Travelling safely in Nepal is less about caution than about a handful of specific decisions, most of which are made before you arrive. How you cross the country, how fast you gain height, and what you drink account for nearly everything that goes wrong here. The rest is ordinary travel sense.
This is the practical companion to our broader look at whether Nepal is safe to travel. If you want the risk picture, start there. If you have already decided to come, this is the part that matters.
Before you leave home
Insure properly, and read the altitude clause before you pay. Standard travel insurance usually excludes activity above 3,000 to 4,000 m, which is below the top of every popular trek in Nepal, and a policy advertising large medical limits can still refuse a rescue at 5,000 m on that exclusion alone. Nepal has required proof of insurance for trekking permits since 2024, so you need one regardless. What the wording has to say is covered in our guide to travel insurance for Nepal trekking.
Take copies of everything: passport, visa, insurance policy and emergency assistance number, permits, and a couple of passport photographs for the paperwork you will meet along the way. Keep a set on your phone and a set on paper, because the phone is the thing most likely to be lost or dead when you need it.
Register with your embassy if your country offers it. It costs nothing and it is how consular staff find you after an earthquake or a flood.
Check the current advisory for the specific regions you are visiting rather than for the country as a whole. Nepal is regional in almost every respect, and a problem in one district frequently means nothing at all for another.
Choosing how you move around
Road travel is the largest genuine risk in Nepal, so this is the decision with the most safety in it.
Fly the long legs where you can. Kathmandu to Pokhara takes 25 minutes in the air against six to eight hours on the road, and it removes the most exposed stretch of highway in the country from your itinerary. Domestic flights are weather dependent, particularly into Lukla and during the monsoon, so leave a buffer day rather than connecting tightly to an international departure.
For everything else, use a private vehicle with a driver. Someone who works a route regularly knows where it slides, which sections flood, and when to stop and wait. That is the whole reason we run vehicle hire in Pokhara with local drivers. If you are arranging your own transport, look for a driver rather than a car.
Avoid long-distance night buses. They are cheap, and they are where a disproportionate share of serious incidents involving travellers happen, because poor visibility, tired drivers and mountain roads combine badly.
Travel the main routes in daylight, and do not schedule a long drive the day before an international flight. One landslide can hold a highway for a day.
Trekking without getting into trouble
Let the itinerary do the acclimatising for you. Above 3,000 m the usual guidance is to raise your sleeping altitude by no more than 300 to 500 m a day, with a rest day every 900 to 1,000 m. A trek that reaches Annapurna Base Camp at 4,130 m in a compressed schedule costs less because it has moved the risk onto you, so check the daily altitude gains before you book rather than after.
Learn the symptoms and respect them. Headache, nausea, dizziness, breathlessness at rest, loss of appetite and poor sleep are the early signs. Do not climb higher while you have them, do not leave anyone who has them alone, and go down if they worsen. Descending a few hundred metres fixes most cases within hours. Fitness offers no protection here, and strong trekkers get into difficulty more often precisely because they are capable of climbing too fast.
Do not walk remote high routes alone. A guide is required in most conservation and national park areas under current rules anyway, and the value is in weather judgement, altitude assessment, knowing which lodges are open, and being able to organise a helicopter without a language barrier.
Tell someone your route and your expected dates, then check in when you can. Mobile coverage on the main Annapurna and Everest trails is better than most people expect, though it disappears in the side valleys.
Carry the boring things: a headtorch, a small first aid kit with blister cover, rehydration salts, serious sun protection for altitude, and enough warm layers for a night the forecast did not mention.
Water, food and stomachs
Do not drink the tap water anywhere in Nepal, including in good hotels in Kathmandu and Pokhara. That covers ice and brushing your teeth. Bottled, boiled or filtered only. A filter bottle or purification tablets pay for themselves on a trek and spare the trails another few dozen plastic bottles.
Eat where food is moving. Busy places cook fresh. On trek, the conventional advice to lean vegetarian holds up, particularly high on a route, because meat has usually travelled for days without refrigeration. Dal bhat is served everywhere, is cooked to order, and comes with refills.
Carry rehydration salts and take stomach trouble seriously at altitude, where dehydration and acute mountain sickness look similar and compound each other.
Rivers, weather and the monsoon
Between June and September, rain governs everything. Rivers rise fast, hillsides slip, and roads close with no notice.
Never cross a flooded road, a swollen stream or a fresh landslide. Depth and current are routinely misjudged, and a slope that has just slid will often slide again. This is the most common way a manageable situation turns into a fatal one.
Sleep above the river rather than on the flat ground beside it. The 2026 flash flood arrived in daylight, with no rain falling locally and no warning at all, which is exactly why that margin is worth having.
Build slack into any monsoon itinerary. Spare days are the difference between a closed road being an inconvenience and being a missed flight.
If you are here between June and September, take a rain-shadow route. Upper Mustang, Dolpo and Manang sit north of the main Himalayan wall and get under 300 mm of rain a year, so they stay walkable while the rest of the country is under water.
Money, connectivity and paperwork
Get a local SIM at the airport with a data plan. Coverage is good in populated areas and on the main trekking routes, and it is the cheapest safety equipment you can buy. Download offline maps before you leave a town.
Carry cash in rupees outside cities, since card acceptance thins quickly and ATMs are unreliable in hill towns. Split it between two places. Bring a power bank, because lodge charging costs money and is not guaranteed.
Keep your permits accessible. Conservation area and national park permits are checked at posts along the trails, and having them is not optional.
If something happens
Road closed or flooded: stop, stay on high ground, contact whoever arranged your transport, and check with Nepal Police Control on 100 or Traffic Police on 103. Wait it out.
Earthquake: get away from anything that can fall. Indoors, take cover under something solid and stay away from windows and stairwells rather than running outside, where falling masonry is the main danger. Outdoors, move to open ground away from buildings and power lines. Expect aftershocks, and expect phone networks to be congested, so send a text rather than calling.
Altitude emergency: descend. Do not wait for a helicopter at height if walking down is possible, and do not leave the affected person alone.
Medical: Kathmandu and Pokhara both have private clinics used to treating travellers. Call your insurer's emergency assistance line early rather than after paying, because most policies require authorisation before an evacuation.
Save these before you need them: your insurer's 24 hour line and policy number, your embassy, your operator or guide's mobile, and 100 and 103. Tourist police desks operate in Kathmandu and Pokhara.
Give the trip more time than it needs
Give the trip more time than it strictly needs. Nearly every serious problem in Nepal is downstream of a schedule that had no room in it: the night bus taken to save a day, the ascent compressed to fit a flight, the drive attempted in conditions that warranted waiting. Spare days are the cheapest safety measure available, and Nepal is a better trip at a slower pace anyway. Our Pokhara tours and treks are built with that slack in them for the same reason.
FAQ
What is the safest way to travel around Nepal?
Flying between major points and using a private vehicle with a local driver for everything else. Domestic flights cut out the longest and most exposed road sections, and Kathmandu to Pokhara takes 25 minutes against six to eight hours by road. Where you do drive, a private vehicle in daylight with a driver who knows the route is markedly safer than a long-distance night bus, which is where most serious incidents involving travellers occur.
How do I avoid altitude sickness in Nepal?
Ascend slowly, sleep low, and build acclimatisation days into the itinerary before you book it rather than hoping to add them later. Above 3,000 m, a common guideline is to raise your sleeping altitude by no more than 300 to 500 m a day with a rest day every 900 to 1,000 m. Drink more water than feels necessary, skip alcohol at height, and treat headache with nausea or unsteadiness as a signal to stop climbing. Descending several hundred metres resolves most cases quickly.
Can you drink the water in Nepal?
No. Tap water is not safe anywhere in Nepal, including in Kathmandu and Pokhara hotels, and that extends to ice and to brushing your teeth. Use bottled, boiled or filtered water. A filter bottle or purification tablets are worth carrying on trek, both because they cost less than buying bottled water at altitude and because plastic bottles are a real disposal problem on the trails.
What should I do if a road closes or a flood cuts my route in Nepal?
Do not attempt to cross a flooded road, a landslide or a swollen stream on foot or by vehicle. Water depth and current are consistently underestimated, and unstable slopes often slide again. Wait somewhere on high ground, contact whoever arranged your transport, and check conditions with Nepal Police Control on 100 or Traffic Police on 103. Most closures clear in hours, and a night in the wrong town is a far better outcome than the alternative.
What emergency numbers should I have in Nepal?
Nepal Police Control is 100 and Traffic Police is 103, and traffic police are the fastest source of current road conditions. Save your embassy's contact details, your insurer's 24 hour emergency assistance line and policy number, and your guide's or operator's mobile number. Tourist police desks operate in Kathmandu and Pokhara and are used to dealing with visitors.
