This is the boat everyone means when they say "the slow boat to Laos": a public riverboat down the Mekong from the Thai border to Luang Prabang, broken into two days by an overnight stop in a one-street river town that exists almost entirely to serve this crossing. It's a leg, not a trip in its own right. Most people reach it from a northern Thailand loop through Chiang Mai, Pai and Chiang Rai, then continue on into a longer Laos itinerary once they land in Luang Prabang. This page covers the boat itself: the border crossing that starts it, the two days on the river, and where it fits into a longer route.

Is this route for you?
This suits anyone arriving in Laos overland from northern Thailand who wants the river journey to be part of the trip rather than a chore to get past, and who's genuinely fine with a slow, quiet day on hard-ish bench seating and limited onboard entertainment. Bring a book, load music or podcasts before you leave phone signal, and treat the boredom as the point rather than a flaw.
It's a poor fit if you're short on time or don't do well with a long, unstructured day: budget two full travel days for it, not one, since there's no way to compress it safely on the standard public boat. If a scenic river crossing isn't the draw and you'd rather just get to Luang Prabang, flying is faster and isn't a lesser choice; our Laos itinerary guide sets out the other ways in.

Check your government's travel advice before you commit. Huay Xai is in Bokeo province, and as of September 2026 Canada advises against non-essential travel within 10 km of the Thai border there, the UK asks for extreme caution in Bokeo, and Germany advises against travel to Bokeo and Sainyabuli. Some travel insurance stops covering places your government advises against, so read your policy. Our Laos visa guide has the details.
Day by day
Chiang Rai to the border, then across into Laos
Huay Xai
Getting there bus from Chiang Rai's terminal to Chiang Khong, about 2 to 3 hours (Green Bus runs several services a day, roughly 65 to 100 baht); then a tuk-tuk from Chiang Khong town to the Thai border post, about 150 baht
- Morning
- the bus down from Chiang Rai
- Afternoon
- exit Thailand at the Chiang Khong checkpoint, cross the Friendship Bridge on the shuttle bus (20 baht by day, more at night and weekends), then complete Lao immigration at Huay Xai. Most nationalities can get a visa on arrival here in cash, with a passport photo; our Laos visa guide has the current fee by nationality. Once you're through, walk or tuk-tuk into Huay Xai town and buy your slow-boat ticket at the pier's own ticket office for the next morning
- Evening
- settle into Huay Xai for the night
Eat simple Lao-Thai border food, the first taste of sticky rice and jaew (chilli dip) for most travellers
Local tip carry US dollars in cash for the visa fee and small Thai baht notes for the tuk-tuk and bridge shuttle; there's no exchange counter at the border itself
Down the Mekong to the halfway stop
Pakbeng
Getting there the slow boat itself, leaving Huay Xai pier some time between 9am and 11am (double-check the exact time at the ticket office the day before); about 6 to 8 hours on the river
- Morning
- board at the pier and settle in for the day; seating on the standard public boat is a hard wooden or plastic bench, so a cushion or a rolled-up jacket helps
- Afternoon
- hours of jungle-lined banks, riverside villages on stilts and the occasional water buffalo herd, with a lunch or snack stop depending on the boat
- Evening
- arrive Pakbeng by early evening; the village is small and quiet, so it's an early night before the second day on the river
Eat a simple riverside Lao-Thai dinner; options in Pakbeng are basic but adequate
Local tip bring snacks, water and cash; Pakbeng has few or no ATMs
The Pak Ou Caves and arrival
Luang Prabang
Getting there re-board the same boat or operator, about 6 to 8 hours on the river's more scenic second half
- Morning
- depart Pakbeng
- Afternoon
- some operators stop at the Pak Ou Caves, two riverside limestone caves holding thousands of small Buddha images (otherwise a separate half-day trip from Luang Prabang itself)
- Evening
- arrive Luang Prabang by late afternoon or early evening
Eat your first Luang Prabang night-market dinner, sai oua (herb sausage) or or lam, the city's buffalo-skin and eggplant stew
Local tip the pier is a way out from the old town; agree a tuk-tuk fare before you get in, and have your Luang Prabang guesthouse sorted before you leave Pakbeng
Where this fits into a longer trip
At two to three days including the approach, the slow boat is too short to be a trip on its own. Almost everyone treats it as a connector: on the Thailand side, it's the natural way to finish a Chiang Mai, Pai and Chiang Rai loop and turn a Thailand-only trip into a combined Thailand and Laos one. On the Laos side, it's the classic overland opening to a longer route through Luang Prabang, Vang Vieng and beyond.
Laos in 1 week, arriving by the slow boat
Two days on the river from the Thai border to Luang Prabang, then the Laos-China Railway on to Vang Vieng for the rest of the week.
Best for A scenic overland arrival, then the railway
Laos in 10 days, the slow boat then the north
The same two-day river crossing, then Luang Prabang, Vang Vieng and Vientiane at a more relaxed pace than the 1-week version.
Best for The full northern loop with a river entry
If you'd rather see the Luang Prabang, Vang Vieng and Vientiane leg in more detail, see our dedicated route guide to that stretch.
What it costs
| Item | Typical price | About |
|---|---|---|
| Bus, Chiang Rai to Chiang Khong | 65 to 100 baht | Under £2, or under $3 |
| Tuk-tuk, Chiang Khong to the border | about 150 baht | About £3, or $4 |
| Friendship Bridge shuttle | 20 to 40 baht | Under £1, or under $1; more at night and weekends |
| Lao visa on arrival | about US$40 cash | See our Laos visa guide for the fee by nationality |
| Slow boat ticket, Huay Xai to Luang Prabang | 400,000 to 500,000 kip at the pier | About £14 to £18, or US$18 to $23 |
| Guesthouse room, Pakbeng | about 120,000 to 200,000 kip for a basic room found on arrival; US$19 to $42 for rooms listed online | About £4 to £7 for a basic room; £15 to £33 online |
| Simple riverside meal | 20,000 to 60,000 kip | Under £2, or under $3 |
At September 2026 rates, US$1 is about 22,400 kip and £1 is about 30,000 kip. Buying the boat ticket yourself at the Huay Xai pier is consistently cheaper than booking it through a guesthouse or agent in Luang Prabang or Chiang Mai, who commonly charge 600,000 kip or more for the same seat.
Getting there, away and around
Green Bus runs several daily services from Chiang Rai's bus terminal to Chiang Khong, about 2 to 3 hours. From Chiang Khong, a tuk-tuk covers the last stretch to the Thai border post. Once you're through Lao immigration at Huay Xai, the boat is the only realistic way to cover this stretch of river: there's no useful road or rail alternative that follows the same bank, which is exactly why the crossing takes two days rather than one. From Luang Prabang, the Laos-China Railway carries on to Vang Vieng and Vientiane in under two hours each, covered in our Laos visa guide.
The speedboat option
A faster speedboat covers the same stretch in about 6 hours, but it has a poor safety record on this river, so we don't recommend it.
A more comfortable, guided version
A couple of small-ship operators run the same two-day, one-night route in more comfort. Nagi of Mekong departs Huay Xai three times a week; Shompoo Cruise runs four times a week in the cool season and twice a week from May to September, with a stop at a riverside Khmu village. Both carry around 40 passengers, include a guide and lunch, and cost from about US$140 a person, with prices up to about US$250 or more depending on the booking site and your Pakbeng hotel, against the public boat's US$18 to $23. Both were still operating when we checked in September 2026.
Best time and festivals on this route
November to February is the best window: the cool, dry season gives the most settled water and the clearest river light for photos. Avoid May to October, when higher, faster water can make for a bumpier and sometimes slower ride, and treat March and April with some caution too, since low water levels can occasionally complicate navigation on some stretches, on top of the haze that affects northern Thailand and Laos alike in the burning season.
If your crossing lands in mid-April, you'll reach Luang Prabang in time for Lao New Year.
What to eat on this route
Expect simple Lao-Thai border food in Huay Xai and Pakbeng: sticky rice with jaew (a chilli dip), and a cold Beerlao on the boat as a low-key ritual by the second day. Save the bigger meal for Luang Prabang, where or lam (a buffalo-skin and eggplant stew) and sai oua (herb sausage) are the city's own dishes. Our Lao food guide covers the wider country.
If you'd rather do this with a small group, our Northern Thailand & Laos trip follows the same corridor from Chiang Rai into Laos, though it currently flies from Chiang Mai to Luang Prabang rather than crossing the river at Huay Xai, because of the government advice on Bokeo province, which can affect travel insurance cover; see our Laos visa guide for the current advice. For a Laos-only small-group trip that starts once you've reached Luang Prabang, see Laos Explorer, or browse all our Laos trips.
