One month in Vietnam, and what the extra fortnight actually buys
On this page
Two weeks in Vietnam is a good trip that spends a lot of itself in transit. One month in Vietnam is the first length at which the country stops behaving like a corridor and starts behaving like a place, and the extra fortnight goes almost entirely into three things a shorter trip cannot reach.
Why is a month different?
Because of the shape of the country. Vietnam runs about 1,650 km end to end and roughly 50 km wide in the middle, so every itinerary is a line rather than a loop, and a fortnight spends several of its days on that line.
A month absorbs the travel instead of being defined by it. The same route with the same stops suddenly has room for the places that sit off the spine, and those are the ones people come back talking about.
What does the extra fortnight buy?
Three things, and they are worth naming precisely.
The Ha Giang loop is the first: four days of riding plus two travel nights from Hanoi, which is a sixth of a fortnight and a fifth of a month. It is the best road in the country and it does not fit two weeks without wrecking them.
Phong Nha is the second: two or three nights halfway up the country, for caves that range from a boat ride to an overnight underground.
The Mekong Delta as an overnight is the third. A day trip from Saigon cannot reach the dawn floating markets, because they trade at first light and finish by breakfast. Two nights in Can Tho can.
The month, in shape
Not a day-by-day plan, because a month does not want one. This is where the weeks go.
Week one: the north. Hanoi for three days, then the choice the northern week sets out — Sapa's valleys or Ha Long and Cat Ba. With a month you can have both.
Week two: Ha Giang. The loop and its travel nights. This is the week that only exists at this length.
Week three: the centre. Phong Nha, then Hue, Da Nang and Hoi An — the central five days with room to breathe rather than a schedule.
Week four: the south. Saigon, the delta with a night in Can Tho, and either an island or Da Lat to finish.
| Week | Where | Nights | What it adds over a fortnight |
|---|---|---|---|
| 1 | Hanoi, Sapa or Ha Long | 7 | Both rather than one |
| 2 | Ha Giang loop | 6 to 7 | The whole week |
| 3 | Phong Nha, Hue, Da Nang, Hoi An | 8 | Phong Nha, and unhurried days |
| 4 | Saigon, Mekong, an island or Da Lat | 7 | The delta overnight |
Which direction should you travel?
Whichever puts each region in its dry months. Vietnam's three regions keep different calendars, and a month is long enough that you will cross at least one seasonal boundary — the seasons guide is the thing to plan against rather than the map.
In practice most people fly into one end and out of the other, which avoids backtracking over 1,650 km. Open-jaw tickets into Hanoi and out of Saigon, or the reverse, usually cost the same as a return.
What does one month in Vietnam cost?
Less per day than a fortnight, in most cases. The expensive parts of a Vietnam trip are the international flight and the moving around, and a month amortises the first and slows the second.
A comfortable middle runs near 1,650,000 dong a day, about 65 US dollars, on the figures in the cost guide. A month at a slower pace, with fewer internal flights and longer stays, frequently comes in under that daily figure rather than over it.
What should you check before booking?
The visa length. Vietnam's e-visa is issued for a defined period, and a month-long trip sits close enough to the edge of the usual lengths that the dates are worth confirming on the official portal rather than assuming. The e-visa guide covers the application and the mistakes that get one refused.
The other thing is Tet. A month is long enough that a lunar new year can fall inside it, and that changes the trip considerably rather than slightly.
If a month turns out to be more than you have, three weeks keeps the shape of this route and drops one region rather than compressing all of them.
FAQ
Is one month too long for Vietnam?
No, and it is the first length at which the country stops being a transit schedule. Vietnam runs 1,650 km end to end and a fortnight spends much of itself moving. A month buys the Ha Giang loop, the caves at Phong Nha and the delta beyond a day trip, none of which fit comfortably into two weeks.
What can you do in a month in Vietnam that you cannot in two weeks?
Three things, mainly. The Ha Giang loop, which costs four days plus two travel nights. Phong Nha, which needs two or three nights of its own. And the Mekong Delta as an overnight rather than a day trip, which is the only way to reach the dawn markets.
Should you travel north to south or south to north?
Either, and the decision is usually the weather rather than the map. Vietnam's three regions run different calendars, so pick the direction that puts each region in its dry months. In practice most people fly into Hanoi and out of Saigon, or the reverse, and never backtrack.
How much does a month in Vietnam cost?
Roughly double a fortnight rather than more, because the expensive part of a trip is the international flight and the moving around, not the days. A comfortable middle sits near 1,650,000 dong a day, and a month at a slower pace often costs less per day than two weeks does.
Do you need a different visa for one month?
Check the length before you book. The Vietnam e-visa is issued for a defined period, and a month-long trip sits close enough to the edge of common visa lengths that the dates are worth confirming on the official portal rather than assumed.
