Ben Tre is located at the endstream of Mekong River, contiguous to the South China Sea, where there are 4 out of 9 "Dragon Mouths" opening to the sea. The total length of the province's river system is estimated at more than 6,000 km, in which Co Chien River is 82 km, Ham Luong River is 71 km, Ba Lai River is 59 km, and Tien River (or My Tho, Rach Mieu River) is 83 km long. This densely distributed system is not only very convenient for waterway traffic but also provides the land with abundant aquatic and irrigational resources.
