Thailand, Cambodia & Vietnam tours
One region, three countries, and a border crossing that most itineraries make harder than it is. We run these through our own offices in Bangkok, Siem Reap and Hanoi, so the handover between countries is a person, not a voucher.
Multi-country tours combine Thailand with Cambodia, Vietnam and Laos through our own offices in Bangkok, Siem Reap and Hanoi. Border crossings are handled by the same company on both sides, which is the part most itineraries get wrong. Routes run 14 to 24 days.

Three that work
Thailand & Cambodia, 12 days
Bangkok, Ayutthaya, Siem Reap, and a beach at the end. The border at Aranyaprathet is the ugly part of this route — we use the flight instead, which costs $95 and saves four hours of queueing and a scam or two.
Thailand, Cambodia & Vietnam, 15 days
Bangkok, Chiang Mai, Siem Reap, Hanoi, Halong Bay. Three flights. This is the version most people mean when they say Indochina, and it is a lot of movement — we build in two free days.
Thailand & Laos, 14 days
Bangkok, Chiang Rai, the Mekong slow boat to Luang Prabang, and back through Vientiane. The slow boat is two days and it is the point of the trip. Not for anyone who needs a schedule.
What changes at a border
Visas, currency, SIM cards, and the fact that your guide does not cross with you. We hand you to a guide on the other side, with the new documents ready. That handover is the whole value of booking a multi-country route through one operator.
| Route | Days | Countries | From |
|---|---|---|---|
| Thailand & Cambodia | 12 | 2 | $2,820 |
| Thailand, Cambodia & Vietnam | 15 | 3 | $3,680 |
| Thailand & Laos (Mekong) | 14 | 2 | $3,150 |
| Full Indochina | 21 | 4 | $5,180 |
Thailand is visa-exempt for most Western passports for 30 days (the 60-day scheme ended on 15 September 2026). Cambodia and Laos issue e-visas online in about three days. Vietnam needs an e-visa arranged 2–3 weeks ahead. We prompt you at the right moment rather than leave it to the week before.
Two countries is usually better than three
Every country you add costs you a flight day, a border day and a settling-in day. Three countries in fourteen days is a slideshow; two in fourteen is a trip. If it is your first time in the region, pick Thailand plus one.
And if you only have ten days, do not leave Thailand at all. The north and the islands are two different countries already.
Do we need separate visas?
Yes, one per country. We list exactly what to apply for, when, and what it costs, at booking.
Is the border crossing difficult?
The Poipet crossing between Thailand and Cambodia is genuinely unpleasant. We fly instead where the schedule allows. The Laos crossing at Chiang Khong is calm.
Does the same guide stay with us?
No — each country has its own licensed guides, which is a legal requirement. We introduce the next guide a day early so the handover is warm.
Can we do this with children?
From about ten, yes. Below that, two countries maximum and fewer internal flights.
The border problem
Most multi-country itineraries in this region are assembled by three separate operators who have never spoken to each other. The result is a handover day: one company drops you at a border, another picks you up two hours later, and nobody is responsible for the gap. We run offices in Bangkok, Siem Reap and Hanoi, so the same company is on both sides of every crossing.
Visas, honestly
Thailand is visa-exempt for most Western passports for 30 days, and there is now a cap of two visa-exempt entries per calendar year — which matters on a route that crosses back into Thailand. Cambodia requires an e-visa ($36) or visa on arrival, Vietnam an e-visa ($25) for most nationalities, Laos a visa on arrival ($30–42 depending on nationality). We arrange the e-visas as part of the booking because the websites are slow and reject photographs for no stated reason. Rules change; we check yours at booking and tell you the current fee rather than quoting a number that was true last year.
What the routes look like
The classic is 14 days: Bangkok, Siem Reap for Angkor, and northern Vietnam, with two flights and one land crossing. The 24-day version adds Laos and the Thai north. What we do not do is four countries in ten days, which is a coach trip with temples rather than a holiday.
How many countries, how many days?
We will tell you honestly if the combination fits the time you have.
