Water and Salt, 3 days on the coast
Three days where the Mekong's branches meet the sea: coconut groves on the Ham Luong, sluice gates that keep salt out of the canals, an eroding shoreline, mangroves and brackish ponds, and Khmer rice villages near Tra Vinh. A trip about what a changing river does to the people at its mouth.

Who this trip is for
This is the climate trip. It is for readers who have seen headlines about the Mekong Delta sinking and salting and want to see what that looks like on the ground, without exaggeration. It suits adults with an interest in environment or development, teachers preparing a unit on rivers or climate, and university groups in geography, engineering or agriculture.
The coast is where the changes show. In the dry season, seawater pushes up the river mouths when the river is low; in March 2026 the national forecasting centre reported salinity of 4 parts per thousand 30–35 km up the Ham Luong and 35–40 km up the Co Chien, in a season the centre rated below the multi-year average. In 2020, an extreme year, the agriculture ministry's review found the 4 g/l line covering 24.5% of the delta, salt arriving nearly three months early and staying two to two and a half times longer than in 2016. Along the shore, a 2022 report counted about 286 km of the delta's 744 km coastline eroding or severely eroding. Over three days you see how farmers, villages and the province respond.
Every figure in a field-notes table comes from a named, dated source listed under the table. The questions are ours: they are the ones that tend to open a real conversation with a farmer, a boat trader or a monk, through your guide. Figures change; when a newer official figure appears we replace the old one and change the date.

Day by day
Day 1
Ho Chi Minh City to Ben Tre, and the Ham Luong
Pick-up at 07:00. The road reaches the former Ben Tre province, now part of Vinh Long province, across the Rach Mieu 2 bridge, opened in August 2025; the temporary Rach Mieu ferry stopped the next day. First stop, a coconut workshop on the edge of Ben Tre town, not for shopping but for the economics: coconut is the crop this area chose, and how a grove behaves in a salty year is the first thing to understand.
After lunch, the drive towards Ba Tri and the Ham Luong mouth. We stop at a sluice gate on a canal and, where a family is willing, at a house with its own rain tanks and freshwater pond. In the early evening, back in Ben Tre town, a forty-minute briefing with the salinity map and the field notes.
Day 2
The Thanh Phu shore, then across to Tra Vinh
Standing on an eroding bank with a farmer who remembers where the shore used to be
South to the coast near Thanh Phu, about 50 km. Here the river has run out of land: a muddy shore, a belt of mangroves in some places and bare, eroding banks in others, and dykes built to hold the line. The guide explains why a delta that receives less sediment struggles to rebuild its shore, and we talk with people who farm behind the dyke.
Across the Co Chien to Tra Vinh, about 47 km. In the afternoon, the Khmer landscape south-west of town: Ao Ba Om, a rectangular pond ringed by very old trees, and Chua Ang beside it, by tradition the oldest Khmer pagoda in Tra Vinh. The stop is about how Khmer rice-growing villages near the coast deal with salt, and how to visit a pagoda with respect.
Day 3
Brackish ponds on the Tra Vinh coast, then back
East to the coast, about 44 km. Many fields near the sea have changed from rice to brackish-water ponds, or alternate between the two with the seasons. We visit a farm where the owner explains the choice: what the water allows, what the market pays, what went wrong in a bad year.
Lunch near the coast, then the drive back through Tra Vinh to Ho Chi Minh City, about 127 km from Tra Vinh town, arriving at about 17:30. A closing discussion on the road: what you saw, which figures surprised you, and what to read next.
Field notes for this trip

| Sluice gate on a canal | Gates, a gauge board, a keeper's hut | 2020: salt arrived nearly three months early and lasted 2–2.5 times longer than 2016 (Tuổi Trẻ, Jun 2020) | Who decides when to close the gate? What happens to boats when it is shut? |
| Rain tanks and ponds at a house | Large jars and tanks, a covered freshwater pond | 2020: 10 of 13 delta provinces affected (Tuổi Trẻ, Jun 2020) | Where does drinking water come from in April? What does it cost? |
| Thanh Phu shore | Mangrove belt in places, bare eroding banks in others | About 286 km of 744 km of delta coastline eroding or severely eroding (2022 report; VnEconomy, Mar 2025) | Where was the shore twenty years ago? Who pays for the dyke? |
| The sediment question | Brown water, but less mud than it looks | Sediment load about 160 million tonnes a year before 1990, about 80 million by 2019 (MRC via VNS, Nov 2019) | Have you noticed the river water changing colour or depth? |

Who this trip is not for
- Anyone looking for dramatic scenery — this is a flat, working coast, and the interest is in the detail
- Travellers who want the classic delta of floating markets and orchards; take How the Delta Feeds Vietnam instead
- People who dislike long conversations through an interpreter; much of the trip is listening
- Travel in September to November if salinity is the main interest — that is the wet season, when the story is flooding and rain rather than salt
- Anyone who needs international-standard hotels; the town hotels are clean and simple
Common questions
Questions travellers ask most
Will we actually see salt water?
You see its effects rather than the salt itself: closed sluice gates, tanks of stored rainwater, stressed trees, fields turned into ponds. In February to April your guide can often show a salinity reading at a canal or ask a farmer for the latest local measurement.
Is the trip depressing?
It is honest, which is different. Most of the people you meet are adapting with some skill, and the trip spends as much time on their choices as on the problem.
Can we add a night on the coast?
We base the nights in Ben Tre and Tra Vinh towns so that we can name each hotel on your quote and keep the evenings for the briefing. The coast is reached as day visits from those towns.
Why do you say former Ben Tre province?
Since 1 July 2025 Ben Tre and Tra Vinh have been part of an enlarged Vinh Long province. The town names are unchanged and everyone still uses them.
