Cam Nam Hoi An 2026: The Clam Sandbar Over the Bridge, and the One Hoi An Eating Street a Car Can Stop On

Guests ask for the Old Town's great dish and we take them to the Old Town. Then they ask what we eat, and the answer is a kilometre south, over a bridge, on a street most itineraries never name — and one the car can actually stop on, which is not a small thing in a town built around a grid no vehicle enters.

What is Cẩm Nam, and why does the food only exist here?

Cẩm Nam is an island of silt. The Hoài — the lower branch of the Thu Bồn that runs past the Old Town quay — has been dropping its load here every wet season for centuries. Locally it goes by a nickname rather than its map name: Cồn Hến, the clam sandbar.

The geography is the recipe. Cẩm Nam sits where fresh water off the Trường Sơn meets salt pushing up from Cửa Đại, and Vietnamese press has said for years that the small clams in that brackish bed come out sweeter and firmer than clams from elsewhere. The same silt leaves sandbanks that grow sticky corn. One island, two crops, both eaten within a few hundred metres of where they come out.

One housekeeping note, because it changes how an address is written. Since 1 July 2025, under Nghị quyết 1659/NQ-UBTVQH15, there is no ward called Cẩm Nam: it was merged with Minh An, Cẩm Phô, Sơn Phong and Cẩm Kim into a single phường Hội An of 10.81 km² and about 37,222 people — one of four units, with Hội An Đông, Hội An Tây and xã Tân Hiệp, that now make up Hội An inside Đà Nẵng city. Everyone still says Cẩm Nam. Your booking form may not.

What exactly are bánh đập and hến trộn?

Bánh đập is a two-texture trick. A bánh tráng nướng — a rice cracker grilled over coals until it blisters — is laid against a bánh ướt, a soft sheet of steamed rice batter, often with a smear of scallion oil between. Then you clap it; đập means to strike. The brittle half shatters into the soft half and folds into one chewy, crackling mouthful, dipped in mắm nêm, the thick fermented anchovy sauce of Quảng, cut with chilli, garlic and pineapple. That sauce is why the dish tastes like this region and no other.

Hến are the clams, thumbnail-sized and cooked by the bowlful. Hến xào is the hot version, stir-fried with onion, herbs, chilli and crushed peanut; hến trộn is the same clam tossed cool, like a salad. Either way the plate arrives with a stack of rice crackers and no spoon: you scoop. One plate of clams and one bánh đập a head is the island's standard order, for roughly the price of an Old Town coffee.

Who actually gets the clams out of the river?

People working against the tide, at night. Rakers wait for low water before the beds are reachable, so the shift runs from dark into early morning — which is why the clams on an afternoon plate were in the river before breakfast.

The method has shifted inside living memory. Hội An's heritage centre describes the old way plainly: a bamboo rake dragged by a person wading backwards through the shallows, which is where the trade's wry local name — the backwards job — comes from. Most boats now work a long iron-edged scraper from a motorised hull. What has not been mechanised is đãi hến, the rinsing and sorting, still done by hand in flat baskets at the water's edge.

It is also a trade under pressure: Báo Đà Nẵng reports local families leaving the work to people who come in from elsewhere, and beds once reliably rich now sitting as bare mud. The best eating months are traditionally the second and third lunar months — March into April.

Why is corn the island's other crop?

Because the same floods that make the clams make the sandbanks. Cẩm Nam's bắp nếp, young sticky corn grown on the alluvial flats, turns up boiled from a basket, grilled over coals, and most famously as chè bắp — a warm, loose sweet soup of milky kernels, barely sweetened, eaten from a glass at the end of a bánh đập lunch.

The island has made a festival of it. The Ngày hội bắp nếp Cẩm Nam has run since 2014; the 2026 edition was held on 21 and 22 March at the Thanh Nam neighbourhood sports ground, opening with a lễ tế Thần Nông rite to the god of agriculture and running OCOP produce stalls, folk dance, a farmers' singing contest and lantern floating on the river. The food zone kept 08:00 to 22:00 on the Saturday and 08:00 to 11:00 on the Sunday, working the full repertoire: corn grilled, popped, stir-fried, in soup, in fritters, as chè and as corn wine. Nothing is published for 2027 yet; past editions have landed in mid-March, which is also the clam season, and that is not a coincidence.

How do you get there, and where does the car wait?

• From the Old Town perimeter: about 1 to 1.5 km, five minutes by car, out on Nguyễn Tri Phương and over cầu Cẩm Nam. On foot from the Japanese Covered Bridge it is 12 to 15 minutes.
• From An Bàng or Cửa Đại beach: about 6 km, 15 minutes.
• From Đà Nẵng airport or the city: about 30 km, 40 to 50 minutes — the ordinary Hội An corridor, plus the bridge.

Cầu Cẩm Nam is an ordinary road bridge, which means that unlike the heritage grid — where no car goes at any hour, pedestrian window or not — these kitchens sit on a street a vehicle can pull into. The strip is narrow and thick with motorbikes, so a sedan stops close to the door and a larger van waits at the wider far end; either way your driver is a hundred metres off, not across a river. Keep on along Duy Tân, river to your left, and the same road reaches the 630-metre Cẩm Kim bridge and the carpenters at Kim Bồng — the natural half-day.

Our own timing preference is late afternoon: the kitchens work all day, but local families fill the strip from about 16:30, the light goes gold on the water, and the clams are still from that morning's low tide.

What do the flood weeks do to this street?

They close it briefly, and then it comes back faster than you would believe. Cẩm Nam is the lowest ground in Hội An, and October and November are its weeks. In November 2023 water stood over a metre in places and schools shut across Cẩm Nam, Cẩm Kim, Minh An and Thanh Hà. In late October 2025 the crest at Hội An was reported at 3.4 m — level with the 1964 Năm Thìn peak, and the third flood inside twenty days — with both sides of Nguyễn Tri Phương among the deepest in mud.

And then: by 1 November the mud was largely shifted and the Old Town was lit for visitors the next evening. That is the local rhythm, not a disaster story. In a high-water week we check the bridge and the strip on the morning, and if the island is out, the same order exists on the mainland side while Cẩm Nam dries.

The short version

Cẩm Nam is a silt island a kilometre south of the Old Town, nicknamed Cồn Hến for the clams in the riverbed around it, part of phường Hội An since July 2025. Its two plates are bánh đập, clapped between your hands and dipped in mắm nêm, and hến trộn or hến xào, scooped with rice crackers, at roughly one to two dollars each. Its sandbank corn becomes chè bắp and a March festival. Five minutes from the Old Town perimeter, thirty kilometres from the airport — and, almost uniquely in Hội An, a street where the car can wait at the door.
