Plan · Overland legs
Every leg, by time, comfort and cost
This is the table we plan from: each overland or river leg used in our journeys, with the mode, approximate time, how comfortable it is, its cost relative to the others, and the source and date we last checked.
How to read the table
- Time is approximate door-to-door on the vehicle, from the source listed. Border time is included where the source includes it.
- Comfort is our own judgement for an adult in reasonable health: High (you could read or sleep), Medium (fine for a day), Low (tiring; plan a rest after).
- Relative cost compares legs with each other, from $ (cheapest) to $$$$ (dearest). It is not a price.
- Checked is the date we last read the source. Timetables change between seasons and years; we confirm every leg with the operator before you travel.

The SE trains offer four-berth soft sleepers, six-berth hard sleepers and soft seats. Official timetables and tickets are on the Vietnam Railways ticketing site.

Arrange visas before you travel. Sources disagree on what each land post issues, and one source states that no visa on arrival is given at Lao Bao – Dansavanh. We do not plan any leg that depends on buying a visa at a border.

What the table tells you about fewer flights
Read across the comfort column and a pattern appears. The rail legs in Vietnam and the fast train in Laos are the most comfortable ways to cover their distance — more comfortable, door to door, than the equivalent flight with airport time added. The slow boat is uncomfortable on the public boat and pleasant on the premium one, and either way it is the reason to be there. The border roads are the hard part: low comfort, long hours, and no flight that replaces them.
That is how we place rest days. Every journey puts a day with nothing booked after the legs marked Low. See the pacing guide, the journeys, and the places they stop in.
Common questions
Questions travellers ask most
How old is this information?
Each row shows the date we last read the source. We re-check every leg against the operator when we book a trip.
Why do you use guidebooks and blogs as sources?
Because several of these operators do not publish timetables online. Where an official source exists, such as the Vietnam Railways ticketing site, we cite it.
Which leg do people find hardest?
The land border days: Hue into Laos, and the islands into Cambodia. Both are long and both need vehicles arranged on each side.
Is the slow boat safe?
It is a long-established passenger service. Sit away from the engine at the back, and keep your bag where you can see it.
