornings are the coldest time of day, so dress for standing still at the top.
Is it safe to walk up a viewpoint in the dark?
It is manageable if you prepare. Carry a headlamp with fresh batteries, stay on the main path and walk at a steady pace, since the climb in the dark can feel slow. Go with a guide or others if possible, and check the forecast the night before.
Do I need travel insurance for the high viewpoints?
Yes, especially for Gokyo Ri and Kala Patthar. Choose a policy that covers trekking at the altitudes you plan to reach and helicopter evacuation, and read the exclusions. Check the details with your insurer or operator before you fly, because policies differ.
How should I eat and drink before an early climb?
Drink water steadily the day before and bring a snack and water with you, because stalls may not be open early. A light, carbohydrate-rich breakfast or tea before you leave helps. Avoid rushing up the hill hungry or dehydrated, which can make headaches worse.
Should I walk to a sunrise viewpoint on my own in the dark?
On the lower, well-used hills many people do, but it is safer with a guide or a companion. Trails can be unclear before dawn and temperatures are low. For high viewpoints such as Gokyo Ri or Kala Patthar, go with a guide who knows the conditions.
