Laos rewards a slower trip than its neighbours. There's no coastline and no single "must-see" city pulling every itinerary the same way, so how many days you have decides more of your route here than in Thailand or Vietnam. The Laos-China Railway has also changed the maths: the Vientiane to Luang Prabang leg that used to be a whole day on a bus now takes about two hours, so even a short trip can cover real ground.
This guide sets out what fits at each length, by region and by interest, then compares every route side by side. For the places themselves, start with our Laos travel guide.
How long do you need in Laos?
| Length | What fits without rushing | Region mix |
|---|---|---|
| 1 week | The north's three main stops, using the railway between them | Luang Prabang, Vang Vieng, Vientiane |
| 10 days | The north plus a slower add-on, either Nong Khiaw or the Mekong slow boat in | North, plus Nong Khiaw or the Huay Xai boat |
| 2 weeks | The north unhurried, or the north combined with a first stop in northern Thailand | Northern Thailand plus Laos, or the north at a relaxed pace |
| 3 weeks | The north plus the south, since they don't share a fast road or rail link | North and south, usually joined at Vientiane |
| 1 month | The whole country at an easy pace, or Laos as one leg of a longer trip | Everything, or Laos plus Thailand and Vietnam |
Choose by length
1 week
Seven days is enough for the north's three big stops if you use the railway rather than the road: three nights in Luang Prabang, two in Vang Vieng and one or two in Vientiane, with a fast train replacing what used to be a long bus ride.
Luang Prabang, Vang Vieng and Vientiane by the Laos-China Railway
Three nights in Luang Prabang for temples and waterfalls, then a fast train on to Vang Vieng and Vientiane.
Best for Temples, easy trains, a settled pace
The Mekong slow boat into Luang Prabang, then the railway on
An unhurried river crossing from the Thai border, with the rest of the week for Luang Prabang and Vang Vieng.
Best for A scenic overland arrival from Thailand
See the full 1-week Laos itinerary for the day-by-day.
10 days
Ten days lets you add one thing to the week above. Nong Khiaw, a small riverside town under limestone cliffs, is the popular choice; the Mekong slow boat from northern Thailand is the other, though read the note on Bokeo province further down before you commit to that route.
Luang Prabang, Vang Vieng and Vientiane, extended north to Nong Khiaw
The 1-week route above with a detour north to Nong Khiaw's cliffs and the Nam Ou river before doubling back to Luang Prabang.
Best for Karst river scenery, a slower pace
The Mekong slow boat, then the north
The full two-day boat from the Thai border, then Luang Prabang, Vang Vieng and Vientiane at a relaxed pace.
Best for Arriving overland, without rushing the north
See the full 10-day Laos itinerary for the day-by-day.
2 weeks
Two weeks fits the north at an easy pace, with time for both Nong Khiaw and extra nights in Vang Vieng. It's also the length that makes sense if you're combining Laos with a first stop in northern Thailand, since Chiang Mai and Chiang Rai sit close to the border.
Northern Thailand into Laos
Chiang Mai and Chiang Rai first, then a flight or the Mekong slow boat into Luang Prabang, Vang Vieng and Vientiane.
Best for Two countries, no long bus days
Luang Prabang, Vang Vieng and Vientiane, unhurried
The same three stops as the 1-week route, with Nong Khiaw added and extra time everywhere else.
Best for A relaxed northern pace
See the full 2-week Laos itinerary for the day-by-day.
3 weeks
Three weeks is where the south comes in. The honest way to plan this is as two shorter trips joined at Vientiane: around ten days in the north, then a bus south to Thakhek for the loop's limestone valleys and Kong Lor Cave, on to Pakse, and out to the river islands of the 4,000 Islands near the Cambodian border.
Luang Prabang, Vang Vieng and Vientiane, then the Thakhek Loop
The northern route above, then a multi-day motorbike loop from Vientiane through karst valleys to Kong Lor Cave.
Best for Riding, caves, a wilder Laos
The north, then southern Laos in full
The northern route above, then Pakse, the Bolaven Plateau's coffee farms and waterfalls, and a proper stay on the 4,000 Islands.
Best for Coffee, waterfalls, slow river islands
See the full 3-week Laos itinerary for the day-by-day.
1 month
A month is enough to see the whole country without rushing, with slow days built in for the travel between north and south that the railway can't help with. It's also long enough to make Laos the middle leg of a bigger trip, crossing in from northern Thailand and out to Vietnam.
The whole country, north to south
The north, the Thakhek Loop and the far south, joined by buses and the railway where it reaches.
Best for Seeing all of Laos properly
Laos as the middle leg of a Southeast Asia trip
Northern Thailand first, then Laos north to south, before crossing on towards Vietnam or Cambodia.
Best for Thailand, Laos and onward in one trip
See the full 1-month Laos itinerary for the day-by-day, and remember the visa: both the e-visa and the visa on arrival give 30 days, so a month-long trip runs right up against that limit. See our Laos visa guide for extensions.
Choose by region
The north: Luang Prabang, Nong Khiaw and Luang Namtha. Almost every Laos itinerary starts in Luang Prabang, the UNESCO-listed town where the Mekong and Nam Khan rivers meet, and it's the natural base for Kuang Si Falls, the morning alms and a boat to the Pak Ou caves. See the Luang Prabang guide for how long to spend there and what to do.
The centre: Vang Vieng and Vientiane. Vang Vieng, about an hour by train from Vientiane and a little more from Luang Prabang, is where most people spend a couple of nights kayaking the Nam Song, swimming in the Blue Lagoons and climbing to a limestone viewpoint. Vientiane, the capital, is small and easy, and the jumping-off point for both the sleeper train to Bangkok and the road south. See the Vang Vieng guide and the Vientiane guide.
The south: Pakse, the Bolaven Plateau and the 4,000 Islands. The south gets far fewer visitors than the north, which is most of its appeal: cooler air and coffee farms on the plateau, then the Mekong widening into a scatter of river islands near the Cambodian border. See the southern Laos itinerary and the 4,000 Islands guide.
Choose by interest
- Temples and culture: the old town, the morning alms and the Royal Palace Museum in Luang Prabang.
- Rivers, caves and riding: kayaking and the water cave in Vang Vieng, and Kong Lor Cave on the Thakhek Loop.
- Coffee and waterfalls: the Bolaven Plateau, part of the southern Laos itinerary.
- Slow river islands: cycling between Don Det and Don Khon in the 4,000 Islands.
- Food: laap, or lam and sticky rice, covered in our Lao food guide.
- Festivals: Pi Mai Lao and Boun That Luang, covered in our Laos festival calendar.

Getting around: the railway, the slow boat and the road
The Laos-China Railway is what makes a short northern itinerary realistic: fast trains link Vientiane, Vang Vieng and Luang Prabang in about two hours end to end, with several a day, and a 2nd-class ticket from Vientiane to Luang Prabang currently costs about 360,000 kip. Domestic tickets are released only a few days ahead (reports say 3 to 7) and are sold on the LCR Ticket app, at stations and town ticket offices, or through resellers, and it's worth booking as soon as sales open in high season. It doesn't reach the south, so anything below Vientiane still means a bus or a minivan.
The classic slow boat from Huay Xai, on the Thai border, to Luang Prabang still runs, taking two days on the Mekong with a night in Pakbeng. Before you build a trip around it, know that Huay Xai sits in Bokeo province, where Canada advises avoiding 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, which is also why our own Northern Thailand & Laos trip now flies from Chiang Mai to Luang Prabang instead. Full fares, timetables and the current safety advice are in our Laos visa guide and Laos travel guide.
Prefer to travel with a group?
If you'd rather not plan the trains, the visas and the border crossings yourself, we run small-group trips across the routes above for solo travellers aged 18 to 40. I host every departure in person as your Trip Host, and in Laos a licensed local agency and licensed local guides run the ground arrangements. Compare every length on our Laos group trips page.
