Three weeks in Vietnam, and what the extra week actually buys
On this page
Three weeks in Vietnam is not a longer version of two weeks. It is two weeks with the things two weeks forces you to skip put back in.
Is three weeks enough for Vietnam?
Three weeks is where the country stops feeling rushed. Two weeks covers north, centre and south at a pace that works but never pauses. The third week buys either Ha Giang or the far south, and a real rest day in each region.
The rest day matters more than the extra place. A rest day is not a wasted day on a trip this long.
What does the route look like?
North to south, with the long hops flown and the short ones on the ground. The shape below is 21 days including both travel days.
Days 1-5, the north. Hanoi for two, then Ninh Binh and Ha Long Bay. This is the five-day northern trip almost exactly.
Days 6-9, Ha Giang. The loop, four days of riding or being ridden, with a night bus at each end. The four-day version is the detail, and the permit is not optional since June 2026.
Days 10-13, the centre. Fly Hanoi to Hue or Da Nang. Hue for the citadel and the tombs, the Hai Van pass, then Hoi An for two nights.
Days 14-16, the middle south. Either Da Lat for the highlands and the cool, or Quy Nhon and Nha Trang for the coast. This is the stretch most two-week trips lose.
Days 17-21, the south. Ho Chi Minh City for three, the Mekong Delta for two, and out. Or swap the delta for Phu Quoc if the trip needs to end on a beach.
| Stretch | Days | Getting there | Best months |
|---|---|---|---|
| Hanoi and the karst | 5 | Land at Noi Bai | Oct-Nov, Mar-Apr |
| Ha Giang loop | 4 | Night bus from Hanoi | Sep-Nov, Mar-May |
| Hue and Hoi An | 4 | Fly Hanoi to Da Nang | Feb-Aug |
| Highlands or coast | 3 | Bus or short flight | Varies by choice |
| Saigon and the Mekong | 5 | Fly, out of Tan Son Nhat | Dec-Mar |
Should you go north to south, or the other way?
North to south, for most dates. The weather generally improves as you travel down, and it puts Ha Giang early while you still have the appetite for four days on a motorbike.
The exception is October to December. The central coast is at its wettest then, and Hoi An floods most years in that window. Running south to north can put the centre later, by which time the rain has often eased. The month-by-month guide has the regional detail, because Vietnam does not have one season at a time.
What does the extra week actually buy?
Two things, and it is worth being clear which one you want.
The first is a place: Ha Giang, or the far south, or the highlands. Any of those is a real addition that two weeks cannot hold.
The second is pace. On a three-week trip you can spend three nights somewhere instead of two, which is the difference between seeing a town and being in it. Most people who have done both say the pace mattered more than the extra destination.
How do you get between the regions?
Fly the long hops and take the ground for the short ones. Hanoi to Da Nang and Da Nang to Saigon are both about an hour and cheap, and each saves the better part of a day.
Between Hue and Hoi An, and between Saigon and the delta, the road or the rail is better than the air. The train is worth doing in one leg on a trip this long — the Hue to Da Nang stretch over the Hai Van pass is the one to pick. The transport guide covers the rest.
What does three weeks in Vietnam cost?
Roughly 1,000 to 2,200 US dollars per person on the ground, excluding the flight in. Accommodation decides where inside that range you land, as it does on every length of trip here.
Three domestic flights is the usual number on this route, and they are a small line rather than a large one. The cost guide sets out the daily figures the total is built from.
What should you cut if the trip shrinks?
Ha Giang or the far south, and nothing else. Both are self-contained: removing either leaves the rest of the route intact and turns three weeks into the standard two-week trip.
What you should not cut is the rest days. Trimming those first is how a long trip turns into a fast one, which defeats the reason for taking three weeks in Vietnam in the first place.
If you have already done this route once, Vietnam off the beaten track is the second-trip version: Ba Be, Cao Bang, Ly Son and Phan Rang, and none of the famous stops.
FAQ
Is three weeks enough for Vietnam?
Three weeks is the length at which Vietnam stops feeling rushed. Two weeks covers the north, the centre and the south at a brisk pace. The third week buys Ha Giang or the far south, plus a genuine rest day in each region rather than a change of hotel.
What is the best three week itinerary in Vietnam?
North to south: five days around Hanoi, four in Ha Giang, four in the centre between Hue and Hoi An, three on the coast or in the highlands, and four in the south for Saigon and the Mekong. Fly the long hops and take the train for the short ones.
Should you travel Vietnam north to south or south to north?
North to south for most dates, because the weather usually improves as you go. It also puts Ha Giang early, while your legs and patience are fresh. The exception is October to December, when the central coast is at its wettest and running the other way can dodge it.
How much does three weeks in Vietnam cost?
Roughly 1,000 to 2,200 US dollars per person on the ground, excluding international flights. Accommodation is the line that decides it: guesthouses keep the total near the bottom of that range and three-star hotels push it towards the top.
Do you need more than one visa for three weeks in Vietnam?
No. The standard e-visa is valid for 90 days and 21 days fits comfortably inside it. Some nationalities have a 45-day exemption instead, which also covers three weeks. Only trips over the exemption length need an extension.
What should you cut if three weeks becomes two?
Ha Giang, which is six days door to door, or the far south. Cutting one of them turns this into the standard two-week route without breaking the shape of the rest.
