The short answer
- Two weeks is enough for a proper Vietnam and Cambodia itinerary — but only for three or four bases, not six.
- Give Cambodia 4 nights: 3 in Siem Reap for the temples, 1 in Phnom Penh if the history matters to you. Skip Phnom Penh if it does not.
- Fly, do not drive, between countries. Hanoi or Ho Chi Minh City to Siem Reap is under two hours; the overland border crossing eats two days.
- Best direction: north to south — Hanoi, Halong or Sapa, Hoi An, Ho Chi Minh City, then Siem Reap. You finish on the temples instead of racing to them.
- Best months for both countries at once: November to March. Dry in Cambodia, dry in the south of Vietnam, cool but clear in the north.
Almost every enquiry we get for a first trip to this part of Asia starts the same way: two weeks of leave, Vietnam on the list, and Angkor Wat somewhere near the top. It is a good instinct — the two countries sit side by side, the flights are short and cheap, and the contrast between them is the whole point of the trip.
The mistake is arithmetic. Fourteen days looks like a lot until you subtract two travel days at each end, three internal flights, and the fact that Vietnam is 1,650km long. Below is how we actually build a Vietnam and Cambodia itinerary that leaves you rested rather than wrung out.
How to split the days
For 14 nights on the ground, the split that works is 9 or 10 nights in Vietnam and 4 nights in Cambodia. Vietnam needs the larger share simply because it has more distinct regions; Cambodia’s headline sights are concentrated in one place.
Within Vietnam, resist the urge to see north, centre and south plus a beach. Pick three:
- North — Hanoi plus either an overnight Halong Bay cruise or two nights in the mountains at Sapa or Mai Chau. Not both.
- Centre — Hoi An as a base, with Hue and the Marble Mountains within reach. The most relaxed stop on any route.
- South — Ho Chi Minh City with a Mekong Delta day, and a natural jumping-off point for Cambodia.
If you have already decided you want a beach at the end instead of temples, that is a different trip — our guide to the best beaches in Vietnam covers where that fits.
How many days Angkor really needs
Three nights in Siem Reap gives you two full temple days with a rest morning, which is the sweet spot for most people. One temple day is enough to see Angkor Wat, Bayon and Ta Prohm; the second is where the trip gets interesting — Banteay Srei’s carvings, the jungle ruins at Beng Mealea, or the ninth-century brick towers of the Roluos group with almost nobody else there.
Two nights works if your flights are kind. One night does not: you will arrive tired, see the famous three in a rush, and leave with the impression that Angkor is crowded, which is mostly a scheduling problem rather than a truth. We wrote a full breakdown of this in Angkor in 1, 3 or 5 days.
Our 4-day Angkor Wat trip is the module we most often bolt onto a Vietnam route, and it is designed around exactly this pacing. If you want to go deeper into the country, Beautiful Angkor 7 Days adds Phnom Penh and the countryside, while Mystic Angkor and the Beautiful South reaches the coast at Kep and Kampot.
Should you include Phnom Penh?
An honest answer: it depends on what you want the trip to do. Phnom Penh is not a sightseeing city in the way Siem Reap is. What it offers is the Tuol Sleng genocide museum and the killing fields at Choeung Ek — difficult, essential context for modern Cambodia, and something a lot of travellers say afterwards was the most affecting day of their two weeks.
If that matters to you, add one night and fly out of Phnom Penh rather than doubling back. Our 4-day Cambodia tour from Phnom Penh runs it in that direction. If you are travelling with children, or you know your group wants a lighter fortnight, stay in Siem Reap and use the extra night for a slower temple schedule.
Getting between the two countries
There are three ways across, and only one of them is worth your holiday.
- Fly. Ho Chi Minh City to Siem Reap is about 1h20; Hanoi to Siem Reap around 2h. Several daily departures, and fares are usually modest. This is what we book.
- Overland via Bavet or Moc Bai. Ho Chi Minh City to Phnom Penh by road is 6 to 7 hours plus the border, so realistically a full day. Cheap, and genuinely interesting if you enjoy the process, but it costs you a night in Siem Reap.
- Mekong river boat. Slow-boat routes between the Delta and Phnom Penh exist and are lovely, but they need 2 days you do not have on a 14-day trip. Save this for three weeks.
On paperwork: Cambodia issues an e-visa online for most nationalities, and Vietnam’s e-visa system now covers stays of up to 90 days. Check current rules on the official Vietnam e-visa portal before you book, and read our Vietnam visa and entry guide for the detail. One thing people forget: if you leave Vietnam for Cambodia and come back, a single-entry visa will not let you in again. Tell your planner the shape of the route before visas are applied for.
A 14-night route that works
This is close to what we send out most often, north to south, finishing in Cambodia:
- Nights 1–3 Hanoi — old quarter, street food, a day at the Ho Chi Minh complex and the Temple of Literature.
- Night 4 Halong or Lan Ha Bay — overnight on a small cruise. Which bay to pick is a real decision; we compared them in Halong Bay vs Lan Ha Bay.
- Nights 5–7 Hoi An — short flight to Da Nang. Old town, tailors, An Bang beach, a day trip to My Son or Hue.
- Nights 8–10 Ho Chi Minh City — the war remnants museum, Cholon, and a Mekong Delta day to Cai Be or Ben Tre.
- Nights 11–14 Siem Reap — fly over, then two full temple days, a morning off, and a Tonle Sap or countryside afternoon before flying home.
Three internal flights, four bases, no day spent entirely in transit. If two weeks starts to feel tight when you map it out, our guide to how many days you need in Vietnam is a useful sanity check on the Vietnamese half.
When to go for both countries
The two calendars overlap more neatly than people expect. Cambodia’s dry season runs November to April, hottest in March and April. Southern Vietnam follows almost the same pattern. Northern Vietnam is dry but cool from November to February — pack a jacket for Hanoi in January, which surprises visitors every year.
November to March is therefore the widest window, and December to February is peak season for exactly that reason: book cruises and Siem Reap hotels early. May to October is Cambodia’s green season — the moats fill, the countryside is spectacular, crowds thin, and prices drop, with rain usually arriving in short afternoon bursts rather than all day. It is a fair trade if you are flexible. For the Vietnamese side month by month, see our best time to visit Vietnam guide.
Frequently asked questions
Is two weeks enough for Vietnam and Cambodia?
Yes, if you limit yourself to three or four bases. A comfortable 14-night Vietnam and Cambodia itinerary is 9 or 10 nights in Vietnam across three regions, plus 4 nights in Cambodia, with internal flights rather than long road transfers.
Should I start in Vietnam or Cambodia?
Most travellers do better starting in Vietnam and finishing in Siem Reap. You arrive fresh for the longer, more varied half of the trip and end on the temples, which is the emotional high point. Starting in Cambodia only makes sense if your flights are noticeably cheaper that way.
How do you travel from Vietnam to Cambodia?
Fly. Ho Chi Minh City to Siem Reap takes about 1 hour 20 minutes and Hanoi to Siem Reap about 2 hours, with daily departures. The overland crossing at Moc Bai to Bavet is possible but takes a full day, and Mekong river routes need two.
Do I need two separate visas?
Yes. Vietnam and Cambodia have no shared visa. Both offer e-visas online for most nationalities. If your route re-enters Vietnam after Cambodia, make sure the Vietnamese visa is multiple-entry.
How many days do you need in Siem Reap?
Three nights is ideal: two full temple days plus a rest morning. Two nights is workable with good flight times. One night means seeing only Angkor Wat, Bayon and Ta Prohm in a hurry.
Is it better to add Laos as well?
Not in two weeks. Adding Luang Prabang means a fourth country transfer and another two nights minimum, which pushes a well-paced route into a rushed one. Save Laos for a 21-day trip, or make it a separate journey — our Luang Prabang slow travel guide explains why it rewards time.
