Mekong Delta

Where Vietnam runs out and the river carries on

A border town on the Bassac river with floating fish farms under the houses, a Cham Muslim village across the water, and the best-known river crossing in this part of Asia.

Orientation

What Chau Doc is

Chau Doc sits where the Bassac — the second of the two big Mekong branches — crosses into Vietnam from Cambodia. That position explains everything about it: the town is a trading place, the population is a mix of Khmer, Cham and Vietnamese, and the river is full of floating houses with fish farms suspended in cages beneath them.

It is a one-night town. The fish farms and the Cham village fill a morning by boat, Sam Mountain fills a late afternoon, and by the following morning you are either driving back into the delta or boarding a boat for Cambodia.

Nights: 1
From Saigon: 4 hours
From Can Tho: 2 hours
To Phnom Penh: 5-7 hours by river
Best months: September to April

What to do

What to do here

The floating fish farms — houses with a hatch in the floor and several tonnes of basa below it. You lift the hatch and the water boils. Genuinely surprising, and a ten-minute boat ride.
Chau Giang, the Cham village — a Muslim community across the river, with wooden mosques, stilt houses and a weaving tradition. Dress modestly and ask before photographing people.
Sam Mountain at the end of the day — 230 metres, a road to the top, pagodas on the way up and a view over rice fields that runs straight into Cambodia.
Ba Chua Xu temple at the foot of the mountain — one of the busiest pilgrimage sites in the south and a completely different kind of Vietnam from anything on the tourist route.

To Cambodia

The crossing to Cambodia

The river route to Phnom Penh leaves Chau Doc in the morning and takes five to seven hours depending on the boat, with border formalities on the water at Vinh Xuong and Kaam Samnor. It is a genuinely good day: the river is wide and busy, the landscape changes gradually, and it is one of the few land borders anywhere that feels like a journey rather than a queue.

The detail that goes wrong

Cambodia’s e-visa is not valid at every land and river gate. Arriving at this crossing with the wrong visa type is the single commonest way a border day is ruined. We check the gate against your passport before anything is booked.

Practical

Practical and timing

September to November is the high-water season and the most striking time to be here, with the fields under water and the boat traffic at its heaviest. December to April is dry and easier. The town is small, the hotels are modest, and the one riverside hotel with a view is worth the small premium.

Skip Chau Doc if you are not crossing to Cambodia and have already had a delta night elsewhere — it is a long way west for a repeat of the same landscape. It earns its night either as a border stop or as the second half of a two-night delta leg from Can Tho.

Common questions

Questions travellers ask most

Is Chau Doc worth a night on its own?

It is worth a night if you are crossing to Cambodia, or as the second delta night after Can Tho. On its own, from Saigon and back, it is a long drive for a short town.

How long is the boat to Phnom Penh?

Five to seven hours depending on the boat, including border formalities on the water. Morning departures only.

Can I climb Sam Mountain?

There is a road and there are steps. Most people drive up and walk down through the pagodas, which takes about an hour and is the better way round in the heat.

Is the fish farm visit touristy?

The farms are working businesses and the visit is short and unstaged. It is one of the more genuinely interesting fifteen minutes in the delta.
