Who this journey is for

For travellers who want one country and to see all of it, north to south. Laos rewards slowness more than its neighbours: the towns are small, the river sets the pace, and the two-day slow boat is the main event rather than a transfer. The route is gentle — no single leg longer than the second day on the boat.

The journey starts in Huay Xai, the Lao river town where the slow boats leave. How you reach it is up to you; we advise on the options when you send the form.

The journey, leg by leg

Day 1

Huay Xai

Meet our local contact at your hotel. Buy snacks, a cushion and water for tomorrow. Early night.

Day 2

Slow boat, day one: Huay Xai to Pakbeng

A whole day with nothing to do but watch the river

The boat leaves around nine to half past nine and takes about six hours to Pakbeng. On the public boat the seats are old car seats, not bolted down, so arrive early. A premium boat is an option at a much higher price: modern seats, a meal and a stop at the Pak Ou caves on day two.

Day 3

Slow boat, day two: Pakbeng to Luang Prabang

About eight hours, the longer of the two days. You reach Luang Prabang in the late afternoon.

Days 4–7

Luang Prabang

Luang Prabang sits on a peninsula between the Mekong and the Nam Khan, and its mix of Lao temples and colonial houses is inscribed by UNESCO. Day 4 is free. Day 5 is a guided morning through the temples and the old streets; day 6 a car to the Kuang Si waterfall in the afternoon, when the light is softer; day 7 is a rest and laundry day. If you watch the dawn alms round, watch from across the street and keep quiet.

Days 8–9

Fast train to Vientiane

The Laos–China railway, open since December 2021, runs from Luang Prabang to Vientiane in about two hours on the fast trains. Two nights in the capital — the riverfront, That Luang, a slow lunch.

StayHotel in central Vientiane, 2 nightsMealsBreakfastsTravelTrain about 2 h, station transfersOn foot3–4 km

Day 10

Vientiane to Pakse

The one leg where we usually recommend flying. The alternative is a long overnight bus; we quote both and you choose. Either way you sleep in Pakse.

Days 11–12

Champasak and Vat Phou

A short drive south to Champasak. Vat Phou, the Khmer temple complex on the mountainside, is a morning visit: steep stone steps, a view across the plain, and the old processional axis down to the river.

Days 13–16

Si Phan Don

Road to the landing at Ban Nakasang, then fifteen to twenty minutes by boat to Don Det or Don Khon. Four nights in the islands: bicycles, the Li Phi falls, a boat to the Khone Phapheng falls, and long afternoons. This is the second laundry stop.

Common questions

Questions travellers ask most

Can we do the slow boat downstream only?

Downstream, Huay Xai to Luang Prabang, is the direction we plan. Upstream is slower and few travellers choose it.

Is the overnight bus to Pakse bearable?

For some people, yes. Sleeper buses are cramped for anyone tall. We quote the flight alongside so you can choose with the numbers in front of you.

Will we see dolphins in the islands?

No. The last Irrawaddy dolphin in the pool on the Lao–Cambodian border died in 2022. Cambodia's remaining river dolphins live further south, towards Kratie.

Can we start in Luang Prabang instead?

Yes, and drop the boat. But the boat is the reason this journey exists, so we would suggest a different one.

A longtail boat glides across a lake toward towering limestone karsts covered in dense jungle.
