Climb down off the bridge into the banana fields mid-river
Farmland in the middle of the capital
A long low island of banana groves, vegetable plots and dirt tracks in the middle of a wide river, with the city on both banks and the steel bridge overhead.
Why it's unique
Bai Giua is a large silt island in the middle of the river, directly under the old bridge, and it is farmed — bananas, vegetables, a few smallholdings — by residents of a capital city of several million. You reach it by walking out onto a hundred-year-old bridge and taking a flight of steps down.
Working agricultural land mid-river inside a capital, accessed off a colonial rail bridge, is not an arrangement that exists in many places.
Before you go
The way down is a set of steps partway across the bridge on the upstream side and it is easy to walk past — look for the gap in the railing rather than for a sign.
Check the season before you plan around it. The island is roughly 24 hectares of silt and it goes under water during the flood season, broadly early June to late July, so for a couple of months a year there is nothing to walk on. Outside that, go in daylight and not straight after heavy rain, because the paths are mud and the river level moves enough to change what is walkable.
There is an unofficial swimming spot residents use, including a well-known nudist corner. It is somebody's routine rather than an attraction, so leave it alone. Take water; there is nothing on the island.
