Bảy Mẫu Coconut Forest - 'Seven-Acre Forest,' also widely nicknamed 'Miền Tây thu nhỏ' ('Mini Mekong Delta') - is a wetland of water coconut palms (Nypa fruticans) in Cẩm Thanh village, 3km from Hội An Ancient Town and about 31km from Đà Nẵng, navigated by the traditional Vietnamese basket boat (thúng chai). The nickname comes from two things at once: the dense, winding network of canals and channels through the palms genuinely resembles the landscape of Vietnam's southwestern Mekong Delta, and activities here - basket boat rowing, traditional fishing, folk games - echo the culture of that region too.
Origins of the Forest
According to local tradition, migrants from the Mekong Delta brought water coconut seedlings here around 200 years ago and planted them on the fertile wetland soil, and the favourable conditions let the palms spread into a forest of roughly seven mẫu (about 7 acres) - which is where the name comes from, even though the forest has since expanded to cover more than 100 hectares today.
The water coconut is a palm species that grows in brackish waterways and tidal zones, and the wetland sits at the meeting point of three rivers - Hoài, Thu Bồn, and Đế Võng - whose brackish water and tropical climate make ideal growing conditions; the Cẩm Thanh wetland is one of the largest remaining stands of water coconut in central Vietnam, and beyond its scenic and cultural value, the forest plays a real ecological role, moderating the local climate, reducing soil erosion, and sheltering aquatic species and birds.
Wartime History
During the resistance wars against France and then the United States, the dense palm cover made Cẩm Thanh one of Hội An's most important revolutionary bases, sheltering guerrilla fighters and hosting clandestine operations - the area saw heavy fighting, and the forest itself was targeted by bombing aimed at destroying that cover. One particularly striking episode, according to local accounts: on the night of 27 September 1964, local forces staged an uprising using rifles fashioned from coconut fronds and a show of noisy, large-scale troop movement to convince occupying forces that regular army units had arrived to liberate the area - a deception said to have helped the uprising succeed.
The Forest Today
Replanting after the war restored the forest, and the site was developed into an ecological and tourism resource from the 2000s onward. Today the wetland is navigated by basket boats through narrow waterways beneath interlocking palm fronds, and the experience - paddling through the tunnel of green vegetation with fish often visible in the clear water below - has become one of the most distinctive activity offerings near Hội An, alongside its recognised status as a wartime historical site.
