Chiang Mai to Luang Prabang

Day one is the road. Chiang Khong is about 280 km from Chiang Mai, and the buses and package vans leave in the morning and arrive in the late afternoon, too late for that day's boat. You sleep in Chiang Khong, or cross the river that evening and sleep in Huay Xai, which puts you closer to the pier. Some package vans from Chiang Mai stop at the White Temple in Chiang Rai on the way.

Day two starts at the border. You clear Thai exit at Chiang Khong, take the shuttle bus across Friendship Bridge IV for about ฿25–30, and get your Lao visa on the far side. A tuk-tuk takes you to the slow boat pier, about 3 km north of central Huay Xai. The boat leaves around 10:30 to 11:00, so arrive by 10:00 if you want a seat, and buy the ticket at the pier office or through your guesthouse. It's a long wooden boat with old car seats or benches and a small snack counter on board, and it reaches Pakbeng after 6 to 8 hours, around dusk.

Pakbeng is a village that lives on the boat. Guesthouses meet every arrival and rooms cost about 120,000 to 250,000 kip, so there's no need to book one on the boat. Day three leaves Pakbeng around 08:30 to 09:30 and takes 6 to 7 hours to Luang Prabang's slow boat pier, about 8 km north of town, where tuk-tuks into the center charge a set 40,000 kip a person.

Bring water, food for both days, a jacket for the cold mornings on the river, and enough cash for three days, because Pakbeng has few ATMs. In peak season the boats fill, and a January 2026 review on 12Go describes two boats' passengers squeezed onto one on the second day. The UK government warns that Mekong travel can be dangerous with changing water levels and that boat safety standards vary, which is why I'd skip the speedboats that cover the same stretch in about six hours.

A package buys you the logistics, not a better boat. For about ฿2,666–2,890, a Chiang Mai agency or 12Go puts you in a van to the border, books the first night's room, takes you across the bridge and hands you a boat ticket. You still ride the same public slow boat, and the visa, food and usually the Pakbeng room are on top. It's the easy choice if this is your first land border.

Doing it yourself costs a little less and gives you the choice of where to sleep. Take the Green Bus Express from Chiang Mai's Terminal 3 at 09:30, about seven hours to Chiang Khong for about ฿380–390 (VIP is about ฿550), then a tuk-tuk to the bridge the next morning. Travelers who did it in 2025 put the whole trip from Chiang Mai at about US$120 with the visa and two nights' rooms.

Smaller boats run the same two days with cushioned seats, lunch, a guide and stops at villages and the Pak Ou caves before Luang Prabang. Nagi of Mekong leaves Huay Xai on Sundays, Wednesdays and Fridays and costs US$160 a person with a standard Pakbeng hotel, US$195 with one of the better lodges, or ฿4,900 for the boat alone, with pickup in Chiang Khong or Huay Xai. Shompoo runs a similar trip for about US$207–230. The visa is extra on both. I'd pick one of these if the public boat's crowds and long days on a bench put you off, because it's the same river either way.

Lao Airlines is the only airline with a nonstop flight, a flight that leaves Chiang Mai around 15:00 and lands in Luang Prabang about 50 minutes later. In the cool season it flies daily, and in the rest of the year about four days a week, so check the days before you plan around it. Booking sites show Thai AirAsia, Nok Air, Thai Lion Air, Thai Vietjet and Bangkok Airways on this route too, but those are connections through Bangkok that take four and a half hours or more. Luang Prabang airport is about 4 km from the center, and you can get a Lao visa on arrival there or use the e-visa.

The overland bus is a van from Chiang Mai to the border, then a Lao sleeper bus from Huay Xai through the mountains of Luang Namtha and Oudomxay. On 12Go the tickets leave Chiang Mai around 09:00 for about ฿1,450–2,430 and arrive the next morning, 22 to 24 hours later. Reviews from 2026 tell a harder story, with one 23-hour trip that was meant to arrive at 09:00 and arrived at 15:30, another that took almost 30 hours, and several about rough roads and little sleep. It's the cheapest way to reach Luang Prabang in one go, and the one I'd avoid.

There's a faster land option on the Lao side. Some Huay Xai agencies sell a van to Na Teuy station, three to four hours, and the Laos–China railway on to Luang Prabang in about two more, about US$25–35 in all. That gets you there the day after you cross, without a night bus, but a May 2026 review describes a cramped minivan with broken suspension, so expect a tight ride.

Chiang Rai is about 106 km from Chiang Khong, two hours closer than Chiang Mai, so the trip to Luang Prabang takes two days from there instead of three. The first public bus is too late for the morning boat, so you'd take a 05:00 package van or ride to the border the afternoon before, and a van and the Laos–China train get you to Luang Prabang the same day. Our Chiang Rai to Luang Prabang guide has the times and fares, and the Green Bus from Chiang Mai to Chiang Rai takes three and a half hours.

Most nationalities need a visa for Laos, and the Lao tourist visa gives 30 days. At Friendship Bridge IV you can get it on arrival, about US$40 in cash for most passports in 2026 or ฿1,600, plus a small immigration fee, with one passport photo and a passport valid for six months with two blank pages. Bring clean, uncreased US dollar notes, because worn ones get refused. The other way is the official Lao e-visa at laoevisa.gov.la, single entry for 30 days, processed in about three working days, which is accepted at Friendship Bridge IV and at Luang Prabang airport. Use the official site only.

Coming back into Thailand, you get the 30-day visa-exempt stay again if your passport is on the list, but entries by land on the exemption are capped at two a calendar year, and the officer can ask for an onward ticket. Crossing to Laos and back is not a guaranteed way to reset your stay. Our Thailand visa guide has the current rules.

The quickest way back is the Lao Airlines nonstop, leaving Luang Prabang around 13:00 to 13:30 and landing in Chiang Mai about an hour later. Overland, the slow boat runs upstream from Luang Prabang at 08:30 and reaches Huay Xai around 17:30 to 18:00 on the second day, so you sleep at the border, file a fresh TDAC and take the morning Green Bus from Chiang Khong. The night buses take 22 to 25 hours. Our Luang Prabang to Chiang Mai guide has the times, fares and Thai re-entry rules.
