Multi-country

Thailand, Cambodia and Vietnam in fifteen days

The classic three-country line across the mainland — with one leg that has to be flown, because the Thai – Cambodian land border has been shut to tourists since June 2025.

The route

The route everyone asks for, and the leg that changed

This is the line most people have in mind when they say Indochina: Bangkok, Angkor, Phnom Penh, Saigon, Hoi An, Hanoi. Until 2025 the first leg was a road — Bangkok to Siem Reap through Aranyaprathet and Poipet, a long day and a famously tiresome border. That is not an option now.

The Thailand – Cambodia land border has been closed to tourists since 23 June 2025. Poipet is shut and so is Hat Lek on the coast, and at the last check neither had reopened. There is no workaround worth having: the only land route between the two countries runs through Laos and costs three days. So this itinerary flies Bangkok to Siem Reap, which takes about an hour, and uses the saved day at Angkor instead. It is a better trip than the road version was.

Itinerary

Day by day

Day 1

Arrive in Bangkok

Met at Suvarnabhumi and driven in, about an hour depending on the traffic and the hour. Nothing is scheduled. Dinner beside the Chao Phraya and an early night is the gentlest way into a fifteen-day trip.

StayHotel near the river, BangkokMealsNone includedTravelAbout 1 hour from the airport

Day 2

Bangkok by water

Wat Arun from the water at the end of the afternoon

The Grand Palace and Wat Phra Kaeo at opening, before the heat and the crowd, then Wat Pho next door for the reclining Buddha. Cross to Wat Arun by ferry in the afternoon. We move between these by river rather than by road deliberately: the boat is faster, cooler and the better view of the city.

StayHotel near the river, BangkokMealsBreakfastOn foot5 km on hot stone

Day 3

Ayutthaya

Wat Chaiwatthanaram in the last hour of light

An hour and a half north, the capital that preceded Bangkok and was destroyed in 1767. Brick prangs, a row of headless Buddhas and one head held in the roots of a fig tree. Half a day of ruins and half a day of river, back in the city by early evening.

StayHotel near the river, BangkokMealsBreakfast, lunchTravel1.5 hours each wayOn foot4 km between the temple groups

Day 4

Fly to Siem Reap

An early night before the first temple morning

About an hour in the air. This leg used to be driven through Poipet; the land border has been closed to tourists since June 2025 and the flight is now the only sensible way between the two countries. Cambodian entry is at Siem Reap–Angkor airport, where the e-visa is accepted and a visa on arrival is also issued. The airport is well east of town, an hour’s transfer, and the afternoon is free.

StayHotel in Siem ReapMealsBreakfastTravelAbout 1 hour in the air, then 1 hour from the airport

Day 5

Angkor, in the right order

Bayon before eight, and Angkor Wat after four

Angkor Thom first, not Angkor Wat: the Bayon’s faces are best in the first two hours and the walled city absorbs a crowd. Then Ta Prohm, forty minutes, early. The middle of the day is off. Angkor Wat late in the afternoon from the west, the direction it was built to be seen from.

StayHotel in Siem ReapMealsBreakfast, lunchOn foot6 to 8 km on uneven stone

Day 6

Banteay Srei and the outer temples

The lintels at Banteay Srei at seven in the morning

Thirty-seven kilometres out, Banteay Srei is small, pink and the finest carving in Cambodia; go at opening. Preah Khan and Neak Pean on the way back are quiet at midday. This is the day the closed border bought you, and it is the best-spent day on the itinerary.

StayHotel in Siem ReapMealsBreakfastTravel1 hour each way

Day 7

South to Phnom Penh

Forty-five minutes by air, or five and a half to six hours by road. We fly it unless you want Battambang, three hours down and the best street architecture in the country, in which case we add the night. The afternoon in Phnom Penh is the riverfront.

StayHotel on or near the riverfront, Phnom PenhMealsBreakfastTravel45 minutes by air, or 5.5 to 6 hours by road

Day 8

Phnom Penh

The Angkorian sculpture in the National Museum, which is not at Angkor

Tuol Sleng and Choeung Ek in the morning, in that order, with a guide who will not perform them. Four hours together and the reason to stop here rather than fly over. The afternoon is the Royal Palace, the silver pagoda and the National Museum.

StayHotel on or near the riverfront, Phnom PenhMealsBreakfast

Day 9

Overland into Vietnam at Moc Bai

The change of country, which happens in about two hundred metres

The border day, and the only one on this route. Three to four hours southeast from Phnom Penh to Bavet, where you clear Cambodian exit control on foot with your luggage, walk the hundred metres or so across, and clear Vietnamese entry at Moc Bai. Allow 45 minutes to an hour and a half depending on coach traffic. Your Vietnamese e-visa, if you are on one, must already name Moc Bai as the entry gate and Noi Bai as the exit — decided at application and unchangeable. A Vietnamese car and guide meet you; Ho Chi Minh City is two hours on, with the Cu Chi tunnels roughly on the way if you want them.

StayHotel in District 1, Ho Chi Minh CityMealsBreakfast, lunchTravel6 to 7 hours in total, including the border

Day 10

Saigon

The basement situation room at the Reunification Palace

The War Remnants Museum in the morning — uncomfortable, one-sided, and the most honest two hours available to a visitor here — then the Reunification Palace with its 1960s interiors untouched since the day it fell. The afternoon is Cholon: the Binh Tay market, Thien Hau temple and the streets between them. The evening is yours.

StayHotel in District 1, Ho Chi Minh CityMealsBreakfast

Day 11

North to Hoi An

An hour and twenty in the air to Da Nang and 45 minutes by road. Hoi An in the late afternoon is at its best, and the first evening is free among the lanterns with nothing arranged.

StayRiverside hotel in Hoi AnMealsBreakfastTravel1 hour 20 in the air, then 45 minutes

Day 12

Hoi An old town, and then nothing

The assembly halls before ten

A guided morning through the Japanese bridge, the assembly halls and two merchant houses that are still lived in. The old town stopped being a working port in the nineteenth century and was never rebuilt, which is why it reads as a whole. The afternoon is free — tailors, the market, or twenty minutes by bicycle to An Bang beach.

StayRiverside hotel in Hoi AnMealsBreakfastOn foot3 km, flat

Day 13

North to Hanoi

A slow morning in Hoi An, then Da Nang and an hour and twenty in the air. Hanoi in winter is fifteen degrees under low cloud and feels like a different country from the one you left at breakfast, which is the correct note to end on. A loop of Hoan Kiem lake at dusk.

StayHotel in the Old Quarter, HanoiMealsBreakfastTravel45 minutes to Da Nang airport, then 1 hour 20 in the air

Day 14

Hanoi on foot

Cha ca, on the last evening

The Temple of Literature at opening and the Museum of Ethnology mid-morning, which between them explain a good deal of what you have been looking at for a fortnight. The afternoon is free. In the evening an eating walk through four or five pavement kitchens, which is the right last night: northern food is the least exported of the three cuisines on this trip.

StayHotel in the Old Quarter, HanoiMealsBreakfast, dinnerOn footAbout 4 km across the day

Hanoi, and home

Noi Bai is about 45 minutes out. If the flight is late we will hold the room and put the morning to use.

Borders

The closed border, and the one that is open

Two borders matter on this route. One of them no longer works at all.

  • Thailand – Cambodia: CLOSED to tourists since 23 June 2025, and still closed at our last check. Aranyaprathet – Poipet, which carried the Bangkok to Siem Reap road route, is shut; so is Hat Lek – Cham Yeam on the coast. There is no tourist workaround. Bangkok to Siem Reap is flown, about an hour, several times a day.
  • Cambodia – Vietnam at Bavet – Moc Bai: open, busy and straightforward. Cambodian exit on foot, a short walk, Vietnamese entry at Moc Bai.
  • A Vietnamese e-visa names your entry AND exit gates at application and they cannot be changed afterwards. On this route that means Moc Bai in and Noi Bai out, both written on the form weeks before you travel. This is the most common way a self-planned version of this trip fails.
  • Thai entry is by air on the visa exemption, which has been 30 days rather than 60 since 15 September 2026. The Thailand Digital Arrival Card is compulsory, free and filed within three days.
  • Cambodian entry is at Siem Reap–Angkor airport, where the e-visa is accepted and a visa on arrival is also issued in US dollars cash. The e-arrival card is required for flights.
Checked 20 September 2026

We check the Thai – Cambodian gates against both governments and against operators on the ground before every departure, and we will tell you the moment that changes. We do not publish visa fees; the current figures are on the official portals and your coordinator confirms them in writing before you travel.

What it costs

TravellersComfortable hotelsBoutique and luxury
2 travellersOn requestOn request
4 – 6 travellersOn requestOn request
Every route is quoted for your own dates, party size and hotel standard, itemised.

Three countries means three sets of guides, three vehicles and four internal flights, and the fixed costs are higher here than on a two-country route of the same length. The hotel column is still the larger variable; ask for both and compare before you choose either.

Included

What is included

What the price includes

  • Private air-conditioned car and driver in each country, with a separate Vietnamese vehicle from Moc Bai onwards.
  • English-speaking local guides: one in Thailand, one in Cambodia, one in Vietnam, each licensed in their own country.
  • Internal flights as listed — Bangkok to Siem Reap, Siem Reap to Phnom Penh, Ho Chi Minh City to Da Nang and Da Nang to Hanoi — in economy with checked baggage.
  • Fourteen nights of accommodation with breakfast.
  • Lunch at Ayutthaya, on the first Angkor day and on the border day; dinner on the Hanoi eating walk.
  • Entrance fees to everything named in the day-by-day: the Grand Palace and Wat Phra Kaeo, Wat Pho, Wat Arun, the Ayutthaya historical park, the three-day Angkor pass, Banteay Srei, Tuol Sleng, Choeung Ek, the Royal Palace, the National Museum, the War Remnants Museum, the Reunification Palace, the Cu Chi tunnels, the Hoi An old town ticket and the Temple of Literature.
  • Boat trips: the Chao Phraya ferries in Bangkok, and the river boat at Ayutthaya.
  • All airport and border transfers, including the handover of vehicles at Moc Bai.
  • A coordinator on a local number for the whole trip, with the Thai arrival card, the Cambodian e-arrival card and the Vietnamese pre-arrival declaration explained and timed for you.

What it does not include

  • International flights into the first city and out of the last.
  • Visa fees for every country on the route. We do not publish these figures — the current ones are on each government’s official portal, and your coordinator confirms them in writing before you travel.
  • Travel insurance, which we ask every traveller to hold.
  • Meals not named in the day-by-day, and all drinks.
  • Tips for guides, drivers and boat crew.
  • Personal expenses: laundry, telephone, spa treatments, anything bought.

Honesty

Who this route is not for

Fifteen days across three countries is a lot of moving, and it suits fewer people than the number who ask for it.

  • Anyone who wanted the overland Bangkok to Siem Reap crossing. It does not exist any more. If travelling entirely by land is the point of the trip, take Vietnam and Cambodia, or Cambodia and Laos, and leave Thailand out.
  • Travellers who dislike flying. There are four internal flights in fifteen days and the route cannot be built with fewer.
  • Anyone who wants to unpack. Six places in fourteen nights, and the longest stay is three. If that reads badly, a fortnight in two countries is the better trip and we will build it.
  • Anyone looking for a beach. Two nights near the sand at Hoi An, and nothing else on the whole route.
  • Travellers in September or October who need certainty. Central Vietnam takes typhoon tails in those weeks and flights into Da Nang are the ones that move. We build in margin; we do not promise the weather.

Three countries, and the border we fly over.

Common questions

Questions travellers ask most

Why can we not drive from Bangkok to Siem Reap?

Because the Thailand – Cambodia land border has been closed to tourists since 23 June 2025 and remains closed. Aranyaprathet – Poipet and Hat Lek – Cham Yeam are both shut. The flight takes about an hour and runs several times a day, and the day it saves goes to Angkor.

Is the border likely to reopen?

We do not know, and anyone who tells you they do is guessing. We check both governments and our operators on the ground before every departure, and if it reopens we will say so and offer the road version again. Until then this route flies that leg.

Can we do it in reverse, Hanoi to Bangkok?

Yes. The only material change is the Vietnamese e-visa, which would then name Noi Bai as the entry gate and Moc Bai as the exit — again, decided before you apply. The flight from Siem Reap to Bangkok is the same hour in the other direction.

Is fifteen days enough for three countries?

It is the minimum we will build this shape in. Fourteen nights across six places is already a lot of movement; below that you would be spending a quarter of the trip in transit. With eighteen days we would add Ha Long Bay and a third Hoi An night rather than a fourth country.
