How Long Do These Transfers Actually Take? We Checked Against Trips We Ran

Look up how long it takes to get from Hanoi to Ha Long Bay and you will be told three and a half hours. Or four. Both numbers are in circulation, both come from people who have made the trip, and the gap between them is not traffic.
We went back through our own itineraries to find out. Not route planners, not estimates. The schedules from groups we actually operated, with the departure and arrival times somebody wrote down on the day. Some of what came back was reassuring. Some of it corrected us.
The Ha Long number depends on the pier, not the distance
This is the one worth knowing before you book anything in northern Vietnam.
Ha Long Bay has more than one place to board a boat. The pier most itineraries use sits past Ha Long city, and from a Hanoi hotel that is a four hour morning. We know it is four because the same pair of times appears across six of our own documents: leave at half eight, board at half twelve. Three of those were groups that ran.
Lan Ha Bay sits immediately to the south and boards from its own pier. From the same Hanoi hotels that is closer to two and a half or three hours. Same limestone, same water, roughly an hour of your day between them.
So a quoted transfer time to "Ha Long Bay" is really telling you which pier. If your schedule has you boarding at noon, you have spent the morning. If it has you aboard by half eleven, someone made a different choice.
Vietnam, leg by leg
These are the corridors we run often enough to be confident about.
| Leg | Mode | Real time |
|---|---|---|
| Hanoi to Ha Long Bay (main pier) | Road | About 4 hours |
| Hanoi to Lan Ha Bay pier | Road | About 2.5 to 3 hours |
| Hanoi to Sapa | Road | 5 to 6 hours, with two short stops |
| Da Nang airport to Hoi An | Road | 30 to 40 minutes |
| Hue to Da Nang | Train | Roughly 2 hours 45 to 3 hours 35, depending on the service |
| Ho Chi Minh City to My Tho | Road | About 2 hours for 70 km |
| Chau Doc to Phnom Penh | Speedboat | About 5.5 hours |
Two of those deserve a note.
Hanoi to Sapa is a genuine half day and the two stops are not padding. On a five to six hour mountain road they are the difference between arriving fresh and arriving grey. Anyone quoting you five hours flat has not built them in.

The Hue to Da Nang rail times move because the trains are genuinely different. The tourist service and the scheduled one take different amounts of time over the same track, and the slower one is the nicer ride. That is a real choice, not a discrepancy.
Northern Thailand is a chain of short drives
The Thai north reads as a big loop on a map and travels as a series of manageable hops. That shape matters more than any single number.
| Leg | Mode | Real time |
|---|---|---|
| Bangkok to Kanchanaburi | Road | About 1.5 hours |
| Kanchanaburi to Ayutthaya | Road | 3.5 to 4 hours |
| Ayutthaya to Phitsanulok | Road | About 4.5 hours |
| Phitsanulok to Sukhothai | Road | About 1.5 hours |
| Sukhothai to Lampang | Road | About 3 hours |
| Lampang to Chiang Rai | Road | About 4.5 hours |
| Chiang Rai to Chiang Mai | Road | About 3.5 hours |
| Golden Triangle to Chiang Rai airport | Road | About 1 hour for 60 km |
The longest single leg there is four and a half hours. Nothing in the chain is a punishing day on its own, and that is the whole reason the region works overland. Fly into Chiang Mai and you skip all of it, which is a fair trade for a short trip and a real loss on a longer one.

We are more confident about the Vietnam numbers than the Thai ones, and it is only honest to say why. Our Vietnamese itineraries are written as hour by hour schedules, so the times are recorded as a matter of course. Our Thai ones are written as descriptions of the day. The drives get named and often do not get timed.
Why the published number and the real number disagree
Three things, and none of them is anybody lying.
The first is loading. A road time starts when the vehicle moves. A transfer starts when the first person comes down to the lobby. For a group that is fifteen to twenty minutes before anything has happened.
The second is stops. Long legs need them, and a good operator plans them in. Our Sapa run has two. They are not slack in the schedule, they are the reason people arrive able to enjoy the afternoon.
The third is the one that catches people out. Some legs are a drive and some are a day, and both get quoted in hours. Hue to Hoi An is about three hours if you simply drive it. Very few people simply drive it, because the road climbs a mountain pass with the coast open below it most of the way. Quoted as three hours it sounds like an afternoon. Run properly it is most of a day, and the day is the point.
If you take one habit from this article, take that one. When you see a transfer time on an itinerary, ask whether it is the driving time or the day.
What we do not publish
A fair question, since we have just published a table of our own operating times.
Times are facts about roads. Anybody with a vehicle and a year could measure them, and travellers are better served knowing them. What we keep is the design: the order we run these legs in, where we place the overnight stops, how hard we push any given day, and which pier we choose for which kind of group. That is judgement built over many departures, and it is what partners are actually buying.
So the numbers above are yours. The itinerary that arranges them is the work.
How we help partners
Send us a route and we will tell you where the time actually goes. Frequently the fix is not a faster transfer but a different one, or the same drive moved to a different day so it stops being dead time.
Partners stay the client facing brand throughout. We are the destination management company operating the ground, in both countries, on one contract. Start with our experiences or destinations pages, or send an outline brief and we will come back with a shape.
For the bigger picture on moving between the two countries, see our guide to travelling between Thailand and Vietnam, and for how many nights any of this needs, how many days you need.
FAQ
How long does it take to get from Hanoi to Ha Long Bay?
About four hours to the main pier past Ha Long city, door to door from a Hanoi hotel. A departure at half past eight typically boards at half past twelve. If your boat leaves from the Lan Ha Bay pier immediately to the south, the same journey is closer to two and a half or three hours. The distance is similar. The pier is what changes the number.
How long is the drive from Da Nang to Hoi An?
Thirty to forty minutes. It is one of the most predictable transfers in Vietnam and it rarely surprises anybody, which is part of why so many itineraries fly into Da Nang and sleep in Hoi An.
How long does it take to drive from Hanoi to Sapa?
Five to six hours by road, including two short stops of fifteen to twenty minutes. The stops matter on a mountain route of that length. A quote of five hours flat has probably not accounted for them.
How long is the transfer from Hue to Hoi An?
About three hours if you drive it directly. In practice most itineraries run it as a full day, because the road crosses the Hai Van Pass and the coastal views are among the best in Vietnam. Both answers are honest. They describe different products, so it is worth asking which one you have been quoted.
How long does it take to drive from Bangkok to Chiang Mai?
Most itineraries do not drive it. Bangkok to Chiang Mai is normally flown, at roughly an hour and a quarter in the air. Done overland through Ayutthaya, Sukhothai and Lampang it becomes several days of travel, not a single transfer, and it is worth doing only if the places along the way are the reason for going.
Are these times reliable in traffic?
They already include normal conditions, because they come from schedules that ran. The exceptions are Vietnamese public holidays and the roads into Hanoi's airport, where local advice is consistently to allow extra time. For anything time critical, such as an international departure, we build in a buffer beyond the times listed here.
