Vietnam is roughly 1,600 kilometres from top to bottom and rarely more than a couple of hundred wide, and that shape decides almost every transport question you will have. The workable answer for most trips is to fly the long gaps, take the train for the two or three segments where it is genuinely beautiful, and use road transport for everything local. Trying to travel the whole country overland is a good story and a poor use of a two-week holiday.

This guide covers how to choose between the modes, which rail segments earn the time, what sleeper buses are actually like, an honest read on motorbikes, and the order to book things in. If you are still working out entry paperwork, our Vietnam visa guide covers that side.

In this guide:

Why Vietnam’s shape decides your plan

Almost every Vietnam itinerary is a north to south or south to north line, because the country offers no other geometry. Hanoi and the northern mountains sit at one end, Ho Chi Minh City and the Mekong Delta at the other, and the middle holds Hue, Da Nang, Hoi An and the coast.

The distances between those clusters are larger than the map suggests, because average road speeds are low and the railway is not fast. Hanoi to Hue is an overnight journey by rail or road. Hue to Ho Chi Minh City is another very long one. Stringing them together overland eats three or four travel days from a fortnight.

The efficient pattern is therefore to treat the country as three regions, fly between them, and use ground transport generously inside each. That gives you a northern block, a central block and a southern block, with two flights connecting them and no wasted days.

Domestic flights: the backbone of a short trip

Vietnam’s domestic network is dense and competitive. Several carriers fly the main corridors many times a day, and fares are low enough that a flight often costs little more than a good sleeper bus while saving most of a day.

The routes that matter are Hanoi to Da Nang, Da Nang to Ho Chi Minh City, and the full Hanoi to Ho Chi Minh City run. Da Nang is the gateway for Hoi An and, at a stretch, Hue, so a central stop is easy to slot in.

Two practical notes. Domestic terminals sit apart from the international ones at the main airports, and the walk or shuttle between them is longer than it looks when you are the one making the connection rather than an airline, so a self-booked same-day transfer needs real slack rather than the hour you would allow at home. And fares here climb steadily toward departure rather than dropping in a late sale, which makes booking as soon as your dates firm up the whole discipline.

Around the lunar new year holiday the entire country travels at once. Flights sell out and prices multiply. If your trip overlaps that window, book flights months rather than weeks ahead.

The Reunification railway, segment by segment

The line running the length of the country is one of the great railway journeys, and also a slow way to cover ground. The trick is to use it in pieces.

The segment worth planning around is the coastal stretch between Hue and Da Nang. The track clings to the shoreline and climbs over the Hai Van Pass with the sea on one side and mountains on the other, and it takes only a few hours. Sit on the seaward side, keep your phone charged, and treat it as an attraction rather than a transfer. It is the single most rewarding rail leg in the country.

Overnight segments in the middle of the line are the other good use. A soft sleeper berth on a long leg replaces a hotel night and delivers you somewhere new in the morning. Carriages come in tiers: hard seat, soft seat, hard sleeper with six berths and soft sleeper with four. Soft sleeper is the one worth paying for on an overnight; the lower berths are more comfortable and get taken first. Some routes also have privately branded carriages attached to regular trains, with better fittings at a higher price.

What to avoid is the full end-to-end run unless the train itself is your goal. It takes well over a day, the scenery is not continuously spectacular, and you arrive tired at a city you could have reached in two hours.

Buy tickets through the national operator’s site, a reputable agent or at a station counter. Trains run to a published timetable but delays accumulate over long distances, so leave slack after any overnight arrival.

Sleeper buses and limousine vans

Vietnam runs on sleeper buses. On any route the train does not serve well, an overnight coach with lie-flat berths will, at a low price and often through the night.

Quality varies more than any other mode. The established operators run modern vehicles with proper berths, curtains, air conditioning and a rest stop; the cheapest run older buses driven fast. Berths are also sized for the average Vietnamese frame, so travellers over about 180 centimetres often find them cramped. Book through a hotel or an established booking platform and pay slightly more for a named operator rather than taking whatever is cheapest at the terminal.

Practical points: shoes come off and go in a bag at the door, the aisle berths are narrower than the window ones, and the upper deck sways more than the lower. Keep your passport, phone and money on your person rather than in the luggage hold, and set an alarm, because drop-offs happen at whatever hour the bus arrives.

The other road option is the limousine van, a nine to sixteen seat minibus with proper reclining seats, usually with door-to-door pickup. On medium-distance routes such as Hanoi to Ninh Binh or Ha Long, they are faster and considerably more comfortable than a full-size coach for a modest premium. For journeys of two to five hours, this is often the best value transport in the country.

Motorbikes: an honest assessment

Two-wheelers are how Vietnam moves, and riding one through the northern mountains or the Hai Van Pass is a highlight for people who do it well.

It is also where visitors get hurt. Vietnam has a high road fatality rate, traffic follows conventions that take time to read, and rural roads mix trucks, livestock and unlit vehicles. Helmets are legally required for rider and passenger, and driving without third-party insurance is illegal.

The licence question, and why your insurer cares

The licence question is the part most visitors get wrong, and it is worth settling before you sit on anything. Vietnam recognises international driving permits issued under the 1968 Vienna Convention, carried alongside your own national licence and covering the correct motorcycle category. Permits issued under the older 1949 Geneva Convention, which several major licence-issuing countries still use, are a different document. The consequence of turning up with the wrong one is not only a roadside fine. Travel insurers routinely exclude motorbike injuries when the rider was not legally licensed for the machine, and a crash without cover is a very expensive problem in a country where you pay for treatment upfront.

Do not take a rental shop’s word for any of this, because the shop is not the party who will decline your claim. Confirm with your own licensing authority which convention your country issues permits under, get your insurer’s position in writing rather than by inference from a policy summary, and read your government’s current advice for Vietnam before you travel; the UK guidance on driving there is a clear example of the level of detail worth looking for.

If you want the experience with the risk managed, there are good middle paths. Ride only on quiet rural loops rather than national highways. Take an easy-rider trip where an experienced local rides and you sit behind. Or hire a car with a driver for a day, which costs less than most people expect and removes the problem entirely.

If you do ride, wear a proper helmet rather than the token one supplied, check the brakes before leaving the shop, photograph the bike’s existing damage, and never hand over your passport as a deposit for a rental or as a guarantee against a fine.

Moving around inside cities

Ride-hailing apps dominate Hanoi, Ho Chi Minh City and Da Nang, offering both cars and motorbike taxis. The motorbike option is remarkably cheap, quick through traffic and perfectly reasonable for short hops in daylight without luggage. The car option is the sensible choice with bags or in rain. Either way, the price is fixed in the app, which removes the entire negotiation problem.

Metered taxis are fine from the reputable companies. Airport arrivals halls attract drivers offering rides at inflated prices; walk to the app pickup zone or the official rank instead. Airport buses run to the centre of the main cities for a fraction of a taxi fare and are easy to use if you are not arriving late.

Walking in Vietnamese cities requires a technique that feels wrong the first time: cross the road at a steady, predictable pace and let the traffic flow around you. Stopping suddenly or dashing is what causes problems. Pavements are frequently occupied by parked scooters and food stalls, so expect to walk in the road and accept it as normal.

What to book in advance

Vietnam has one rule and one exception, which is fewer moving parts than most countries.

The rule is that the flights are the only thing worth booking far ahead. Two internal hops hold a three-region itinerary together, fares climb steadily toward departure, and the main corridors are busy, so those go in the calendar as soon as your dates are real. A soft sleeper berth on a popular overnight rail leg, a named operator’s sleeper bus and a limousine van on a busy weekend route want a day or two of notice, not months. Everything else, meaning city transport, ride-hailing, day trips, local buses and almost all tours, is cheaper arranged in person and costs you nothing to leave open. That matters more here than it sounds, because a country with three distinct climate zones will hand you weather you want to move a day around.

The exception is the lunar new year holiday, when the whole country travels at once, flights sell out and prices multiply. If your trip overlaps it, either book everything as far ahead as the operators allow or move the fortnight.

Staying connected between cities

Vietnam’s transport runs on your phone more than most places. Ride-hailing is the default way to get a car or a bike. Bus and train tickets arrive as codes in a messaging app. Drop-off points for sleeper buses are frequently not the address you were told, so you will be finding your way from an unfamiliar street corner at six in the morning. Translation apps carry a lot of weight at bus stations and rural stops.

Cafe and hotel wifi in Vietnam is genuinely good, which lulls people into travelling without data. The gap shows up in exactly the moments that matter: booking a ride outside a bus terminal, confirming a station change, or reading a map on a mountain road with no signal from a hotspot in sight.

A prepaid travel eSIM is the straightforward fix. It installs before you fly, activates when you land, and is a one-off purchase rather than any kind of recurring plan, with your usual number still active alongside for bank codes and calls. Current Vietnam eSIM plans show live options, and our best eSIM for Vietnam guide covers how much data a two-week trip realistically needs.

The moment that catches people out is a six in the morning drop-off at a street corner nobody named. What turns that into a five-minute walk is an offline map you downloaded in the city the night before, because coverage thins along the Ha Giang loop and through parts of the northern mountains and the sleeper bus does not care. Bookings deserve the same treatment: a QR code that will not load at a station counter is the same as no ticket.

Two itinerary shapes that work

For ten to twelve days, run three regions with two flights. Four nights in Hanoi with a trip out to Ha Long or Ninh Binh by limousine van, fly to Da Nang, four nights split between Hoi An and Hue with the coastal train segment between them, then fly to Ho Chi Minh City for three nights with a day in the Mekong Delta.

For three weeks, add the north properly. Start with Hanoi, then take a sleeper bus or private car up to Ha Giang and give the loop three or four days with a local rider, come back through Sapa or Ninh Binh, and only then start the flight-assisted run south. That version uses the ground transport where the ground is the point, and the aircraft where it is not, which is the whole trick to moving around Vietnam without spending your holiday in transit.
