The distance problem
Vietnam looks compact on a phone screen and is not. The north to south railway runs 1,726 km and an end to end journey takes about 30 hours. That single figure settles most itinerary arguments: you are not seeing Hanoi, Hue, Hoi An, Da Lat and the Mekong in a week without spending the week in seats.
The fix is not to move faster. It is to move less.
Seven days
Pick two bases and let each earn its keep.
- Hanoi and the north. The Old Quarter, a night on the water at Ha Long or Lan Ha, and a day that is nothing but eating. Arrival logistics are in Hanoi airport to the Old Quarter.
- Or Da Nang and Hoi An. Beach, an old town that is genuinely old, and the Hai Van coast on the doorstep.
- Or Ho Chi Minh City and the Mekong. A city that does not stop and a delta that never hurried, with the shortest airport transfer in the country, covered in Tan Son Nhat to District 1.
One internal flight between two of those is fine. Two flights in seven days is a mistake you make once.
Ten days
Add the third base, and put the train leg in the middle. Hue to Da Nang takes under three hours and runs through three tunnels on the flank of the Hai Van pass, with the sea below and the highway far above. Book it in daylight. The full picture of the line is in the Reunification Express.
Fourteen days
Now the country opens up. North, centre and south with two or three nights in each, plus one of the places that needs a detour: Sapa, Phong Nha, Da Lat, Ninh Binh or Phu Quoc. This is also where overnight transport stops being a sacrifice, because losing a morning to a sleeper bus costs you a fourteenth of the trip rather than a seventh. How those work is in sleeper buses in Vietnam.
Let the season pick the half
The central coast is dry from January to August and in its typhoon and wet season from September to December. The north is cool and dry from December to February. The south is dry from December to April.
An October itinerary built around Hoi An boat trips is an argument with the weather that the weather wins. The full month by month picture, with a picker, is in when to go to Vietnam.
Book in this order
- Flights in and out, ideally into one city and out of another so you never backtrack.
- The fixed points: a boat night, a booked tour, anything with a date.
- The train leg, because the good seats on the good stretch go first.
- Everything else, loosely, once you are there.
That last line only works if your phone works. Sizing is in how much mobile data for Vietnam, the visa is in the Vietnam e-visa, and the plans are in the Vietnam eSIM store.
