Southeast Asia Backpacking Route: The Best Order

Last updated: 28 September 2026. Figures checked against the sources listed at the end of this article.

Draw almost any first-time Southeast Asia itinerary and the same flaw shows up. It is a list of places, not a sequence of borders. Hanoi, Ha Long Bay, Hoi An, Ho Chi Minh City, Phnom Penh, Siem Reap, Bangkok, Chiang Mai — it looks tidy on a map and it dissolves on the ground, because the slow, expensive and genuinely unpredictable parts of that trip are the crossings between countries, and a list of cities tells you nothing about them.

The order you travel in decides how much of your budget disappears into transport, how often you have to think about entry paperwork, and whether your last two weeks happen in monsoon rain. Get the direction right and the trip gets cheaper and calmer at the same time. Get it wrong and you spend the second half undoing the first.

Why the sequence matters more than the list

Three things change depending on the direction you travel.

Season moves across the region, not with it. Southeast Asia does not have one monsoon. The rain arrives in different places at different months, and a route running north to south will cross weather systems that a route running the other way meets in a different order. Two travellers on identical itineraries six weeks apart can have completely different trips.

Borders are the fixed costs. Everything inside a country is flexible: you can eat cheaper, move slower, sleep in a dorm. A border is not flexible. It has opening hours, paperwork and a direction, and it is the one part of the trip you cannot improvise at 6pm on a Sunday.

Overland distance is the real budget killer. Flights look cheap per booking and expensive per kilometre once you add airport transfers and a night lost to a red-eye. Overland legs look cheap per booking and expensive in days. The best route minimises backtracking, not ticket price.

The route, stage by stage

This is the sequence that avoids doubling back. It runs Vietnam north to south, crosses into Cambodia, continues into Thailand, and treats Laos as an optional loop rather than a mandatory leg.

Stage 1 — Northern Vietnam, southbound

Start in Hanoi. It is not the region’s largest aviation hub, and this route does not need it to be: what matters is that starting here puts you at the top of a corridor you can work down without ever reversing, and northern Vietnam is among the cheapest parts of the region to spend your first week while you find your rhythm. Every alternative start point forces you to double back at some stage.

Give northern Vietnam a week if you want the karst landscapes, less if you do not. The mistake here is booking too much in advance: this is the part of the trip where weather changes plans most often, and the cheapest accommodation is bought two or three days out, not two months.

Stage 2 — Central Vietnam, moving down the coast

Continue south. Central Vietnam is where most people slow down, and it is also where the gap between the country’s national price averages and what you actually pay is widest — coastal towns price for visitors.

This is the right place to spend your slack. If you fall behind schedule anywhere on this route, fall behind here rather than at the end.

Stage 3 — Southern Vietnam, then the Cambodian border

Finish Vietnam in Ho Chi Minh City. From here you cross into Cambodia by land, and this is the first stage where the sequence genuinely matters: the southern corridor is the busiest crossing between the two countries, and going overland from south Vietnam into Cambodia sets you up to move north through Cambodia and onward into Thailand without ever backtracking.

Before this border, not on the day: check the current entry requirements on your own government’s advisory. Do not rely on a blog post, including this one. The UK’s advice is at gov.uk/foreign-travel-advice and Canada’s at travel.gc.ca/travelling/advisories.

Stage 4 — Cambodia, northbound

Phnom Penh, then north to Siem Reap. This leg is short, and it is the one place on the route where a fixed date is worth committing to: the temple complex at Siem Reap is the most date-sensitive stop on the whole itinerary.

Buy your pass from the official operator, not from anyone who approaches you at the roadside — Angkor Enterprise is the government body that issues them, and its site is the only reliable place to confirm current prices, opening hours and exactly what a pass covers. Check it before you build a day around one temple, because not every site in the wider area is included in a standard pass and the details change. Budget two full days here, not one — a single day among those temples in that heat is a forced march.

Stage 5 — Into Thailand, then north

Read this before you plan the crossing, because it is the one stage where the correct advice has recently changed.

As of the UK Foreign, Commonwealth & Development Office travel advice current at 28 September 2026, the FCDO advises against all but essential travel to areas within 20km of Thailand’s land border with Cambodia, and states that “land borders and crossings between Thailand and Cambodia remain suspended.” Fighting occurred along parts of the border in 2025, and further clashes took place in early December involving rocket and artillery fire. Tourist sites close to the border are closed and there are unexploded landmines in the area.

So do not plan to enter Thailand overland from Cambodia. Fly. It is the duller answer and it is the correct one. Any itinerary — including earlier versions of this one — that treats that land crossing as a normal step is out of date.

Once you are in Bangkok you have a real decision, and it is the one most itineraries get wrong: north to Chiang Mai, or south to the islands.

Do not do both unless you have more than two months. Thailand is large, the two halves are in opposite directions from Bangkok, and attempting both turns the trip into a series of transport days. Pick one.

Stage 6 — Laos, as a loop, or not at all

Laos is the stage that ruins otherwise good routes. It sits between Vietnam, Cambodia, Thailand, Myanmar and China, and it is landlocked, which means every entry and exit is a border crossing.

Go only if you are going to commit. A fast loop in and out of northern Laos costs you more days in transit than the country is worth at speed. If you are short on time, cut Laos entirely and spend those days in Vietnam or Thailand — you will have a better trip.

Stage 7 — Onward

From Thailand you can fly out of Bangkok, or continue south towards Malaysia — but the overland option needs checking before you commit to it. The same FCDO advice current at 28 September 2026 advises against all but essential travel to Pattani, Yala and Narathiwat provinces and to the districts of Chana, Thepa, Na Thawi and Saba Yoi in southern Songkhla province. It also advises against all but essential travel on the Hat Yai to Padang Besar train line — which is precisely the overland corridor towards the Malaysian border. If your plan runs through there, start from the current FCDO regional risks page for Thailand rather than from any itinerary, including this one.

Decide this at the end, not the beginning. By the time you reach Bangkok you will know your actual daily spend rate, and that number — not the one you guessed before you left — is what should decide whether you keep going.

What the season actually does to this route

Southeast Asia does not have one monsoon, and the numbers make the point better than the platitude does. These are the average daily rainfall figures for the four cities on this route, calculated from 1,827 days of observations per city between 2020 and 2024.

Average millimetres of rain per day. Source: ERA5 reanalysis via Open-Meteo, daily observations 2020–2024.

Read it as millimetres per day, so 14.7 for Hanoi in September means it rains hard and often, while 0.5 in December means it barely rains at all.

Three things follow, and they change how you should sequence the trip.

Northern Vietnam has a real dry season, and the swing is dramatic. Hanoi goes from 14.7mm a day in September to 0.5mm in December. That is not a mild difference — it is the difference between a wet holiday and a dry one, and it is why the same itinerary can feel like two entirely different trips depending on the month you start.

The southern half of the route does not get that option. Ho Chi Minh City sits between 8.3 and 13.1mm a day from May through October, and never drops below 0.5mm even in February. Bangkok and Phnom Penh follow the same shape. There is no dry window in the south to plan around; there is a wet season and a less wet one.

Phnom Penh peaks later than everything else on the route. Its wettest month is October, by which point Hanoi has already fallen to 6.3mm. In September the wettest point on the whole route is northern Vietnam at 14.7mm; by October that has become Phnom Penh at 12.3mm. The weather moves south as the season turns, roughly in the same direction as the route.

The practical rule: travel north to south and start in northern Vietnam between roughly November and April, when it is at its driest, accepting that the southern end will be wetter whenever you arrive. If your dates are already fixed, read the column for your month rather than the row for your country — the two ends of this route rarely have the same weather on the same day.

A note on what official travel advice does not contain

It is worth knowing what you will not find where you might expect to find it. The FCDO country pages cover warnings, entry requirements, safety and security, regional risks, health, and getting help — and nothing else. There is no climate section to check, so a travel advisory is the wrong place to look for rainfall. Use a meteorological source for weather and an advisory for everything else.

Where this route goes wrong

Assuming the borders are open in both directions at the same hours. They are not always, and the information changes. Check, do not assume.

Booking the whole thing forward. Every stage above assumes you can move a day either way. Pre-booking everything removes that, and it is the most common way people turn a good route into a stressful one.

Treating Laos as a checkbox. See stage 6.

Ignoring the cost of the crossings themselves. A border can cost you a day even when the crossing is short, because of the transport on both sides. Assume each country-to-country move eats a full day. On this route that is five days of your trip that are not really travel days at all.

Before you leave

Confirm current entry requirements, visa rules and any regional advisories with your own government, for every country on your route:

• UK readers: UK FCDO foreign travel advice — country-by-country pages, including entry requirements and regional risk.
• Canadian readers: Government of Canada travel advisories.
• US readers: US State Department travel advisories.
• Australian readers: Smartraveller, the Australian government’s service.

Conclusion

The route works because of its direction, not its stops. Run Vietnam north to south, cross into Cambodia, continue to Thailand, and treat Laos as an all-or-nothing loop. In that order you never reverse, you meet the weather in the most forgiving sequence, and every border comes at a point where you have already built up slack.

Work out what the trip actually costs at your pace first — our breakdown of what it costs to backpack gives you the method. And budget for the beds before the buses: on this route, where you sleep decides whether the cheap countries stay cheap, which is why the next thing worth reading is how to choose a hostel rather than another list of things to see.

One last thing before you book: a route that crosses four countries by land exposes your bag to four sets of airline and airport rules, and the strictest of them decides what you can carry. Our backpacking packing list covers exactly which items have to travel in the cabin and which will be taken off you.
