A visitor to Hue once remarked after his vacation here: “A visit to Hue would not be complete without a boat excursion on the gentle Perfume River, or else you cannot feel the romance of Hue”.The Perfume River (Vietnamese: Sông Hương or Hương Giang) is a river that crosses the capital city of Hue, in the central Vietnamese province of Thua Thien Hue. Perfume or Huong River is around 80 kilometers long, and owes its name to the fact that it flows through many forests of aromatic plants before reaching Hue, bringing with it a pure and fresh aroma.
