Ho Chi Minh City Bangkok overland
Ho Chi Minh City to Bangkok is a rail journey for part of its length and an honest slog for the rest: 7 legs (2 on rails, 1 by sea, 4 by road) across 3 countries, with 2 frontiers in between. It is 3 days if every connection is there when you reach it, and up to 6 if you arrive the day after one — the difference is waiting for a service that does not run daily, not travelling. The one to watch: Phnom Penh to Siem Reap is not a service we can stand behind. It is possible, and that is about the strongest thing to say for it. If the point is the journey, ask for a different pair of endpoints.
Stations that catch people out
- Siem Reap Angkor has no railway. The nearest railhead is Sisophon, about two hours away by road.
- Hua Lamphong Now mostly local services, but some eastern trains (Aranyaprathet) still start here.
- Krung Thep Aphiwat Bangkok's long-distance terminal since 2023 — not the old Hua Lamphong. Confirm which terminal your specific train uses.
Other ways round
The recommendation is what this planner would do with no further information. These are the genuinely different journeys between the same two points — not the same route with a station moved, which is why there are two of them and not ten. This page is written around the recommended one; open another in the planner to get its own crossings, nights and costs.

The route
Durations are typical scheduled running times, not departures, and the figure under each service is how often it runs — the number that decides whether a missed connection costs you an hour or a day. Where a last departure is shown it is the one worth setting an alarm for. No planner in this region can give you a departure time you should trust: the operators publish nothing in common. Take these legs to the booking sites below and read the real clock there.

What stops running, and when
Not a timetable — this planner will not print a departure time it cannot stand behind, and no two operators here publish in a way that would let it. This is the other half of the question, and the half that strands people: which legs stop for the day, and how late. Nobody misses a connection for want of knowing the 14:05 existed. They miss it because the last boat went at 17:00.
Plan backwards from the 07:30 Phnom Penh to Siem Reap — it is the earliest door to close on this route.
| Leg | Runs | Last |
|---|---|---|
| Phnom Penh Siem Reap Tonlé Sap fast boat | one departure in the morning, and only when the lake is high | 07:30 |
| Aranyaprathet Hua Lamphong Ordinary 275/279 | one each way, morning and afternoon — miss it and it is a bus | 13:00 |
| Hua Lamphong Krung Thep Aphiwat MRT Blue Line, 2 stops | roughly 06:00 to midnight | — |
Day by day
Shape, not a timetable. This is built from running times, the connection buffers above and your chosen pace — it deliberately states no departure time, because none of these operators publish one this page could stand behind. Use it to decide how many nights to book and where; use the operator sites for the clock.
- Ho Chi Minh City Phnom Penh Giant Ibis / Mekong Express coach 7h
- Phnom Penh Siem Reap Tonlé Sap fast boat 6h
- Siem Reap Sisophon Bus / shared taxi 2h
- Sisophon Poipet Royal Railway northern line 1h
- Poipet Aranyaprathet Tuk-tuk / on foot through the border complex 30m

Where you sleep
Priced where the journey actually stops, not averaged across the region — the difference between a night in Siem Reap and a night in Singapore is a factor of five, and it is worth seeing before you book. Figures are indicative low-season rates for a room booked a week or two out; the totals below use the simple private room band.

A casino border town. If you can reach Battambang or Sisophon instead, do — it is a better night in every way.
Border crossings
Itineraries die at frontiers, not on track. Never plan one of these without checking the current position for your own passport.
Bavet ↔ Moc Bai
Cambodia ↔ Vietnam- Where
- Road border — the coach handles the paperwork
- On the train?
- Bus stops, everyone off and back on
- Luggage
- Yes
- Visa
- Vietnamese e-visa should be obtained in advance — land borders do not reliably issue on arrival.
- Cash on the far side
- Vietnamese dong for onward transport.
- Time cost
- About 90 minutes of formalities
The trap. There is no railway here and no prospect of one. Reputable operators (Giant Ibis, Mekong Express) handle the formalities as a group and are worth the small premium over local buses.
Aranyaprathet ↔ Poipet
Thailand ↔ Cambodia- Where
- Border complex between the two railheads, crossed on foot or by short tuk-tuk
- On the train?
- No — SRT terminates at Aranyaprathet, Royal Railway starts at Poipet
- Luggage
- Yes, carried across
- Visa
- Get the Cambodian e-visa in advance. It removes most of the friction and most of the scam surface.
- Cash on the far side
- US dollars in small notes — Cambodia runs on them, and border ATMs are unreliable.
- Time cost
- About 180 minutes of formalities
The trap. The region's most scam-prone crossing: fake "visa offices" positioned before the real one, inflated e-visa fees, invented "processing" charges. Use only the official immigration building and know the correct official fee before you arrive. Budget 2–3 hours end to end, more at weekends.
Verify. Verify whether a Royal Railway train runs at all on your arrival day, or plan a night in Poipet or Battambang.
Where this breaks
Ranked by what actually ends trips, not by probability. A missed last connection costs a day and an unplanned hotel; a missed afternoon connection costs an afternoon.
-
caution
Phnom Penh to Siem Reap is not a service we can stand behind
Only runs when the lake is high, roughly August to March, and it is a hot crowded six hours. People take it for the floating villages, not the comfort.
What to do. Verify it is running on your date before you build the rest of the itinerary around it.
-
caution
Sisophon to Poipet is not a service we can stand behind
Verify the train runs at all on your date — frequency is often weekends plus selected days.
What to do. Verify it is running on your date before you build the rest of the itinerary around it.
-
caution
Sisophon to Poipet does not run every day
This one goes 0–2 — selected days only — confirm the train runs on your date before anything else. The days and the cost above are running times and fares: they do not include waiting for the next departure, because that depends on which day you arrive. On a weekly service that wait can be most of a week, and it is the difference between the length of the journey and the length of the trip.
What to do. Find the sailing or departure date first and build the rest of the itinerary backwards from it, rather than planning the route and looking up this leg last.
-
caution
Aranyaprathet ↔ Poipet has a moving part
Verify whether a Royal Railway train runs at all on your arrival day, or plan a night in Poipet or Battambang.
What to do. Confirm the current position before you book anything that depends on it.
-
caution
Phnom Penh needs 4 hours, not a connection
Onward ferry reached by road transfer. A gap smaller than this is not a connection — it is a missed train with a plausible-looking timetable behind it.
What to do. Plan an overnight stop here rather than trying to make it in one day.
-
caution
Poipet needs 4 hours, not a connection
International border crossed on foot. A gap smaller than this is not a connection — it is a missed train with a plausible-looking timetable behind it.
What to do. Plan an overnight stop here rather than trying to make it in one day.
-
caution
Aranyaprathet needs 4 hours, not a connection
International border crossed on foot. A gap smaller than this is not a connection — it is a missed train with a plausible-looking timetable behind it.
What to do. Plan an overnight stop here rather than trying to make it in one day.
-
note
The Phnom Penh – Siem Reap boat is weather-dependent
Ferries are cancelled rather than delayed, and a cancellation costs a day rather than an afternoon.
What to do. Never make this crossing the only path to a fixed commitment. Leave a slack day between it and any flight home.
Booking sequence
Book in order of scarcity times window length, not in the order you travel. The shortest leg on the whole spine sells out first.

1
State Railway of Thailand
~90 days
Sleepers on trains 9/10 and the southern overnights sell out first.
The official e-ticket site. Foreign cards fail on it fairly often, and an aggregator is the usual fallback when they do.
Book with SRTdticket.railway.co.th -
2
Royal Railway Cambodia
Limited and short
Verify the train runs at all on your date before anything else.
Schedule changes are announced informally, often on Facebook rather than the site. Confirm the train runs on your date before you plan anything around it.

Sea legs
Mostly turn-up-and-go
Langkawi and Samui routes are worth pre-booking in season, the Mekong slow boat the day before you sail, and the Philippine RORO crossings not at all — they are grounded or they are running.
-
4
Road legs
Walk-up, except the long coaches
The Vientiane–Hanoi sleeper coach and the Sumatra runs are worth a day or two ahead.
Everything else on this route, in no particular hurry:
-
·
Giant Ibis
Handles the border formalities as a group and is worth the small premium over the local buses.
Book with Giant Ibisgiantibis.com -
·
Local transfer
Taxi, tuk-tuk, songthaew or minivan at the station. Agree the fare before you get in.
Pay on the spot -
·
Tonlé Sap boat
Sold through guesthouses and aggregators. Only runs when the lake is high, roughly August to March.
No bookable site of its own — try 12Go12go.asia -
·
Urban metro
Contactless or a stored-value card at the station. Nothing to plan.
Pay on the spot
Where an operator cannot be booked from abroad — the Laos–China Railway above all — an aggregator is the practical route in. They add a fee, and some sell tickets they do not yet hold and buy them when inventory opens, which is a genuine cancellation risk on a scarce sleeper. Prefer the operator wherever the operator actually works, which is most of the time.
No affiliate links on transport. Every booking link above goes straight to the operator or aggregator and earns this project nothing. The operator's own site is listed first because it is usually cheaper and always more reliable, not because of what it pays — that ordering is the most load-bearing judgement on this page and it is not for sale. Booking URLs were last reviewed 2026-07 and are not machine-checked — if one is dead, search the operator name rather than trusting a reseller that ranks well.
Where it does earn. The hotel links in “Where you sleep” and the insurance link below pay a commission, at no extra cost to you. They are marked as paid links. Nothing about them changes a route, a price, or the order of anything: no hotel is recommended over another and no leg is routed differently because of them.
Costs
| Transport, 7 legs | $63 |
| Accommodation, 2 nights — Phnom Penh $20, Poipet $18 | $38 |
| Total | $101 |
Against flying
3 days, $101, 7 legs versus a flight of roughly 1h 41m gate to gate at somewhere around $56–116. That fare band is estimated from the 747 km great-circle distance, not from live inventory — check it.
The plane wins on time and often on money. People take this route because the overland journey is the thing they want, not because it is efficient. If that is not you, fly — and there is no shame in the sleeper one way and the plane home.
If you have more time
Where the slow-travel value actually is — the detours that turn a transit into a trip.
Angkor, from Sisophon
+2 nights, ~$12Two hours by road from the railhead at Sisophon. Angkor has no railway and never will, so this road leg is the price of the single best reason to be in Cambodia.
Take the Mekong to Phnom Penh instead of the bus
+1 night, ~$35Coach to Châu Đốc, then a river boat up the Mekong with immigration on the riverbank at Vĩnh Xương. It is slower and dearer than the direct coach, and it is the only Vietnam–Cambodia crossing that is not a road.
