Angkor to the Thai north, flown
Three nights at Angkor, two in Phnom Penh, three in Bangkok and four in Chiang Mai. Every leg between the two countries is flown, because since June 2025 there is no other honest way to do it.

Who this journey is for
Every official crossing between Thailand and Cambodia has been shut since 23 June 2025 — Poipet–Aranyaprathet, Cham Yeam–Hat Lek, O’Smach–Chong Jom and Ban Pakard–Pailin. Armed clashes followed in July 2025 and again in December 2025. The ceasefire is holding through 2026, but Thai authorities have said there is no plan to reopen the crossings during this year. Anyone still selling a Siem Reap to Bangkok overland day is selling a flight they have not told you about, or a trip they cannot run. This itinerary flies Phnom Penh to Bangkok, it is priced that way, and it will not change if the border stays shut.

This pairing suits travellers who want the two things Southeast Asia does best at opposite ends of one trip: the largest religious monument ever built, and a northern Thai town small enough to walk. It is thirteen days, four places, and no stop shorter than two nights.
The shape matters. Five nights of Cambodia at the front is temple-heavy and emotionally heavy — Angkor in the mornings, then S-21 and Choeung Ek. Four nights in Chiang Mai at the back is the counterweight. Most operators put two nights there and treat it as an add-on; we give it four because after the first eight days you will want somewhere to stop, and Chiang Mai is where the trip should stop.
It is also the route most affected by the closed border, which is why the warning sits at the top of this page rather than in the small print. Every leg between the two countries is flown. That is not a preference, it is the only lawful way to make the journey in 2026.
What the thirteen days give you
- A three-day Angkor pass at USD 62, valid on any three days within ten, used across two mornings with the third in reserve.
- Banteay Srei on its own morning, 37 kilometres out, where the pink sandstone carving is finer than anywhere else in the park.
- Two nights in Phnom Penh, enough for the palace and the riverfront as well as the difficult morning.
- A 1 hour 20 minute flight from Techo International to Bangkok, booked in advance, with no land border and no pretence about one.
- The Grand Palace at 500 baht and Wat Pho at 300 baht, entered at 08:30 when the gates open rather than at eleven.
- A long-tail boat through the Thonburi canals, which is the half of Bangkok that still faces the water.
- Four nights in Chiang Mai: Doi Suthep, the walled city temples, a day in the hills east of town and one day with nothing scheduled at all.
- A private English-speaking guide and driver in Cambodia and a second pair in Thailand.
Two airports, and why the flight is not optional
Phnom Penh’s international traffic moved to Techo International Airport on 9 September 2025. It sits 19 kilometres south of the city and the old airport now takes domestic flights and private jets only. That transfer is about 40 minutes with traffic and it is in the itinerary and in the price. Travellers who booked before the move sometimes still have the old address in their notes; ours are current.
From Techo, Bangkok is about 1 hour 20 minutes in the air. Siem Reap to Bangkok is roughly the same. Both are ordinary scheduled flights on routes with several departures a day. The alternative — a day on the road through Poipet — is not slower or less comfortable in 2026. It is closed.
The Thai visa exemption for the sixty eligible countries and territories drops from 60 days to 30 on 15 September 2026, with one extension of up to 30 further days available at a Thai immigration office. Visa-exempt land entries are capped at twice a calendar year; air arrivals are uncapped, which is what you will be. The Thailand Digital Arrival Card is mandatory and free and must be filed within 72 hours of arrival at tdac.immigration.go.th — sites that charge for it are not official. For Cambodia: e-visa at USD 30 plus USD 6 processing, about three working days at evisa.gov.kh, or visa on arrival at USD 30, plus the free Cambodia e-Arrival form at arrival.gov.kh.
November to February is the window for this route. Cambodia is dry and the temperature at Angkor is bearable; Thailand is at its coolest. March to May puts Angkor at 35 to 40 degrees and puts Chiang Mai inside the burning season, which runs from late January to late April and peaks in March — PM2.5 in Chiang Mai reached 188 micrograms per cubic metre on 29 and 30 March 2026, twelve times the WHO guideline. Four nights in the north in March is four nights of smoke. September and October are the wettest months in Cambodia.

Day by day
Arrive Siem Reap
Siem Reap–Angkor International opened in October 2023 and sits 40 to 50 kilometres from town, so the transfer takes 45 to 60 minutes. Your guide meets you inside the terminal.
Nothing else is scheduled. Dinner is in the hotel or a short walk from it, and the Angkor pass is bought this evening at the Apsara Road office if you land in time.
Angkor Wat and the walled city
You are at the gate at 07:30 when the park opens and inside Angkor Wat before the heat. The pass carries your photograph, costs USD 62 for three days and is not transferable. Shoulders and knees must be covered at the inner entrances; the guard on the upper level turns people away for it every day.
Angkor Thom fills the afternoon: the Bayon and its face towers, the Terrace of the Leper King, and Ta Prohm strictly on the boardwalks.
Banteay Srei, then an afternoon off
Banteay Srei is 37 kilometres north-east and worth its own early start. The carving in pink sandstone is the finest in the park and the temple is small enough that arriving first genuinely changes the visit.
On the way back you stop at Pre Rup or Banteay Samre. The afternoon is free, with one pass day still unused if you want a third morning tomorrow instead of a lie-in.
Fly to Phnom Penh
A 45-minute flight lands at Techo International, 19 kilometres south of Phnom Penh and about 40 minutes from the centre. The old airport handles only domestic and private traffic now.
The afternoon takes in the Royal Palace and the Silver Pagoda, floored with five tonnes of silver tiles, and the riverfront where the Tonle Sap meets the Mekong.
The difficult morning, and what follows it
Tuol Sleng, the school the Khmer Rouge turned into security prison S-21, then the killing field at Choeung Ek 15 kilometres out. Three hours, hard from the first room. It can be declined at breakfast with no argument and no change to the price, and your guide will take you to the National Museum instead.
The afternoon is deliberately light: the Central Market under its 1937 dome, or the riverfront, or nothing.

Fly to Bangkok
Techo International to Suvarnabhumi takes about 1 hour 20 minutes. File your Thailand Digital Arrival Card within 72 hours of arrival at tdac.immigration.go.th before you leave the hotel; it is free and takes ten minutes.
A Thai guide and driver meet you at the airport. The evening is free. Bangkok after Phnom Penh is a change of scale that does not need explaining.
The Grand Palace, Wat Pho and the river
You are at the palace gate for 08:30 when it opens, because by ten the courtyards are shoulder to shoulder. Entry is 500 baht, the ticket office closes at 15:30 and the dress code is enforced at the door. Wat Pho and the reclining Buddha follow at 300 baht, ten minutes away on foot.
The afternoon runs up the Chao Phraya on the public express boat, with Wat Arun on the Thonburi bank.

The canals, and an afternoon of your own
A long-tail boat works two hours through the Thonburi khlongs: wooden houses on stilts, a temple landing every few hundred metres, and monitor lizards on the bank. This is the Bangkok that still faces the water rather than the road.
The rest of the day is unscheduled. Jim Thompson’s house, the National Museum, and Chinatown after dark are what we would suggest, in that order.
Fly to Chiang Mai
The flight north takes about an hour and fifteen and the airport is four kilometres from the old city, which makes the arrival almost effortless.
The afternoon stays inside the walls: Wat Phra Singh, Wat Chedi Luang with its earthquake-broken brick tower, and the lanes between them. The Sunday walking street runs along Ratchadamnoen if your dates catch it.
Doi Suthep, early
Doi Suthep stands at 1,050 metres, 15 kilometres above the city up a road of switchbacks, and then 306 steps flanked by naga balustrades. Go at eight and the terrace is yours; go at eleven and it is not.
The afternoon is free. Most people take a cooking class that starts in a market at nine the next morning instead, and spend today asleep.

The hills east of town
Mae Kampong is an hour east at 1,300 metres, a village of about 130 households that grew coffee and fermented tea leaves long before anyone drove up to look at it. The walk through it takes an hour and the stream runs under the houses.
The alternative is Doi Inthanon, Thailand’s highest point at 2,565 metres, which is a longer day and a colder one. Your guide will put the choice to you the night before.
Chiang Mai, unscheduled
Nothing is planned. The car and guide are on call from nine and most people use neither.
A cooking class, the Lanna Folklife Museum, the silversmiths on Wualai Road, or a chair in a courtyard. This day exists because thirteen days that end on a schedule are thirteen days you come home tired from.
Depart Chiang Mai
A transfer to the airport, five kilometres and twenty minutes, timed to your flight. Most connections go through Bangkok; there are also direct services to Singapore and Taipei.

Who this journey is wrong for
Five kinds of traveller should look elsewhere, and saying so now saves a month of planning.
- Anyone who wants to cross between Thailand and Cambodia by land. Every official crossing has been closed since 23 June 2025 and Thai authorities have said there is no plan to reopen during 2026.
- Anyone who has been quoted an overland Siem Reap to Bangkok day by another operator and wants us to match it. We will not quote a leg that cannot legally be driven.
- Anyone travelling in March, when Angkor runs at 35 to 40 degrees and Chiang Mai spends four nights under smoke from the burning season.
- Anyone who wants beaches. There is no coast on this route, and the Cambodian coast is not somewhere we send people.
- Anyone travelling on under USD 200 per person per day. Three internal flights and two full guide teams cannot be delivered at that number.

Questions travellers ask most
Can we drive from Siem Reap to Bangkok?
No. Every official Thailand–Cambodia land crossing has been closed since 23 June 2025, including Poipet–Aranyaprathet, Cham Yeam–Hat Lek, O’Smach–Chong Jom and Ban Pakard–Pailin, following armed clashes in July and December 2025.
The ceasefire is holding in 2026 but Thai authorities have said there is no plan to reopen this year. If another operator has quoted you an overland day on this route, ask them which crossing they intend to use.
Which airport does Phnom Penh use now?
Techo International Airport, 19 kilometres south of the city, which took over all of Phnom Penh’s international traffic on 9 September 2025. The old airport now handles domestic flights and private jets only.
The transfer runs about 40 minutes with traffic. Allow a little more margin than you would have needed at the old airport, and check that any flight booked independently shows the new code.
Why four nights in Chiang Mai?
Because the first eight days are temple-heavy and, in Phnom Penh, emotionally heavy. Four nights at the end gives Doi Suthep, the walled city, a day in the hills and one day with nothing in it at all.
Two nights in Chiang Mai is enough to visit it. Four is enough to stop, which is what this route is shaped around.
What do we need to enter Thailand in 2026?
From 15 September 2026 the visa exemption for the sixty eligible countries and territories is 30 days rather than 60, extendable once by up to 30 further days at a Thai immigration office. Thirteen days is well inside it.
The Thailand Digital Arrival Card is mandatory and free, filed within 72 hours of arrival at tdac.immigration.go.th. Any site charging a fee for it is not official.
