A steaming bowl of porridge comes piled with plump oysters, topped with fried shallots and shredded ginger, rice fragrance mingling with the brine of the sea — this is cháo hàu Long Sơn, the signature porridge of Long Sơn Commune, Vung Tau's 'oyster island' at the city's northern edge, and the most charming everyday dish of this floating-farm settlement.
The scale of the 'oyster island' farms, cross-referenced by state media
VnExpress Du Lịch's feature 'Một ngày ăn chơi tại đảo hàu Long Sơn' (A day of eating and exploring on Long Sơn oyster island) documents the farming and food culture of this 'oyster island' in detail; a separate 2023 feature by the state outlet Dân Việt reports that Long Sơn's oyster farmers use a 'Đại Bổ-style' farming method that draws in tourists to observe. Both pieces cite official statistics of more than 300 floating farming platforms, over 13,600 farming cages, and roughly 3,000 hectares of farmed water along the local rivers. Thanks to its proximity to the river mouth, moderate salinity, and abundant natural feed, Long Sơn produces exceptionally plump oysters, and the porridge here combines rice fragrance with the oysters' natural sweetness, finished with fried shallots and shredded ginger.
Honest clarification: not a street snack in the city center — it's a day trip you drive to
It has to be said honestly: while Long Sơn Commune is administratively part of Vung Tau city, geographically it's actually a peninsula settlement roughly 17 kilometers north of the city center, reachable only by connecting roads — it isn't a street snack you can walk to from downtown. Visiting Long Sơn for this bowl of oyster porridge is better planned as an 'oyster island day trip' rather than something you casually pick up while strolling through the city center, and this guide wants to be upfront about that geographic gap.
How to Plan the Trip
- Best planned as a half-day or full-day trip, combined with a visit to the floating farms and the Nhà Lớn Long Sơn temple.
- Freshly shucked, freshly cooked oyster porridge is the best kind — worth checking whether the shop sources its oysters on the spot.
- Shredded ginger is effective at cutting any fishy edge; those sensitive to it can ask for extra.
An Honest Look at the Geography
- Long Sơn Commune is administratively part of Vung Tau city, but geographically it's an independent peninsula about 17 kilometers north of the city center.
- It connects to the city center via the Chí Linh–Long Sơn connecting road, not accessible on foot.
- State-media-cited farming statistics (over 300 floating platforms, more than 13,600 farming cages) back up the real scale of this local industry.
Reaching a bowl of Long Sơn oyster porridge means first crossing the stretch of water separating the city center from the oyster island — but that rice-fragrant, oyster-sweet flavor makes the day trip worth it.
