Ten mistakes first-time trekkers make in Nepal, and how to avoid them

The most common first-trek mistakes in Nepal are choosing a route that is too long for the time available, climbing too fast, skipping rest days, wearing new boots, packing too much, buying thin insurance, leaving no spare days, ignoring early altitude symptoms, rushing the pace and booking at the last minute without checking permits and the guide. Every one of these is avoidable with a little planning.

This guide goes through the ten that cause the most trouble, with the reason each matters and a fix you can apply before you leave.

1. Choosing a route that is too ambitious for your time

First-timers often pick a famous route and then try to squeeze it into too few days. The Annapurna Circuit in our plan takes 14 days and crosses Thorong La at 5,416 m; Everest Base Camp takes 12 days and reaches 5,545 m at Kala Patthar. Trying to do either in a week, or flying in and out with no spare days, builds your risk of altitude sickness and of missing flights. The fix is to choose the route that fits the days you actually have. The four-day Poon Hill trek is a real Himalayan trek with a 3,210 m high point and much less risk. Our days needed guide and decision guide help you match time and route.

2. Going up too fast and skipping rest days

Altitude sickness is the biggest risk on the high routes, and it is mostly about speed. The CDC suggests, above 3,000 m, raising your sleeping altitude by no more than about 500 m a night and adding an extra night for every 1,000 m gained. Wilderness Medical Society guidance also points to gradual ascent as the main protection. A plan that goes from 3,440 m to 4,410 m with no rest day, or that skips the acclimatisation days at Namche Bazaar and Dingboche, is asking for trouble. The fix is to follow a plan with rest days and not to cut them to save a day. Read altitude sickness basics and acclimatisation schedule before you book.

3. Wearing new boots

A blister on day two of a seven-day trek is painful and can force you to walk badly for the rest of the trip. New boots are the usual cause. The fix is to buy your boots weeks or months before you leave, walk in them on hills with the socks you will wear and treat any hot spots early. Use blister plasters at the first sign of rubbing, not after it breaks. Rent bulky items such as a down jacket and sleeping bag in Kathmandu or Pokhara; do not rent boots, because a good fit matters. Our down jacket rent or buy guide explains what to rent.

4. Overpacking

Every extra kilogram has to be carried up a valley by a porter, and an overloaded duffel slows the whole team. Most first-timers bring too many clothes, gadgets and toiletries. The fix is to pack for layers: a base layer, a warm mid layer, a shell, a down jacket for the highest nights, two or three changes of socks and underwear and one set of evening clothes. You wear the same trekking clothes for days; nobody minds. Leave valuables and spare clothes at your Kathmandu hotel, and use our packing list to check what you really need.

5. Thin or missing insurance

A helicopter evacuation costs far more than most people expect, and a standard travel policy may exclude trekking above a set altitude or exclude helicopter rescue. The fix is to buy insurance that explicitly covers trekking to your highest altitude and helicopter evacuation, and to read the exclusions. The Everest route notes list cover to about 6,000 m as the sensible standard. Carry the policy number, the insurer's emergency number and a copy of your passport, and tell your guide where they are.

6. No spare days

Flights to Lukla and Jomsom are often delayed or cancelled for weather, roads slip in the monsoon and a day of illness can ruin a tight schedule. Trekkers who book international flights the day after they get back from the trail are the ones who panic. The fix is to build in at least one spare day, ideally two, at the end of the trip, and to book flexible flights. Our guide to buffer days explains how to plan them.

7. Ignoring early altitude symptoms

A mild headache, nausea or poor sleep at 3,500 m is common, and most people shrug it off. The right response is to tell your guide, rest, drink and not go higher until the symptoms settle. Breathlessness at rest, a wet cough, confusion or loss of coordination means descend immediately. The CDC and the Wilderness Medical Society both treat descent as the key response to worsening illness. The fix is to learn the warning signs before you go, and to tell your guide and partners about every symptom, even small ones. Our guides on what normal looks like at altitude and HAPE and HACE warning signs explain what to watch for.

8. Walking too fast

Beginners often start at a pace that feels good at 2,000 m and that they cannot keep at 4,000 m. They get ahead of the group, tire early and miss the views. The fix is to walk slowly enough that you can hold a conversation uphill, take regular short breaks and let the guide set the pace. The first hour of a day on a staircase like Ulleri on the Poon Hill route is where many people burn out. If you feel you are slower than your partners, say so; a good partner will adjust. Our guide to matching pace and fitness with partners helps with that conversation.

9. Not drinking, eating or washing hands enough

Dehydration and stomach upsets are common, and altitude suppresses appetite. Many first-timers drink too little because they dislike stopping, or they eat only a little because dal bhat is unfamiliar. The fix is to drink regularly through the day, eat dinner and breakfast even if you are not hungry, and wash your hands or use sanitiser before meals. Stick to cooked food, boiled or treated water and be cautious with salads and raw items. The NHS Fit for Travel Nepal page and the CDC both give general food and water advice for travellers, and our guide to dal bhat and the teahouse menu explains what to order.

10. Booking late and skipping the paperwork

The last mistake is leaving planning until the week before, then discovering that flights and lodges are full, or not checking permits and the guide rule. A licensed guide through a registered agency is required in restricted areas (Department of Immigration) and, under the Nepal Tourism Board rule of April 2023, in national parks and conservation areas, where 2026 operator reports say checkpoints enforce it in Annapurna and Langtang but not in Khumbu (checked 19 October 2026). Showing up without the right permits can cost time and money. The fix is to book two to three months ahead for the peak months, ask your agency to confirm permits, and follow our guide on how to book a Nepal trek.
