Ben Tre's topographical shape looks like an ososceles triangle, lying on the West-North and South-East axis, with its base conjoining on the South China Sea. The total length of coastline is 65 km. The two side lines of the triangle is contoured by the Co Chien River and Tien River, which are also the natural borders between Ben Tre and Tra Vinh and Tien Giang provinces, respectively, while the North vertex borders Vinh Long province.
