Why go
Chau Doc, near the Cambodian border, feels like a different delta. The town is a mix of Vietnamese, Khmer, Cham and Chinese communities, with mosques, pagodas and temples side by side. Along the river, houses float on rafts above fish farms, and you can visit one to see the fish being fed from below the floorboards.
Sam Mountain, just outside town, is one of the most important pilgrimage sites in southern Vietnam, crowded with pagodas and temples, with views over rice fields to Cambodia from the top.
But the highlight for many travellers is the Tra Su melaleuca forest, about thirty kilometres away. Small motorboats and rowing boats glide along channels covered in a vivid green layer of duckweed, under the white trunks of melaleuca trees, with storks, herons and cormorants overhead.
The story
Chau Doc grew as a border and trading town, and its mixture of cultures reflects centuries of movement across the delta. The Cham villages on the river, with their wooden houses on stilts and their mosques, are home to a Muslim community whose ancestors came from the old kingdom of Champa further north.
The Temple of Ba Chua Xu, the Lady of the Realm, at the foot of Sam Mountain, is the centre of a popular cult. According to legend, a statue of the Lady was found on the mountain and could only be carried down by young women. Her festival, in the fourth lunar month, attracts huge crowds of pilgrims from all over the south.
The Tra Su forest is a protected wetland of melaleuca, or paperbark trees, which thrive in the flooded, acidic soils of the delta. It is an important bird sanctuary, especially during the annual flood season.
The flood season, roughly from August to November, transforms the whole region. Fields become lakes, fishing nets appear everywhere, and families harvest fish and water lilies that bloom across the flooded land.

Getting there
Buses run from Saigon to Chau Doc in about six to seven hours; some travellers break the journey in Can Tho. From Chau Doc, take a taxi or motorbike to Tra Su forest, about forty-five minutes away. Boat trips in the forest are arranged at the entrance.
