Tsum Valley: trail safety, altitude, cold and insurance

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 do I handle the narrow trails and suspension bridges? Go slowly, give way to animals, keep to the inside of narrow sections and use poles.
  • What should I tell my guide each day? Tell your guide how you feel each day, including headache, appetite, sleep and any stomach problems.
  • How cold will it be above 3,000 m? Prepare for cold nights, especially above 3,000 m, with snow possible in the upper valley in colder months.

Do I need to acclimatise on the way up to Mu Gompa?

Yes, take it steadily. The valley rises from Lokpa at about 2,240 m to Mu Gompa at about 3,700 m, and most nights are between 2,300 and 3,400 m. Most healthy trekkers adapt well, but ascend slowly and follow your guide's advice.

What should I do if a landslide blocks the trail?

Do not cross unstable ground on your own. Wait for your guide to assess it, and accept a reroute or a delay. After heavy rain slopes shift, so keep spare days and avoid walking under active slopes.

How do I handle the narrow trails and suspension bridges?

Go slowly, give way to animals, keep to the inside of narrow sections and use poles. Paths run along steep slopes with some exposure, and rough ground with loose stones can be slippery. Stop to look around only where it is safe.

What should I tell my guide each day?

Tell your guide how you feel each day, including headache, appetite, sleep and any stomach problems. Early information makes decisions easier, and you can rest or adjust the plan before a small problem grows. Honest reports matter most on the higher days above Chhokangparo.

How cold will it be above 3,000 m?

Prepare for cold nights, especially above 3,000 m, with snow possible in the upper valley in colder months. A sleeping bag rated to about minus 10 degrees Celsius and warm layers are recommended. Bring a hat, gloves and a down jacket for evenings in the upper villages, because dining rooms warm up only near the stove.

What insurance do I need?

Choose a policy that covers high altitude trekking and helicopter evacuation. Insurance details and emergency contacts are part of the documents for permits, so have the policy in hand when you apply. Read the exclusions and confirm the policy covers your maximum altitude.

Is the water and food in the lodges safe?

Treat all water. Lodge food is simple and hearty, such as dal bhat, noodles, soup and tea, and freshly cooked meals are the safest. Wash your hands, use sanitiser and avoid raw salads. Hot, freshly cooked food is the safest choice, and always carry your own treatment method for drinking water.
