Tram Chim National Park supports one of the last remnants of the Plain of Reeds wetland ecosystem, which previously covered some 700,000 ha of Dong Thap, Long An and Tien Giang provinces. The national park is located 19 km to the east of the Mekong River, at an elevation of about 1 m. The topography of the national park is flat, and slopes slightly to the east. In the past, several natural streams and rivers flowed from west to east, distributing water from the Mekong River to the Plain of Reeds. Now these streams and rivers have been replaced by a system of canals, some of which flow through the national park.

The Park has a forest of Cajuput and hearth of many kind of birds with specific floristic composition: cajeput, reeds, lotus, water lily, ghost rice, rush …; plentiful fauna: python, turtles, eels, snakes, fresh-water fishes, and water bird as storks, herons, spot-billed ducks, water chicken … especially red-headed, bare-necked cranes coming in dry season each year.

From January to May each year, when sky is clear, visitors will see from the horizon many black spot coming. It is crane flock returning after months of emigrating to evade flood. This is also the season, when tourists come to Tram Chim for seeing, photographing cranes in the dawn and sunset.

Tram Chim - a reduced model of Dong Thap Muoi - with natural history of collective ecology of geomorphology, hydrograph and underwater creatures, is an ideal rendezvous place of tourists from all over the world.
