Pheriche aid post: the Himalayan Rescue Association clinic

3 min readUpdated 23 Oct 2026By the Base Camp Hikes trek team

The Himalayan Rescue Association, a Nepali non-profit, runs a seasonal aid post at Pheriche. It has treated altitude illness on this trail for decades and also runs daily talks in the main seasons. Opening dates and fees vary, so check before you rely on it.

What it is

A small clinic staffed in the main trekking seasons, usually by volunteer doctors, with equipment for treating altitude sickness and other mountain problems. Always confirm what is available this season.

What it does

  • Checks and treats altitude illness.
  • Gives advice about whether to continue up or go down.
  • Holds daily talks on altitude sickness in the main seasons.
  • Treats common injuries and illnesses on the trail.

Opening and cost

The post operates mainly in spring and autumn. A consultation normally has a fee, which you should expect to pay. Carry cash and your insurance details.

What it does not replace

A clinic in a remote village is not a hospital. In a serious case, descent and evacuation matter more than a visit. See evacuation costs and paperwork.

Before you go

  • Attend a talk if you can; it is useful and short.
  • Bring a list of medicines you take.
  • Tell your guide before and after any visit.

A note on prevention

Many of the cases the aid post sees come from climbing too fast or ignoring early symptoms. The best help you can give yourself is to follow the ascent rules, drink well and listen to your guide.

What to bring if you visit

  • Your passport details and insurance policy number.
  • A list of medicines you take.
  • Cash for the consultation fee.
  • The names of the people you are travelling with.
