Planning

Trains, boats, roads — and when to just fly

What each mode is actually like across the four countries, with real journey times, real fares, and an honest account of where the road is the only option and where it is a mistake.

Rail, which has changed more than anything else

The Laos–China Railway

Opened in December 2021 and it is the single biggest change to travel in this region this century. Vientiane to Luang Prabang takes two hours against nine on the old road, and costs about USD 15 in second class. It runs on to Boten on the Chinese border. Booking opens seven days ahead, extended from four in July 2025, and in December and at Lao New Year that window matters.

The catch is the stations. Vientiane's is 14 kilometres from the centre and Luang Prabang's is 12 kilometres out, so add about 55 minutes of taxi across a journey. It is still overwhelmingly the right choice against both the road and the plane.

Bangkok to Vientiane

Train 133 leaves Bangkok Krung Thep Aphiwat at 20:25 and arrives at Vientiane Khamsavath at 09:05; 134 does the reverse. Twelve and a half hours, about 874 baht for a second-class air-conditioned lower berth, with a working dining car. Thai immigration on the platform at Nong Khai, Lao immigration at Khamsavath.

Vietnam's north–south line

Hanoi to Hue overnight, about thirteen hours in a four-berth soft sleeper, is a decent journey and better than it was a decade ago. Hanoi to Ho Chi Minh City is thirty-two hours and almost nobody should do it. Hanoi to Ninh Binh or Dong Hoi are short, useful hops.

Cambodia

There is a line from Phnom Penh to Sihanoukville and one towards Poipet, both slow and limited. For visitors it is not a serious option.

River, which is the region's oldest road

Journey	Time	Cost	Note
Huay Xai – Pak Beng – Luang Prabang	2 days downstream	About USD 23 public	Six hours a day. Three days upstream.
Phnom Penh – Chau Doc	5 hours	USD 38 - 45	Includes both immigration posts.
Nong Khiaw – Muang Ngoi	1 hour	USD 5 - 8	Longtail. The through service down the Nam Ou no longer runs.
Hanoi – Lan Ha Bay overnight boat	1 night	Included in our trips	Board at Got pier, not Tuan Chau.
Cai Rang floating market	2 hours	USD 8 - 15 per boat	Must be on the water by 05:45.

The Mekong speedboat we will not book

There is a speedboat between Huay Xai and Luang Prabang that does in six hours what the slow boat does in two days. It runs at around 60 km/h on a river full of rocks, passengers wear crash helmets, and the safety record is poor. If time is the constraint, fly.

The dams built on the Nam Ou between 2013 and 2021 ended the through boat from Nong Khiaw to Luang Prabang, and similar projects have changed several other routes. River travel in this region is contracting, which is part of why we build itineraries around the journeys that remain.

Road, and honest journey times

Almost every operator's itinerary understates driving times. These are ours, door to door, with a comfort stop, in normal conditions.

Route	Time	Note
Hanoi – Lan Ha Bay (Got pier)	2 hours 30 minutes	The expressway has transformed this.
Hanoi – Ha Giang town	6 hours	Improved a lot, still six hours.
Ha Giang town – Dong Van	5 hours 30 minutes	Mountain switchbacks throughout.
Hue – Hoi An over the Hai Van	4 hours with stops	The tunnel saves an hour and misses the point.
Ho Chi Minh City – Can Tho	3 hours 30 minutes
Siem Reap – Phnom Penh	6 hours	With the Sambor Prei Kuk stop.
Phnom Penh – Kampot	3 hours
Luang Prabang – Nong Khiaw	4 hours	Paved and slow.
Chiang Mai – Chiang Rai	3 hours 30 minutes with stops
Pakse – Four Thousand Islands	3 hours plus a boat

Laos is the country where road time is worst relative to distance: mountain roads, few of them, and no alternatives. Cambodia has the best trunk roads of the four for the money. Vietnam has excellent expressways in the lowlands and genuinely demanding mountain roads in the north.

When flying is the right answer

We are an overland operator and we still fly some legs, because there is a difference between a good travel day and a wasted one.

Bangkok to Siem Reap. Not a choice: the land border is closed. One hour.
Hanoi to Luang Prabang. The overland alternatives from northern Vietnam are slow and require an embassy-issued Lao visa. Ninety minutes in the air against two days and a paperwork problem.
Hanoi to Hue or Da Nang. Seventy minutes against thirteen hours on the train. The train is a pleasure once; twice is a waste of the trip.
Da Nang to Ho Chi Minh City. Eighty minutes against seventeen hours by rail. Nobody should take that train.
Vientiane to Pakse. The road is eleven hours.

And when it is not: Luang Prabang to Vientiane, where the train is better in every respect; anything under four hours by road, where the airport time eats the saving; and any leg where the flight schedule forces a 05:00 start to save two hours.

Local transport, for the hours you are on your own

Grab works in Vietnam, Thailand and Cambodia for cars and motorbikes, and it removes the negotiation. It does not work in Laos.
Tuk-tuks in Cambodia are cheap and best booked through the app; a street negotiation costs two to three times the app fare.
The Bangkok express boat is public transport at about 15 baht and the best sightseeing in the city.
Bicycles are the right way to move on Don Khon, in Hoi An and around Nong Khiaw.
Motorbike hire is available everywhere and excluded by most travel insurance without the correct licence. We do not arrange it.

Common questions

Questions travellers ask most

Is the Laos–China Railway bookable in advance from abroad?

Booking opens seven days ahead. Agents such as 12go and Bookaway sell it with a small markup and save you a station queue; the official channel needs a Lao phone number or a passport shown at a counter.

We book it for our travellers the moment the window opens.

Are night buses ever a good idea?

Rarely. They save a hotel night and cost you the following morning, and the sleeper buses in Laos and northern Vietnam have a poor safety record on mountain roads.

We do not use them. Night trains are a different matter and we use those.

How reliable are internal flights?

Vietnamese and Thai domestic services are broadly reliable. Lao Airlines is less so, and thin routes such as Hanoi–Luang Prabang are consolidated or retimed more often than we would like.

We build a buffer around any flight that connects to another flight, and we do not schedule a border crossing on the same day as an international flight.

Can I combine several of these journeys into one trip?

That is essentially what our routes are. The twenty-four-day four-country route uses a night train, a fast train, a night on a boat, four flights and about thirty hours of road.
