Vietnam and the neighbours
Following the river from Saigon to the temples
Ten days that go the long way on purpose: south into the delta, west to Chau Doc, then upriver by boat across the border to Phnom Penh, and on to three nights at Angkor.
Overview
Why take the river rather than the plane
A flight from Saigon to Siem Reap takes an hour and a quarter. This trip takes a week to cover roughly the same distance, and that is its point. The Mekong runs from Phnom Penh down through the whole of the delta, and following it upstream shows you how the two countries are joined: the same fish farms, the same river trade, the same floating houses, with a border line drawn across the water somewhere in the middle.
The key day is the speedboat from Chau Doc to Phnom Penh. It is five to seven hours, including the border formalities at Vinh Xuong on the Vietnamese side and Kaam Samnor on the Cambodian side, and it is one of the few border crossings in the region worth doing for its own sake.

Day by day
Ten days, in order
Day 1
Arrive in Saigon
Airport pick-up and the drive into District 1 or 3. Nothing else is scheduled; a first evening in Saigon is best spent eating near the hotel and sleeping off the flight.
Day 2
Saigon, or Cu Chi
Choose between a morning in the city — the War Remnants Museum, the palace, Ben Thanh market — or a half-day to the tunnels at Cu Chi, which is about ninety minutes each way. Either way you are back by early afternoon for the heat.
Day 3
Into the delta, to Can Tho
Leave at eight and drive south, stopping at Cai Be for two hours on the smaller canals by sampan. Lunch on the way, then on across the Hau river bridge to Can Tho, about three and a half to four hours of driving in total. An evening walk along the Can Tho riverfront.
Day 4
Cai Rang at dawn, then west to Chau Doc
A boat at half past five to reach Cai Rang while the wholesale trade is still running — later in the morning it is mostly visitors. Back for breakfast, then about three hours west to Chau Doc. In the late afternoon, Sam mountain for the view over the rice plains into Cambodia, and a sampan past the floating fish farms.
Day 5
Upriver to Phnom Penh
The river border — no queue of buses, just a pontoon and a stamp
The speedboat leaves in the early morning. You clear Vietnamese exit formalities at Vinh Xuong, cross the line on the water, and do Cambodian entry at Kaam Samnor, then continue up the Mekong into Phnom Penh, usually arriving in the early afternoon. Our Cambodian partner’s guide meets the boat. The evening is free on the riverside.
Day 6
Phnom Penh: the palace, and the harder morning
We begin at Tuol Sleng, the school that became the S-21 prison, and continue to the killing field at Choeung Ek, about forty minutes south. Both are handled quietly and with an audio guide, and we do not rush them or schedule anything cheerful straight afterwards. After lunch and a rest, the Royal Palace, the Silver Pagoda and the National Museum in the late afternoon.
Day 7
To Siem Reap
The road north is five to six hours with a lunch stop; a flight takes about forty-five minutes and we can swap to it if you would rather keep the afternoon. By road you see Kampong Thom province and the stone-carving villages near Kampong Kdei, and arrive in Siem Reap in the late afternoon.
Day 8
Angkor: the big circuit, in reverse
Most visitors do the grand circuit clockwise, so we go the other way: Preah Khan and Neak Pean in the morning, Ta Som and East Mebon before lunch. Back to the hotel through the midday heat, then Pre Rup at sunset.
Day 9
Angkor Wat, Angkor Thom, Ta Prohm
The central temples, timed around the crowds: Ta Prohm at opening, the Bayon mid-morning, and Angkor Wat itself in the afternoon, when the light is on its western face and the sunrise crowd has long gone.
Day 10
Leave from Siem Reap
A free morning, then the hour’s drive to the airport for your flight.

The speedboat is a scheduled service with a fixed fare, so the variable parts are hotels and the Phnom Penh to Siem Reap leg. Swapping the road for the flight on day 7 adds a fare but saves the driver’s day. The river is high and fast from August to November and low from March to May; the boat runs all year, but the timings shift by an hour or so either side.

Practical
The border day, and the rest of the practical detail
Cambodia’s e-visa is not accepted at every land and river crossing, and the Kaam Samnor gate has not always been on the list. Where it is not, the visa is issued on arrival at the post, which needs a passport photo and cash. The list changes, so we check the gate against your passport when you book and tell you exactly which route to take. Your Vietnamese visa must also be valid for the day you leave.
Pack for the boat as you would for a long coach ride: something warm for the air-conditioning, water, and whatever you need to hand, because the large bags go in the hold. There is a toilet on board but not much room to move.
Phnom Penh’s history is the reason the city is on this route, and the morning at Tuol Sleng and Choeung Ek is not optional in spirit even if it is in practice. It is not suitable for young children. In Cambodia we work with a long-standing local partner for guides and vehicles; your planning and support stay with us in Saigon.




Not for everyone
Who this does not suit
Anyone who dislikes long days sitting still: day 5 on the boat and day 7 by road are both full days of travel. If that sounds tiring rather than interesting, fly and take the shorter Saigon and Angkor week instead. It is also the wrong trip if you want to skip the heavy history — Phnom Penh is here because of it.
Common questions
Questions travellers ask most
Is the speedboat safe?
It is a scheduled service used daily by travellers and local passengers, with life jackets on board. In very high water we check the schedule the day before and delay if needed.
Can we do the whole river on a cruise boat instead?
Yes — our five-day river cruise from Saigon to Phnom Penh covers the same water more slowly, with cabins. Ask and we will join it to Angkor.
Do we carry our luggage across the border?
The boat crew handles the bags; you walk your passport through the two posts. The whole crossing usually takes under an hour.
