Can you trek in Nepal with kids? The ages, treks and altitude rules that actually matter

The short answer: yes, children can trek in Nepal, but age is not the deciding factor, altitude is. There is no legal minimum age for trekking, operators commonly set their own limits, and the medical advice for children at altitude is the same as it is for adults: sleep higher slowly. Below are the ages operators work to and the treks I would and would not choose.

Children are as prone to altitude sickness as adults

The CDC Yellow Book states that children are as susceptible to altitude illness as adults. The extra problem is communication: a young child may not say they have a headache or nausea. The CDC notes that preverbal children with acute mountain sickness can show loss of appetite, irritability and pallor, so a parent has to watch behaviour, not wait to be told. It also advises against taking unacclimatised infants under 6 weeks old to high altitude.

The pacing guidance for everyone is the same: above 3,000 m, keep the rise in sleeping altitude to about 500 m per night, and add an extra night to acclimatise for every 1,000 m gained. On Everest, that is why sources recommend taking at least eight days from Lukla to Gorak Shep. Acetazolamide has paediatric dosing in the CDC guidance, but that is a decision for your child's doctor before you fly, not something to improvise on a trail.

What I would and would not do

For a first family trek I would choose Poon Hill: short days, teahouses every hour or two, and a high point that sits below the altitude where most acute mountain sickness begins. I would take an older child to ABC only on an itinerary of 10 days or more, so the days are short and there are rest nights. I would not take a child under 12 to Everest Base Camp. The trek reaches nearly 5,400 m, it is remote, and a descent from Gorak Shep takes a full day even with a helicopter on standby, which weather can ground.

Langtang is often listed as a family trek, but this autumn it sits next to the Rasuwa flood zone that the US advisory now marks, so I would not plan it until conditions are confirmed (see the advisory explained). Permits for children vary by permit and age; operators report exemptions for the youngest children in some parks, but confirm this with the agency.

Who this suits, and who it does not

• Suits: families with children who already walk 4-5 hours in a day, who will accept a slow pace and a guide's call to turn around.
• Does not suit: families with under-10s hoping for Everest Base Camp, children with a heart, lung or sickle-cell condition (ask a specialist first), or itineraries with no spare days.

If you want a low, warm and beautiful first trek, look at the 4-day Ghorepani Poon Hill trek, or the 7-day Mardi Himal trek for older children.
