Vietnam looks thin on a map, which is exactly why so many itineraries go wrong. The country stretches well over a thousand kilometres from Hanoi to the Mekong Delta, and the places most people want to see are spread from top to bottom. You can travel its full length in two weeks. You will also spend a lot of it watching the country through a window.

This guide is for the traveller with two to four weeks trying to decide how much of Vietnam to attempt: the route shapes that work, what each costs in travel days, which section to cut, and how to handle the sleeper trains and night buses.

The one decision worth making before you book anything: pick a single anchor region, then work outwards. Trying to see Vietnam from Hanoi to Phu Quoc in a fortnight means six or seven transit days — nearly half the trip spent in motion.

How much of Vietnam you can honestly cover

Count usable days, not calendar days. A long hop costs you a morning, an afternoon or a night, plus the relaxed version of wherever you were.

A rough shape that holds up in practice:

• 10–12 days: one region done properly — either the north (Hanoi, the mountains, one bay) or the centre (Hue, Da Nang, Hoi An) with a short southern finish.
• 14 days: two regions with one long hop between them, for example north plus centre, flying the middle leg.
• 18–21 days: the classic north-to-south run at a sane pace, with three or four stops of three nights and two internal flights to skip the dull stretches.
• Three to four weeks: the full length overland, with room for the Ha Giang loop, a bay, the centre and the delta, still with a flight or two.

Weather decides direction as much as preference does. The north has a real winter, the south is warm all year with a distinct wet season, and the centre has a late-year rain and storm window. Check the monthly pattern for your months and confirm conditions before you go; the same route can be excellent or miserable depending on timing.

The four route shapes, and who each one suits

Rather than a day-by-day plan, think in shapes. Each is a real choice with a real tradeoff.

If you have two weeks, the north-plus-centre shape beats the full run almost every time. You see three versions of the country — mountains, old imperial capital, coast — and spend your transit budget on one flight rather than a week of buses.

Skip the full overland run if your priority is a relaxed holiday. Skip the north-only plan if what you actually want is warm water and seafood, because the northern winter is genuinely cold.

The north: Hanoi, Ha Giang, Ha Long and Cat Ba

Hanoi is the best place in the country to learn how to cross a road, eat well for very little and sit on a plastic stool at 7am without feeling self-conscious. Stay around Hoan Kiem and the Old Quarter for atmosphere and street food within walking distance, Ba Dinh for a calmer residential feel near the mausoleum and the Temple of Literature, or Tay Ho for lake views and a newer restaurant scene.

Give Hanoi three nights, not one. The city rewards a slow morning and a second bowl of pho at a different stall, and day trips out to the ceramic village at Bat Trang or the Perfume Pagoda each need a full day.

From Hanoi, the northern add-ons are the mountains and the bays, and they pull in different directions:

• Ha Giang, on the northern loop, is the most dramatic riding in Vietnam. You can ride it yourself, hire an easy rider, or join a small-group tour. Rules on licences, permits and what insurance covers vary, so confirm current requirements and check your policy before you commit.
• Sapa and the far north-west are more developed, easier to reach by overnight train from Hanoi, and better if you want trekking with established homestays rather than motorbike days.
• Ha Long Bay is the famous one and the busiest. Lan Ha Bay, reached via Cat Ba island, has similar limestone scenery with fewer boats and a better chance of a quiet kayak.

Two nights on a boat beats one, which is often just a rushed transfer with a cave stop. One night plus two on Cat Ba is a good compromise if you want to hike and swim too. If you would rather not assemble boat, transfer and permit logistics yourself, see tour options for the bay or the mountain loop — but skip the packaged tour if you would rather stay an extra day in one place than move every morning, which is a perfectly good use of the same money.

The centre: Hue, Da Nang, Hoi An and the Hai Van Pass

The centre is where most travellers accidentally spend too little time. Hue has the imperial citadel, the Perfume River, royal tombs scattered in the countryside and a distinct local cuisine built around bun bo Hue and small dishes served in tasting portions. It is also the best place in the country to spend a rainy day.

Da Nang is the practical hub: an airport, a long beach at My Khe, the Marble Mountains, and easy access in both directions. Hoi An, a short drive south, is the postcard town — lanterns, tailors, the covered bridge and the market. It is also the most crowded stop on this route in high season, so staying just outside the old town near An Bang beach or Tra Que village gives you the same access with less noise.

The coast between Hue and Da Nang over the Hai Van Pass is one of the best short rides in the country. Do it by rented motorbike, by easy rider, or by car with a stop at the top for the view over Lang Co bay. If you take the train instead, sit on the seaward side: the pass section is the scenic part, so time that leg for daylight.

Practical notes for the centre:

1. Book Hoi An accommodation early in the lantern-heavy months, because good small hotels fill weeks out.
2. Keep one flexible day in the middle, because central Vietnam floods and storms late in the year.
3. Carry cash for the old town, markets and small eateries, and use cards in larger hotels and restaurants.
4. Rent bicycles rather than motorbikes for the Hoi An countryside; the lanes around Tra Que and the rice fields are flat, quiet and better at walking pace.

The south: Ho Chi Minh City, the Mekong and the islands

Ho Chi Minh City is louder, faster and more commercially alive than Hanoi, and it rewards a different approach. Base yourself in District 1 for convenience or District 3 for a calmer, more local neighbourhood with excellent coffee, and use taxis and ride-hailing rather than trying to walk long distances in the heat. Two or three nights covers the War Remnants Museum, the Reunification Palace, the markets and the coffee culture.

The Mekong Delta is why many people come south. Can Tho is the usual base for the floating markets, which are best seen early, and Ben Tre is a gentler introduction with fewer tour groups. Two days is the realistic minimum; a single-day return trip from the city spends most of its time in a minibus.

For beach time, the options are genuinely different:

• Phu Quoc has the resorts, the flights and the easiest logistics, and is the most developed of the islands.
• Mui Ne is for kitesurfing and long, windy sand, reachable by train or bus from the city. Inland, Da Lat is the cool-weather escape if you have had enough heat.

Sleeper trains, night buses and domestic flights

Vietnam’s railway is the most comfortable way to cover long distances if you plan it well, and the least comfortable if you don’t. The Reunification Express links Hanoi and Ho Chi Minh City the length of the country, with the most useful legs for travellers being Hanoi to Hue or Da Nang, and Da Nang southwards. Even the faster services take more than a day end to end, so almost everyone breaks the journey up.

Booking practice matters more than the train itself:

• Sleeper carriages come in four-berth and six-berth versions. The four-berth is worth the extra for quiet and a door that locks; the six-berth is fine if you are a group happy with the cheaper fare.
• Lower berths are easier for long trips; upper berths give more privacy and less headroom.
• Tickets are released in a booking window ahead of departure and popular dates sell out, so book as early as the window allows rather than deciding on the day.
• Vietnam’s own rail tickets are not sold through the big Western rail retailers, so book through the operator or a local agent. If your trip also includes rail legs in Europe either side of the flight, price those separately instead of bundling: check rail fares to see what point-to-point pricing looks like.

Night buses are cheaper and go more places, including routes with no useful train. They are also narrow, bouncy and frequent. If you are tall, prone to motion sickness or a light sleeper, pay a little more for a daytime bus or a domestic flight. Domestic flights are inexpensive relative to European short-haul and can save two days on a three-week trip; the tradeoff is carbon, and if that matters to you, read the choices that actually cut emissions before you decide.

Sleeping well, eating well and staying well on the move

Hotels and guesthouses are one of Vietnam’s best-value categories, but quality varies more than photos suggest. Read recent reviews rather than trusting a star count, check whether the room has a window — some budget rooms genuinely do not — and ask about nearby construction. Book the first two nights of each stop and leave the rest flexible; check hotel availability for cancellable rates so a change of plan costs you nothing.

Two habits make long transit legs much easier. First, carry a power bank that can charge a phone more than twice, because overnight trains and buses do not reliably have working sockets: based on published specifications, the Anker 737 Power Bank is built to deliver enough output to top up a laptop as well as a phone — check current price. Skip it if you can charge in your room each night, where a small pocket battery is enough. Second, pack so one bag holds everything you need on a sleeper: valuables, a light layer, water, a snack and your documents, with the main bag stowed.

Eating is the easiest part of travelling in Vietnam. The food is regional, cheap and quick, and the busiest stall is almost always the right one. Our guide to street food without losing days covers the practical rules, and for luggage the two-week one-bag packing list is a sensible starting point.

Frequently asked questions

Should you travel Vietnam north to south or south to north?

Most people go north to south because flights into Hanoi and out of Ho Chi Minh City are easy to combine, and the north’s cold season makes it a natural place to start before the heat. A south-to-north direction can work better in the late-year centre rains, so check the monthly pattern for your specific stops.

How many days do you need for the full length of Vietnam?

Three weeks is the realistic minimum for a north-to-south trip without constant transit days, and four weeks is comfortable. Under two weeks, choose one region instead — the trip will be better, not lesser.

Are sleeper trains in Vietnam worth it?

Yes, if you book a four-berth sleeper and treat the journey as part of the trip rather than dead time. They save a hotel night and the coastal sections are genuinely scenic. If you sleep badly on trains, take a daytime service or a short flight; arriving wrecked costs more than the fare you saved.

Is it better to book tours or arrange things yourself?

For the Ha Giang loop, a boat in Lan Ha Bay and multi-day trekking, organised tours remove permit, transfer and safety questions that are genuinely fiddly. For cities, the centre and the delta, arranging things yourself is easy and usually cheaper. A useful rule: book a tour when the logistics involve a permit, a boat or a mountain road.

The bottom line

Decide first how many days you can spend actually being somewhere, then pick the shortest route that covers what you care about. For most two-week trips that means the north plus the centre, with one flight in the middle and no pretence of seeing the Mekong. For three weeks or more, the full run works when you book the long train legs early, fly one or two stretches, and give every stop at least three nights.

The travellers who come home happiest from Vietnam are rarely the ones who saw the most places. They are the ones who spent four nights somewhere small, learned the morning food stall by name, and took the train because the train was nicer.
