Vietnam needs more time than most first trips give it. Short answer: 14 days is the sweet spot, 10 days works if you drop a region, and 7 days is a real trip only if you pick one region and stay in it. If Vietnam is one leg of a Thailand, Cambodia and Vietnam itinerary of 3 weeks, give it half of those weeks. The reason is geography, not laziness. The North to South railway runs 1,726 kilometers and takes 32 to 36 hours end to end, and every plan that ignores that number turns into a blur of airports. This guide sets out what each trip length actually buys you, how long the legs between places really take, which direction to travel, and which visa fits.
How Long to Spend in Vietnam: The Short Answer
Fourteen days. Two weeks is the length at which Vietnam stops feeling like a series of transfers and starts feeling like a country. Ten days is a good trip if you accept that one of the three regions gets left for next time. Seven days works only as a regional trip rather than a national one. Anything under five days is a city break with a very long flight attached, which is fine as long as you plan it as one.
What decides all of this is the length of the country. Vietnam's main railway runs 1,726 kilometers from Hanoi to Ho Chi Minh City and the through train takes 32 to 36 hours to cover it. That is roughly New York to Miami, and nobody plans a week around both of those cities plus three towns in between. Flying compresses the problem rather than solving it: two hours in the air is still a five or six hour day once you add the transfers, the check-in and the wait.
⚠️ Do not try to do the north, the center and the south in one week. This is the most common mistake in Vietnam planning. Seven days across three regions means two internal flights, three check-ins and roughly nine hours in transit, for the privilege of seeing each place for a day and a half. Pick one region. You will see more of Vietnam by seeing less of it.
| Trip Length | What It Realistically Covers | Visa That Fits | Rough Spend, Mid-Range |
|---|---|---|---|
| 5 to 7 days | One region: the north or the south | 30-day eVisa | USD 250 to 700 |
| 8 to 10 days | Two neighboring regions, one internal flight | 30-day eVisa | USD 400 to 1,000 |
| 12 to 14 days | Hanoi to Ho Chi Minh City, all three regions | 30-day eVisa | USD 600 to 1,400 |
| 21 to 30 days | Adds Ha Giang, Phong Nha, the Delta and an island | 30-day eVisa, watch the exit date | USD 1,050 to 3,000 |
| Over 30 days | Slow travel, long-stay bases, side trips | 90-day eVisa | USD 1,500 and up |
Those figures are days multiplied by a mid-range daily cost of roughly USD 50 to 100, which buys a three-star room, a mix of street food and restaurants, local transport and an attraction most days. International flights are extra. Our guide to how much a Vietnam trip costs breaks that daily figure down.
One Week in Vietnam: Pick One Region and Commit
A week in Vietnam is not a short trip. It is a regional trip, and a very good one if you plan it as such. The rule: one arrival airport, one departure airport, no internal flights, and nothing more than about three hours from your base.
The northern week. Fly into Hanoi and give the city three nights, because Hanoi is dense and rewards walking rather than ticking off sights. Add Ninh Binh, two and a half hours south by train, for the limestone karst without the boat crowds. Then two nights on the water in Ha Long Bay or neighboring Lan Ha Bay, two and a half hours from Hanoi by road. Spend the spare day slowly back in Hanoi rather than on a rushed run at Sapa. Total internal travel: about ten hours, none of it flying.
The southern week. Fly into Ho Chi Minh City. Three nights covers the war history sites, the markets and the food, with the tunnel complexes as a half day out. Two nights in the Mekong Delta based in Can Tho, three and a half to four hours by road, gets you the floating market at dawn, which is the only way to see it properly. Finish with two nights on a beach: Phu Quoc by a one-hour flight, or Mui Ne by road.
Either version leaves out central Vietnam, so no Hoi An, no Hue, no Da Nang, no Phong Nha. That is a real loss with no clever way around it. A 30-day eVisa covers a week comfortably, so the constraint is your leave, not your paperwork. For how road, rail and air compare, see our notes on getting around Vietnam.
Ten Days in Vietnam: Two Regions and One Internal Flight
Ten days is where a Vietnam trip starts to feel national. You get two regions, one internal flight, and enough slack that a rained-out day does not wreck the plan. The only real decision is which two regions.
North plus center. Hanoi for three nights, Ninh Binh for one, Ha Long or Lan Ha for two, then fly Hanoi to Da Nang and give the Hoi An and Da Nang area three nights, with a day trip to Hue or My Son. Fly home from Da Nang. This is the version for landscape, old towns and food, and the internal flight is the cheapest hour of the trip.
Center plus south. Fly into Da Nang, three nights around Hoi An, one or two in Hue, then fly to Ho Chi Minh City for three nights, finishing with two in the Delta or on Phu Quoc. This is the version for cities, war history and a beach, and it is the better choice between roughly September and December, when the center is at its wettest but the south is dry.
Ten days will not stretch to all three regions, and the temptation to try is strong because it looks close on paper. Adding the third costs a second flight and two more check-ins, and cuts every stop to a night and a half. If no place in your draft gets two consecutive nights, you have built a bad plan. Budget roughly USD 400 to 1,000 at a mid-range level, on a 30-day eVisa with room to spare.
Two Weeks in Vietnam: The Full North to South Run
This is the trip most people should take, and the one Vietnam is built for. Fourteen days lets you travel the country end to end in one direction, with two internal flights, and gives every stop the two or three nights it needs. A workable shape, running north to south:
- Hanoi, three nights. The Old Quarter, the citadel, the coffee, the traffic. Do not schedule it tightly.
- Ninh Binh, one or two nights. Two and a half hours by train, for the karst boats and Mua Cave.
- Ha Long or Lan Ha Bay, two nights. Our guide to Ha Long Bay cruises covers how the overnight options differ.
- Fly to Hue or Da Nang, about an hour and twenty minutes in the air.
- Hue, one or two nights. The citadel and the tombs, then the coastal train south rather than the road.
- Hoi An and Da Nang, three nights. Old town, beach, food, and My Son for the Cham ruins.
- Fly to Ho Chi Minh City, about an hour and fifteen minutes.
- Ho Chi Minh City, two or three nights. Our roundup of Ho Chi Minh City tours and day trips covers what fits into a half day.
- Mekong Delta, one or two nights. Do it as an overnight, not a day trip, or skip it.
This leaves out the far north, meaning Ha Giang and Sapa, plus Phong Nha's caves and the southern islands. Two weeks is a complete trip, not an exhaustive one, and the urge to squeeze Ha Giang onto the front is worth resisting: the loop wants four days plus six to eight hours by bus in each direction.
Mid-range spend for 14 days lands around USD 600 to 1,400 plus two flights. A 30-day eVisa covers it with margin, which matters more than it sounds, because the eVisa carries fixed entry and exit dates rather than a rolling clock.
Three Weeks to a Month: The Version With Room in It
Three weeks is where Vietnam gets interesting, because you stop optimizing and start adding. The two-week route above is the spine, and everything below hangs off it.
- Ha Giang, four to five days. The best road journey in the country, and not a day trip from anywhere. Six to eight hours by bus from Hanoi each way, plus three days on the loop. Carry cash; the countryside runs on it.
- Phong Nha, three days. The caves of Quang Binh sit halfway between Hue and Hanoi, which is why two-week itineraries skip them. They are the best argument for the extra week.
- The Mekong Delta, properly. Three or four nights based in Can Tho, moving out to the smaller channels, turns the Delta from a bus tour into a place.
- Phu Quoc or Con Dao, three to four days. Phu Quoc is the easy one, with direct flights and resorts. Con Dao is harder to reach, quieter and more interesting. Pick one; both is a fourth week.
If Vietnam is one leg of a three-country trip, the honest split across three weeks is roughly seven days Thailand, four to five days Cambodia, and nine to ten days Vietnam, entering overland from Cambodia in the south and flying out of Hanoi. Vietnam needs the largest share because it is the longest of the three and the only one whose headline sights sit 1,700 kilometers apart. Anything that gives Vietnam five days out of 21 is a layover, not a leg.
Three weeks still fits inside a 30-day eVisa, but the margin is thin enough to matter. Count your days from the entry date on the visa, not from the day you left home.
Over a Month in Vietnam: Where the 90-Day eVisa Changes the Plan
Past 30 days, the visa stops being paperwork and becomes a planning decision. Vietnam's eVisa is issued for a maximum of 90 days, single or multiple entry, and the version you buy has to cover the whole stay. A trip of 31 days needs the three-month product, and the fee difference is small next to the cost of getting it wrong.
⚠️ A 30-day eVisa is 30 days, not "about a month." If your route runs past four weeks, apply for the 90-day version before you leave. The eVisa carries fixed entry and exit dates taken from your application, and arriving late does not push the exit date back. Extending from inside Vietnam is not a self-service process, and overstaying is an expensive way to end a good trip.
What changes past a month is the shape of the travel, not the list of places. You stop moving every two or three nights and start taking bases: three or four stops of a week or more, with short trips radiating out. Hanoi or Ho Chi Minh City for the city life, Hoi An or Da Nang for the coast, Da Lat or Ninh Binh for the quiet. Weekly and monthly room rates drop sharply against nightly ones, and our guide to where to stay in Vietnam sets out how the regions compare.
The multiple-entry question also becomes real here. If you plan to hop to Cambodia, Laos or Thailand partway through and come back, a single-entry visa ends the moment you leave. That is a five-minute decision at application time and an expensive one to fix afterward. Check what your passport is entitled to on our eligibility pages first, because some nationalities enter visa-free for up to 45 days.
Direction of Travel: Let the Season Decide, Not the Fare
Most people pick their direction by whichever open-jaw flight is cheaper, and that is the wrong input. Vietnam is long enough to hold three distinct climate zones, and the same month can be excellent in one and unpleasant in another. Direction of travel is how you dodge that.
The broad rule: between roughly September and December the center is at its wettest and the far north is cooling, so the south is where you want to finish. Between roughly March and May the north is dry and warming and the whole country works, which is why that window is easiest to plan and busiest. Through the summer the north and center are hot and storm-prone while the south sits in its wet season, which means short daily downpours rather than washouts.
So choose your end point first and work backward. Traveling in the autumn, finish in the south. Traveling in the spring, finish in the north. Our post on the best time to visit Vietnam goes month by month and is the one to read before you lock the direction in. Fares should be the tiebreaker, never the decider: the gap between a Hanoi-in and a Saigon-in booking is a fraction of what a week of bad weather costs you in missed days.
⚠️ Central Vietnam's rainy season is not inconvenient drizzle. Hoi An floods most years, roads over the Hai Van Pass close at short notice, and boat trips get cancelled without warning. If your dates fall in the autumn window, put the center in the middle of the route rather than at the end, so a lost day costs you a stop rather than the last three days of the holiday.
Flying Versus the Train: Which Legs Are Worth the Hours
The rule of thumb: fly the long legs, take the train for the short and scenic ones, and take the road only where there is no alternative. Domestic flights are cheap and frequent, and refusing them on slow-travel principle costs days you do not have.
There is one exception worth planning around, and it is the coastal run between Hue and Da Nang. The line hugs the shore around the Hai Van headland and the views are among the best from any train anywhere. A heritage service now runs it: train HD1 leaves Hue at 07:45 and reaches Da Nang at 10:35, with a ten-minute stop at Lang Co Bay so passengers can get out and look at it. Take that instead of the road tunnel. It is one of the few legs here worth doing for its own sake.
The overnight sleeper is a different calculation. A four-berth soft sleeper from Hanoi to Ho Chi Minh City runs roughly 1,676,000 to 1,792,000 dong, about USD 64 to 69, against a flight of well under USD 50, and takes 32 to 36 hours against two in the air. As transport it makes no sense; as an experience on one shorter leg, Hanoi to Hue or Hanoi to Da Nang, it is worth a night. Our guide to train travel in Vietnam covers booking and berth classes. The times below are typical rather than a timetable, and they exclude the getting-to-the-station part, which is where itineraries quietly lose their afternoons.
| Leg | Best Way | Typical Journey Time | What It Costs Your Itinerary |
|---|---|---|---|
| Hanoi to Ninh Binh | Train | About 2.5 hours | Half a day each way |
| Hanoi to Ha Long Bay | Road | About 2.5 hours | Half a day each way |
| Hanoi to Ha Giang or Sapa | Night bus | 6 to 8 hours | A full travel day |
| Hanoi to Da Nang | Flight | About 1h20 in the air | Most of a day door to door |
| Hanoi to Da Nang | Train | 16 to 17 hours | One night |
| Hue to Da Nang | Heritage train | About 2h50 | A morning, and worth it |
| Da Nang to Hoi An | Road | About 45 minutes | An hour |
| Hanoi to Ho Chi Minh City | Flight | About 2h15 in the air | Most of a day door to door |
| Hanoi to Ho Chi Minh City | Train | 32 to 36 hours | Two nights, effectively |
| Ho Chi Minh City to Can Tho | Road | 3.5 to 4 hours | Half a day each way |
| Ho Chi Minh City to Phu Quoc | Flight | About 1 hour | Half a day door to door |
Over-Allocated and Under-Allocated: Where Your Days Actually Go
Most itinerary guides will not commit to a view on this, so here is one. Some places routinely get more days than they can carry, and others get fewer than they need. Fixing that is worth more than adding two days to the trip.
Over-allocated. Ha Long Bay is the clearest case: spectacular, and a two-night product sold as a three-night one, because the second night on the water largely repeats the first. Nha Trang gets three or four days in a lot of plans and is a large resort city with an average beach. Sapa is beautiful and heavily developed, and the town absorbs a day it has not earned. Ho Chi Minh City is a great city, but two or three nights covers what most visitors want from it, and the fourth day turns into shopping.
Under-allocated. Hoi An is the one people get most wrong. The old town looks small, so it gets a day, and a day is not enough. The admission ticket for the heritage buildings is valid for your whole stay, up to three days, which tells you how the site itself expects to be used. Phong Nha gets skipped by most two-week trips and holds the finest cave systems in the world. Ninh Binh gets a day trip and deserves an overnight, because the landscape is best early, before the boats start. Hue is treated as a stopover and holds a full day of tombs on top of the citadel. And the Delta as a day trip from Ho Chi Minh City is close to pointless, because the floating markets happen at dawn and you cannot be there at dawn from District 1.
The honest summary: move a night from Ha Long to Hoi An, and a night from Nha Trang to Ninh Binh or Hue, and your two-week trip improves without getting any longer.
Tet: The Two Weeks That Rewrite Any Itinerary
Tet is the lunar new year, and the one date that can invalidate an otherwise sensible plan. It moves each year, landing between late January and mid-February, and the holiday around it is long. For 2026 the government approved a nine-day public holiday from February 14 to 22, and the next year's schedule is usually not confirmed until late in the preceding year.
The consequences are specific. Domestic flights and trains sell out weeks ahead and fares rise sharply, because the whole country is traveling home at once. Many family-run restaurants, shops and small hotels close for several days, and heritage sites keep reduced hours. Buses run, but they run full. If your route depends on moving every two or three days, Tet will break it.
The workaround is not to avoid Vietnam at Tet, because the days around it are among the most interesting times to be in the country. It is to change the shape of the trip: pick one or two bases, book transport and rooms well ahead, and be somewhere you are happy to stay put for three or four days. Hanoi and Ho Chi Minh City both empty out and turn unusually quiet. The countryside fills up.
⚠️ Check where Tet falls before you book anything. A trip planned around normal transport availability and then dropped onto the Tet fortnight is the one scheduling error money cannot fix. If your dates fall anywhere near late January or February, confirm the holiday period first and build the itinerary second.
A Few Parting Notes
Vietnam rewards the traveler who does less. The single best change most people can make to a draft itinerary is to delete one stop and give those nights to the places that remain. Two nights is the minimum unit that feels like visiting somewhere; one night is a stopover, and a plan made of stopovers is a plan you will not enjoy.
Book your international flights open-jaw, into one end of the country and out of the other. It costs little more than a return and saves a full day of backtracking. Then decide which end is which by looking at the calendar rather than the fare. On the paperwork, match the visa to the route before anything becomes non-refundable: under 30 days the one-month eVisa is fine, over 30 days you need the three-month version, and if you plan to leave Vietnam and come back you need multiple entry. The standard processing time is three working days, but have it in hand well before you commit money.
And be skeptical of any itinerary, including this one, that fills every day. The best hours in Vietnam tend to be unplanned: a coffee that turns into an afternoon, a bus that stops somewhere better than where it was going. Leave room for those.
